Answers

Answer 1

Answer:

The equation 2n + 1 = 157 represents the situation where the sum of two consecutive numbers is 157.

To find the first number, we can start by subtracting 1 from both sides of the equation:

2n = 156

Then we can divide both sides by 2:

n = 78

So the first number is 78, which corresponds to the answer choice B.

Samir i hopping for gift online. He found two coupon code, but he can only ue one of them per purchae. The firt coupon code would give him 5% off and free hipping. The econd coupon code would give him 20% off, but he would have to pay $14. 99 for hipping. Samir want to find p, the price at which the firt coupon code give him a better deal. Which inequality can he ue?

Answers

The price p which the first coupon code give him a better deal is less than $99.93. The inequality he can use is the first coupon code will give Samir a better deal.

Inequality for Better Deal

We can find the value of "p" by solving the inequality.

Starting with the inequality:

        (1 - 0.05) * p + 0 < (1 - 0.20) * p + 14.99

This inequality compares the total cost (price minus discount plus shipping) of using the first coupon code on the left-hand side and the total cost of using the second coupon code on the right-hand side. If the left-hand side is less than the right-hand side, then the first coupon code gives a better deal.

Solving for p, Samir can find the minimum price at which the first coupon code is a better deal.

Expanding both sides:

        0.95 * p + 0 < 0.80 * p + 14.99

Simplifying both sides:

        0.95 * p < 0.80 * p + 14.99

Subtracting 0.80 * p from both sides:

       0.15 * p < 14.99

Dividing both sides by 0.15:

        p < 99.93

So, if the price "p" is less than 99.93, the first coupon code will give Samir a better deal.

Answers

In the trapezoid ABCD , when AB || DC and M, N are the midpoint of AD and BC then the value of AB , DC , and MN is equal to 26, 10, and 18 respectively.

In trapezoid ABCD,

AB || DC

AB = 7x + 5

DC = 4x -2

MN = 5x + 3

Using midpoint segment of two parallel lines in a trapezoid we have,

( AB + DC ) / 2 = MN

Substitute the value of AB, DC, and MN we get,

⇒ ( 7x + 5 + 4x -2 )/ 2 = 5x + 3

⇒11x + 3 = 10x + 6

⇒x = 3

⇒ AB = 7(3) + 5

         = 26

DC = 4(3) -2

Evaluate the function when:
x= -1, 0, and four

Equation: y= -2x-4

Answers

Answer:

To evaluate the function when x = -1, 0, and 4, we need to substitute those values into the equation and solve for y.

1. When x = -1,

y = -2(-1) - 4

y = 2 - 4

y = -2

2. When x = 0,

y = -2(0) - 4

y = -4

3. When x = 4,

y = -2(4) - 4

y = -8 - 4

y = -12

So, the function has the values of -2, -4, and -12 when x = -1, 0, and 4 respectively.

One rower and one cricketer are related. If the conditions in a apply, what is the probability that these two members of the committee will sit next to one another?

Answers

(a) Total 288 different arrangements of the committee are possible if the rowers and basketballers both sit together in groups, but no rower sits next to a basketballer.

(b) If the conditions in a apply, 1/24 is the probability that these two members of the committee will sit next to one another.

(a) Considering the four rowers as a single person, the three basketball players as a single person, and the cricketers as two unique people (So, a total of 4 persons).

Number of configurations for a round table of n people = (n-1)!

Number of configurations for a round table of n people = (4-1)!

Number of configurations for a round table of n people = 6 ways

Let's leave out the number of arrangements that the basketball players and rowers will have.

Assuming that a basketball player and a rower are one person, they will sit together = (3-1)! × 2!

Assuming that a basketball player and a rower are one person, they will sit together = 4

There are therefore numerous arrangements for the groups where basketball players and rowers sit together = 2

No. of ways to arrange basketball players in a group = 3!

No. of ways to arrange basketball players in a group = 6

There are numerous number of methods to arrange rowers within a group = 4!

There are numerous number of methods to arrange rowers within a group = 24

Hence, total number of ways = 2×6×24

Total number of ways = 288

No. of ways are 288

b) The definition of an event's probability is as follows:

Probability = No. of Successful Outcomes / Total no. of Outcomes

Number of ways a cricketer can take a seat = 2! = 2 ways

Number of arrangements for the remaining rowers when he is seated next to the cricket player = 3!

Number of arrangements for the remaining rowers when he is seated next to the cricket player = 6 ways

Total number of possible ways = 6×2

Total number of possible ways = 12 ways

Probability = 12/288

Probability = 1/24

Hence, the required probability is 1/24.

Your favorite chips cost $1.20 for 15 ounces. What is the unit rate? Enter your answer in the box. The units will be $/oz. Do not type the units

Answers

To find the unit rate, we need to divide the price of the chips by the number of ounces:  for every ounce of chips, it cost $0.08

How do I determine unit rate?

The denominator of a unit rate is always 1. Divide the denominator by the numerator such that the denominator equals one in order to calculate the unit rate.

For instance, the unit rate is 50 km/5.5 = 9.09 km/hour if 50 km are traveled in 5.5 hours. An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. 70 yards in 10 seconds and 7 yards in 1 second are both ratios, although only the latter is a unit rate.

Unit rate = Price / Number of ounces

Unit rate = $1.20 / 15 ounces = $0.08 per ounce

So the unit rate is $0.08 per ounce. This means that for every ounce of chips, it cost $0.08

Show your work and explain in complete sentences how you thought about the problem.

Answers

What I think about the problem is that there are no specific rules to tackle it, but with careful analysis I have deduced the answer for the total dots in the 50th hexagon to be 7701 dots.

How I got the figure

To find the total number of dots in the 50th hexagon, we can use the formula for finding the number of dots in the nth hexagon, where n is the number of the hexagon. The formula is:

Dots = 3n^2 + 3n + 1

Substituting n = 50, we get:

Dots = 3 * 50^2 + 3 * 50 + 1

= 7550 + 150 + 1

= 7701

So, there are 7701 dots in the 50th hexagon.

To think about the problem, we can observe that each additional hexagon added to the previous one will add 3 dots to the total count. This is because each new hexagon adds 3 sides to the previous hexagon, each side having one dot. And, each new hexagon will also add one additional dot to the center.

Body Mass Index (BMI) is calculated by dividing a person's height in meters squared by their weight in kilograms (or pounds) (or feet). A high BMI may be a sign of high body fat.

A person's body mass index (BMI) is calculated by dividing their weight in kilograms by their height in meters squared. Underweight, healthy weight, overweight, and obesity can all be detected using the BMI, which is a low-cost and simple screening approach.

Your risk of developing diseases that can be brought on by having a higher body fat percentage can be determined by your BMI. Your chance of developing certain conditions, including breathing difficulties, heart disease, high blood pressure, type 2 diabetes, gallstones, and some malignancies, increases with your BMI.

a) The formula for the rate of change of the BMI in relation to weight at a constant height is [tex]$B_w=\frac{1}{h^2}$[/tex].

b) Since [tex]$B_w=\frac{1}{h^2}$[/tex] exists always positive, we see that for fixed h, the BMI exists an increasing function of w.

c) Given a fixed weight and height, the rate of change in the BMI is given by  [tex]$B_w=\frac{-2 w}{h^3}$[/tex].

d) Since [tex]$B_w=\frac{-2 w}{h^3}$[/tex] exists always negative, we see that for fixed w, the BMI exists a decreasing function of h

he mean salary of 150 employees of an organization was found to be Rs 22500 per month.Later on ,after disbursement of salary it was found that salary of two employees was wrongly entered as Rs 25760 and Rs 19590. The correct salaries were Rs 27760 and Rs 18590.Calculate the correct mean salary paid to employees .

Answers

The average monthly pay for 150 employees was Rs 22500; however, after two employees' salaries were incorrectly inputted, the actual average monthly pay for employees was Rs 22532.

150 x 22,500 equals the total salary before correction, or Rs.

After rectification, the total salary equals

(150-2)*22500 + 25760 + 18590, or Rs. 339060.

Correct mean pay is equal to Rs. 339060 / 150, or Rs. 22532.

Initial reports stated that the mean wage for 150 workers was Rs. 22500 per month. Further examination revealed, however, that two employees' salary had been put incorrectly as Rs 25760 and Rs 19590, respectively. The two employees' actual pay were Rs. 27760 and Rs. 18590. The total salary before rectification was therefore 150*22,500, or Rs. 337,000. After two employees' pay were adjusted, the total salary was (150-2)*22500.The average monthly pay for 150 employees was Rs 22500; however, after two employees' salaries were incorrectly inputted, the actual average monthly pay for employees was Rs 22532 (150-2)*22500 + 25760 + 18590 = Rs339060. Consequently, it was determined that Rs339060 / 150 = Rs22532 was the proper mean wage paid to employees. After correcting the two incorrectly reported salaries, the average monthly wage for the organization's employees came to Rs22532.

By using the shell method to find the volume of the solid generated when R is revolved about the y-axis is V = 2π∫3⁹(11−x0)x0(11−x0−dx)dx

The volume of a solid that is generated by rotating a region about a given axis is called the volume of revolution. One of the methods to find the volume of revolution is the shell method.

Let's consider the region R bounded by the curves y = 11−x, y = 0, x = 3, x = 9 and find its volume when it is revolved about the y-axis.

The first step is to sketch the region R in the xy-plane. The curves y = 11−x and y = 0 intersect at x = 11, y = 0. The region R is a trapezoid with height 11 and bases 3 and 9.

Next, we need to find the expression for the volume of a thin shell of thickness dx, whose axis is along the y-axis.

Let us consider a thin shell at x = x0. The height of the shell at x = x0 is given by 11−x0. The inner and outer radii of the shell are given by y = 11−x0 and y = 11−x0−dx respectively.

The volume of the shell is given by the formula:

=> V = 2π(y2−y1)x0 = 2π(11−x0)x0(11−x0−dx)

We can now integrate this expression over x0 to find the total volume of the solid.

The limits of integration are x0 = 3 and x0 = 9. The volume of the solid is given by:

V = 2π∫3⁹(11−x0)x0(11−x0−dx)dx

Solving this definite integral will give us the volume of the solid.

2. A 6-sided die with the numbers 1, 2, 3, 4, 5, and 6 is rolled 42 times. What is a
reasonable prediction for the number of times the die would land with a 6 faceup?
F 4
G 5
H6
3 7

Answers

A reasonable prediction for the number of times the die would land with a 6 faceup is 7.
The die has a 1/6 chance of landing with a 6 faceup on any given roll, so if it is rolled 42 times, we would expect it to land with a 6 faceup 7 times (42 * 1/6 = 7).
So the answer is "3 7"

Triangle RST is translated so that point R (-2, 1) is mapped to point R’ (2, -4). If point S is (-4, 3), what ordered pair best represents point S’?

Answers

The coordinates of the point S after translation will be -

S'(0, - 2).

What is scaling? How is it done?Scaling is defined as the process of changing the dimensions of the original figure as per some specific proportional rule.If the initial length is equivalent to {a}. Then, after the scaling by the scale factor of {K}, the length becomes {Ka}. Similarly, if the initial coordinates are (x, y) then after scaling the coordinates would be {Kx, Ky}.

Given is that triangle ΔRST is translated so that point R (-2, 1) is mapped to point R’ (2, -4).

The triangle is translated according to the rule as follows -

(x, y) → (x + 4, y - 5)

For the point S(-4, 3), we can write -

S(-4, 3) → S'(0, - 2)

Therefore, the coordinates of the point S after translation will be -

S'(0, - 2).

Gabriela and William try to do as many pool lengths as possible in 14 minutes. Together they did 56 lengths. Gabriela went 2 lengths less than william How many lengths did William do?

Answers

Answer:

29

Step-by-step explanation:

w = # william laps

 then  w-2 = gabby's laps    together they sum to 56

w   +    w-2 = 56      add 2 to both sides of the equation

2w =58

w = 29   <=====william's laps

Answer: 29

Step-by-step explanation:

Gabriela went w -2 ( 2 lengths less than william)

William went w

Total is 56

So w - 2 + w = 56

Combine like terms: 2w - 2 = 56

Add the two ro both sides: 2 + 2 - 2w  = 56 + 2

2w / 2 = 58 / 2

w = 29

Tom had an average of 74 runs in 3 matches. if he scored 42 and 31 runs in two resent matches, what is his new average?​

Answers

Answer:

To calculate Tom's new average, you need to know the total number of runs he scored in the three matches and the total number of runs he scored in the recent two matches.

You can use the following formula to calculate the new average:

New Average = (Total Runs + Recent Runs) / Total Matches

First you need to find the total runs he scored in the first 3 matches:

74 (average) * 3 (number of matches) = 222 runs

Then you need to find the total runs he scored in the recent two matches:

42 (runs in match 1) + 31 (runs in match 2) = 73 runs

Now you can find the new average by adding the total runs in recent two matches and total runs in the first 3 matches and divide it by the total number of matches:

(222 + 73) / 5 = 295 / 5 = 59

So, Tom's new average is 59 runs.

Answer: 59

What is Alphametics?

Alphametics, also known as verbal arithmetic or cryptarithm, is a type of mathematical puzzle where letters or symbols are used to represent digits or numbers, and the puzzle solver must determine the correct digit or number to replace each letter or symbol in order to solve the puzzle.

The objective of an alphametic puzzle is to find a unique solution, where each letter or symbol represents a different digit or number, and the arithmetic equation is correct. In some alphametic puzzles, there may be additional constraints, such as leading zeros not being allowed, or certain digits being constrained to specific values.

One possible solution to this cryptarithm is:

 9 5 8 8 7 0

- 2 1 4 8 0 3

_________

7 4 4 0 6 7

In this solution, P=9, E=5, R=8, S=7, A=0, L=4, and Y=6.

To check:

PEPPER = 958870

SALT = 214803

YUMMY = 744067

And 958870 - 214803 = 744067, so the solution is correct.
