point a has coordinates (-4,2) point a is translated to the point with coordinates (-1,-3) find as a column vector the vector that describes this translation

Step-by-step explanation:

the radius of the circular base is 7/2=3.5 cm

the surface of the base is πr^2=π*(3.5)^2=38.465

volume of the cylinder is surface of the base*high

38.465*30=1153.95

the cuboid volume=8^2*x=64x

64x=1153.95

x=1153.95/65=18.03 cm=18 cm

Answer:

bro do u have a pic i will give u your points back but i need a pic to help

Step-by-step explanation:

Answer: We know that the volume of a cuboid is given by the product of its length, width and height, or V = l * w * h. In this case, the length is 250 cm and the height and width are both x cm. So, the volume can be written as:

V = 250 * x * x

Substituting the given value of V = 4840 cm³, we get:

4840 = 250 * x * x

Dividing both sides by 250, we get:

19.36 = x * x

Taking the square root of both sides, we get:

x = ±√19.36

Since the side length of a square must be positive, we use the positive square root:

x = ±4.4 cm

Therefore, the side length of the square cross-section is 4.4 cm.

Step-by-step explanation:

The perimeter of the triangle is

The perimeter of the triangle is sum of the length of the sides

The sides are solved as follows using trigonometry relations

Sin = opposite / hypotenuse - SOH

Cos = adjacent / hypotenuse - CAH

Tan = opposite / adjacent - TOA

Solving for NM using tan

tan 59 = 5 / NM

NM = 5 / tan 59 = 3

Solving for LN

sin 59 = 5 /LN

LN = 5 / sin 59 = 5.83

The perimeter of the triangle

= 5.83 + 5 + 3

= 13.82 in

Answer:

Step-by-step explanation:

Let's call the number of boys "b" and the number of girls "g". From the ratio, we know that b/g = 11/9.

Also, we know that b = g + 124, so we can substitute the second equation into the first:

b/g = 11/9

b = g + 124

g + 124 / g = 11/9

Cross multiply:

9g + 1112 = 11g

Solve for g:

-2g = -1112

g = 556

So there are 556 girls and 556 + 124 = 680 boys at the school.

The total number of students at the school is 556 + 680 = 1236.

Answer: The least number that can be made using each digit exactly once is 123456789. The value of 4 is greater than the value of 6 because in the decimal system (base 10), the position of a digit determines its value. The leftmost digit represents the greatest place value (ones, tens, hundreds, etc.) and each subsequent digit represents a smaller place value. In the number 123456789, the 4 is in the thousands place, which has a greater value than the 6, which is in the tens place.

Therefore, the 4 has a greater value than the 6 because it represents a larger place value.

Answer:

6

Step-by-step explanation:

12 is the full length. point E marks 1/2 of the line. 12-6=6

if it's asking the length of d-e, then the answer is (6) because the entire length of line is twelve and in the top line e-f in 6 and 6-12=6

The necessary equation is [tex]L= 52+2D[/tex], and the necessary overall length is [tex]114 miles[/tex].

Given: A road is being extended by construction workers. The road already had a length of miles, and the crew is continuously extending it by miles. Let the number of days the crew has worked and the distance of the entire road (in miles) be represented by D and L respectively. Create a corresponding equation L to D.

According to the inquiry,

The road's initial length is 52 miles.

The daily length of roadways that a crew adds is 2 miles.

This number represents the number of days the crew worked.

The total length of the road that the crew built is represented by L.

A given condition-based equation can be written as [tex]L= 52+2D[/tex].

Now, the crew's total length of the road after 31 days of construction is calculated.

[tex]L= 52+2*31\\L=52+62\\L=114 miles[/tex]

As a result, the needed equation and the total length is [tex]L= 52+2D[/tex]  and 114 miles respectively.

The complete question is:-

A construction crew is lengthening a road. The road started with a length of 52 miles, and the crew is adding 2 miles to the road each day. Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D .

To estimate the probability that a randomly selected person would pass the driving test on the first attempt, we can divide the number of people who passed on the first attempt (6500) by the total number of people who took the test (10,000).

Probability = Number of favorable outcomes / Total number of possible outcomes.In this case, the favorable outcome is passing the test on the first attempt, and the possible outcomes are all the people who took the test.

Probability = 6500 / 10000= 0.65

Therefore, the estimated probability that a randomly selected person would pass the driving test on the first attempt is 0.65 or 65%. This means that there is a 65% chance that a randomly selected person from the group of 10,000 would pass the driving test on their first try.

The simplified expression after rationalizing the denominator are:

1)  (17 + √3)/13.

2) -3(2+√5)/5.

What is rationalizing the denominator?

To rationalize the denominator with two terms, find the conjugate of the denominator. Then multiply and divide the fraction by the conjugate of the denominator.

1).

a) The conjugate of the denominator is 4 + √3.

b) To rationalize the denominator, we need to multiply both the numerator and the denominator by the conjugate of the denominator:

(5/4 - √3) * (4 + √3) / (4 + √3) * (4 - √3)

Simplifying the numerator:

5(4) + 5(√3) - 4(√3) - 3 / 13

= (17 + √3)/13

Therefore, the simplified expression after rationalizing the denominator is (17 + √3)/13.

2).

a) The conjugate of the denominator is 1 - √2.

b) To rationalize the denominator, we need to multiply both the numerator and the denominator by the conjugate of the denominator:

2 / (1 - √2) * (1 + √2) / (1 + 2)

Simplifying the numerator:

2(1 + √2) / (-1 + 2)

= -2(1 + √2)

Therefore, the simplified expression after rationalizing the denominator is -2(1 + √2).

a) The conjugate of the denominator is 2 + √5.

b) To rationalize the denominator, we need to multiply both the numerator and the denominator by the conjugate of the denominator:

3 / (2 - √5) * (2 + √5) / (2 + √5)

Simplifying the numerator:

3(2 + √5) / (-5)

= -3(2+√5)/5.

Therefore, the simplified expression after rationalizing the denominator is -3(2+√5)/5.

Hence, the simplified expression after rationalizing the denominator are:

1)  (17 + √3)/13.

Lauren was 13 miles away from the restaurant when Aidan reached it.

Travel refers to the act of moving from one place to another, often over a distance or by means of transportation.

Lauren and Aidan both left their offices at 6:15 P.M. and traveled for 20 minutes (from 6:15 P.M. to 6:35 P.M.) before Aidan arrived at the restaurant. During this time, Lauren traveled at a speed of 39 miles per hour, so she covered a distance of:

distance = speed x time

distance = 39 miles/hour x (20 minutes / 60 minutes/hour) = 13 miles

After 20 minutes, Aidan arrived at the restaurant, having traveled for 20 minutes at a speed of 42 miles per hour. The distance he covered during this time is:

distance = speed x time

distance = 42 miles/hour x (20 minutes / 60 minutes/hour) = 14 miles

Since they both traveled the same distance to the restaurant, but Aidan arrived there first, Lauren must have been 1 mile behind him when he arrived at the restaurant.

Therefore, Lauren was 14 - 1 = 13 miles away from the restaurant when Aidan reached it.

In order to achieve an 80% gross margin, the store would need to sell the battery chargers for $50 each - A

The gross margin is the difference between the selling price and the cost of the item, expressed as a percentage of the selling price. To achieve an 80% gross margin, we need to set the selling price such that 80% of it represents the profit on the item.

Let's call the selling price of the battery charger S. The profit on the item is S - $10, since that is the cost of the item. So, to achieve an 80% gross margin, we want:

(S - $10) / S = 0.80

Expanding and solving for S:

S - $10 = 0.80S

0.20S = $10

S = $50

So, in order to achieve an 80% gross margin, the store would need to sell the battery chargers for $50 each. That would be the sticker price for the chargers.
