Answer:

21 = k

Step-by-step explanation:

Vertical angles are equal

170 = 6k+44

Subtract 44 from each side

170-44 = 6k+44-44

126 = 6k

Divide each side by 6

126/6 = 6k/6

21 = k

Each gallon of water weighs by itself is 8.4 pounds, option (C) 8.4 pounds is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

From the data given:

When the Amount of Water in Can (gallons) = 0

Weight of Cans (pounds) = 2

It means the weight of the can = 2 pounds

For the 0.5 gallons, the weight of the can = 6.2 pounds

For the 0.5 gallons, the weight of the water = 6.2 - 2 = 4.2 pounds

For the 1 gallon, the weight of the water = 2x4.2 pounds

= 8.4 pounds

Thus, each gallon of water weighs by itself is 8.4 pounds, option (C) 8.4 pounds is correct.

Answer:

4.259 is greater than 4.246 because its decimal places are higher values.

4.246 < 4.259

Hope that helps

to compare these two decimals we will have to compare the number in the hundredths and thousandths place becuase we already know the whole number and the tenths place number is the same. as you can see, 4.259 is greater becuase 5 tenths is greater than 4 tenths.

Answer:

Ryan had 10.20 dollars and Jeffery had 11.40 dollars.

Step-by-step explanation:

Let Ryan have x dollars originally, then Jeffrey has x + 1.20 dollars.

From the given info:

After getting 7.50 from Ryan, Jeffrey has:

x + 1.2 + 7.5 dollars and Ryan has x - 7.50 dollars.

Jeffreys money is now is 7 times as much as Ryan's, so:

x + 8.7 = 7(x - 7.5)

x + 8.7 = 7x - 52.5

8.7 + 52.5 = 7x - x

6x = 61.2

x = 10.20 dollars.

The terms of the polynomial, which has a degree of 2, are ordered as follows in decreasing order: 17x² + 27x

Sums of terms of the form  k⋅xⁿ where k is any number and n is a positive integer, make up polynomials. For instance, the polynomial 3x+2x-5.

Given polynomial: 5x + 17x² + 22x

We need to simplify this polynomial first.

5x + 17x² + 22x = 27x + 17x²

Now we will put the term with highest degree first and arrange the terms of this polynomial.

17x² + 27x

Since, the highest power of terms in this polynomial is 2.

We can say that the degree of polynomial is 2.

Therefore, the polynomial has a degree of 2 and its terms are arranged in decreasing order as follows: 17x² + 27x.

Based on the information that the smallest score in a population is x=5, and the largest score is x=10, the conclusion is that the standard  deviation is going to be smaller than the range of scores.

Given that in a population, the smallest score is x=5, and largest score is x=10, the range of scores is:

Range of scores=largest score-lowest score

                          =10-5

                           =5

Here the range of scores is 5, and the mean of the scores is likely to be between 5 and 10

Standard deviation which refers to the average spread of the distribution,  will now be considered to be smaller since the range of scores is low.

Because standard deviation is found from the mean, if the mean is between x=5 and x=10, the standard deviation must be lower than x=5.

Hence, smaller than the range of scores.

The function  f(x)= 1/2x - 2 and g(x)= -2x -4 are not inverses of each other.

An inverse function can be described as the function that can undo another function, it is relationship between two function which is not directly proportional to each other.

An inverse function will follow the expression f^{-1},

Inverse of  1(/2x - 2 ) = (2x - 2 )

Inverse of  g(x)= (-2x -4) = 1/ (-2x -4)

This implies implies that Inverse of  g(x)  ≠  f(x)

The equation that represents the graphed line is y = -3x + 2. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The kine is passing through (0, 2) and (1, -1). Then the slope of the line is given as,

m = (2 + 1) / (0 - 1)

m = -3

And the y-intercept of the line is 2. Then the equation of the line is given as,

y = -3x + 2

The result of the expression 2x+9+7x is 9x+9

The expression is 2x+9+7x

To solve this expression, first we have to rearrange the terms and do the arithmetic operations in the expression.

Expressions is the mathematical statements that have a minimum of two terms containing numbers or variables, connected by an operator in between. The operator maybe addition, subtraction, division or multiplication. To  solve the mathematical expression we have to do the arithmetic operation on like terms.

The expression is 2x+9+7x

Rearrange the terms in the expression

= 2x+7x+9

Add the like terms in the expression

= (2+7)x+9

= 9x+9

Hence, the result of the expression 2x+9+7x is 9x+9

To determine if the three numbers can be the measures of the sides of a triangle:

According to the Triangle Inequality theorem to construct a triangle, the sum of the two sides of the triangle is greater than the third side i.e x + y>z

1) 9, 7, 13

So, 9+7 > 13

16 > 13

7+ 13 > 9

20 > 9

9+13 > 7

22 > 7

Yes, they can be the measures of the sides of a triangle.

2) 26, 12, 11

So, 26+12 > 11

38 > 11

12+ 11 > 26

23 < 26

No, they cannot be the measures of the sides of a triangle.

3) 11, 2,9

So, 11+2 > 9

13 > 9

2+ 9 > 11

11 = 11

No, they cannot be the measures of the sides of a triangle.

4) 6, 11, 12

So, 11+6 > 12

17 > 9

11+12 > 6 and 12+6 > 11

Yes, they can be the measures of the sides of a triangle.

To determine the range of the third side we find the maximum value and minimum value using two sides of a triangle.

Let's assume that x is the third side of the triangle.

5) 12,9

So, the maximum value of the third side is 12+9 = 21 and the minimum value is 12-9 = 3.

Hence, the range is 3<x<21.

6) 8, 11

The maximum value of the third side is 8+11 = 19 and the minimum value is 11-8 = 7.

Hence, the range is 3<x<19.

7) 11,6

The maximum value of the third side is 11+6 = 17 and the minimum value is 11-6 = 5.

Hence, the range is 5<x<17.

8) 12,8​

The maximum value of the third side is 12+8 = 20 and the minimum value is 12-8 = 4.

Hence, the range is 4<x<20.

Step-by-step explanation:

Using Simple Interest, Ali has to pay 10241 after 3 years.

Simple interest is the interest that is accrued at a specific rate and for a specific length of time on a particular principal. It is based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued. Consider making a $100 (the principal) investment at a 5% yearly rate for a year. To calculate simple interest, multiply $100 by.05 interest per year to get $5 after a year.

If P is the principal, r is the rate, t is the time

SI = [tex]\frac{P \times r \times t}{100}[/tex]

Here,

Cost of sound system = 7700

Rate  = 11 %

Time = 3years

SI = [tex]\frac{7700 \times 11 \times 3}{100}[/tex]

  = 2541

Amount Ali has to pay after 3 year = 7700 + 2541

                                                        = 10241

b. The 95% confidence interval for the population mean amount spent on restaurants and carryout food is of ($1,750.6, $1,995.4).

c. The estimate is the sample mean of $1,873.

The bounds of the confidence interval are given according to the following rule:

In which the parameters are described as follows:

In the context of this problem, the values of these parameters are given by:

[tex]\overline{x} = 1873, s = 550, n = 80[/tex]

Hence, for item c, the estimate is of $1,873, as it is the sample mean.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 80 - 1 = 79 df, is t = 1.9905.

The margin of error is given by:

[tex]M = t\frac{s}{\sqrt{n}}[/tex]

Hence:

[tex]M = 1.9905\frac{550}{\sqrt{80}} = 122.4[/tex]

Supplementary angles sum to 180 degrees

x  = angle 1

(x+32.6 ) = angle two

x +    (x+32.6)  =180

2x = 180-32.6

x = 73.7       angle 2 = 106.3°

First write, rearrange data

Balance = $2,631

Depreciation = 2,399

Fuel = 2,108

The image of the point (1,3) after a counterclockwise rotation of 270° is (3, -1).

Every point in a figure is transformed by a rotation, which rotates each point a predetermined amount of degrees around another point.

Given that : coordinate point is (1, 3)

When rotating a figure 270 degrees counterclockwise, each point must be changed from (x, y) to (y, -x) before the rotated figure may be graphed.

So, points (1,3) changed to (3, -1).

As a result, the image of the point (1,3) following a 270° counterclockwise revolution is (3, -1).
