How does finding the unit rate make it easier to solve problems?

Answer:

k = -13

Step-by-step explanation:

-4(k +2) = -k +31

you multiply the bracket by -4

-4k-8 = -k+31

Collect the like terms

-4k+k = 31+8

-3k =39

divide both sides by -3

k = -13

Answer:

k = -13

Step-by-step explanation:

Distributive property

(-4 x k + -4 x 2)

-4k + -8 = -k + 31

subtract 31 from both sides.

-4k - 39 = -k

add 4k to both sides

-39 = 3k

divide 3 from both sides

-13 = k

Answer:

180mm^2

Step-by-step explanation:

CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm

CB is 16mm

the area of the triangle is A=ab/2

A=45mm^2

Now you need to find the area of the rectangle

A=l×w

A= 15×9= 135mm^2

now add both areas

(135+45)mm^2=180mm^2

Answer:

2/3w = 84

w = 126 ft.

Answer:

Step-by-step explanation:

A=LW

W=A/L

We are given A=84 and L=2/3 so

W=84/(2/3)

W=84(3/2)

W=126 ft

Answer:

Step-by-step explanation:

1/2 * 1/2 * 1/2 * 1/2 = [tex](\frac{1}{2})^{4}[/tex]

[tex]\frac{1}{a^{m}}= a^{-m}[/tex]

[tex](\frac{1}{2})^{4} = 2^{-4}[/tex]

Answer:

C

Step-by-step explanation:

The x is 3 and the y is 1 so if you divide the x by 3 it is 1 which is the y.

The relationships which have the same constant of proportionality between y and x as in the equation y = 1/3x are C and E.

The slope of a line is the ratio that determines the steepness as well as the direction of the line.

Let the two points on a line be [tex](x_{1} , y_{1} )[/tex] and [tex](x_{2} , y_{2 )[/tex]. The slope can be found as follows:

[tex]\frac{(y_{2} -y_{1} )}{(x_{2} -x_{1} )}[/tex]

The constant of proportionality in the given problem can be understood as the slope of the line. Thus the lines with their slopes as 1/3 will have the same constant of proportionality as the equation y = 1/3 x.

We can observe the graphs given and find their respective slopes. It can be done as follows:

(3 - 0)/(0 + 3) = 1

(3 - 0)/(1 - 0) = 3

(1 - 0)/(3 - 0) = 1/3

(29.1 - 4.8)/(9.7 - 1..6) = 3.111

(0.8 - 0.5)/(2.4 - 1.5) = 1/3

Therefore, graphs C and E have relationships that have the same constant of proportionality between y and x as in the equation y = 1/3 x.

Step-by-step explanation:

The solution is : 6 feet describes the center, and 9 feet describes the spread

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

here, we have,

The center of a data set is mostly considered as the median or the mean

Here mean is 6 (given). And median is also 6.

As 6 is exactly at the middle of the data set. (When arranged in ascending order)

Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.

Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.

Answer:

18 inch

Step-by-step explanation:

In a full rotation, a wheel covers its full perimeter(circumference). Let the diameter be d.

=> circumference = 57 inch

=> πd = 57 inch

=> (22/7) d = 57 inch.

=> d = (57 * 7)/22 inch

=> d ≈ 18.13 inch

=> d = 18 inch (nearest inch)
