So let's begin!
So the length is 25 and the entire perimeter is 106. Lets put these both of these numbers as information we know.

We know the length is 25.
We know the full perimeter is 106.
We also know a rectangle has 2 pairs of congruent sides.

Okay so, the length is 25.
Since there are two sides that are the same we would multiply 25 by 2 to get 50.

Now we know 2 sides out of the four sides on a rectangle.

106 is the final perimeter, if we subtract 50 from 106, we get 56. That is the measurement for both sides we're missing but we need to know the width for just one side.
So we divide 56 by 2 to get 28.
The width is 28.

Heres the show your work part:

25 x 2 = 50
Gets both lengths for rectangle.

106 - 50 = 56
Gets the product for the widths.

56 / 2 = 28
Gets the width of just one side.

Your final answer: 28

A) The equation of the line is: $y-1250=35(x-30)$

B) The slope is the amount of money earned for one hour of work

Step-by-step explanation:

In order to find the linear function that models the relationship between the number of hours worked and the money earned, we need to find the slope of the function.

Here we have:

Number of hours worked = x = independent variable

Money earned = y = dependent variable

Therefore, the slope can be found as

$m=\frac{y_2-y_1}{x_2-x_1}$

where:

$x_1 = 30 h$

$y_1 = 1250$ is the money earned when x = 30 h

$x_2 = 55 h$

$y_2 = 2125$ is the money earned when x = 55 h

Substituting,

$m=\frac{2125-1250}{55-30}=35$

Now we can find the equation of the line using:

$y-y_1 = m(x-x_1)$

And susbtituting,

$y-1250=35(x-30)$

In part A, we found that the slope of the line is

m = 35 $/h

The slope of the line represents the rate of increase of the dependent variable (the money) with respect to the rate of increase of the independent variable (the number of hours worked).

In other words, the slope of the line represents the amount of money earned by a worker during one hour of work. So, this means that if the technician works 1 hour, he earns 35$; if he works 2 hours, he earns 70$; and so on.

Determine the measurement of angle 2<br> i need all angles from 2 to 8

SOVA2 [1]

Answer:

<1 = 112º

<2 = 68º (given)

<3 = 68º

<4 = 112º

<5 = 112º

<6 = 68º

<7 = 68º

<8 = 112º

Step-by-step explanation:

Supplementary angles add up to 180º. Once you find the measure of <1 and <2, the bigger angle will always be the bigger number and the smaller angle will always be the smaller number from <1 and <2.

There's a better way to explain it but you would need to go to the basics of all angle rules.

10 coupons are given to 20 shoppers in a store. Each shopper can receive at most one coupon. 5 of the shoppers are women and 15

Alina [70]

Answer:

$\, {20 \choose 10} - {15 \choose 10}$

Step-by-step explanation:

We can find the total amount of ways at least a woman receives a coupon by calculating the total amount of possibilities ot distribute the coupon and substract it to the total amount of possibilities to distribute 10 coupons to the 15 men (this is the complementary case that at least a woman receives a cupon).

- The total amount of possibilities to distribute the coupons among the 20 shoppers is equivalent to the total amount of ways to pick a subset of 10 elements from a set of 20. This is the combinatiorial number of 20 with 10, in other words, $\, {20 \choose 10} = \frac{20!}{10!10!} .$

- To calculate the total amount of possibilities to distribute the coupons among the 15 men, we need to make the same computation we made above but with a set of 15 elements instead of 20. This gives us $\, {15 \choose 10} = \frac{15!}{10!5!}$ possibilities.

Therefore, we have $\, {20 \choose 10} - {15 \choose 10}$ possibilities to distribute the coupons so that at least one woman receives a coupon.

I hope that works for you!
