Answer:

Cost of per session the average rate is $45.

Step-by-step explanation:

It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.

It is required to find what is the cost per session.

Step 1 of 1

It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.

To find the cost of per session calculate the average rate.

Now let $f(x)$ be the cost per session use the for the average rate of change, and the input value is the number of personal traings x.

$m=\frac{f\left(x_{2}\right)-f\left(x_{1}\right)}{x_{2}-x_{1}}$$

Now substitute, $125 for $$f\left(x_{2}\right)$ , 260 for $f\left(x_{1}\right), 2$ for $x_{1}$ and 5 for $x_{2}$ then,

$m=\frac{260-125}{5-2}$\$$\begin{aligned}&=\frac{135}{3} \\&=45\end{aligned}$$

Cost of per session the average rate is $45.

A sweater for $36 at 7% sale tax

tresset_1 [31]

$\frac{7}{100} = \frac{?}{36}$ so you cross multiply 36*7 which is 252÷100= 2.52. Then add 2.52 to 36 and your answer is 38.52

How do I simplify 7 to the power of 1

Savatey [412]

$\huge\boxed{7}$

Any number to the power of $1$ is itself. So, $7^1 = \boxed{7}$ .

Here are some more examples:

$382^1 = 382$

$0^1 = 0$

$\pi^1 = \pi$

Find the measure of each exterior angle.

devlian [24]

Answer:

The answer is 137 degrees

Step-by-step explanation:

Add up the two angles you know already

93 + 44 = 137

Then you take that number and subtract it from 180 in order to find the other interior angle.

180 - 137 = 43

So angle LKJ is 43 degree

Now to find the exterior angle you take the missing angles measurement

Which is 43 and subtract it from 180 to get 137
