Answer:

Yes

Step-by-step explanation:

to find area of a circle you find the radius and multiply it by itself(r^2 or r to the 2nd power) and then multiply the answer times 3.14.

(if it only shows diameter divide it by 2 and then it will be the radius)

to find circumference its 2 times radius times 3.14

The cost (c) to hire a dog trainer is varies directly with the amount of time (h) in hours spent training the dog.

NNADVOKAT [17]

Answer:

Part A) The proportional equation is $c=55h$

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

$c=kh$

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

$k=y/x$

substitute the values

$k=660/12=55$

therefore

The linear equation is

$c=55h$

For $c=\$440$

Find the value of h

substitute in the equation and solve for h

$440=55h$

$h=440/55=8\ hours$

What is the measure of the angle?

AveGali [126]

We know the full protractor measures 180 degrees.

We need to know what angle it is on. By looking at it, it looks like it is on 135.

180-135= 45

The angle is 45 <em>degrees.

I hope this helps!
