Lets name the quantity Q
Q=k* \frac{b*c}{d} 

When quantity d is tripled, we get





Q=k \frac{b*c}{3d} 

To be the relationship the same, we see that we need to 
multiply  /numerator  / by  /3 


Q =  k \frac{3bc}{3d} 

So the answer should be 
"The product of c and b must be tripled."

The measure of an exterior angle of a regular polygon is 2x and the measure of an interior angle is 4x Find the measure of one i
kolbaska11 [484]

Answer:

Part a) The measure of an exterior angle is 60°

Part b) The measure of an interior angle is 120°

Step-by-step explanation:

step 1

Find the value of x

we know that

A regular polygon has equal sides and equal interior angles

The sum of an interior angle plus an exterior angle must be equal to 180 degrees (supplementary angles)

so

2x+4x=180

solve for x

6x=180

x=30

step 2

Find the measure of an exterior angle

2x

substitute the value of x

2x=2(30)=60\°

step 3

Find the measure of an interior angle

4x

substitute the value of x

4x=4(30)=120\°

In this problem the regular polygon is a hexagon

For area A, the width will be √(3A/4), so for the three rugs, the widths are 6 ft, 9 ft, 12 ft. Corresponding lengths are 4/3 times that, so are 8 ft, 12 ft, 16 ft.

The rug dimensions are
.. 6 ft x 8 ft
.. 9 ft x 12 ft
.. 12 ft x 16 ft

Pick the one(s) that are on your list.
