What are the dimensions of the largest rectangular field that can be enclosed with 64m of wire?​
Natalka [10]

Step-by-step explanation:

perimeter = 2*length + 2*width

area = length*width

perimeter = 64

Rectangular means all the corners have to be right angles.

If we say it can be a square, then...

perimeter = 4*side

64 / 4 = side

side = 16 meters

So the dimensions would be 16 m x 16 m

She purchased 40% of the copies in the store. She has 80 copies of the cd. How many cd were on sale
mafiozo [28]
To find the number of CD on sale, we can set an equation.

Let y be the number if CD.

As she bought 40%, the amount she bought= 40%y

The equation:

40%y = 80

0.4y = 80

y = 80÷0.4

y=320

Therefore there were originally 320 CDs.

Hope it helps!

What is the constant of proportionality between y/x
Y_Kistochka [10]

Answer:

3.5

Step-by-step explanation:

To find the constant of proportionality between y/x you investigate the trend in values of x with corresponding values of y

For this case, when x =1, y=3.5

                       when x=2, y=7

                       

Taking in case 1, y/x = 3.5/1 = 3.5

In case 2, y/x= 7/2 = 3.5

But you know that the constant of proportionality k is given by;

y=kx------------------------making k subject of formula

y/x=k

Hence in this case, your constant of proportionality is 3.5
