Answer:

The length of rectangle is 6 units and the width is 1.5 units

Step-by-step explanation:

Let

L -----> the length of rectangle

W ----> the width of rectangle

we know that

The area of rectangle is equal to

A=LW

we have

A=9\ units^{2}

so

9=LW -----> equation A

A rectangle width is one fourth it’s length

so

W=\frac{1}{4}L ----> equation B

substitute equation B in equation A and solve for L

9=L(\frac{1}{4}L)

L^{2}=9*4

L^{2}=36

take square root both sides

L=6\ units

Find the value of W

W=\frac{1}{4}(6)

W=1.5\ units

There are 80 members of the show choir. For a fund raiser 95% of the members raised money, how many members did NOT raise money.
Mumz [18]
To find out how many did not raise money, we need to find the percentage that did not raise money and multiply that by the total number of members.

If 95% raised money, 5% did not raise money.

0.05 x 80 = 4 members did not raise money
