Arectangle has length 72 cm and width 56 cm. the other rectangle has the same area as this one, but its width is 21 cm. find the constant of variation.

A = l*w

A = 72* 56

A= 4032

4032 = L*21

4032/21 =L

L =192

scale factor:

w1/w2

56/21

divide top and bottom by 7

8/3

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
