The relation between the numbers is 2:5 so it would be 2x and 5y and you plug in the numbers. When x=42 which is 2(21) then y would be 5(21) which equals 105 :-)
Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
Answer:
2/3 = 8/12
3/4 = 9/12
Step-by-step explanation:
whatever you do to the denominator, you have to do the the numerator.
2/3 - 3 times 4 equals 12 and 2 times 4 = 8. so 2/3 = 8/12
3/4 - 4 times 3 equals 12 and 3 times 3 equals 9. so 3/4 = 9/12
hope this helps!!!
B) side = sqrt(64)= 8, which is a rational number. Indeed, an integer. Same with perimeter: 4 times 8 = 32.
