You have towels of three sizes. the length of the first is 3 /4 m, which makes up 3/ 5 of the length of the second. the length of the third towel is 5 /12 of the sum of the lengths of the first two. what part of the third towel is the second?

9/10

Step-by-step explanation:

In ratio units, the relative lengths of the first, second, and third towels are ...

... 1 : 3/5 : (5/12)·(1 +3/5)

... = 1 : 3/5 : 2/3

Then the fraction the second towel is of the third towel is ...

... (3/5)/(2/3) = (3/5)·(3/2) = 9/10

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
