Caroline cut a square cake vertically to make two rectangle slices. Each rectangle had a perimeter of 57 inches. How long is each side of the original square cake?

The length of each side is 19 inches.

Step-by-step explanation:

So the square cake is cut in half which means two half sides would equal one whole side. SO, since the two "halves" in the smaller rectangle would equal one whole side, plus the two whole sides in the smaller rectangle, you would divide 57 inches by 3.

57 divided by 3 equals the quotient of 19. Thus, the answer is 19 inches.

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
