Answer:49

Step-by-step explanation:42/6=7, this means he did the original run 7 times, so you would multiply the miles by 7 too, and you get 49

49 because 42 / 6 = 7 and 7 x 7 = 49

Suppose the population of a town is 2,700 and is growing 4% each year. Write an equation to model the population growth. Predict

100% = 2700
4% = 4/100 x 2700/1
4% = 108
108 x 12 = 1296
1296 + 2700 = 3996

Find the area of a square whose diagonal length is 32 CM

BigorU [14]

Answer:

512cm^2

Step-by-step explanation:

Let's imagine cutting the square down that diagonal. Now, we have two isosceles right triangles with a hypotenuse with length 32cm. Let's take one of those triangles for now and focus on it. Let's give the one of the legs of a triangle some length x. Since both legs are the same length, by the Pythagorean theorem:

$x^2+x^2=32^2\\\\2x^2=1024\\\\x^2=512\\\\x=\sqrt{512}$

Since this leg makes up one side of the square, we can use it to calculate the area of the square, which is just the side length squared:

$A=(\sqrt{512})^2 = 512$

Answer:

(A) 24 and 66

Step-by-step explanation

Complementary angles add up to 90 degrees

Supplementary angles add up to 180 degrees

(A) 24 + 60 = 90

These 2 angles sum to 90, so therefore they are complementary

(B) 56 + 124 = 180

These 2 angles sum to 180, so they are supplementary, not complementary

While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question

(D) 56 + 124 = 180; 66 + 114 = 180

Both of these angle pairs are supplementary, so they do not satisfy the answer to the question
