Answer:

1. C

2. C

3. 48 in

4. C

Step-by-step explanation:

1. A perfect square is a number that can be expressed as n * n, where n is an integer. A perfect cube is a number that can be expressed as n * n * n, where n is an integer again. The three given numbers suffice both properties, hence the answer is C.

2. The volume is 9 * 9 * 9 = 729 cubic inches. We want to fit 1000 cubic inches in the box, so not everything wil fit as 729 < 1000.

3. The side lengths of the square, s, may be solved by s^2 = 144, which gives s = 12. So the perimeter is 4s = 48.

4. The area of the square is 64 square inches, so each of the side lengths measures sqrt(64) = 8 inches.

What is the length of ac <br> help pls
Lelu [443]

Answer:

x=2

Step-by-step explanation:

This is an isosceles triangle you can tell by the two congruent/equal angles

angle A is congruent/equal to angle C by definition the two sides will be equal.

x-4=3x-8

1. get all you x's on one side. by subtracting x from both sides you don't have to deal with dividing by negatives later on.

x-x-4=3x-x-8

-4=2x-8

now you want to get x by itself so add 8 to both sides

4= 2x

x is still not by itself so divide both sides by 2

x=2

Answer:

  cos(x) = 0.6

Step-by-step explanation:

First, we need to find UQ.

  UQ = UP·cos(y°) = UP·√(1 -sin²(y°)) = (26 cm)√(1 -25/169) = (26 cm)(12/13)

  UQ = 24 cm

Then TQ is ...

  TQ = 1/3UQ = 1/3(24 cm) = 8 cm

And cos(x°) is ...

  cos(x°) = √(1 -sin²(x)) = √(1 -64/100)

  cos(x°) = 6/10 = 3/5

  cos(x°) = 3/5 = 0.6
