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.

Drag each length to the correct location on the image. Each length can be used more than once, but not all lengths will be used.
Zepler [3.9K]

Applying trigonometric ratios, the missing segments lengths in the image attached below are: <em>a = 8√3; b = 12.</em>

<h3>The Trigonometric Ratios</h3>
  • SOH is sin ∅ = opp/hyp
  • CAH is cos ∅ = adj/hyp
  • TOA is tan ∅ = opp/adj
  • SOHCAHTOA is used to solve right triangles.

Given the right triangle in the mage attached below, we would find the missing sides as follows:

<em>Find a:</em>

Reference angle (∅) = 30°

opposite = 4√3

hypotenuse = a

  • <em>Apply SOH:</em>

sin 30 = (4√3)/a

a = (4√3)/sin 30

a = (4√3)/(1/2) (sin 30 = 1/2)

a = (4√3)×2

a = 8√3

<em>Find b:</em>

Reference angle (∅) = 60°

opposite = b

adjacent = 4√3

  • <em>Apply TOA:</em>

tan 60 = b/(4√3)

b = tan 60 × 4√3

b = √3 × 4√3

b = 12

Therefore, applying trigonometric ratios, the missing segments lengths in the image attached below are: <em>a = 8√3; b = 12.</em>
