Answer:

144π or 452.4

Step-by-step explanation:

Volume of a Sphere Formula: V = 4/3πr³

Step 1: Plug in 6 for <em>r</em>

V = 4/3π(6)³

V = 288π

Step 2: Divide by 2

V = 288π/2

V = 144π

Answer:

$515.35

Step-by-step explanation:

y-hat = 2.009x - 37.131

y-hat = 2.009(275) - 37.131

y-hat = 552.475 - 37.131

y-hat = 515.344

Therefore, the pizza parlor can expect a profit of $515.35 if it sells 275 pizzas.

Find the perimeter of the triangle in units. Round to two decimal<br> places as necessary.

Dimas [21]

Answer:

54.56 units

Step-by-step explanation:

<u>The vertices are:</u>

K(-12,2), L(-7,12), J(3,-10)

<u>Find the sides using distance formula:</u>

KL = $\sqrt{(-7+12)^2+(12-2)^2} = \sqrt{125}$ ≈ 11.18
LJ = $\sqrt{(3+7)^2+(-10-12)^2} = \sqrt{584}$ ≈ 24.17
KJ = $\sqrt{(3+12)^2+(-10-2)^2} = \sqrt{369}$ ≈ 19.21

<u>Find perimeter:</u>

P = KL + LJ + KJ
P = 11.18 + 24.17 + 19.21 = 54.56 units

If a translation take triangle CAT to C’A’T’, what is A’T’?

Nonamiya [84]

Answer:

Option (1)

Step-by-step explanation:

If a translation takes the triangle CAT to triangle C'A'T', transformation will be the rigid transformation or Isometry.

By the definition of rigid transformation, shape and size of the image and preimage remains the same.

Therefore, length of the sides of ΔC'A'T' will remain same as ΔCAT after the translation.

Option (1) √10 will be the answer.
