Answer:

∠ 2 = 160°

Step-by-step explanation:

1 and 2 are adjacent angles and are supplementary, thus

1 + 2 = 180° , that is

20° + 2 = 180° ( subtract 20° from both sides )

A = 160°

The volume of a cube of ice for an ice sculpture is 64,000 cubic inches.

Montano1993 [528]

A) To find the edge length from the volume you use the formula:

e = V¹ˡ³ (to the power of 1/3) where e is the edge length.

Substitute in the volume:

e = 64000¹ˡ³

Solve:

Edge length = 40 inches

b) To find the surface area from the volume you use the formula:

s = 6V²ˡ³ (to the power of 2/3) where s is the surface area.

Substitute in the volume:

s = 6 x 64000²ˡ³

Solve:

s = 384000²ˡ³

Surface area = 9600 square inches

What is the probability that when a pair of dice is rolled, at least one die shows a 3 or the dice sum to 8?

amm1812

Given condition is that two die are rolled together. So there are 36 combinations of two rolled dice. And the following have a sum of 8 : 2–6, 3–5, 4–4, 5–3 and 6–2. Out of these five combinations, 2 show the number 3.

So probability(sum is 8) becomes = $\frac{5}{36}$
