Answer:

First choice: 58 seconds.

Step-by-step explanation:

27.8 is approximately 28 seconds, because 8 ≥ 5, so the number rounds up.

30.12 is approximately 30 seconds, since 1 < 5.

So, 28 + 30 is 58. Therefore, 27.8 + 30.12 ≈ 58.

horrorfan [7]

Answer:

Step-by-step explanation:

Cone

Givens

r = 1.5 inches

h = 4 inches

Formula

V = 1/3 pi r^2 h

V = 1/3 3.14 * 1.5^2 * 4

V = 1/3* 3.14 * 2.25 * 4

V = 9.42

Semi sphere

Givens

r = 1.5

Formula

V = 2/3 * pi * r^3

Solution

V = 2/3 * 3.14 * 1.^3

V = 7.065

Total

V = 9.42 + 7.065

V = 16.485

Rounded to the nearest 1/100

V = 16.49

The writing with me trying in pencil and the question is find the measure of each angle indicated
VARVARA [1.3K]

Answer:

Again every triangle is 180° and so is every straight line, so 180-105 is 75° so 75°+85° is 160 and 180-160 is 20° so your missing angle is 20°
