The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.
Answer:
314.2 cm^2
Step-by-step explanation:
The formula for the area of a circle of radius r is A = 3.14r^2.
With r = 10 cm, r^2 = 100 cm^2, and so the area of this circle is 314.2 cm^2, to the nearest tenth.
The missing numbers for distance are 9 and 20
The missing numbers for time are 12 and 48

A, B, D
A: because there are two colour types in a deck of cards, so it’s 1/2 probability of getting a black one.
B: because there a four suits in a deck of cards, so the probability of getting a diamond is 1/4
D: because when calculating compound events we multiply the two probabilities,
so 1/2 x 1/4 = 1/8
14:35 is a ratio, and of-coarse, as we know, we can transform that into another way of writing a ratio:
14/35
Simplify
14/7 = 2
35/7 = 5
2:5
Answer: 2 to 5
