Mathematics

3 0

Answer:

Option A : \frac{1}{2}*14*57 is the correct answer.

Step-by-step explanation:

Given that:

Height of triangle ABC = 14 meters

Base of triangle ABC = (20 + 37) meters

Base of triangle ABC = 57 m

Area of triangle = 1/2 * Height * Base

Area of triangle = \frac{1}{2} * 14 * 57 square meters

Hence,

Option A : \frac{1}{2}*14*57 is the correct answer.

Answer:

43.4

Step-by-step explanation:

You will need to use the phythagoream therom, which is a² + b² = c².  Plug the values in for the variables to get 7² + b² = 44², (c would equal the hypothenuse because the hypothenuse is the longest side of the triangle.)  Square the values to get 49 + b² = 1936.  Subtract 49 from both sides to get b² = 1887, then take the square root of both sides to get b = 43.4 (rounded to the nearest tenth.)  

I am really sorry if I'm wrong, but have a good day/night!  :)

Kruka [31]

Answer:

3/7

Step-by-step explanation:

There are 7 letters in ALABAMA. And there are 4 A's in ALABAMA. So if you're trying to not get an A then you would subtract 4 from 7. Which you would get 3/7 of the letters in ALABAMA are not A.

mezya [45]

Answer:

8.6

Step-by-step explanation:

This uses the Pythagorean Theorem

a^2 + b^2 = c^2

a = 5

b = 7

c = ?

5^2 + 7^2 = c^2

25 + 49 = c^2

74 = c^2

sqrt(c^2) = sqrt(74)

c = 8.60 which when rounded = 8.6
