In 1970, a record 1.5 inches of rain fell in one minute at Brasse Terre, Guadalupe in the Caribbean. At this rate how much rain fell in 3 seconds or 0.05 of a minute? A 3 inches... B 0.075 inch... C 0.75 inch... D 30 inch. Pick one. Evan chose D as the correct answer. How did he get that answer?
Answer:
Option B is correct.
Step-by-step explanation:
Given.
The rain fall rate is 1.5 inches per minute.
How much rain fall in 3 second or 0.05 of minute?
First we find rain fall rate in one second.
So, 0.025 inches of rain fall in one second.
Therefore, the rain fall in 3 second is
The rain fall in 3 second is 0.075 inches.
If you chose option D is correct
If the rain fall is continue to 20 min at the rate of 1.5 inches per min, then the rain fall will be 30 inches.
The rain fall in 3 second is 0.075 inches.

4) x = 10
Step-by-step explanation:
The formula for finding the sum of interior angles in a polygon is the following,
Where (S) represents the sum of interior angles, and (n) represents the number of sides.
1)
The given polygon is a hexagon, meaning it has (6) sides. Substitute the number of sides into the formula and solve for the sum of interior angles.
2)
This polygon is a pentagon, meaning it has (5) sides. Substitute the number of sides into the formula and solve for the sum of interior angles.
3)
The sum of interior angles in a triangle is (180) degrees. One can see that one of the measures of an angle is (90) degrees (indicated by the box around the angle). One can form an equation by adding up the expressions for the angle measures and setting it equal to (180) degrees.
(55) + (x + 36) + (90) = 180
Simplify,
181 + x = 180
Inverse operations,
181 + x = 180
x = -1
4)
The remote angles theorem states that when one extends one of the sides of a triangle, the angle formed between the side and the extension is equal to the sum of the two non-adjacent interior angles in the triangle. Based on this theorem, one can form an equation and solve for the unknown.
<F + <G = <FEZ
Substitute,
(4x) + (-5 + 7x) = 105
Simplify,
4x - 5 + 7x = 105
11x - 5 = 105
Inverse operations,
11x - 5 = 105
11x = 110
x = 10
