Explain how you find m∠3 if m∠5 = 130° and m∠4 = 70°. *

Answers

Answer 1
Answer:

Answer:

The required measure of angle 3 is 60°.

Step-by-step explanation:

 We are given to find the measure of angle 3 from the figure if

m∠5 = 130° and m∠4 = 70°.

Let the measure of angle 3 be x°.

From the figure, we note that

angle 5 is an exterior angle and angles 3 and 4 are two remote interior angles of the triangle.

We know that

the measure of an exterior angle to a triangle is equal to the sum of the measures of two remote interior angles.

So, we get

Thus, the required measure of angle 3 is 60°.

Last week it snowed 4.32 inches on Monday and 6.86 inches on Tuesday. It snowed 7.89 inches this week. Round each number to the nearest tenth.

About how much more did it snow last week than this week?

A.
about 4.0 inches

B.
about 3.5 inches

C.
about 3.3 inches

D.
about 3.2 inches

Answers

3.29 but when it gets rounded, it is c. 3.3 inches

Final answer:

Rounding the snowfall from last week and this week to the nearest tenth results in a total of 11.2 inches last week and 7.9 inches this week. The difference, or how much more it snowed last week than this week, is 3.3 inches.

Explanation:

Last week, it snowed 4.32 inches on Monday and 6.86 inches on Tuesday. When you round these to the nearest tenth, they become 4.3 inches and 6.9 inches respectively. Therefore, the total snowfall last week was 4.3 inches + 6.9 inches = 11.2 inches.

This week it snowed 7.89 inches. When we round it to the nearest tenth, it becomes 7.9 inches.

Now to figure out how much more it snowed last week than this week, we subtract the snowfall of this week from the total snowfall of last week, which is 11.2 inches - 7.9 inches = 3.3 inches. So, it snowed about 3.3 inches more last week than this week.

1.) C - The solution is also -12 because negatives multiplied by negatives cancel each other out. 
2.) D - What you did was you chose the answer that looked like where C is. Notice how there is a square root symbol next to the numbers. 
4.) C - The square root is 8.3666002534... It would round to 8 and 9.
7.) A - 5 to the third power is 125. (5 x 5 x 5 = 125)
