Answer:

I'll say 43 degrees, if you were to take out the D line, then it would've been a 180 degree, which you subtract 137 degrees from to get 43 degrees.

I think the answer is B 43

You would have to subtract 180 by 137 because the angles are supplementary to each other.

Step-by-step explanation:

n Over 54 EndFraction = StartFraction 4 Over 9 EndFraction

n/54 = 4/9

Cross product

n * 9 = 54 * 4

9n = 216

n = 216/9

n = 24

A. 24

Check:

n/54 = 4/9

24 / 54

Divide through by 6

Mango mixed 24 ounces of blue paint with 16 ounces of red paint to create a new purple color. In order to create 72 more ounces

mamaluj [8]

Answer: 28.8 ounces of red paint

Step-by-step explanation:

The total amount of paint created the first time Mango mixed colors was:

= 24 + 16

= 40 ounces of purple color

For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:

= 16/40

If one wants 72 ounces of purple therefore:

= Proportion of red used * 72 ounces

= 16/40 * 72

= 28.8 ounces of red paint

How to solve #12 can't seem to figure it out after spending 20 mins on it

The area of one of the triangular lateral faces is

$\dfrac{401.48-166.28}6=39.2$

You're told that the slant height, which is the same as the height of the triangular face, is 9.8, so you have

$39.2=\dfrac12\times9.8\times b$

where $b$ is the length of the base of the triangle, which is also the same as the side length of the base of the pyramid. So

$b=8$
