Answer:

x = 25

<B = 120 degrees

<C = 30 degrees

Step-by-step explanation:

Total angle measure of a triangle - 180 degrees

Add all the angles together to find the value of x

30 + 4x + 20 + x + 5 = 180

55 + 5x = 180

55 - 55 + 5x = 180 - 55

5x = 125

$\frac{5x}{5} = \frac{125}{5}$

x = 25

<B = 4(25) + 20

<B = 100 + 20

<B = 120

<C = 25 + 5

<C = 30

in 4.5 hours, 11.25 inches of snow fell suppose the same amount of snow fell each hour how much snow fell each hour

Julli [10]

If 11.25 inches snow fell in 4.5hrs,
Then for each hr how much snow fell?

So,
4.5 : 11.25
To find how many inches that fell per hour who would need to divide the number of inches by the numbers of hours

11.25 divided by 4.5 = 2.5

So the answer would be 2.5 inch was of snow per hour

Question 1:

$7.488*10^{-8}$ ÷ $3.12*10^{2}$

= $\frac{7.488*10^{-8}}{3.12*10^{2}} = 2.4* 10^{-8-2} = 2.4* 10^{-10}$

Hence, the answer is A.

Question 2:

Mass = $2.8* 10^{-11}$ grams

New mass = $2.8 * 10^{-8}$ milligrams

Question 3:

$2.085*10^{6} = 2,085,000$

Hence, the answer is C.
