A town in east Texas recieved 10 inches of rain in two weeks. If it kept raining at this rate for a 31-day month, how much rain did the town recieve?

Answers

Answer 1
Answer: The best way to approach this problem is to find out how much fell in week. As you know what two weeks is, you simply have to halve this, giving you that one week is 5 inches of rain. One you have this, you can multiply this by 4 (as this will give you 4 weeks, or 28 days), and this gives you 20 inches in 28 days. You should then find the odd three days. If you divide 5 by 7, this will give you the rain fall in one day. 5/7= 0.8 inches per day. You then have top multiply this by 3 (as you've got three odd days), and this gives you 2.4. You then have to add together 2.4 and 20, giving you 22.4
Therefore, if the rain continued to fall at the same rate for 31 days, it would receive 22.4 inches of rain.
Hope this helps :)

Answers

Hi CuteFace ! Estimating is an easier way to find out an answer ! To estimate this particular problem you have to round both the numbers so 4.23 would round to 4 and 2.51 would round to 3 . 4-3=1

Answer:

If you round it would be 4-3=? . If the decimal is above .50 then you would go up one number in the ones place if it is not then it stays the same.

Is my answer right.

Answer:

Yes

Step-by-step explanation:

The two angles that are both acute (B and C in this case) add up to 90 degrees. That's because a right triangle has 1 angle that = 90 and every triangle has 180 degrees.

<B + <C + 90 = 180

<B + <C = 180 - 90

<B + <C = 90

Equation

2x + 15 + 5x - 2 = 90       Collect like terms

Solution

7x + 13 = 90                      Subtract 13 from both sides

7x = 90 - 13                       Subtract

7x = 77                               Divide by 7

x = 77/7                              Divide

x = 11                                  Substitute

<B

<B  = 2x + 15

<B = 2*11 + 15

<B = 37  which makes your answer right

B. Is correct


37°
