<u>Answer:</u> 90%
<u>Reasoning:</u> To solve this divide 18 by 20
18/20= 0.9
Now multiply 20 by 0.9 to check
20 x 0.9= 18
Answer:
300,000 times larger than the other
Step-by-step explanation:
6×10^12 ÷ 2×10^7
6×1,000,000,000,000 ÷2×10,000,000
6,000,000,000,000 ÷ 20,000,000
300,000
<h3>There are 29 total number of questions on his math test</h3>
<em><u>Solution:</u></em>
Given that,
Amanda answered all the questions on her math test but got 10 answers wrong
She received 4 points for every correct answer, and there were no points for wrong answers
<em><u>Find the number of questions answered correctly:</u></em>
Her final score was 76 points
4 points for every correct answer
Thus,

From given.
Incorrect answers = 10
Let "x" be the total number of questions on his math test
Then,
x = correct answered questions + incorrect answered questions
x = 19 + 10
x = 29
Thus there are 29 total number of questions on his math test

false, true, true
Step-by-step explanation:
Answer:
Step-by-step explanation:
Train 1 will travel for 2 hours before the second train leaves.
<u>The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:</u>
<u>Let the trains spend x hours before crossing, then we have following equation for the distance:</u>
- x(90 + 80) = 1820
- 170x = 1820
- x = 1820/170
- x = 10 120/170 = 10 12/17 hours ≈ 10 hours and 42 minutes
<u>The trains will cross at:</u>
- 2 o'clock + 10 h 42 min = 12:42
The time when trains cross each other will be approximately 12:42
