Well, first I'd start off by adding the hours. 10:30 Am + 1 hour = 11:30 AM.
11:30 Am + 1 hour = 12:30 PM. 12:30 + 1 hour = 1:30 PM. Then I would add the minutes. 3/4 of an hour is 3/4 of 60 minutes which is 45 mins. So, 1:30 PM + 45 minutes would be 2:15 PM.
Answer:
your answer will be 47000
5x ÷ x² - 9 + 7 ÷ x + 3
Write the division as a fraction:
- 9 + + 3
Simplify the expression:
- 9 + + 3
Calculate the sum:
- 6 +
Write all numerators above the common denominator:
Add the numbers and you get the final answer:
Answer:
Proved
Step-by-step explanation:
Given
Prove that
Multiply the numerator and denominator by 1 + sinx
Combine both fractions to form 1
Expand the denominator using difference of two squares;
The expression becomes
From trigonometry;
The expression becomes
Divide the numerator and the denominator by cos x
Split fraction
From trigonometry;
So;
=
1sec = 3.6 x 10^5gallons
1 hr = 3600 x 3.6 x 10^5gallons
1hr = 1.296 x 10^9 gallons
