If he goes to bed at 9:00 pm, and wakes up at 10:00 am he will have slept 13 hours.
Answer:
21%
Step-by-step explanation:
Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.
There are 40 cats in the ecosystem.
You set 1/5 equal to x/200. Then you cross multiply the fractions to get 5x=200. You divide both terms by 5 to get x, which equals 40.
Ask which two numbers add up to -11 and multiply to 30?
That would be; -6 and -5
Rewrite the expression using what you have above;
<u>(x - 6)(x - 5)</u>
