How many hours of sleep did you get last night? What fraction of the day is that? What is the decimal equivalent (use your calculator!)? What is the percentage?

Step-by-step explanation:

I got about 9 hours of sleep last night that is 9/24 of the day or 37.5% of the day of 0.375 of the day sleeping

thanks for asking

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,
