Quincy was stuck inside during an afternoon rainstorm. He spent 20 minutes reading books, 18 minutes eating lunch, 12 minutes wa
SSSSS [86.1K]

Answer:

The answer is B. He spent 3 minutes eating lunch for every 10 minutes.

Step-by-step explanation:

He spent stuck inside during the brainstorm for:

20+18+12+10= 60 minutes in total.

And now we want to know what he did for every 10 minutes he spent in the rainstorm. To do that we need to divide what he did for every 10 minutes by the total of minutes that he was stuck:

\frac{10}{60} =\frac{1}{6}

And now we can multiply the time of the activities by 1/6 to get the time he did each activity every 10 minutes.

Reading:

20*\frac{1}{6} = 3.33 minutes reading for every 10 minutes.

Eating:

18*\frac{1}{6} = 3 minutes eating for every 10 minutes.

Watching TV:

12*\frac{1}{6} = 2 minutes watching TV for every 10 minutes.

Drawing:

10*\frac{1}{6} = 1.67 minutes drawing for every 10 minutes.

Therefore he spent 3 minutes eating lunch for every 10 minutes.

Which value of x makes the equation 2/3x-3=11 true?
harkovskaia [24]

Answer:

x = 21

Step-by-step explanation:

To see for what value of x is the equation true, we have to solve x.

\displaystyle \frac{2}{3} x - 3 = 11\\\\Adding \ 3 \ to \ both \ sides\\\\\frac{2x}{3} = 11 + 3\\\\\frac{2x}{3} = 14\\\\Multiply \ 3 \ to \ both \ sides\\\\2x = 14 \times 3\\\\2x = 42 \\\\Divide\ both\ sides\ by\ 2\\\\x = 42/2\\\\x = 21\\\\For \ x = 21\ the \ given \ equation \ is \ true.\\\\\rule[225]{225}{2}

Hope this helped!

HELP PLEASE WILL MARL BRANIEST IF right
Kaylis [27]

Answer:

A bit of a doosy, but bare with me: f*g*h(x) = x^2+54x-12x\sqrt{x} -108\sqrt{x} +90

Step-by-step explanation:

So explaining this is a bit awkward as well, but I can try...So

Starting from g(x) working that backwards into f(x), so...

g(x) = x-3

f(x) = (x^4+9)

Take your g(x) and plug it into your f(x) into every x you see

f(g(x)) = (x-3)^4+9 ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...

Now you still have one more step which you still need to include h(x), so

Remember h(x) = \sqrt{x}

Now plug in your h(x) into every x you see from f(g(x)) and it should look like...

(\sqrt{x} -3)^4 + 9
