Answer:

Step-by-step explanation:

For x use the Pythagorean theorem:

$x^2+6^2=10^2$

$x^2+36=100$ subtract 36 from both sides

$x^2=64\to x=\sqrt{64}\\\\x=8$

We know: x + y = 20. Substitute:

$8+y=20$ subtract 8 from both sides

$y=12$

12) Oliver is not allowed to watch more than 4 hours of television a week. He watched his favorite show on Monday which was 1 ho

Semenov [28]

Answer:

B. Oliver can watch TV for 1.5 hours more this week.

Step-by-step explanation:

Oliver is not allowed to watch more than 4 hours of television a week. He watched his favorite show on Monday which was 1 hour long and his favorite Tuesday show which was 1.5 hours long.

So he has already finished 2.5 hours of watching . He can watch only for 4 hours for the total week.

Let x be the number of more hours for which he can watch television.

Then ,

x + 1 + 1.5 = 4

x + 2.5 = 4

x = 4 - 2.5

x = 1.5 hours.

So Oliver can watch television for at most 1.5 hours for the rest of the week.

Then the correct option is B.

Winnie poured 14 cups of water into a rectangular container measuring 13 inches by 7 inches by 6 centimeters.

kow [346]

Max volume = Volume of container = 13 in x 7 in x 6 in = 546 in^3
Part B: 
1 cup = 14.4375 in^3 
14 cups = 14.4375 in^3 * 7 = 202.125 in^3 
Part C: 
Height of water = (202.125 in^3)/(13 in x 7 in) = 2.22 in.

A landscaper has 10 2/5 cubic yards of peat moss in a truck. If he unloads 2 2/3 cubic yards at the first site and 2 1/4 cubic y

Vikentia [17]

Step-by-step explanation:

The problem bothers on fractions, here we are being presented with mixed fractions.

what we are going to do bascially is to subtract the sum of all the uloaded

peat moss in sites 1 and 2 to get from the peat moss to get the remaining for the third site

therefore

$10\frac{2}{5}-(2\frac{2}{3}+ 2\frac{1}{4})$

we then have to convert the mixed fraction to further simplify the problem we have

$\frac{52}{5}-(\frac{8}{3}+ \frac{9}{4})$

we then solve the fraction to the right of the negative symbol first

$=\frac{52}{5}-(\frac{8}{3}+ \frac{9}{4})\\\\=\frac{52}{5}-\frac{32+27}{12} \\\\=\frac{52}{5}-\frac{59}{12} \\\\\=\frac{624-295}{60} \\\\=\frac{329}{60}$
