Answer: C

The legs of the triangle are 10 and 8. You have to find the value of x.

x^2 + 8^2 = 10^2
x^2 + 64 = 100
x^2 = 36

the answer would be 6

A large rainwater collection tub is shaped like a cylinder. The diameter is 28 inches and the height is 40 inches. If the tub is

aivan3 [116]

Answer:

volume of water in the tub = 1320 inches cube

Step-by-step explanation:

The large rainwater collection tub is shaped like a cylinder. The diameter is 28 inches and the height is 40 inches .

volume of cylinder = πr²h

where

r = radius

h = height

r = diameter/2 = 28/2 = 14 inches

h = 40 inches

v = πr²h

v = 22/7 × 14 × 40

v = 12320/7

v = 1760 inches³

Volume of the large rain collector = 1760 inches³

The tub is 75 % filled .The volume of water in the tub can be computed below:

volume of water in the tub = 75/100 × 1760

volume of water in the tub = 132000 /100

volume of water in the tub = 1320 inches cube

A dump truck brought 1⁄3 of a ton of rock on the first trip, 1⁄2 of a ton on the second trip, but on the third trip, had to take

Allisa [31]

Answer:

1/30 of a ton

Step-by-step explanation:

Write this as an expression:

1/3 of a ton and 1/2 of a ton were taken to the site.

4/5 of a ton were remove from the site.

Amount of a ton at the site = $\frac{1}{3}+ \frac{1}{2}- \frac{4}{5}$

Solve the equation by finding common denominators (when the bottom numbers are the same).

$(\frac{1}{3}+ \frac{1}{2})- \frac{4}{5}$ Focus on the first part. The least common multiple (LCM) of 3 and 2 is "6", which will become the denominator.

For 1/3 to become ?/6, multiply top and bottom by 2.

For 1/2 to become ?/6, multiply top and bottom by 3.

$(\frac{2}{6}+ \frac{3}{6})- \frac{4}{5}$

Now we can add the numerators together over the same denominator.

$\frac{5}{6}- \frac{4}{5}$

Do the same thing as before and change the denominators. The LCM of 6 and 5 is "30".

For 5/6 to become ?/30, multiply top and bottom by 5.

For 4/5 to become ?/30, multiply top and bottom by 6.

$\frac{25}{30}- \frac{24}{30}$

Subtract the numerators:

$\frac{1}{30}$ Answer in tons

Therefore there was 1/30 of a ton of rock left at the construction site.
