A trough is filled with water. The trough holds 315 gallons. Each cubic foot of water contains about 7.5 gallons. The trough is
elena55 [62]

Answer:

The height of the trough is about 1.5 ft

Step-by-step explanation:

If each cubic foot of water contains about 7.5 gallons.

Then; 315 gallons is about \frac{315}{7.5}=42ft^3

Let h be the height of the trough, then

7\times 4\times h=42

This implies that;

28h=42

Divide both sides by 28 to get:

h=\frac{42}{28}

\therefore h=1.5

The height of the trough is about 1.5 ft

dimulka [17.4K]
The item us going to cost 4.975
just convert the percent to decimal by moving the decimal point two spaces to the left and multiply it times the price and it will give you the discount the subtract the discount from original price and the result will be the new price.
99.50x.95=94.525
99.50- 94.55=4.975
you can round it up to 4.97

3 sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest
Naddika [18.5K]

Step-by-step explanation:

Let n be the age of the youngest sister. Since the ages are consecutive odd integers, the next sister's age is n+2, and the oldest sister is n+4. the following equation represents the relationship between the girls' ages.

n + 3(n + 4) = 5(n + 2) - 5

n + 3n + 12 = 5n + 10 - 5

4n + 12 = 5n +5

-4n  -5      -4n -5

7 = n

so the sisters are 7, 9, and 11
