Answer:
≈9.64 gallons
Step-by-step explanation:
To solve, we can figure out how many quarts are in a minute and use that to figure out how many quarts are in an hour. Then, we can convert quarts to gallons.
4.5 quarts = 7 minutes
First, we can find how many quarts equal 1 minute. To do this, we can divide both sides by 7 because anything divided by itself equals 1
4.5/7 quarts = 1 minute
Next, we want to figure out how many quarts go into 60 minutes, or 1 hour. To do this, we can multiply both sides by 60 because 1 * 60 = 60
4.5 * 60 / 7 quarts = 60 minutes = 1 hour
We now know how many quarts are in an hour, so we can now convert quarts to gallons
4 quarts = 1 gallon
divide both sides by 4
1 quart = 1/4 gallons
To get from quarts to gallons, we can divide by 4, so we have
(4.5 * 60 / 7)/4 = 4.5 * 60 / 28
≈9.64 gallons
6 = 3(x - 2)
6 = 3x - 6
3x = 12, x = 4
Solution: D
Answer:
x = 6.6
Step-by-step explanation:
law of cosines:
x² = b² + c² - 2ac · cosX
x² = 5² + 8² - 2(5 · 8) · cos 55°
x² = 25 + 64 - 80· cos 55°
x² = 25 + 64 - 45.89
x² = 89 - 45.89
x² = 43.11
x = √43.11
x ≈ 6.6
