For this, you could change both the 'gallons' and the 'seconds' to get different unit with the same ratio.
1/10 gallon/second * 60 seconds / 1 minute = 6 gallons/minute
1/10 gallon/second * 1 gallon / 4 quarts = 1/40 quarts/second
combining these two conversions we can do
1/10 gallon/second * 60 second / 1 minute * 1 gallon / 4 quarts = 3/2
Final answer:
1/10 gallons/second = 6 gallons/minute = 1/40 quarts/second = 3/2 quarts/minute
Answer:
A: This quadratic expression can be factored by finding the correct pair of binomial factors
B: 4x + 5
B: 2x - 3
Step-by-step explanation:
8x² - 2x - 15 can only be factorised by finding a correct pair of binomial factors because 15 and 8 are not a perfect square.
Thus,
To find the correct pair, find the 2 numbers that would give us -120 (8*15) when multiplied, and would also give us -2 when added together.
(-12) × (+10) = -120
(-12) + (+10) = -2
-12 and +10 would be the factors to use. Thus, let's factorised as follows:
8x² - 2x - 15
8x² - 12x + 10x - 15
(8x² - 12x) + (10x - 15)
Look for common factors
4x(2x - 3) +5(2x - 3)
(4x + 5)(2x - 3)
Answer:
78.5 (please put brainliest)
Step-by-step explanation:
r = diameter / 2 = 5
area = π * r^2 = 25 * 3.14 = 78.5
Answer:
wow him idk that's pretty hard
