Answer:
50 gallons 20%
50 gallons 30%
Step-by-step explanation:
If x is gallons of 20% moonshine, and y is gallons of 30% moonshine, then:
x + y = 100
0.20x + 0.30y = 0.25(100)
Solve the system of equations using substitution or elimination. Using substitution:
0.20x + 0.30(100 − x) = 0.25(100)
0.20x + 30 − 0.30x = 25
5 = 0.10x
x = 50
y = 50
Answer: or, as a decimal, 11.7.
Step-by-Step Explanation:
1. Use the <em>distance formula</em> and substitute the values of the two ordered pairs.
...
2. <em>Multiply</em> -1 by -4.
...
3. <em>Add </em>2 and 4.
4. Raise 6 to the <em>power of 2</em>.
...
5. <em>Multiply </em>-1 by -8.
6. <em>Add</em> 2 and 8.
7. Raise 10 to the <em>power of 2</em>.
...
8. <em>Add </em>100 and 36.
9. <em>Rewrite</em> 136 as 2² · 34.
10. After factoring 4 out of 136 and rewriting as ... , <em>pull out terms from under the radical</em>. It should look like this now: . That is your final answer!!
Hope that helps! Note: the unrounded decimal is 11.66190378.

0.5 x 10^5 = 50,000
0.05 x 10^5 = 5,000
5. When you multiply by a power of 10, the decimal point moves (4) places to the (right) for every power of 10. In the expression 8.0 x 10^4, the power of 10 is (4). To multiply 8.0 x 10^4, the decimal point needs to move (4) places to the (right). The product of 8.0 x 10^4 is (80,000). Jayla is incorrect.
1/5 of the tank is filled in 1/4 of a minute.
There are 4 periods of 1/4 minute in a minute, because 4(1/4) = 1.
That means that 4(1/5) = the rate, so the rate is 4/5 of a gallon per minute.
