Answer:
A and E
Step-by-step explanation:
(5n^-3)^4= A (25n^-6)^2=E
All you have to do is make and simplify a fraction. In this case, there are 6 friends going into 4 pears, so the fraction is 6/4. Then we can simplify that because they are both divisible by 2. So if we divide both by 2, our fraction becomes 3/2. Then we make that into a mixed number, with 3 going into 2 once with 1 left over. That means the answer is 1 1/2.
Answer:
Step-by-step explanation:
Multiplying bases with exponents means you have to multiply the base and add the exponent. So:
(10⁴)(5²) = 50⁶
(10³)(5³) = 50⁶
Now the equation is (50⁶/50⁶)³
Anything divided by itself will be one, so the number inside the parentheses is 1.
Now the equation is 1³, and 1x1x1 is 1.
A /b = 4 +c so the answer is 40
Answer:
135 gallons
Step-by-step explanation:
gallons of a 50% + 90 gallons of 25% = mixture that is 40%
50x + 25(90) = 40(x + 90)
50x + 2250 = 40x + 3600
10x = 1350
x = 135
