Answer:
80
Step-by-step explanation:
8 is 10% of 80 and this was 60% (logical I guess)
She took 100, the store has - 100
she went back and bough
70 bucks in stuff, the store has - 70
yes, she took the $100 bill and gave it, got back $30, that means she only kept $30 from the original bill.
the store however, lost the original $100 bill plus the $70 in merchandise, so they have -$170.
Answer:
A = 100 
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A = 
(a + b)
Now, substitute the values of the height and the bases:
A = 
(10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100

Answer: A: 3x^2y^(3/2)
Step-by-step explanation:
This can be written as
(81*x^8*y^6)^(1/4)
Then multiply each exponent by (1/4):
81^(1/4)*x^(8(1/4))y^6(1/4))
81^(1/4) = 3
x^(8(1/4)) = x^2
y^6(1/4)) = y^(3/2)
The result: 3x^2y^(3/2)
