43.75 would be the correct answer
The price before the discount was $81.00
Given;
Discounted price = $60.75
discount rate = 25%
Since the price is already discounted, it means that it is already 75% of the original price. So, we divided the discounted price by its corresponding percentage.
Original price - discount = discounted price
100% - 25% = 75%
$60.75 ÷ 75 % = $81.00
$81.00 * 25% = 20.25 discount
$81.00 - 20.25 = 60.75 discounted price
subtract 1/4 from 7/8
find common denominator, in this case 8
1/4 = 2/8
now you have 7/8 - 2/8 = 5/8 hour left
Its a function if there are different numbers as each x value but if there are multiple of the same number in the x value it isn't a function
Hello from MrBillDoesMath!
Answer:
Choice B.
Discussion:
From the first step
324 x^6 y^ 8 =
2^2 * 3^4 * x^2 * x^4* y^8
so the fourth root of this is
2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =
2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =
(2x)^(1/2) * 3 * x * y^2 =
3 * x * y^2 * sqrt(2x) =
3 * x * y^2 * ( (2x)^2) ^ (1/4)) =
3 * x * y^2 * (4x^2) ^ (1/4)
which is choice B
Thank you,
