Answer:13 over 30
13/30 or 0.433
Step-by-step explanation:
Answer: $264
Steps:
1. Change 20% into a decimal. by moving decimal two places to the left.
.20
2. 330 * .20 = 66
20% of 330 is 66 meaning $66 will be discounted from the tv’s original price.
3. 330 - 66 = 264
330 - original price of tv
20% (.20) - discount
264 - price of tv after discount
Equation used to solve: 330 - (330 * .20)
Answer:
Step-by-step explanation:
2(4x - 8) - 10
8x - 16 - 10
|_______|
8x - 26
-5x + 8 - 11x - 12
___ ___ _____ ____
___ ____
-16x - 4
-3(4x - 5)
-12x + 15
For the third and first exercises, you just use the Distributive Property, and for the second exercise, all you are doing is combining like-terms.

Answer:
She should cut each diagonal piece 10 ft long.
Step-by-step explanation:
The bottom face of the box is a rectangle 8 ft by 6 ft.
A diagonal of a rectangle divides the rectangle into two congruent right triangles. With a right triangle you can use the Pythagorean theorem.
a = length of rectangle = leg of right triangle
b = width of rectangle = other leg of right triangle
c = diagonal of rectangle = hypotenuse of right triangle
a^2 + b^2 = c^2
(8 ft)^2 + (6 ft)^2 = c^2
64 ft^2 + 36 ft^2 = c^2
c^2 = 100 ft^2
Take the square root of each side.
c = 10 ft
Answer: She should cut each diagonal piece 10 ft long.
