Cube A has a volume of 125 cubic inches. The edge lengths of cube B measure 4.8 inches. Which cube is larger and why?
Anestetic [448]

Answer: Cube A is larger. This is because volume is found by multiplying length × width × height. The length, width, and height of a cube are ALWAYS equal. Therefore if cube B has a length of 4.8 inches it also has a height of 4.8 inches and a width of 4.8 inches. To find its volume multiply 4.8×4.8×4.8 this will give you 110.592 cubic inches. This means cube A is larger.

The figure is formed from rectangles. Find the total area.
hram777 [196]

Answer:

The answer to your question is 68 ft²

Step-by-step explanation:

Data

                           Large square                Small square

base                       10 - 2 = 8 ft                       2 ft

height                         8 ft                                2 ft

Process

1.- Find the area of the large square

Area = base x height

        = 8 x 8

        = 64 ft²

2.- Find the are of the small square

Area = base x height

Area = 2 x 2

        = 4 ft²

3.- Find the total area

Total area = 64 + 4

                 = 68 ft²

Use the quadratic formula to solve the equation. -2x^2 -x+7=0
Radda [10]

Answer: x_1=1.63\\x_2=-2.13

Step-by-step explanation:

1. The quadratic formula is shown below:

x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. Given the quadratic equation given in the problem, you have that:

a=-2\\b=-1\\c=7

3. Therefore, when you substitute the values shown above, you obtain the following result:

x=\frac{-(-1)+/-\sqrt{(-1)^{2}-4(-2)(7)}}{2(-2)}

x_1=1.63\\x_2=-2.13
