Since the equation for the volume of a pyramid is V=1/3BH you would put the answers in like this V=1/3(9)(11) which would equal V=1/3(99) which would be A. 33ft^3

Answer:

a) x = 7.5

b) x = 1

Step-by-step explanation:

a) \frac{4x - 1}{2} = x + 7

                                4x - 1 = 2(x + 7)

                                4x - 1 = 2x + 14

                             4x - 2x = 14 + 1

                                    2x = 15

                                      <u>x = 7.5</u>

b) 3x + 2 = \frac{2x + 13}{3}

3(3x + 2) = 2x + 13

   9x + 6 = 2x + 13

  9x - 2x = 13 - 6

          7x = 7

            <u>x = 1</u>

REMEMBER: When moving numbers or symbols from one side of an equation to another, you must reverse the mathematical function (e.g. × becomes a ÷, and + becomes a -). A fraction is always a ÷, so when you move the denominator (bottom number), it becomes a ×.

What happens to the surface area of a rectangular prism when each of the dimensions is doubled? (1 point) i?
photoshop1234 [79]
The surface area will be 4 times the original size. Here is why: You are doubling each dimension, and area is a 2 dimensional measurement. Because of this whatever you are doing to the length of the side will happen 2 times. In this case it would be x2 x2 which equals 4. You can provide evident by using a cube. The surface area of a cube with side lengths of 1 would be 1 x 6=6 square inches. If you double the side length, it would be 4 x 6= 24 square inches.

The circle given by x^2+y^2-6y-12=0 can be written in standard form like this: x^2+(y-k)^2=21 What is the value of k in this equ
sweet [91]

Answer:

The value of k =3

Step-by-step explanation:

x^2+y^2-6y-12=0 We need to solve this equation to become in standard form to find the value of k.

x^2+y^2-6y-12=0\\x^2+y^2-6y = 12\\(x)^2 +(y^2-2(y)(3)+(3)^2) = 12 +(3)^2\\(x)^2+(y-3)^2 = 12+9\\(x)^2 +(y-3)^2 = 21

The given standard form is:

x^2+(y-k)^2=21

Comparing it with (x)^2 +(y-3)^2 = 21

The value of k =3
