Lou has a solid clay brick in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of
Rzqust [24]

The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.

Step-by-step explanation:

The given is,

               A solid clay brick in the shape of a rectangular prism.

               A length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches.

               The clay weighs 1.055 ounces per cubic

Step:1

              Formula for volume of rectangular prism,

                                  Volume, V= whl...................(1)

            Where, w - Width of the rectangular prism

                          h - Height of rectangular prism

                           l - Length of rectangular prism

            From the given,

                         w = 3.5 inches

                          h = 2.25 inches

                           l =  8 inches

           Equation (1) becomes,

                                              = (3.5)(2.25)(8)

                                              = (7.875)(8)

                                              = 63

                            Volume, V = 63 cubic inches

Step:2

          Weight of brick = Volume of brick × Weight per cubic inch

                                     = (63) (1.055)

                                     = 66.465 ounces

          Weight of brick = 66.465 ounces

Result:

            The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.

A shirt originally cost $39.39, but it is on sale for $27.57. What is the percentage decrease of the price of the shirt?
IgorLugansk [536]

30 percent decrease

Step-by-step explanation:

looking at this i know its a percent decrease

so how do we find percent decrease ?

first we subtract the first value 39.39 & the final value 27.57

39.39-27.57 = 11.82

then we divide 11.82 by the first value

like this 11.82÷39.39 = 0.3000

then we multiply what we got by 100

0.3000×100= 30 percent

the way that most people mess up is when they divide sometimes they might do 39.39 divided by 11.82 instead of 11.82÷39.39.

For lunch with her friend, Kristionna is purchasing several side items that cost a total of $18, plus 2 sandwiches. The total co
never [62]

Answer:

C

Step-by-step explanation:

thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.

First, subtract 18 from both sides to eliminate it.

2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14

Next, separate the 2 from the x by dividing it from both sides:

2x = 14 ----> 2x/2 = 14/2 ----> x = 7

By solving this equation, we find that x, or one sandwich, costs $7.
