Answer: Total class = 20 students

Step-by-step explanation: 30/6 = 5, which means that 1 student would make up 5 percent of the class.

100/5 = 20, which represents the total amount of students in that classroom because 5*20 is 100 and 5 percent represents 1 person of the class

Find the volume of the composite solid.
luda_lava [24]

Answer:

768 m^2

Step-by-step explanation:

<u>Separate the shapes</u>

We can first separate the triangular pyramid from the rectangular prism.

We can calculate them separately.

<u>Calculate</u>

The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:

8 * 8 = 64

Then we need the height which is 6 so:

64 * 6/3 = 64 * 2 = 128 m^2

Then we calculate the volum of the prism; the formula for that side times side time side:

8 * 8 * 10 = 640 m^2

The total volume is them added up:

128 + 640 = 768 m^2

Catherine paid $159.00 for an MP3 player. If the price paid includes a 6% sales tax, which of the following equations can be use
Colt1911 [192]

<u>ANSWER: </u>

The equation is y = 1.06x, so option D is correct.

<u>EXPLANATION:</u>

Given:

Amount Catherine is paid  for an MP3 player=$159.00  

The price paid includes a sales tax= 6%

To find:

Equations  that can be used to determine the price of the MP3 player before tax?

Solution:

Now, we know that, total cost = selling price of item + sales tax on item

y = x + 6% of x  

y = x +  \frac{6}{100}x

y = x + 0.06x  

y = 1.06x  

Hence, the equation is y = 1.06x, so option D is correct.

A theater contains 460 seats and the ticket prices for a recent play were $52 for adults and $26 for children. If the total proc
Vlada [557]

Answer:

The answer to your question is There were sold 166 adult tickets and 294

                                                     children tickets.

Step-by-step explanation:

Data

Total number of seats = 460

cost for adults = a = $52

cost for children = c = $26

Total cost = $16276

Process

1.- Write equations to solve this problem

              a + c = 460                    Equation l

         52a + 26c = 16276             Equation ll

2.- Solve the system of equation by substitution.

-Solve equation l for a

             a = 460 - c

-Substitute a in equation ll

         52(460 - c) + 26c = 16276

-Expand

         23920 - 52c + 26c = 16276

-Simplify

                     -26c = 16276 - 23920

                     -26c = -7644

                          c= -7644/-26

                          c = 294

3.- Find a

                        a = 460 - 294

                        a = 166
