At the theater, one section of seats has 8 rows with 12 seats in each row. In the center of each of the first 3 rows are 4 broken seats that cannot be used. How many seats can be used in the section?

Answers

Answer 1
Answer: 92 because 8*12 is 96. Then, you have to do 96 - 4 which is 92.
Answer 2
Answer:

Final answer:

Initially, we have 96 seats in the theater. However, due to 12 broken seats in the first 3 rows, 84 seats are usable.

Explanation:

To answer this question, we will use simple multiplication and subtraction techniques of Mathematics. This is about calculating the number of workable seats in a theater.

First, we need to calculate the total number of seats in the theater. There are 8 rows with 12 seats in each row. We multiply the number of rows by the number of seats in each row: 8 rows * 12 seats/row = 96 seats.

In the first 3 rows, there are 4 broken seats in each of these rows. We need to subtract these from the total number of seats: 3 rows * 4 broken seats/row = 12 broken seats.

Finally, we subtract the number of broken seats from the total number of seats to find out how many seats can be used: 96 seats - 12 broken seats = 84 usable seats.

Answers

Answer:

c. 8×4-(2×3+8)÷2

Step-by-step explanation:

Using the rules of BODMAS,

B stands for  bracket

O stands for Order

D stands  for Division

M stands for Multiplication

A stands for Addition

S stands for Subtraction

8×4-(2×3+8)÷2

Now using this rule we will first of all open the bracket, In the bracket we multiply then add

8 × 4 - (6 +8) ÷ 2

8 × 4 - 14 ÷ 2

Still applying the rule, we divide 14 by 2 to give us 7

8 × 4  - 7

Then, still applying the rule, we multiply 8 by 4 which will give us 32

32 - 7

Then we finally subtract 7 from 32 to give us 25

32 - 7 = 25

So the expression;  8×4-(2×3+8)÷2    is equivalent to 25

The answer is C.

Proof:
8×4-(2×3+8)÷2
=32-(6+8)÷2
=32-14÷2
=32-7
=25

Name1. Emerson is starting a new business. Product Acosts her $26.50. She decides to mark theproduct up 30%. How will Emerson charge forProduct A

Answers

The markup price at which Emerson is selling is $34.45.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Emerson is starting a new business. The product costs her $26.50.

She decides to mark the product up 30%.

∴ Her markup price will be 130% of $26.50, which is,

= (130/100)×$26.50.

= $34.45

Write the slope intercept form of the equation of the line through the given points and slope 1,1 and slope of -3/5

Answers

Slope is already given in the question so we only need to solve for the y-intercept.

Slope intercept form: y = mx + b

m = slope

b = y-intercept

-3/5 = -0.6

1 = -0.6(1) + b

1 = -0.6 + b

1 + 0.6 = -0.6 + b + 0.6

1.6 = b

Now, write in slope-intercept form.

y = -3/5x - 1.6

Answers

x=total number of students.
80% of x=20
Therefore, the equaciton can be used to find the total number of students, in the math class is:
(80/100)x=20

We can solve this equation:
(80/100)x=20
x=(20*100)/80=25

Answer: the equation is (80/100)x=20 and its solutions is 25 students.
