The ratio of boys to girls in a class is 5:3. There are 32 students in the class. How many students are boys?

Answers

Answer 1

Answer:

5x+3x=8x

8x = 32

x=32/8 = 4

boys are 4 x 5 = 20

girls are 4 x 3 = 12

Step-by-step explanation:

Answer 2

Add the ratios together: 5 + 3 = 8

Divide total students by 8:

32 / 8 = 4

Multiply each ratio by 4 to find the number of each:

Boys = 4 x 5 = 20

Girls = 3 x 4 = 12

There are 20 boys.

Solve for x.

−x − 4( 1−x)>1

x −1

x>5/3

x<−1

Answers

Answer: x>  5/3

Step-by-step explanation: Let's solve your inequality step-by-step.

−x−4(1−x)>1

Step 1: Simplify both sides of the inequality.

3x−4>1

Step 2: Add 4 to both sides.

3x−4+4>1+4

3x>5

Step 3: Divide both sides by 3.

3x /3 > 5 /3

x> 5 /3

what is the slope of a line whose equation is 2x-2y=20

Answers

Answer:

The slope is 1.

Step-by-step explanation:

To find the slope, we first have to turn this equation to the form y = mx + b.

2x - 2y = 20

Move 2x to the other side by subtracting it.

-2y = -2x + 29

Divide by -2 on both sides

y = x - 13

how do you tell if a domain is continuous or discrete on a table not a graph •~•​

Answers

Step-by-step explanation:

gegsbdqneyqillzfjmtucznYEmdnfhhthtej62wrr334tyyytyyttffgfrwgeyeyiqlstl7o4a1‍‍

9514 1404 393

Answer:

  The domain is always discrete when it is found from a table.

Step-by-step explanation:

A table necessarily lists a finite number of discrete points. The domain, as found from a table, is always discrete.

__

If the table is said to be a representation of a continuous function, then the domain of that continuous function will be continuous.

Your question seems to have to do with a table alone, not a table and an equation, or a table and a graph. A table (of points) alone cannot express a continuous domain.

__

Additional comments

One can conceive of tables that would have continuous domains, as, for example, a table with entries ...

  (x, y) = (0 ≤ x < 3, 3x+2), (3 ≤ x < 6, 4x-1), ...

Such a table is not a list of points, but is a piecewise function definition. We presume this is not what you're concerned with.

Tantasic charges a reservation fee of 20$ and $1 per minute in a tanning bed. Bettersun charges no reservation fee but charges 2$ per minute. How many minutes will the price be the same

Answers

Answer:

The indifference point is 20 minutes

Step-by-step explanation:

Giving the following information:

Tantasic:

Reservation fee of 20$ and $1 per minute

Bettersun:

2$ per minute.

First, we need to structure both total cost formulas:

Tantasic= 20 + 1x

Bettersun= 2x

x= number of minutes

Now, we equal both formulas and isolate x:

20 + 1x = 2x

20 = 1x

20= x

The indifference point is 20 minutes
