Step-by-step explanation:

A concert promoter charges $65 per ticket for a concert. The promoter's cost will be $5500 plus $4 per ticket.

If r = revenue and n = number of tickets sold, then r(n) shows how revenue (amount of money received from ticket sales) depends on the number of tickets sold.

r(n) = 65n

If c = cost and n = number of tickets sold, then c(n) shows how cost (expenses of the concert promoter) depends on the number of tickets sold.

c(n) = 4n + 5500

Answers

Answer:

here you go mate

you would just plug in the formulas given to you following the hint it's:

r(n) - c(n)

which goes to

65n - (4n + 5500)

then we can simplify that to  

61n - 5500

Part 2:

61(850) - 5500

51850 - 5500 = 46350

this means if he sells 850 tickets he will make a net of 46350 dollars

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
А. 12 inches
B. 15 inches
C. 21 inches
D.40 inches​

Answers

the answer would be B. 15 inches
Given :-

The perimeter of a rectangle is 42 inches. The width of the rectangle is 6 inches.

To Find :-

The length

Solution :-

We know that,

Perimeter of a Rectangle = 2 (length + width)

Hence,

42 = 2 (length + 6)

or, 42/2 = length + 6

or, 21 = length + 6

or, length = 21 - 6

or, length = 15

The length is 15 inches.

Therefore, the correct answer is option (B) 15 inches.

Answers

Answer:

$3.21

Step-by-step explanation:

Answer:

1: $3.21.

2: 50x+120=300

3: h=5/7/ first step would be to adding 7 to both sides.

Step-by-step explanation:

for the 3rd:

you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.

Answers

Answer:

Answer is F:
 y = 2x + 4

Step-by-step explanation:

The slope-intercept form of a line is given by
y = mx + b

where m is the slope of the line and b is the y-intercept ie the y value where the line crosses the y axis for x = 0

In the line y = 2x + 4, the slope of the line is 2

If 2 lines are parallel to each other, they must have the same slope

Therefore the line passing through (-1,2) must have an equation of the form y = 2x + b.

There are only 2 choices that fit this equation, F and H

If we substitute the values of x=-1  into the F equation for testing we get

y = 2(-1) + 4 = -2 +4 = 2 which is the correct value for y for the point(-1,2)

The other choice y = 2x + 3 does not work because substituting for x we get

y = 2(-1) + 3 = -2 + 3 = 1 which is not the value of y for the point (-1,2)

Answer:-125/21 or -5 20/21


Steps:

First, change the mixed numbers to improper fractions.

So -3 2/7 = -23/7
2 2/3= 8/3

Second, make the denominators the same number

So multiply -23/7 by 3 and 8/3 by 7

-69/21-56/21

Subtract the numerators

-69-56= -125

So the answer is -125/21 or -5 20/21

The figure below shows a rectangular prism and a cube:

A rectangular prism and a cube are drawn side by side. The length of the rectangle prism is 5 inches, the width is 4 over 5 inch, and its height is 1 and 3 over 5 inches. The cube has a side length of 1 over 5 inch.

How many such cubes are required to completely pack the prism without any gap or overlap?

Answers

Answer:

Calculate the volume of each shape.

Volume of rectangle = 6 x 5/6 x 1 2/6 = 6 2/3 cubic inches.

Volume of cube = 1/6 x 1/6 x 1/6 = 1/216 cubic inch.

Now divide the volume of the rectangle by the volume of the cube:

6 2/3 / 1/216 = 1440

It will take 1.440 cubes to fill the rectangle.
