Person A can paint the neighbor's house 5 times as fast as Person B. The year A and B worked together, it
took them 10 days. How long would it take each to paint the house?

Answers

Answer 1

Answer:

Person A paints the house in 12 days.

person B paints the house in 60 days.

Step-by-step explanation:

The together rate is the sum of each separate rate.

Person A can paint the neighbor's house 5 times as fast as Person B.

This means that the rate of person A is 1/x, and the rate of person B is 1/5x.

The year A and B worked together, it took them 10 days.

This means that:

[tex]\frac{1}{x} + \frac{1}{5x} = \frac{1}{10}[/tex]

Multiplying everything by 10x

[tex]10 + 2 = x[/tex]

[tex]x = 12[/tex]

This means that:

Person A paints the house in 12 days.

person B paints the house in 60 days.

Step-by-step explanation:

A theater sells t tickets at a price of p dollars each. The theater conducts a survey and predicts that if the price of each ticket is changed by $2, the number of tickets sold will change by 15 tickets. If n is the number of times the theater changes the ticket price by $2, the expression (p+ 2n) (t-15n) can represent the theaters's total revenue, in dollars. In this expression, what does (t-15n) represent?

A. the number of tickets that the theater will sell If the ticket price is increased by $2

B. the number of tickets the theater will sell if the ticket prices increased by $2n

C.the number of tickets the theater will sell if the ticket price is decreased by $15​

Answers

Answer:

B

Step-by-step explanation:

You have to look at the second term to be sure of the meaning of t - 15n

What the given term says is that the total number of tickets sold (p) will decrease by 15 times the number of increases that there are.

The other term says that the cost of 1 ticket will increase that each ticket will increase by 2 dollars for each change in the ticket prices providing that change is 2 dollars.

C is out of the question. The information talks about 2 dollars per increase which is the first term.

A is not quite correct. It implies there is exactly 1 ticket increase. The crorect answer is the ticket increases can be a number of times (n)

The answer is B

How many times greater is the volume of the larger prism than the volume of the smaller one?

Answers

Answer:

8 times

Step-by-step explanation:

The volume of the prism:

V = lwh

If each of the dimensions is doubled, then the volume becomes:

V₁ = 2l*2w*2h = 8lwh = 8V

Describe an inverse function is and how they compare graphically.

Answers

The function and the inverse of the function are reflections across the line y = x. How are the graphs of a function and its inverse related? The graph of an inverse of a function f -1(x) is the reflection of the graph of the function f(x) across the line y = x.
So if you're asked to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Just look at all those values switching places from the f(x) function to its inverse g(x) (and back again), reflected over the line y = x.

Answer:

  3x -4y = 12

Step-by-step explanation:

The x- and y-intercepts are easily read from the graph as 4 and -3, respectively. Then the intercept form of the equation of the line is ...

  x/(x-intercept) +y/(y-intercept) = 1

  x/4 +y/(-3) = 1

Multiplying by 12 will clear the fractions and give the standard form:

  3x -4y = 12

A pair of shoes originally costs $60. They are on sale for 25% off and sales tax is 7%. Cost is calculated by first applying the discount, then sales tax.

What is the total cost of shoes including tax?​

Answers

Answer:

$48.15

Step-by-step explanation:

60.00 x 25% = $15.00

45.00 x 7% = $3.15

45.00 + 3.15 = $48.15
