Answer: Sara bought billboards with 4 lines for $20 (the quantity is 7)

We have to take the total cost (t) and divide that buy the 6 lines billboards and the 4 line billboards.

So, let's divide $140 by 20 and 30 (the cost for each type of billboard).

$140 ÷ 30 = 4.6

This can not be the answer because Sara bought 7 billboards, not 4.6

$140 ÷ 20 = 7

So, the answer is Sara bought billboards with 4 lines for $20.

Hope this helps you!

Answer: billboards with 4 lines for $20 (7 count)

140 divided by 30 is not 20.

140 divided by 20 is 7.

The answer to the question = 7

Answer: d) -310pi

Step-by-step explanation:

Instantaneous Rate of Change

Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.

The surface area of a cylinder of radius r and height h is:

[tex]A=2\pi r^2+2\pi r h[/tex]

We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:

The radius is r=8 mm

The height is h=3 mm

The radius changes at r'=-9 mm/hr

The height changes at h'=+2 mm/hr

Find the derivative of A with respect to time:

[tex]A'=2\pi (r^2)'+2\pi (r h)'[/tex]

[tex]A'=2\pi 2rr'+2\pi (r' h+rh')[/tex]

Substituting the values:

[tex]A'=2\pi 2(8)(-9)+2\pi ((-9) (3)+(8)(2))[/tex]

Calculating:

[tex]A'=-288\pi +2\pi (-27+16)[/tex]

[tex]A'=-288\pi +2\pi (-11)[/tex]

[tex]A'=-288\pi -22\pi[/tex]

[tex]A'=-310\pi[/tex]

Answer: d) -310pi

Answer:

Domain - [0, 4]

Range - [100, 400]

Step-by-step explanation:

Function representing the amount of money 'y' and hours of babysitting 'x' is,

y = 10x + 100

a). The dependent variable is,

   Amount of money in the bank account.

    The independent variable is,

   Number of hours of babysitting

b). x       0        1         2         3        4

    y      100    110      120     130     140

   Since, x values of a function represent the domain and y-values represent the range,

   Domain - [0, 4]

   Range - [100, 140]

Answer:

A: 20 4/5

Step-by-step explanation:

Step 6 contains an error. Option C is correct

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

The incorrect step is;

[tex]\rm 1 + cos \theta = 2 sin^2\frac{\theta}{2}[/tex]

The correct step is;

[tex]\rm 1 - cos \theta = 2 sin^2\frac{\theta}{2}[/tex]

Because when you multiply the whole equation the cosΘ will be negative and in the given solution it is positive. Step 6 contains an error.

Hence, option C is correct

The division is one of the four fundamental arithmetic operations. The time it will take both of them together to paint the house is 6.857 hours.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Let the area that is needed to be painted be x.

Given that Walter can paint the house by himself in 12 hours. Therefore, we can write the rate at which Water paint is,

Rate = Area needed to be painted / Time

       = x / 12 hours

       = x/12

Further, given that Helen can paint the house by herself in 16 hours. Therefore, we can write the rate at which Helen paint is,

Rate = Area needed to be painted / Time

       = x / 16 hours

       = x/16

Now, the rate at which they both will paint or the area that they will cover in an hour is,

Rate = (x/12) + (x/16)

       = (4x/48) + (3x/48)

       = (4x + 3x)/48

       = 7x / 48

Furthermore, the time it will take both of them together to paint the house is,

Time = Area needed to be painted / Rate

        = x / (7x/48)

        = 48/7 hours

        = 6.857 hours

Hence, the time it will take both of them together to paint the house is 6.857 hours.

Given :

Ms. Liu has $60 to buy candy and soda at the movies theatre for her family.

Candy cost $6 per box and soda cost $4 per cup.

To Find :

Write an algebraic expression that can be used to find the amount of money ms. Liu will have left if she buys a number of boxes of candy (c) and cups of soda (s).

Solution :

Let, number of candy and soda are c and s.

So, their price is :

Price = 6c + 4s

Amount left = 60 - ( 6c + 4s )

Amount left = 60 - 6c -4s

Hence, this is the required solution.

Answer:

Step-by-step explanation:

1. M is the midpoint of CD; CM = 3x - 10; MD = 6x - 22;        GIVEN

2.  CM = MD                                                                       Definition of Midpoint

3.  3x - 10 = 6x - 22                                                            Substitution Property

4.  -3x - 10 = - 22                                                      Subtraction Prop of Equality

2. Definition of a midpoint

3. Addition property of equality

To apply the addition property of equality, both sides of an equation is added with equal quantity to make it balanced.

In the two-column proof given, the missing reasons are:

Answer:

x= 175°

Step-by-step explanation:

angles in a triangle add up to 180 degrees

180 - 175 = 5 (the missing angle not x)

angles on a straight line add up to 180 degrees

Answer:

$4,022

Step-by-step explanation:

Because it is an annual salary (yearly), you would take the number and divide it by 12 (the amount of months in a year). This leaves you with $4,022

Answer:

(-1, 3), (-5, -5), and (1, 2)

Step-by-step explanation:

To make this easier to solve, simplify the inequality:

12x - 3y < 12

= -3y < -12x + 12 (subtract 12x)

= 3y > 12x - 12 (multiply by -1, switch the inequality because it was a multiplication by a negative number)

= y > 4x - 4 (divide by 3)

Now, just go through each point and see if they are correct after you plug them into the inequality and solve:

(-1, 3): 3 > -8? yes

(-5, -5): -5 > -24? yes

(0, -4): -4 > -4? no

(1, 2): 2 > 0? yes

(4, 4): 4 > 12? no

(3, 8): 8 > 8? no

In conclusion, the points (-1, 3), (-5, -5), and (1, 2) fit the inequality.

Answer: [tex]1\dfrac13[/tex] cups of pineapple juice .

Step-by-step explanation:

Equation of direct proportion between x and y:

[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

As per given,

Let x = quantity of pineapple juice and y = quantity of orange juice.

[tex]x_1=\dfrac13\[/tex]  , [tex]y_1=\dfrac34[/tex] ,  [tex]y_2=3[/tex]

Put these values in an equation we get

[tex]\dfrac{\dfrac13}{\dfrac34}=\dfrac{x_2}{3}\\\\\Rightarrow\ \dfrac{4}{9}=\dfrac{x_2}{3}\\\\\Rightarrow\ x_2=3\times\dfrac{4}{9}=\dfrac{4}{3}\\\\\Rightarrow\ x_2=1\dfrac13[/tex]

Hence, he needs [tex]1\dfrac13[/tex] cups of pineapple juice .

Answer:

He needs 1 and 1/3 cups of pinapple juice when he uses 3 cups of orange juice.
