A Job hotline service charges $25 plus a 4% commission c on the first month of earning if it finds work for a client. Write an equation that represents the total cost T to find a job through the hotline. What is the cost of a client earns $1500 the first month

Answer: 87 children and 51 adult

Step-by-step explanation:

Let x be child admission and let y be adult admission.

We know that x+y=138 based on the fact that 138 tickets were sold.

We also know that 6.3x+9.9y=1053 based on the information.

Let y=138-x

Then, 6.3x+9.9(138-x)=1053

6.3x+1366.2-9.9x=1053

-3.6x+1366.2=1053

-3.6x=-313.2

x=87

138-87=y=51

87 children's and 51 adult tickets were sold.

Dustin spends $13.6125 on going to work daily. It is 0.11 dollars per mile

Step-by-step explanation:

we have to caalculate the distance between Dustin's home and work

So

Given

Speed =s = 55 miles per hour

Time = t = 2 hours and 15 minutes

Converting time into fraction

Time = 2.25 hours

We know that

[tex]s = \frac{d}{t}\\d = s * t\\d = 55 * 2.25\\d = 123.75\ miles[/tex]

So the distance is 123.75 miles

The car travels 25 miles per gallon

We have to calculate the total number of gallon first

So,

[tex]No.\ of\ gallons = \frac{Miles}{Miles\ per\ gallon}\\=\frac{123.75}{25}\\=4.95\ gallons[/tex]

So the total amount is:

[tex]2.75*4.95\\= 13.6125\ dollars[/tex]

Total amount is $13.6125. Dividing it by total distance will give us the cost of each mile

So,[tex]Cost\ of\ mile = \frac{Total\ amount}{Distance}\\= \frac{13.6125}{123.75}\\=0.11\ dollars[/tex]

Hence,

Dustin spends $13.6125 on going to work daily. It is 0.11 dollars per mile

Answer:

m(the slope) = -2

Step-by-step explanation:

First, you want to use the slope formula. This can be written as (Y[subscript2]-Y[subscript1])/(X[subscript2]-X[subscript1]). This may seem a bit confusing but I hope it will make sense to you. The subscripts basically mean which Y value or X value you are taking. In this case, you could rewrite the equation as this: (18-8)/(1-6). The 18 is the Y value of the second point, so it is Y[subscript2]. Now all you need to do is simplify the equation.

(18-8)/(1-6)

Answer:

4/9

Step-by-step explanation:

(4/9)/(7/9) is equal to (4/9)*(9/7) because "keep change flip." So we keep the first number, change division into multiplication, and flip 4/9 (basically find the reciprocal) and that is 9/4. Thus,  (4/9)*(9/7) is equal to 4/9 because the 7's cancel.

I hope this helped!

Answer: 4/7

Step-by-step explanation: In this problem, we have 4/9 ÷ 7/9. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division to multiplication and flip the second fraction.

So here, 4/9 divided by 7/9 can be rewritten as 4/9 × 9/7.

Now we are simply multiplying fractions.

To multiply fractions, we multiply across the numerators and multiply across the denominators.

Image provided.

Notice however that 36/63 is not in lowest terms so we divide both the numerator and denominator by 9 and we get the equivalent fraction 4/7.

Therefore, 4/9 divided by 7/9 = 4/7.

Answer:

Step-by-step explanation:

The formula of a distance between two points:

We have two points (-4, -4) and (-1, 0).

Substitute:

[tex]d=\sqrt{(-1-(-4))^2+(0-(-4))^2}=\sqrt{(-1+4)^2+(0+4)^2}\\\\=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5[/tex]

Answer:

C) y+6=3/2(x-2)

Step-by-step explanation:

y-y1=m(x-x1)

m=slope & (x1, y1) is a point on the line

m=(y2-y1)/(x2-x1)

m=(-3-(-6))/(4-2)

m=(-3+6)/2

m=3/2

y-(-6)=3/2(x-2)

y+6=3/2(x-2)

Option 3

The point slope form of the given points (2, -6) and (4, -3) is [tex]y+6=\frac{3}{2}(x-2)[/tex]

Given that two points are (2, -6) and (4, -3)

We have to find the point slope form

The point-slope of the line is given as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where m is the slope of the given line.

So now to write the given points in point intercept form we need to find the slope, m

The slope of line is given as:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]\text { Here } x_{1}=2 ; y_{1}=-6 ; x_{2}=4 ; y_{2}=-3[/tex]

Plugging in the values, we get

[tex]m=\frac{-3-(-6)}{4-2}=\frac{3}{2}[/tex]

So, the slope of the given line is [tex]\frac{3}{2}[/tex]

Now, we need to find the point slope form. For that purpose we can use either of the points, but since in the answer options they have used the 1st point we will do so too.

Therefore, the point slope form is:

[tex]\begin{array}{l}{y-(-6)=\frac{3}{2}(x-2)} \\\\ {y+6=\frac{3}{2}(x-2)}\end{array}[/tex]

From the given options we can see that the correct answer is option 3.

Answer:

-12 feet per second

Step-by-step explanation:

average rate of change over [0.75, 1.25] = [tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex]

f(1.25) - f(0.75) = 4 - 10 = -6

1.25 - 0.75 = 0.5

[tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex] = [tex]\frac{-6}{0.5}[/tex] = -12

The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

We have,

To find the average rate of change of the function f(t) over the interval [0.75, 1.25], you can use the following formula:

Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)

Calculate f(1.25):

f(1.25) = -16(1.25)^2 + 20(1.25) + 4

Calculate f(0.75):

f(0.75) = -16(0.75)^2 + 20(0.75) + 4

Plug these values into the formula:

Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)

Calculate the numerator:

Average Rate of Change = [(-16(1.25)^2 + 20(1.25) + 4) - (-16(0.75)^2 + 20(0.75) + 4)] / (1.25 - 0.75)

Simplify the numerator:

Average Rate of Change = [-25 + 25 + 4 - (-9 + 15 + 4)] / (1.25 - 0.75)

Further, simplify:

Average Rate of Change = (4 - (-9 + 15 + 4)) / (1.25 - 0.75)

Continue simplifying:

Average Rate of Change = (4 - 10) / (1.25 - 0.75)

Calculate the final result:

Average Rate of Change = (-6) / (0.5)

Average Rate of Change = -12 feet per second

Thus,

The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

5 pounds of peanuts should be mixed with cashews

Step-by-step explanation:

The given is:

The price of one pound of peanut is $1.5

The price of one pound of cashew is $4.5

10-pound mixture is obtained that will sell for $3.00 per pound

We need to find how many pounds of peanuts should be mixed with cashews

Assume that x represents the number of pound of peanuts, and y represents the number of pounds of the cashews

∵ x pounds of peanuts should be mixed with y pounds of cashews

∵ The mixture obtained is 10 pounds

∴ x + y = 10 ⇒ (1)

∵ The price of each pound of peanut = $1.5

∵ The price of each pound of cashew = $4.5

∴ The selling price of the mixture = 1.5x + 4.5y

∵ The selling price of one pound of mixture = $3

∵ The mixture is 10 pounds

∴ The selling price of the mixture = 3 × 10 = 30

- Equate the two expressions of the selling price of the mixture

∴ 1.5x + 4.5y = 30 ⇒ (2)

Now we have system of equations to solve it

Multiply equation (1) by -4.5 to eliminate y

∵ -4.5x - 4.5y = -45 ⇒ (3)

- Add equations (2) and (3)

∴ -3x = -15

- Divide both sides by -3

∴ x = 5

∵ x represents the number of pounds of peanuts

∴ The number of pound of peanuts is 5

5 pounds of peanuts should be mixed with cashews

The binomial (x + 4) is not the factor of the polynomial. Then the correct option is A.

The algebraic factors with exactly two terms are known as binomial components. Although binomials are simple to solve and their roots are identical to those of polynomials, binomial factors are intriguing.

The polynomial is given below.

⇒ 4x⁴ – 21x³ – 46x² + 219x + 180

Let's check all the factors.

If the factor does not satisfy the polynomial, then the binomial is a factor of the polynomial.

For x + 4 = 0, then we have

The value of the polynomial at x = -4, will be

⇒ 4(-4)⁴ – 21(-4)³ – 46(-4)² + 219(-4) + 180

⇒ 4(256) – 21(-64) – 46(16) + 219(-4) + 180

⇒ 1024 + 1344 – 736 – 876 + 180

⇒ 2548 – 1612
