Answer:

$170

Step-by-step explanation:

Given that:

One time fee for the use of trash dumpsters = $50

Charges for demolition per hour = $15

Time period for which trash dumpsters are used per day = 8 hours

To find:

The cost of 8 hours of operation = ?

Solution:

Here, to find the required cost, we need to first multiply the number of hours with the per hour cost of using the trash dumpsters.

And then we need to add the fixed / one time cost of the trash dumpsters to find the required cost.

Cost for using it for 8 hours = [tex]8 \times 15 = \$120[/tex]

Total cost for using it for full 8 hours = Cost for using it for 8 hours + One time cost = $120 + $50 = $170

Therefore, the answer is: $170

Answer 112.5  :)

Step-by-step explanation:

Based on the distance she was able to drive before lunch, Ashley was able to drive 112.5 miles

Ashley has a total of 200 miles to drive in order to get to her destination.

Out of that, she drove 87.5 miles and then rested. The number of miles to go is:

= Number of miles in total - Number of miles driven

= 200 - 87.5

= 112.5 miles

In conclusion, Ashley has driven 112.5 miles.

Answer: C, 3158

Step-by-step explanation:

We are given the equation [tex]h(x) = -49x-125[/tex] and we are given the hint to substitute [tex]h(-67)[/tex] into the equation. So let's do that!

[tex]h(-67) = -49(-67)-125[/tex]

we substitute -67 for the values of x.

Then, we simplify.

[tex]= 3283 - 125[/tex]

[tex]h(x) =3158[/tex]

We then subtract the numbers we multiplied together to get out answer: 3158!

Answer:

D

Step-by-step explanation:

300+50t=v

The required equation model would be 300 + 50t = v which is the correct answer would be an option (D).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The $300 football Sarah spent was autographed. The football is now worth $50 more than it was when she originally bought it which is given in the question.

Since she bought an autographed football for $300

The value of the football has increased by $50 every year

So the equation models would be as:

⇒ 300 + 50t = v

Here, v represents the value of the football, and t represents the years after she purchased it.

Hence, the correct answer would be option (D).

Answer:

20 fries per minute.

Step-by-step explanation:

If you express the number of fries per minute as 100/5 (as there are 5 minutes and 100 fries), assuming she ate at the same rate per minute, she had 20 fries per minute.

To check, multiply 20 by 5, in order to find out her fries per 5 minutes. It should be equal to 100.

Answer:

20 Fries per minute

20 fries x 1 minute = 100 fries in 5 min

Answer:

A positive slope means that something is increasing. For example if there is a positive slope in the graph of position, that means the position is increasing, or there's a positive velocity. Another example, if the graph of velocity has positive slope, it means it is increasing or there's acceleration.

Answer:

  8. 4 +2q²/p² -4r/p +r²/p²

  9. (x, y) = (3/4, -17/8)

Step-by-step explanation:

All of these questions are asking you to make use of the fact that ...

  α + β = -q/p

  αβ = r/p

__

8. (2 +α²)(2 +β²) = 4 + 2(α² +β²) +α²β²

  = 4 +2((α+β)² -2αβ) +(αβ)²

Substituting the above for the sum and product, you have ...

  = 4 + 2((-q/p)² -2(r/p)) +(r/p)²

  = 4 +2q²/p² -4r/p +r²/p²

9. This is asking for the vertex of the parabola. The x-coordinate is ...

  x=-b/(2a) = -(-3)/(2(2) = 3/4

Then the y-coordinate is ...

  y = (2(3/4) -3)(3/4) -1 = (-3/2)(3/4) -1 = -9/8 -1 = -17/8

The (x, y) values of interest are (3/4, -17/8).

Answer:

Salary = $43,313.40

Step-by-step explanation:

Let his salary be x.

Now we're told that;

Pension = 12% of his salary = 0.12x

Health Insurance = 0.3% of salary = 0.003x

Disability Insurance = 0.4% of salary = 0.004x

Since his total contract with benefits is worth $48,814.20

This means that;

x + 0.12x + 0.003x + 0.004x = 48814.2

1.127x = 48814.2

x = 48814.2/1.127

x = $43,313.40

Step-by-step explanation:

Answer: 12.5 liters of 70% hydrogen peroxide solution and 37.5 liters of 90% hydrogen peroxide solution is required.

Step-by-step explanation:

Let x = Quantity of 70% hydrogen peroxide solution.

y = Quantity of 90% hydrogen peroxide solution.

To obtain: 50 liters of a 85% solution.

x+y =50   (i)   (Total quantity of solution)

0.70x+0.50y=0.85(50)   (Total quantity of  hydrogen peroxide)

⇒ 0.70x+0.50y= 42.5 (ii)

Multiply 0.70 to (i) , we get

[tex]0.70x+0.70y=0.70(50)\\\\\Rightarrow\ 0.70x+0.70y=35\ \ \ \ (iii)[/tex]

Subtract (iii) from (ii), we get

[tex]0.20y=7.5\\\\\Rightarrow\ y=\dfrac{7.5}{0.20}\\\\\Rightarrow\ y=37.5[/tex]

Put value of y in (i) , we get

[tex]x+37.5=50\\\\\Rightarrow\ x=50-37.5\\\\\Rightarrow\ x= 12.5[/tex]

Hence, 12.5 liters of 70% hydrogen peroxide solution and 37.5 liters of 90% hydrogen peroxide solution is required.
