Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data;

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

[tex] V = \frac {1}{3} \pi r^{2}h[/tex]

Where;

The volume of a right circular cylinder is given by the formula;

[tex] V = \pi r^{2}h[/tex]

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

[tex] V = \frac {1}{3} \pi r^{2}h * 3[/tex]  

Substituting into the equation, we have;

[tex] V = 300 * 3[/tex]

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

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.

16. Suppose the roots are α and kα. Then we can write the equation as ...

  a(x -α)(x -kα) = 0

  ax² -ax(α +kα) +akα² = 0

Comparing to the original equation, we can equate coefficients to get ...

Solving the first for α gives ...

  α = -b/(a(1+k)

Substituting into the second, we have ...

  c = ak(-b/(a(1+k)))²

Multiplying by a(1+k)², we get ...

  (1+k)²ac = kb²

Using k=2 gives ...

  9ac = 2b² . . . . . as required

__

17. Using the previous result with k=1 (equal roots), we have ...

  (1+k)²ac = kb²

  4ac = b² . . . . . for k=1

______

Additional comment

We observed that the problems were similar, but had different factors relating the roots. So, we elected to solve the general case, then fill in the specific values for the two problems.

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:

$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

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:

A = 9/100

B = -[1/100]

C = -[39/100]

Step-by-step explanation:

Given:

0.09x - 0.01y = 0.39

Find:

A,B,C

Computation:

Linear equation;

Ax + By + C = 0

So,

0.09x - 0.01y = 0.39

9x/100 - 1y/100 = 39/100

9x/100 - 1y/100 - 39/100= 0

So,

A = 9/100

B = -[1/100]

C = -[39/100]

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:

[tex]92.9\%[/tex]

Step-by-step explanation:

Initial amount of birdseed = 10.5 pounds

Final amount of birdseed = 12 ounces

[tex]1\ \text{ounce}=\dfrac{1}{16}\ \text{pounds}[/tex]

[tex]12\ \text{ounces}=\dfrac{12}{16}=0.75\ \text{pounds}[/tex]

Percentage change in the amount of birdseed is

[tex]\dfrac{\text{Initial-Final}}{\text{Initial}}\times 100\%=\dfrac{10.5-0.75}{10.5}\times 100\%\\ =92.9\%[/tex]

The percentage of birdseed that changed is [tex]92.9\%[/tex]

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: 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.
