A sphere has a volume of 4,500 cubic feet. Find the radius of the sphere.

Answers

Step-by-step explanation:

Volume of a sphere is

[tex]v = \frac{4}{3} \times \pi \times {r}^{3} [/tex]

We are given the volume, v, and asked to find the radius, r.

Substitute 4500 ft^3 for v, solve for r.

[tex]4500 = \frac{4}{3} \times \pi \times {r}^{3} [/tex]

Multiply both sides by 3/4 to eliminate 4/3

[tex] \frac{3}{4} \times 4500 = \frac{4}{3} \times \pi \times {r}^{3} \times \frac{3}{4} [/tex]

[tex] \frac{13500}{4} = \pi \times {r}^{3} \: \\ then \: divide \: by \: \pi[/tex]

[tex] \frac{3375}{\pi} = {r}^{3 \: \: take \: the \: cubed \: root \: of \: both \: sides} [/tex]

[tex] \frac{ \sqrt[3]{ {15}^{3} } }{ \sqrt[3]{\pi} } = \sqrt[3]{r} [/tex]

[tex] \frac{15}{ \sqrt[3]{\pi} } = r [/tex]

That approximates to 10.27 ft^3

ill tell em to ya right now


Jorge’s weight change was approximately 5%.

Marie’s weight change was approximately 14%.

Marie had the greater percent change.

Jorge had the greater percent change.

Marie’s weight change was approximately 1.4%.


#edge2021

Answers

Answer:

1 ,2, and 3

Step-by-step explanation:

Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10÷190=5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175=14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.

Ali can bake 105 cookies in 3 hours. At that rate, how many cookies can she bake in 5 hours?

Answers

so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35

so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks

so 35 x 3 =105                    35 x 5=175

Ali cooks 175 cookies in 5 hours

175 cookies is the correct answer105 ÷ 3 = 3535 x 5 = 175Please let me know if I am wrong.

The price of a car is $22,000, the car is marked down $2,000, what percent is the car marked down?
(This means that the price of the car is decreasing by $2000, remember part/whole x 100)

Answers

Answer:

The car is marked down by 9.09090909 %

Step-by-step explanation:

Given

The price of car = $22,000

Markdown amount = $2,000

To determine

what percent is the car marked down

The percent of the car marked down can be determined by dividing the Markdown amount by the price of the car and multiplying the result by 100.

Markdown % = [Markdown amount / The price of car] × 100

                      =[ 2000 / 22000 ] × 100

                      = 0.0909090909  × 100

                      = 9.09090909 %

Therefore, the car is marked down by 9.09090909 %

length of edges in A: length of edges in B = 3:5
The perimeter of A is 345 mm
Work out the perimeter of B in mm.

Answer:

575 mm

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of sides.

let x be the perimeter of B then by proportion

[tex]\frac{3}{345}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )

3x = 1725 ( divide both sides by 3 )

x = 575

Then the perimeter of B is 575 mm

Answers

Answer:

g(x) = x(x - 5)(x + 4)

Step-by-step explanation:

Here the binomial is x + 4, indicating that a root is -4.  Note that x is common to all terms of g(x)=x3−x2−20x, so we can immediately write g(x) in partially factored form as

g(x) = x(x^2 - x - 20).  Since -20 = -5*4,

g(x) = x(x - 5)(x + 4)
