Answer:

V=90

Step-by-step explanation:

<u>Step 1:  Find the volume of the cone</u>

<u />V = \frac{\pi *r^{2}*h}{3}

<u>Plug in the values</u>

<u />V = \frac{\pi *3^{2}*10}{3}

<u>Simplify and Solve</u>

<u />V = \frac{\pi *9*10}{3}

V = \frac{90\pi }{3}

V = \frac{90*3 }{3}

V=90

Answer:  V=90

Segment BDSegment BD is a perpendicular bisector of segment ACsegment AC . AD=8x−15AD=8x−15 and DC=57DC=57 .
Artist 52 [7]
Since BD is a perpendicular bisector of AC, then ADC forms an isisceles triangle with AD = DC.
Thus 8x - 15 = 57
8x = 57 + 15 = 72
x = 72/8 = 9.

The length of a rectangular prism is 1 more than three times the width w. The volume of the prism is 3 w cubed plus 19 w squared
Ket [755]

Let w represent width of the rectangle.

We have been given that the length of a rectangular prism is 1 more than three times the width w. So length of the rectangle would be 3w+1.

We have been given that the volume of the prism is 3w^3+19w^2+6w.

We know that volume of rectangular prism is width times length times height.

So we can set an equation as:

\text{Length}\times \text{Width}\times\text{Height}=3w^3+19w^2+6w

w(3w+1)\times\text{Height}=3w^3+19w^2+6w

\text{Height}=\frac{3w^3+19w^2+6w}{w(3w+1)}

Let us factor out w from numerator.

\text{Height}=\frac{w(3w^2+19w+6)}{w(3w+1)}

\text{Height}=\frac{3w^2+19w+6}{3w+1}

\text{Height}=\frac{3w^2+18w+w+6}{3w+1}

\text{Height}=\frac{3w(w+6)+1(w+6)}{3w+1}

\text{Height}=\frac{(w+6)(3w+1)}{3w+1}

Now we will cancel out (3w+1) from numerator and denominator.

\text{Height}=w+6

Therefore, the height of the prism is w+6 units.

Justin is 3 years older then Sam, and Justin’s age in 2 years will be twice what Sam’s age was 3 years ago. Find their present a
melisa1 [442]

Present age of Justin=14

Present age of Sam=11

<u>Step-by-step explanation:</u>

Let the present age of Sam=x

Given that Justin is 3 years older than Sam

present age of Justin=x+3

Age of Sam 3 years ago=x-3

Age of Justin two years hence=x+3+2=x+5

given that after 2 years Justin's age will be twice that of Sam's age three years ago

therefore

x+5=2(x-3)x+5=2x-6\\5+6=2x-x=x\\11=x

Present age of Sam=x=11

Present age of Justin=x+3=11+3=14
