PLEASE HELP!!!!!!!!!

Answer:

V = pi*r^2*h

V = 150 m^3

h = 8 m

150 = pi*r^2*8

Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.

V = 1/3 pi r^2 h

Diameter of the cone is 15 m. So, option D is correct.

Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.

Here,

Volume of the cone is given by,

 V = 150[tex]\pi[/tex] m³

Height of the cone, h = 8 m

We know, the equation for the volume of a cone is,

V = 1/3[tex]\pi[/tex]r²h

where r is the radius and h is the height of the cone.

So,

(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]

r²x 8 = 3 x 150 = 450

r² = 450/8

r² = 56.25

r = 7.5 m

Therefore, diameter of the cone,

d = 2r

d = 2 x 7.5

d = 15 m

Hence,

Diameter of the cone is 15 m.

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

---------------------------

       23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

5x+2y =19

Substitute y=2

5x+2(2) =19

5x+4 = 19

Subtract 4 from each side

5x +4-4 =19-4

5x= 15

Divide by 5

5x/5 = 15/5

x=3

The solution is

Answer:

(-4,1.5)

Step-by-step explanation:

Given :-

And we need to find out the midpoint of the two points. The midpoint of two points is given by the ,

[tex]:\implies[/tex] Midpoint =( x1+x2/2 , y1+y2/2)

[tex]:\implies[/tex] Midpoint =( -5-3/2 , 5-2/2)

[tex]:\implies[/tex] Midpoint =(-8/2,3/2)

[tex]:\implies[/tex] Midpoint = (-4 , 1.5)

Here we would be using the midpoint formula to find the co-ordinates of the line segment joining the two given points.

Step-by-step explanation:

Answer:

Company A:

150 x 3 = $450

6/100 x 150 = $9

450 + 9 = $459

Company B:

3.10 x 150 = 465

4/100 x 150 = 6

465 + 6 = $471

Answer:

40 shots total.

Step-by-step explanation:

First, change the percentage to a decimal:

80% = 80/100 = 0.80

Next, divide the amount of baskets made (32) with the decimal gotten to get the  total amount of shots:

32/0.80 = 40

Brandon took a total of 40 shots.

Check. Divide 32 (shots made) with the 40 (total shots in all):

32/40 = 0.8 = 80%.
