Can i get help plz its not hard
Sergio [31]

Answer:

1237 cubic feet

Step-by-step explanation:

First find the radius of the top D/2=r * r * pi

so 15/2=7.5*7.5*3.14=176.625

then multiply that by the height: 176.625*7=1236.375

So the volume of this figure is 1237 cubic feet!

Hope this helps!! :)

Partitioning- finding the endpoint
ElenaW [278]

Values of x and y will be 12 and 5 respectively.

It's given in the question,

  • Three points Q, R and S are collinear.
  • Coordinates of Q → (2, 0)
  • Coordinates of R → (8, 3)
  • Coordinates of S → (x, y)
  • QR : RS = 3 : 2

Since, expression for the coordinates of a point (h, k) which divides the segment joining points (x_1,y_1) and (x_2,y_2) in the ratio of m : n is given by,

h = \frac{mx_2+nx_1}{m+n}

k = \frac{my_2+my_1}{m+n}

Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,

8=\frac{3x+2\times 2}{3+2}

8=\frac{3x+4}{5}

3x+4=40

3x=36

x=12

Similarly, 3=\frac{3y+2\times 0}{3+2}

3=\frac{3y}{5}

3y=15

y=5

       Therefore, values of x and y will be 12 and 5 respectively.

adelina 88 [10]

Answer:

x/2 + x = 30 -> $2.50

20/2 + 20 = 30

X = 20, therefore:

dimes = 20

nickels = 10
