Georgia [21]3 years ago
4 0

The formula for volume of a cone = PI x r^2 x h/3

PI = 3.14

r = 8.5/2 = 4.25

h = 4.5

Volume = 3.14 x 4.25^2 x 4.5/3

Volume = 3.14 x 18.0625 x 1.5

Volume = 85.074375

Rounded to the nearest hundredth = 85.07 cubic cm.

Identify the k-value that makes the relationship shown in the table below proportional.​
uysha [10]

Answer:

The value of k that makes the relationship shown in the table below proportional is \mathbf{\frac{1}{2}}

Step-by-step explanation:

The relation is proportional if y=kx \:or\:k=\frac{y}{x}

Putting values of x and y to find k.

For x =2 and y =1 k is: k=\frac{y}{x}=\frac{1}{2}

For x =4 and y =2 k is: k=\frac{y}{x}=\frac{2}{4} =\frac{1}{2}

For x =6 and y = 3 k is: k=\frac{y}{x}=\frac{3}{6} =\frac{1}{2}

For x = 8 and y = 4 k is: k=\frac{y}{x}=\frac{4}{8} =\frac{1}{2}

For x =10 and y = 5 k is: k=\frac{y}{x}=\frac{5}{10} =\frac{1}{2}

So, The value of k that makes the relationship shown in the table below proportional is \mathbf{\frac{1}{2}}

Match the following expression 12(x-3)+18=4(2x-3) with the number of solutions below.
vfiekz [6]
12(x-3) + 18 = 4(2x-3)

12x-36+18 = 8x-12

12x -18 = 8x-12

12x-8x = -12 + 18

4x = 6

x = 6/4 or 3/2
