A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:

sasho [114]

To find the volume of this storage bin, you will use the formula for volume of a cylinder and of a cone.

V = Bh (cylinder)
Pi x r^2 x h
Pi x 2^2 x 10

V = 1/3 x pi x r^2 x h
1/3 x pi x 2^2 x 3

All of these choices show correct answers!

You are hired to work at quickie-mart and will be paid $9.50 per hour 1. Write an income function that describes the amount of m

zzz [600]

Answer:

f(x)=nx

f(x)=9.50x

Step-by-step explanation:

Let x be the amount of hours and n be the hourly rate (9.50).

$f(x)=nx$

or if you prefer to use 9.50 instead of n, the function would be:

$f(x)=9.50x$

Determine which method works, substitution or elimination? 4x^2+3y^2=42x^2-6y^2=-3

GarryVolchara [31]

Given:

$\begin{gathered} 4x^2+3y^2=4 \\ \\ 2x^2-6y^2=-3 \end{gathered}$

Find the method .

Sol:

$\begin{gathered} 4x^2+3y^2=4..............(1) \\ \\ 2x^2-6y^2=-3.............(2) \end{gathered}$

2eq(1) + eq(2) then,

$8x^2+6y^2=8$

Then apply the elimination method.

$\begin{gathered} 8x^2+6y^2=8 \\ 2x^2-6y^2=-3 \\ --------- \\ 10x^2=5 \\ \\ x^2=\frac{5}{10} \\ \\ x=\sqrt{\frac{1}{2}} \end{gathered}$
