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!

What is the equation to the quadratic function that has zeros at -6 and 16?

ollegr [7]

Answer:

x^2 -10x -96 =0

Step-by-step explanation:

Subtract the zeros from x in factors

(x - -6) (x-16)

(x+6) (x-16)

Set these equal to zero since they are zeros

(x+6) (x-16) =0

FOIL

x^2 -16x+6x -96 =0

x^2 -10x -96 =0

Corey invested $1500 when he was a freshman in order to save for college. If he chooses to invest it in an account that earns 3.

Tcecarenko [31]

Answer: He will have $1721.28. after 4 years.

Step-by-step explanation:

The formula we use to find the compounded amount A is :

$A=P(1+r)^t$ , where P= principal value, r = rate of interest , t= time.

As per given , we have

P=$1500 , r=3.5%=0.035 , t= 4 years

Money he will have after 4 years = $1500(1+0.035)^4$

$=1500(1.035)^4\\\\=1721.28450094\approx1721.28$

Hence, he will have $1721.28. after 4 years.

Mei likes to make desserts for bake sales. Last month, she made 2 batches of brownies and 3 batches of cookies, which called for

tino4ka555 [31]

Answer: she uses 2 eggs for one batch of brownies and 4 eggs for one batch of cookies.

Step-by-step explanation:

Let x represent the number of eggs that she uses for one batch of brownies.

Let y represent the number of eggs that she uses for one batch of cookies.

Last month, she made 2 batches of brownies and 3 batches of cookies. This means that

2x + 3y = 16 - - - - - - - - - -1

The month before, she baked 1 batch of brownies and 1 batch of cookies, which required a total of 6 eggs. This means that

x + y = 6 - - - - - - - - - - - - - 2

Multiplying equation 1 by 1 and equation 2 by 2, it becomes

2x + 3y = 16

2x + 2y = 12

Subtracting, it becomes

y = 4

Substituting y = 4 into equation 2, it becomes

x + 4 = 6

x = 6 - 4 = 2
