Trey had a cylindrical can with a radius of 4 inches and a height of 12 inches that was completely full of beet juice. He poured

Arisa [49]

Answer:

$8\ glasses\ of\ juice$

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4\ in\\ h=12\ in$

substitute the values

$V=\pi (4)^{2}(12)=192\pi\ in^{3}$

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=2\ in\\ h=8\ in$

substitute the values

$V=\pi (2)^{2}(8)=32\pi\ in^{3}$

Find the volume of 3/4 of the glass

$32\pi (\frac{3}{4})=24\pi\ in^{3}$

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

$192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice$

Please solve for "a"<br><br> f(d)=ad^2+b100+10

Alenkinab [10]

$f(d)=ad^2+b100+10\\
f(d)=ad^2+100b+10\\
ad^2=f(d)-100b-10\\
a=\dfrac{f(d)-100b-10}{d^2}$

2x+9y=27<br> X - 3y = -24

allsm [11]

I assume that this is a system of equations so I'll use the substitution method.

Make one of the equations equal an isolated variable and since x is already isolated just add -3y on both sides.
x-3y=-24
+3y +3y

x=3y-24

Substitute that in for the first equation.

2(3y-24)+9y=27
6y-48+9y=27
15y-48=27
+48 +48
------------------
15y=75
----- ----
15 15

y=5

Substitute y in the other equation and find x

x-3(5)=-24
x-15=-24
+15 +15
--------------
x=-9

Ethan and Adrian are reading the same book. At the beginning of the month, Ethan was on page 18 and Adrian was on page 45. Ethan

xxMikexx [17]

The equations are e = 18+12t and a = 45+9t

Adrian will be father along in the book after 4 days. She will be 15 pages ahead of Ethan

Ethan's page number at the beginning of the month = 18

Adrian's page number at the beginning of the month = 45

Pages read by Ethan each day = 12 pages

Pages read by Adrian each day = 9 pages

Let e represent the page of the book that Ethan is on at the end of t days into the month. Let a represent the page of the book that Adrian is on at the end of t days into the month.

Formulating the equation we get the following:

e = 18 + 12t

a = 45 + 9t

Finding the page number of both Ethan and Adrian after 4 days by substituting the values in the equations we get:

e = 18+12(4)

e = 66

a = 45 + 9(4)

a = 81
