The radius is always half of the diameter so it would be 20 inches

--------------------------------------------------
Formula :
--------------------------------------------------
Volume = Length x Width x Height

--------------------------------------------------
Find volume :
--------------------------------------------------
$\text { Volume = } 4\dfrac{1}{4} \times 5 \times 2$

--------------------------------------------------
Change to improper fractions :
--------------------------------------------------
$\text { Volume = } \dfrac{17}{4} \times \dfrac{5}{1} \times \dfrac{2}{1}$

--------------------------------------------------
Combine into single fraction :
--------------------------------------------------
$\text { Volume = } \dfrac{170}{4}$

--------------------------------------------------
Simplify:
--------------------------------------------------
$\text { Volume = } 42 \dfrac{1}{2} \ cm^3$

--------------------------------------------------
Answer: Volume = 42 1/2cm³ (Answer c)

Y=x+6 on a coordinate plane. (3 points graphed).

Second Point: For

We can next plot the two points on the coordinate plane:

graph{((x-6)^2+y^2-0.035)((x-4)^2+(y-2)^2-0.035)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(y+x-6)((x-6)^2+y^2-0.035)((x-4)^2+(y-2)^2-0.035)=0 [-10, 10, -5, 5]}

Combine like terms. What is a simpler form of the expression

pickupchik [31]

First, distrbute -3 to both -4y and 3

-3(-4y) = 12y -> note that two negatives multiplied = one positive answer

-3(3) = -9 -> note that one negative and one positive = one negative answer

12y - 9 + 7y -> combine like terms

12y + 7y - 9

19y - 9 -> answer

Your answer is 19y - 9

hope this helps
