\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=1.5\\
h=18
\end{cases}\implies V=\pi \cdot 1.5^2\cdot 18

Solve the system and enter the smallest x-coordinate first
ankoles [38]
Answer:
(2,-3)(6,5)
Step-by-step explanation:
We can use substitution to get the equation: x^2-6x+5 = 2x-7
Solve:
x^2-6x+5 = 2x-7
x^2 = 8x-12
x^2-8x+12 = 0 (we now have a polynomial)
(x-6)(x-2) = 0 (set each equation to equal 0 and solve)
x-6 = 0 --> x=6
x-2 = 0 --> x=2
To get the Y coordinates:
y=2(2)-7 --> y = -3
y = 2(6)-7 --> y = 5

Check work:
5 = 6^2-6(6)+5 --> 5 = 36-36 +5 --> 5=5
-3 = 2^2-6(2)+5 --> -3 = 4-12+5 --> -3=-3

Emily is 46 years old. Colin is 11 years older than Emily. Dan is 5 years younger than Emily. What is the total of their combine
Nonamiya [84]

Answer:

144

Step-by-step explanation:

<u>Data:</u>

<em>Emily's age</em> : 46 years old

<u>Find Colin's age</u>

<em>Colin's age</em>: 11 years older than Emily

                    Emily's age + 11

                    46 + 11 = 57 years old

<u>Find Dan's age</u>

<em>Dan's age</em>: 5 years younger than Emily

                  Emily's age - 5

                  46 - 5 = 41 years old

<u>Find their combined ages</u>

<em>Combined ages</em>: Emily's age + Colin's age + Dan's age

<em>Combined ages </em>= 46 + 57 + 41

Total = 144

Therefore, the total of their combined ages is 144.
