Answer:
in terms or pi
simplified
Step-by-step explanation:
To solve this, we are using the Cylinder's volume formula:
where
is the volume of the cylinder
is the radius of the cylinder
Remember that radius is half the diameter, so we can divide the diameter of our cylinder by 2 to find its radius: . Now, 9 1/2 inches is 9 and a half inches, so .
Replacing values:
We can conclude that the volume of our cylinder is in terms of pi, or simplified.
Answer: 75 minutes.
Step-by-step explanation:
Given that the line a bus arrives at the bus stop every 25 minuetes, and the line B busarrived every 15 minuetes both are at the bus stop right now.
In how many minutes will both be at the bus stop again?
We can achieve that by finding the LCM of 25 and 15
The LCM of both will be 3, 5 and 5
That is, 3 × 5 × 5 = 75 minute.
Therefore, both will be at the bus stop again in the next 75 minutes or 1 hour 15 minutes.
Answer:
f(-1) = -3
Step-by-step explanation:
(Assuming {2} is ^2)
f(-1) = 3(-1)² + 4(-1) - 2
= 3(1) - 4 - 2 = -3
Answer:
x = 5
Step-by-step explanation:
x + (3x - 2) = 18
x + 3x - 2 = 18
4x - 2 = 18
+2 +2
--------------------------
4x = 20
/4 /4
--------------------------
x = 5
