Answer:
Correct option: second one
(Volume will be 9 times higher)
Step-by-step explanation:
The volume of a cylindrical can is given by the formula:
V = pi * r^2 * h
Where r is the base radius and h is the height.
If the new radius will be the triple of the old radius and the height will be the same, we have:
r' = 3r
h' = h
So, we can find the new volume V':
V' = pi * r'^2 * h'
V' = pi * (3r)^2 * h
V' = pi * 9r^2 * h = 9 * (pi * r^2 * h) = 9V
So we have that the new volume will be 9 times higher than the old volume.
Correct option: second one.
Answer:
Step-by-step explanation:
7-4(Y)
-4/y = 7/-4
7÷ -4 =-1.75
Given that, Joe travels 68 mi in 4 hours, the number of miles Joe will travel in 45 minutes is 12.75.
<h3>How many miles did joe travel in 45 minutes?</h3>
Given that;
- Joe travels 68 miles in 4 hours
- joe travel x miles in 45 minutes
First, we convert 4 hours to minutes: 4 × 60 = 240 minutes
Now,
Joe travels 68 miles in 240 minutes
Joe will travel x miles in 45 minutes
We have;
x × 240 = 68 × 45
x × 240 = 3060
x = 3060 / 240
x = 12.75 miles.
Given that, Joe travels 68 mi in 4 hours, the number of miles Joe will travel in 45 minutes is 12.75.

Answer:
(x, y) = (2, 5)
Step-by-step explanation:
Substitute the expression for y in the second equation into the first equation:
5x -5 = x +3
4x = 8 . . . . . . add 5-x to both sides
x = 2 . . . . . . divide by 4
y = 2+3 = 5 . . . substitute for x in the first equation
The solution is (x, y) = (2, 5).
