Answer is c as the equation for the volume of a cylinder is pi x r^2 x h which equated to pi x 25 x 11 which equals 275 and your units have to be cubed as it is volume.
Answer:
The answers are that a = -5 and b = 1
Step-by-step explanation:
In order to find A and B, we first need to find the equation of the line. We can do this by using two ordered pairs and the slope formula. For the purpose of this activity, I'l use (0, 5) and (-3, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 5)/(-3 - 0)
m = 6/-3
m = -2
Now that we have this we can model this using point-slope form.
y - y1 = m(x - x1)
y - 5 = -2(x - 0)
y - 5 = -2x
y = -2x + 5
Now that we have the modeled equation we can use the ordered pair (a, 15) to solve for a.
y = -2x + 5
15 = -2(a) + 5
10 = -2a
-5 = a
And we can also solve for b using the ordered pair (2, b)
y = -2x + 5
b = -2(2) + 5
b = -4 + 5
b = 1
Answer:
Step-by-step explanation:
Let Vernice age be x
Her mother's age be 2x+10
10=1\2(2x+10) = 10×2=2x+10
20=2x+10
20-10=2x
10=2x
x=5
Answer:
The correct answer is H
Step-by-step explanation:
1/4 of a wall in 2/3 of an hour is 40 min
so a wall takes 160 min which is 2 hours and 40 min
so 3 walls takes 8 hours
Answer:
x=2
