Answer: 121.5 pi in^3 or 381.7 in^3
Step-by-step explanation:
Volume of a cylinder = pi r^2(h)
Radius = 4.5 in, Height = 6 in
pi (4.5)^2(6)
pi(20.25)(6)
121.5 pi in^3 or 381.7 in^3
Find the reciprocal of 3/5 (by flipping the fraction)
5/3
Multiply 5/3 by 3/4
3/4(5/3)= 15/12= 1 1/4
Martina can walk 1 1/4 miles in one hour.

Answer:
Part A: The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is 1/3. This is because triangle P'Q'R is smaller than PQR by 1/3
Part B: The coordinates after P"Q"R" are P"(1, -2) Q"(0, -3) R"(-1, 0)
Part C: No the triangles are not congruent because they are not the same size. If there wouldn't have been a dilation or reflection then it would've been congruent.
Step-by-step explanation:
I did this Exam already and got a 100% good luck.
So this is a solution problem the answer is 3/4 cups or 75% milk and 1/4 cups or 25% cream, here's why:
m = milk
c = cream
m + c = 1
This is because when you add milk and cream then you get one cup of solution
.02m + .18c = .06
When you add together the percentages the goal is to have .06 or 6%
100m + 100c = 100
2m + 18c = 6
I do this to make it easier to solve
200m + 200c = 200
-200m - 1800c = -600
The "m's" cancel out
-1600c = -400
c = 1/4 or .25 or 25%
Now we add c back in
m + 1/4 = 1
Solve for m
m = 3/4
Thus: 3/4 milk and 1/4 cream
