Answer:
Step-by-step explanation:
- Height of cone (h) = 7 cm
- Formula for Volume of cone is given as:
- Plugging the values of h and r in the above formula, we find:
Answer: I think f
Step-by-step explanation:
P = 2(L + W)
P = 50
L = 15
50 = 2(15 + W)
50 = 30 + 2W
50 - 30 = 2W
20 = 2W
20/2 = W
10 = W.....so the width is 10 inches
No because the x and y axis are not suppose to be the same
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
