Answer:

4x-y= -18

Step-by-step explanation:

y-1=4(x+4)

y-1=4x+16

4x-y=-1-17

4x-y=-18

where A=4 B=-1 and C=-18

Answer:

4x + y = -15

Step-by-step explanation:

y - 1 = -4(x+4)

y - 1 = -4x - 16

y = -4x - 16 + 1

y = -4x - 15

4x + y = -15

A cylindrical can hold three tennis balls. The height of the stacked balls is 9 inches.~About what percentege of the volume of the can is NOT occupied by the tennis balls?
A 33%
B 45%
C 67%
D 75%

Answers

Since there are 3 and assuming that they're the same size each radius is 1.5, as is the radius of the base of the cylinder. So you have to figure out the volume of one of the balls and multiply it by three. Formula: (4/3) * pi * radius^3. The volume of all three is 42.42. Then you need to find the volume of the cylinder. formula: pi * h * r^2. So it is 63.62. You now take this measure and subtract the volume of the three balls: 21.2in^3. To find the percentage, take 21.2/63.62. Then multiply by 100. The answer is 33.32, so your final answer is A.

the answer to ur question is A 33%
