Answer:
7
Step-by-step explanation:
x = - 2
y = 4x - 1
= 4 ( 2 ) - 1
= 8 - 1
y = 7
ANSWER:
We know that,
Speed = Distance/Time
So, Time taken = 20kmh-¹/160km
Answer: Choice A) cone
One way to picture this is to think of a propeller. As the propeller spins, it carves out a 3D space even though the blade is "2D" in a sense.
If we spin everything around segment BC, we get a 3D cone forming. The base of the cone is vertical and it has a radius of AC. The height of the cone is segment BC. It might help to rotate the paper 90 degrees clockwise so that BC is vertical.
The length is 24 because 768 is the are and to find area you would do length x width but in this case the width has already been told so you have:
32 X____=768
so you do 768÷32= 24 so that's your answer sorry for such a long explanation which probably wasn't necessary but oh well!
The nearest whole number would be 93 because you round up if the decimal place is greater than 5 and down if it's less.
