Answer:
If you know the radius of a circular track, you can use physics to calculate how fast an object needs to move in order to stay in contact with the track without falling when it reaches the top of the loop.
Think of it this way. Let's say t= one. 1+8 is 9. Your answer is 9t. Think of a variable without a number as one.
Answer:
Step-by-step explanation:
Total number of pairs of socks in a drawer = 10
Number of black pairs of socks = 5
Number of blue pairs of socks = 5
A. If you picked 2 socks [black] and [blue] 3rd pick guarantees you will have one pair of either blue or black
Number of socks you pull out to guarantee that you have a pair of one color = 3 socks
B. If you want to pick 2 good pairs and your 6 picks are worst case, so 7th pick of the socks will give you good pair of two colors.
Number of socks you pull out to have two good pairs = 7 socks
C. If you want to have a pair of black socks your worst case will be you pick all 10 blue socks so another 2 socks must be black.
Number of socks you pull out to have two black socks = 12 socks
Answer:
The answer top your question is: 1/2, 3/2, 5/2 and 7/2
Step-by-step explanation:
Data
4 consecutive numbers that add up to 8
First number = n
2nd number = n + 1
3rd number = n + 2
4th number = n + 3
Now, add them up n + n + 1 + n + 2 + n + 3 = 8
Simplify like terms
4n + 6 = 8
4n = 8 - 6
4n = 2
n = 2/4 = 1/2
First number = n = 1/2
2nd number = n + 1 = 1/2 + 1 = 3/2
3rd number = n + 2 = 1/2 + 2 = 5/2
4th number = n + 3 = 1/2 + 3 = 7/2
Answer:
The tank is 10cm high
Step-by-step explanation:
Given
-- length
-- width
--- water lever
Required
The height of the tank
Let y represents the remaining fraction before water is added.
So:
Make y the subject
Solve
Represent the volume of the tank with v
So:
Make v the subject
Substitute:
Represent the height of the tank with h;
So, the volume of the tank is:
Make h the subject
Substitute values for v, l and w
Convert 30L to cm^3
