Answer:
Step-by-step explanation:
if a line AB is tangent to the circle with centre O then radius OA ⊥AB and AB touches it at exactly one point.
Answer:
Step-by-step explanation:
8)
around the tank = 12 * circumference
circumference = d
c = 30
c = 94.2477796
area around tank = 12 * 94.2477796 = 1130.973355
now top of tank
area of a circle = 
*
= 706.858347
add the two surface areas together for the total
706.858347 + 1130.973355 = 1837.832
total surface area = 1837.8 
10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is
*
* 10 = 282.7
Answer:
It's easier if you just turn them into decimals
We know there are 3 backpacks. So when we add the known values 9 3/4 and 1 3/4, we get 11 1/2. So 32- 11 1/2 will give you the pink backpack weight which is 20 and 1/2 pounds.
Answer:
Suppose we have a random number A.
The multiplicative inverse of A is a number X such that:
A*X = 1
When we work with real numbers, X = 1/A
Then:
A*(1/A) = A/A = 1
This means that (1/A) is the multiplicative inverse of A.
Where we need to have A ≠ 0, because we can not divide by 0.
Now we want to find the multiplicative inverse of the numbers:
2: Here the inverse is (1/2) = 0.5
1/5: Here the inverse is (1/(1/5)) = (5/1) = 5
-4: Herre the inverse is (1/(-4)) = -(1/4) = -0.25
