Pythagorean Theorm Unit? I got you!
It would be C, about 63.07
Answer:
X= 18
Step-by-step explanation:
24/4=6 x 3= 18
If she has 10/12 and uses 8/12 then you just subtract.
Since the denominators are the same you just subtract 10-8 and get 2
the denominator is the same for your answers and so it is
2/12
First you need to work out how much string is needed -
256 pieces needed x 40cm each:
256 x 40 = 10240cm
Then, convert to metres (100cm = 1m)
10240 / 100 = 102.4m
Then, you work out how many balls are needed:
30 can fit into 102.4 3 times with .41m to spare. So, you need three balls of string, PLUS another one to cover the 41cm
So to conclude: 4 balls of string are needed.
ANSWER
The correct answer is B

EXPLANATION
The given exponential expression is

We can rewrite this as,

We need to simplify to obtain a positive index, so we apply the following property,

This implies that,

This will finally simplify to,

Therefore the correct answer is B
