Answer:
60%
Step-by-step explanation:
To make a percent, it needs to be out of 100. So, the fraction would be 15/25. To make it 100, multiply each by 4 to get 100 since 25 times 4 equals 100. 15 times 4 is 60, so its 60 percent.
Answer:
The formula for circumfernce is C=pixd D is diameter
Step-by-step explanation:
Answer:
C only
Step-by-step explanation:
C is the only one which is correct as in all the other options x is cancelled out as both sides have 2x which gets cancelled leaving the equation with something like:
31=31 which is true but it's not considered a "solution" and as A, B and D end up with stuff like this they are all not 1 solution. For c, as c doesn't have a power on top of it, like does, its equation can only have 1 solution (or in some cases 0 solutions but this isn't one of them) so it is the correct answer.
Question #1
the answer is A
question #2
the answer is A
Answer:
True
Step-by-step explanation:
The formula for the area of a circle is πr² where r is the radius. So if 3 is the radius, plug it into the formula:
π(3²)
Simplify it:
π(9)
This can be rewritten as:
9π
