Answer: C= Pi times diameter
Step-by-step explanation:
A good way to remember circumference and area of circles is the sentence " Cherry pie delicious, Apple Pies are two."
Step-by-step explanation:
You have 3/5 of an apple pie" means you have 3 pieces of the 5-piece pie
"You divide the remaining pie into 5 equal slices." means
(3/5 pie) / 5
The math:
(3/5 pie) / 5
is also
(3/5 pie) * (1/5) [to divide by fraction 5/1, invert to 1/5 and multiply]
is also (1/5) * (3/5 pie)
[This means 1/5 of the 3/5 of a pie that is left of"]
So,
each slice is (1/5)*(3/5) pie = 3/25 pie [multiply numerators and denominators]
These ones always feel weird. But we will read the problem directly and do what it says.
So it is 3/5 divided by 5.
Or 3/5/5.
But that looks really weird, so lets think of it like multiplying by 1/5 instead (which is the same as dividing by 5)
So, (3/5) * (1/5) which equals 3/25.
Everyone gets 3 twenty fifths of a pie.
The greatest common factor is 2
This is because we start by taking the largest factor that goes into both coefficients. Since the first coefficient is 2, we have to try 2 and 1. Since 2 is larger and goes into 36 evenly, we use that.
Then we use the smallest number of each variable. There are 4 r's in both equations. So, that is the number that we take. There are 2 s's in the first term, so we take that number.
3x = x + 8
-x -x
2x = 8
/2 /2
x = 4
since angle L and N are the same you would set the 2 sides equal to each other
Answer:
12:28 = 3:7
Step-by-step explanation:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 12 and 28 is 4
Divide both terms by the GCF, 4:
12 ÷ 4 = 3
28 ÷ 4 = 7
The ratio 12 : 28 can be reduced to lowest terms by dividing both terms by the GCF = 4 :
12 : 28 = 3 : 7
Therefore:
12 : 28 = 3 : 7
