First, you have to do some factorization
60 = {1,2,3,4,5,6,10,12,15,20,30,60}
72 = {1,2,3,4,6,8,9,12,18,24,36,72}
the GCF is 12
now we find the number that you multiply by 12 to get 60 and another number to get 72.
12 x 5 = 60
12 x 6 = 72
now we notice if you add 60 + 72, we can now tell that it also equals (12)(5)+(12)(6)= 12(5+6)
Answer:
1/12
Step-by-step explanation:
There is only number between 1 and 12 that is both a multiple of 5 and 2, that being 10. 10 has an equal chance out of all the other numbers that can be spun, and there are 12 numbers, so 10 has a 1/12 chance of being spun.
Answer:
a)219.8
b)3846.5
Step-by-step explanation:
a) circumference is pi*diameter, so 3.14*70 is 219.8
b) area is pir^2, and radius is 1/2 of diameter, it would be 3.14*35^2, so 3.14*1225, so 3,846.5 in^2.
Answer:
for Part A
Answer is C.
Step-by-step explanation:

Here the angle, a is 60°, Opposite is 20 and adjacent is x.
Therefore we have,

Making x the subject gives us

Part B
Value of x to the nearest tenth
