The answer is B.
you add up all of the coins (all colors) and get thirty. which mean you have
?/30
if he draws 8 that is your numerator so you now have
8/30
after you get this you simplify so in this case you can simplify by 2. (simplifying is divine the top and bottom by the same number equally)
after you simply you get 4/15 (8÷2=4. 30÷2=15)
Answer:
1) 0
2) -6
Step-by-step explanation:
Any number to the ⁰th power is 1.
A negative exponent flips the fraction.
Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]
