Any number divisible by 3 is divisible by 6.
dimaraw [331]

Answer:

C.) False, counterexample of 15

1) 15 is divisible by 3 but not by 6

we know that 15 = 3*5 or 15/3=5, So 15 IS DIVISIBLE BY 3

BUT 15/6=2.5 THIS PROVES 15 IS NOT PERFECTLY DIVISIBLE BY 6

2) 12= 3*4 & 6*2

SO 12 IS PERFECTLY DIVISIBLE BY 3 & 6 BUT 15 IS NOT. THUS THE ANSWER IS 'C'

Matt measures a subway token and calculates that it has an area of 254.34 square millimeters. What is the token's circumference?
aivan3 [116]

Answer:

The token's circumference is 56.52\ mm

Step-by-step explanation:

step 1

Find the token's radius  

The area of the circle is equal to

A=\pi r^{2}

we have

A=254.34\ mm^{2}

so

254.34=(3.14)r^{2}

r^{2}=254.34/(3.14)

r^{2}=81

r=9\ mm

step 2

Find the token's circumference  

The circumference of the circle is equal to

C=2\pi r

we have

r=9\ mm

substitute

C=2(3.14)(9)=56.52\ mm
