A ) = $ 0.18/oz = 4.68/26
b) = $0.19/oz = 2.66/14= 0.19
a is a better buy
9) for every 5 babies they need 1 babysitter, so for 40 babies they will need 8 babysitters.
It’s number 4 because 1-3 aren’t on the left side
Answer:
36?
Step-by-step explanation:
Answer: 800pi inches
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move
