Answer:
out of 36 rolls, 15 were positive. 15/36 simplified is 5/12
Step One
Calculate the number of feet traveled in 1 rotation.
Formula
C = π*d
P = 3.14
d = 9 inches = 9/12 feet = 3/4 of a foot.
C = 3.14 * 3/4 = 2.355 So that means that every time the tire turns around 1 complete turn, the distance traveled on the ground is 2.355 feet.
Step Two
Figure out the number of revolutions.
1 revolution = 2.355 feet
x revolutions = 300 feet.
1/x = 2.355/ 300 Cross multiply
2.355 feet * x = 1 rev * 300 feet
2.355 x = 300 rev Divide by 2.355
x = 300 / 2.355
x = 127.39 revolutions. <<<< Answer
Answer: a) 4 b) you could make up to 8 liters
Step-by-step explanation:
The answer for the question is 163.5 because the equation is 2x-3ft=324ft. You add 3 to both sides which on the left it crosses out and on the right the answer is 327. Then you bring the 2x down and divide. So 327/2 is equal to 163.5
Answer:
Step-by-step explanation:
According to the problem, the initial condition is $200. If he owed $100 after 4 weeks, that means he paid $25 per week, so that would be the constant ratio. Therefore, the expression would be:
Where 
represents the amount owed, and 
represents weeks.
So, in the 4 week, that is, 
he owed:
As you can observe, the relation we found first perfectly to the problem. So, the final expression that model this problem is
