Answer:
C/d = 31.4/10
Step-by-step explanation:
We know the formula of the circumference, which ir:
C = pi*d
Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:
C/d = pi*d/d
C/d = pi
Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:
pi = 31.4/10 = 3.14
And 3.14 is how we usually use the pi number.
Answer:
119 Cans Left
Step-by-step explanation:
If bob brought 16 packs of soda, and each pack had 8 cans, there would be 128 cans. This is because 1 pack is worth 8 cans.
16 × 8 = 128
128 - 9 = 119
Bob drank 9 of the cans, which is the same as subtracting from 128. This gives us the answer.
Answer:
$425
Step-by-step explanation:
Let washer be w
Let dryer be d
If d =x then w=x +74
x+x+74=924
2x+74=924
2x=850
dividing both sides by 2
x=425 hence d which is the dryer is $425
John would make <em>4,500$</em> for the 30 days he worked 25$ for 6 hours.
