I think it’s 36 but I’m not good at math so don’t count me on it
5 2/3 divided by 2 2/3 = 17/3 divided by 8/3 = 17/8 = 2 1/8 miles per hour
2 2/3 divided by 5 2/3 = 8/3 divided by 17/3 = 8/17 hours per mile
Answer:
176.71 cm
or
56.25π cm
Step-by-step explanation:
The formula for the circumference of a circle is:
C = πd
Where C is the circumference and d is the diameter
Let's substitute the circumference given into this formula:
C = πd
15π = πd
Now, we can solve this equation for d.
Divide by π on both sides:
15π = πd
/π /π
15 = d
Therefore, the diameter is 15 cm.
We need to find the area. The formula for the area of a circle is:
A = πr²
First, let's find the radius. The radius is half of the diameter, so divide the diameter by 2.
15/2 = 7.5
radius = 7.5 cm
Now, we can solve for the area.
Substitute into the formula for area:
A = πr²
A = π(7.5²)
A = π(56.25)
A ≈ 176.71
Therefore, the area is approximately 176.71 cm, or in terms of pi, 56.25π.
We are given a scenario at which a jar contains the following slips for a raffle draw:
4 slips for a 5 percent discount.
y slips for an x percent discount
2 slips for a 15 percent discount
if the expected value on the next draw is 8 percent, the value of y can be determined by assuming that the 8% is the value of x.
If x = 8 percent then we can solve for the value of y by ratio and proportion:
4 / 0.05 = y/ 0.08
then y is approximately equal to 6 slips.
