4/9 divided by 2/3 divided by 5/6 = 4/5
when you divided by two fractions, you can flip the denominator and numerator and then mutiply
4/3 pi r^3 = 9203
r^3 = 9203 / (4/3 * 3.14) = 2198.17
radius r = 13 inches (A)
Answer:
sorry for the questions i am not able to give answer
We will be using the formulas:
speed=distance/time
time=distance/speed
distance=speed×time
First let's find out Diane's rate of swimming. We can measure this by finding the slope (y/x) of a given coordinate on the graph. One point is (10,15), so you do 15/10=1.5m/s
Now for Rick's rate of swimming, just take a pair of values from the table. 12.5/10=1.25m/s
By the way m/s is metres per second for this
So at a constant speed of 1.5m/s, Diane swam 150m in 150/1.5= 100 seconds, or 1 minute 40 seconds
And at a constant speed of 1.25m/s, Rick swam 150m in 150/1.25= 120 seconds, or 2 minutes.
So the difference between their two times is 20 seconds

Step-by-step explanation:
9(5x)=45x
9(2)=18
4(8)=32
4(-x)=-4x
45x-4x=41x
32+18=50
41x+50
