Answer:

Kim will need to spend 67 minutes on her sixth ride

Step-by-step explanation:

Represent the number of minutes of her sixth ride by m.

Then the average number of minutes is

53 + 43 + 56 + 54 + 45 + m

---------------------------------------- = 53

6

Multiplying both sides of this equation by 6 yields

6(53 + 43 + 56 + 54 + 45 + m)

--------------------------------------------- = 6(53)

6

which simplifies to

251 + m

---------------- = 318

or 251 + m = 318. Subtract 251 from both sides to obtain the value of m:

m = 318 - 251 = 67

Kim will need to spend 67 minutes on her sixth ride to attain an average ride length of 53 minutes.i

Find the Shaded area

Paul [167]

Answer:

7.73

Step-by-step explanation:

So first find the area of the circle which is A= (pi)(r)^2

So you would have A=(pi)*3^2 = 28.27

Then you know that since the radius is 3 you know that the diameter is double of that and so your diameter is 6. Now if you draw a horizontal line that goes through the center and is parallel to one of the sqaure side you can see that that also is the diameter and you already figured out the diameter to be 6 so hence the side of the square are 6. Now find the area of the square which is 36 and then subtract 28.27 from it

36-28.27 = 7.73
