A cycling race is 17 miles long. The cyclists will begin at point S and ride a number of laps around a neighborhood block. After

the last lap, the cyclists will sprint 2.0 miles to the finish line. A rectangle with a width of 0.75 miles and height of 0.5 miles. The 2 mile finish comes out of one corner. Using the equation w (1.5 + 1) + 2 = 17, the race's organizer determined the cyclists will need to ride 9 laps before the sprint to the finish. Which explains the error? The equation should be 0.75 w + 0.5 w + 2 = 17, and the cyclists will need to ride 12 laps before the sprint to the finish. The equation should be 2 (0.75 w + 0.5) + 2 = 17, and the cyclists will need to ride 21 laps before the sprint to the finish. The solution should be 6, and the cyclists will need to ride 6 laps before the sprint to the finish. The solution should be 8, and the cyclists will need to ride 8 laps before the sprint to the finish.

Find the diameter of a circle whose equation is
Olin [163]

Answer:

D) 20

Step-by-step explanation:

x^2 + (y - 2)^2=100

This can be rewritten as

(x-0)^2 + (y - 2)^2=10^2

This is in the form

(x-h)^2 + (y - k)^2=r^2

The radius is 10

The diameter is 2 times the radius

d = 2*r = 2*10 = 20

A distribution has a mean of 90 and a standard deviation of 15. Samples of size 25 are drawn randomly from the population. Find
raketka [301]

Answer:

The probability is 0.04746

Step-by-step explanation:

Firstly, we calculate the z-score here

Mathematically;

z-score = x-mean/SD/√n

Where from the question;

x = 85, mean = 90 , SD = 15 and n = 25

Plugging these values into the equation, we have;

Z = (85-90)/15/√25 = -5/15/5 = -1.67

So the probability we want to calculate is ;

P(z > -1.67)

We use the standard normal distribution table for this;

P(z > -1.67) = 0.04746

Surface Area of Cylinders - Item 1175
mylen [45]

The surface area is 47.1 sq in.

Step-by-step explanation:

Given,

The height (h) of the coin (cylinder shaped) = 5 inches

The radius (r) = 1.5 inches

To find the surface area of the coin.

We need to find the lateral surface area of the coin.

Formula

The surface area of the coin of radius r and height h is 2πrh.

Now,

Putting the value of h and r and π=3.14 we get,

Area = 2×3.14×1.5×5 sq inches

= 47.1 sq in

Hence, the surface area is 47.1 sq in.

tangare [24]
Oldest = 2x
Middle = x + 5
Youngest = x

2x + x + 5 + x = 57
combine like terms

4x + 5 = 57
subtract 5 from both sides

4x = 52
divide both sides by 4 to isolate x

x = 13

Oldest = 2x = 2(13) = 26
Middle = x + 5 = 13 + 5 = 18
Youngest = x = 13
