Answer:

2 hours

Step-by-step explanation:

using the relationship

distance = speed × time, then

time = \frac{distance}{speed} = \frac{30}{15} = 2 hours

2 hours because in one hour the cyclist biked 15 miles. That means you could follow the formula 30=15x where 30 is the total distance traveled and x=the number of hours cycled.
(You could solve it two ways)
1. Division:
30=15x ⬅️divide each side by 15
2=x ⬅️ 15 cancels out and you’re left with x=2

2. Multiplication: (you can use to check answer also)
30=15x; x=2
30=15(2) ⬅️ plug in 2
30=30 ✅

The Ferris wheel has a radius of 70 feet. The distance between the wheel and the ground is 4 feet. The rectangular coordinate sy
Leya [2.2K]

Answer:

The equation of the circular wheel is x^2+(y-74)^2=(70)^2.

Step-by-step explanation:

Given :

Radius of Ferris wheel r = 70 feet.

The distance between the wheel and the ground = 4 feet.

Also, the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel.

So the x coordinate of center of wheel must  be 0 , and y coordinate = 70 + 4 = 74

Thus, Coordinates of center = (0,74)

The equation of circle is given by :-

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

Now center (h,k) = (0,74) and r = 70 , we get

x^2+(y-74)^2=(70)^2

Hence, the equation of the circular wheel is x^2+(y-74)^2=(70)^2.

Suppose the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ =
Natali [406]
Answer: The proportion that will qualify is 0.0314 or 3.14%.

First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.

(128 - 141) / 7 = -1.86

Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.

Angel and Jayden were at track practice. The track is 2/5 kilometers around.  Angel ran 1 lap in 2 minutes.  Jayden ran 3 laps
choli [55]

Answer:

6/25 km in 1 min; or 0.24 km/min

Step-by-step explanation:

The info about Angel is not necessary.

Jayden runs 3 laps in 5 mins

Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.

Distance = rate x time

6/5 km = rate (5 min)

We want to isolate r (rate), so divide both sides by 5 min

6/5 km ÷ 5 min = r

6/5 km (1/5 min) = r

6/25 km/min = r  (notice how the units worked out correctly to km/min)

So, Jayden runs 6/25 km in 1 min.
