KIM [24]

Use the Pythagorean theorem:

$x^2+7^2=14^2\\\\x^2+49=196\qquad\text{subtract 49 from both sides}\\\\x^2=147\to x=\sqrt{147}\\\\x=\sqrt{49\cdot3}\\\\x=\sqrt{49}\cdot\sqrt3\\\\\boxed{x=7\sqrt3\ mi}$

$x^2+9^2=(\sqrt{226})^2\\\\x^2+81=226\qquad\text{subtract 81 from both sides}\\\\x^2=145\to \boxed{x=\sqrt{145}\ km}$

Answer:

1. The relative frequency of heads is (A) reasonably close to 40%.

2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.

3. This means that the theoretical probability of tails is most likely 0.6 for this coin.

How long dose it take to travel 5km at an average speed of 8 m/s? Give your answers in minutes and seconds

eduard

Answer:

625 seconds and 10 minutes

Step-by-step explanation:

distancs=S=5km=5000m

average speed=v=8m/s

time taken=t=?

as we know that

average speed= $\frac{distance covered}{time taken}$

average speed×time taken=distance covered

here we have to find the time taken

time taken= $\frac{distance covered}{average speed}$

time taken= $\frac{5000m}{8m/s}$

time taken=625seconds

now we convert seconds into minutes

$\frac{625}{60}$

10 minutes
