A turtle swims at a speed of 12 mph. A boy swims at a speed of 4.4 ft per s.

1 answer:

4 0

To compare the speed for the both of them, it would be helpful to convert the units to the same units in this case to units of yards per minute. We calculate as follows:

12 / 60 minutes = 0.2 miles/minute
0.2 × 5280 ft = 1056 ft/minute
1056 / 3 ft = 352 yds/minute

4.4 x 60 = 264 ft/minute
264 / 3 = 88 yds/minute

352 - 88 = 264 yds/minute faster than the boy

Sophie [7]

Answer:

a) 4

b) 12

Step-by-step explanation:

Since, when an orange ball is drawn, three coins are tossed. So, sample points are OHHH, OHHT, OHTH, OHTT. OTHH, 0THT, OTTH, OTTT

So, clearly, 8 sample points will have an orange ball.

When a blue ball is drawn, two coins are tossed. So, sample points are BHH,BHT,BTH,BTT.

So, clearly, 4 samples points will when a blue ball is drawn.

Total samples points=4+8=12

How do I solve this using the Pythagorean theorem

charle [14.2K]

Answer:

x=3

Step-by-step explanation:

First would need to convert the radical into a number.

And since if you have a perfect square of a radical it goes outside the square root sign, you would take the 3 and square it to make 9 and then take the 2 inside the square root sign and multiply so you have the square root of 18|

Since we have $\sqrt{18}$ as the Leg c we would need to square it, squaring a square root sign would just cause them to be cancelled out and you being left with 18, afterwards find the square of 3, which is 9
