Answer:

11 meters  is her approximate reaction distance.

Step-by-step explanation:

Speed of the car of Mindy = 32 mile/hour = \frac{32\times 1609.34 m}{3600 s}

1 mile = 1609.34 m

1 hour = 3600 seconds

Duration for her reaction last after student runs into street in front of her = \frac{3}{4} seconds

Distance covered three -quarters of a second = d

d=\frac{32\times 1609.34 m}{3600 s}\times \frac{3}{4} s

d = 10.73 m ≈ 11 m

11 meters  is her approximate reaction distance.

Can someone please help me with this?

The way this problem is stated is that you put 1 grain of rice on the first square, the second square has 2 grains of rice. The third square has 4 grains of rice and you keep on doubling from there. When you tell me there is a 0 square, I'm not sure what you mean.
That would mean (to me) that square 1 has 2 grains of rice
Square 2 has 4 grains of rice
Square 3 has 8 grains of rice
The table goes up to 64 squares on a chess board.
2^64 which is (rounded) to about 1.84 with 17 zeros behind the 1.84.
My calculator says the answer is 1.84 * 10^19
I think you want 
2^64<<<<<answer.
Or maybe
y =R(x) =  2^x <<<< answer.
where the domain is 0 <=x <= 64 contained in the integers.

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m
yawa3891 [41]
First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s =  <span>25.9504644 m/s.

Then we convert that into miles per hour by </span>2.23694, so we do:

25.9504644 * 2.23694 = <span>58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.

Hope this helped! c:</span>

Answer:

x = 48

Step-by-step explanation:

14^2 + b^2 = 50^2

196 + b^2 = 2500

-196           -196

b^2 = 2304

√b^2 = √2304

b = 48
