Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? (Round to the nearest w
Sonja [21]

Answer:

173/3 feet per second

Step-by-step explanation:

So we know that jackrabbits can travel at 40 miles per hour, and we are trying find how fast they can travel in feet per second. To do this, we must first convert the 40 miles per hour into feet per hour:

\frac{40mi}{1hr}*\frac{5280ft}{1mi}=\frac{211200ft}{1hr}

So now we know that 40 miles per hour is equal to 211200 feet per hour. Now we have to convert feet per hour to feet per second. To do this, we must first find the feet per minute (60 min = 1 hr):

\frac{211200ft}{1hr}*\frac{1hr}{60min}=\frac{211200ft}{60min}=\frac{3520ft}{1min}

So now we know that 211200 feet per hour is equal to 3520 feet per minute. Now we have to convert feet per minute into feet per second (60 s = 1 min):

\frac{3520ft}{1min}*\frac{1min}{60s}=\frac{3520ft}{60s}=\frac{176ft}{3s}=\frac{173}{3}ft/s

So now we know that 3520 feet per minute is equal to 173/3 feet per second.

Since 40 miles per hour equals 211200 feet per hour which equals 3520 feet per minute which equals 173/3 feet per second, 40 miles per hour equals 173/3 feet per second.

The jackrabbits can run at 173/3 feet per second.

I hope this helps. :)

What is the answer for <br> 6-3(n-2)=8-n
elena55 [62]

Answer:

n=2

Step-by-step explanation:

Simplify.

6−3(n−2)=8−n

6+(−3)(n)+(−3)(−2)=8+−n(Distribute)

6+−3n+6=8+−n

(−3n)+(6+6)=−n+8(Combine Like Terms)

−3n+12=−n+8

−3n+12=−n+8

Add n to both sides.

−3n+12+n=−n+8+n

−2n+12=8

Subtract 12 from both sides.

−2n+12−12=8−12

−2n=−4

Divide both sides by -2.

-2n/-2 = -4/-2

n=2

What is 16,700,000,000,000,000 estimated as the product of a single digit and a power of 10
Vesna [10]
Hello!

Another way to put it would be scientific notation. to do so, you would need to get a digit 1-10 multiplied by 10 to a certain power.

For this problem, scientific notation is 1.67(10^16).

To check our answer,  we will move the decimal to the right sixteen times because the exponent is positive. In other words, we will add fourteen zeros because we need two to turn 1.67 into 167. This gives us 16,700,000,000,000,000, which matches the question. (This number in word form is 16 quadrillion seven hundred trillion.)

Our final answer is 1.67(10^16).

I hope this helps!
