Answer: 20.5

Step-by-step explanation:

From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.

In a right angled triangle, the circumradius is half the hypotenuse.

In the given triangle, the hypotenuse = 41.

Therefore, the circumradius is  41÷2= 20.5 units.

The driver of a car traveling at a speed of 40 miles per hour had to stop the car quickly. If the driver`s reaction time was 34
natulia [17]

Answer:

The car travel 44 feet during the driver`s reaction time.

Step-by-step explanation:

The sentence "If the driver`s reaction time was 34 of a second"  has to be changed as "If the driver`s reaction time was 3/4 of a second"

If the driver drives at a speed of 40 miles per hour, it means s/he travels

40 × 5280 = 211200 feet per hour.

1 hour is 60 minutes and 1 minute is 60 seconds.

That is, 1 hour is 3600 seconds.

Therefore the driver travels \frac{211200}{3600} feet in a second.

And since the reaction time is \frac{3}{4} =0.75 of a second, the car travels \frac{211200}{3600 } * \frac{3}{4}=44 feet during the reaction time.

A cell phone weighs about 2.8X10^n pounds. Which value of n is most reasonable? A)-3 b)-1 c)0 d)1
krek1111 [17]
Just plug in every value and see if it's a reasonable weight for a cell phone.

\sf 10^{-3}=0.001
\sf 10^{-1}=0.1
\sf 10^0=1
\sf 10^1=10

\sf 2.8\times 0.001=0.0028
\sf 2.8\times 0.1=0.28
\sf 2.8\times 1=2.8
\sf 2.8\times 10=28

So what is the most reasonable weight for a cell phone? 0.0028 pounds, 0.28 pounds, 2.8 pounds, or 28 pounds? I would definitely say 0.28 pounds.
