Answer:

Step-by-step explanation:

$a^{2} +b^{2}=c^{2}$

$2^{2} +b^{2} = 6^{2}$

4 + $b^{2}$ = 36

$b^{2}$ = 32

b = $\sqrt{32}$

CAN SOMEONE HELP ME PLEASE!!!

$t^2 - 75 = 0$

Add 75 to the other side to isolate the $t^2$

$t^2 = 75$

Take the square root of both sides to cancel out the $t^2$

$\sqrt{t^2} = \sqrt{75}$

t = 8.6602540

I'd round it.

t = 8.7

WORTH 100 POINTS

Answer:

The problem does not work.

Step-by-step explanation:

The plane with speed of 31 mph will cover 640 miles in $\frac{640}{31} = 20.64$ hours.

Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.

So, it will burn in 20.64 hours $\frac{5 \times 20.64}{0.05} = 2064$ gallons.

Now, the helicopter with speed of 45 mph will cover 640 miles in $\frac{640}{45} = 14.22$ hours.

Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.

So, it will burn in 14.22 hours $\frac{7 \times 14.22}{0.083} = 1194.48$ gallons.

But both of them starts with only 80 gallons of fuel.

Therefore, the problem does not work. (Answer)
