An engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it
swat32

Answer:

d=117.33 m

Step-by-step explanation:

Initial velocity of planes, u = 0 (because they are at rest)

Acceleration, a = 3.3 m/s²

Final take off speed, v = 88 m/s

We need to find the minimum allowed length for the runway. Let it is d. d will be the distance. It can be calculated using third equation of motion as follows :

v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}

Putting all the values, we get :

d=\dfrac{88^2-0^2}{2\times 33}\\\\d=117.34\ m

Hence, the minimum allowed length for the runway is 117.33 m.

Jacob wants to buy a $500,000 15-year term life policy, and the annual premium rate (per $1000 of face value) for his age group
kykrilka [37]

If Jacob lives until the end of the term of his policy, the total amount he would have paid in premiums overall is $50,850.

<h3>How much would he have paid in premiums?</h3>

Total premium payment = (face value / average premium rate) x number of years x premium

($500,000 / 1000) x $6.78 x 15 = $50,850

Over 11.2 hours, the temperature changed -2.9 degrees each hour. What was the total temperature change? Enter your answer in the
Doss [256]

Answer:

Total temperature change = -32.48 degrees

Step-by-step explanation:

Over 11.2 hours, the temperature changed -2.9 degrees each hour.

Total time elapsed = 11.2 hour.

Temperature change per hour = -2.9 degrees

Total temperature change = Total time elapsed x Temperature change per hour

Total temperature change = 11.2 x -2.9 = -32.48 degrees

So temperature is reduced by 32.48 degrees in 11.2 hours.

Total temperature change = -32.48 degrees

Suppose the total cost for n tickets is $36 what's is the total cost of one more ticket is purchased
arsen [322]
$36/n because since there are n amount of tickets, you should divide $36 by n. I feel like you won't get me. For instance, let's say n is 6 tickets. So if 6 tickets are for $36, you should divide $36 by 6 tickets to find the unit rate. Hope this helps.
