The answer to the question is B
Answer:
The car has traveled 405 miles if it has 2.5 gallons of gas left in the tank.
Step-by-step explanation:
16 - 2.5 = 13.5 ( The amount of gas the car has already used )
30 * 13.5 = 405 ( How far the car traveled with 13.5 gallons of gas )
Hope this helps!
.75x-14=-8
Use inverse operations to find x
Add 14 on both sides
.75x=6
divide by .75 on both sides
x=8
When rocket hit the ground the height of rocket from the ground is 0. So y = 0, when rocket hit the ground.
Simplify the equation -16x^2+248x+116 = 0 by using quadratic formula to obtain the value ot time, x.
The negative value of time is neglected as time can never be negative.
Thus time at which rocket hit the ground is 15.95 seconds.
