Answer:
your answer would be $13.50 because is 3 bags cost 6.75 and you need 6 bags then just multiply the 6.75 by 2 and you get your answer :)
Step-by-step explanation:
Answer:
Height of the fighter plane =1.5km=1500 m
Speed of the fighter plane, v=720km/h=200 m/s
Let be the angle with the vertical so that the shell hits the plane. The situation is shown in the given figure.
Muzzle velocity of the gun, u=600 m/s
Time taken by the shell to hit the plane =t
Horizontal distance travelled by the shell =u
x
t
Distance travelled by the plane =vt
The shell hits the plane. Hence, these two distances must be equal.
u
x
t=vt
u Sin θ=v
Sin θ=v/u
=200/600=1/3=0.33
θ=Sin
−1
(0.33)=19.50
In order to avoid being hit by the shell, the pilot must fly the plane at an altitude (H) higher than the maximum height achieved by the shell for any angle of launch.
H
max
=u

sin

(90−θ)/2g=600

/(2×10)=16km
It is B Because you are finding the intrest rate which means find the rate first hen subtract the actual rate to the interest rate<span />
Answer:
The Jesse swim fastest
Step-by-step explanation:
Given as :
The distance cover by Elizabeth while swimming = 50 feet
The time taken by Elizabeth = 10 sec
So, Speed of Elizabeth = 
∴ Speed of Elizabeth = 
= 5 feet per sec
Again ,
The distance cover by Jesse while swimming = 110 feet
The time taken by Jesse = 20 sec
So, Speed of Jesse =
∴ Speed of Jesse = 
= 5.5 feet per sec
Again ,
The distance cover by Reagan while swimming = 160 feet
The time taken by Reagan = 30 sec
So, Speed of Reagan =
∴ Speed of Reagan = 
= 5.3 feet per sec
So, 
Hence The Jesse swim fastest Answer
