Can you add more to this question, I have no idea what you are asking
35 I had this for a test the answer is
Answer:
The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.
Step-by-step explanation:
Given that:
Distance traveled by jet against the wind = 2480 miles in 4 hours
Combined speed = =
Combined speed = 620 miles per hour
Distance traveled with wind = 7040 miles in 8 hours
Combined speed =
Combined speed = 880
Let,
Speed of jet = x
Speed of wind = y
When jet travels against the wind, the speed will be subtracted
x-y=620 Eqn 1
When jet travels with the wind, the speed will be added
x+y=880 Eqn 2
Adding Eqn 1 and 2
(x-y)+(x+y)=620+880
x-y+x+y=1500
2x=1500
Dividing both sides by 2
Putting x=750 in Eqn 2
750+y=880
y=880-750
y=130
Hence,
The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.
Answer: a) interest earned is $308.2
b) $1983.2
Step-by-step explanation:
a) Interest is calculated by Principal × Rate × Time
From the question, principal is given as $1675; rate = 4.6% = 4.6/100 = 0.046; Time = 4 years
Slot the values into the formula to get the solution
=1675 × 0.046 × 4
= $308.2
Interest earned is $308.2
b) Balance on the account will be Principal + Interest earned
= $1675 + $308.2
=$1983.2
I hope this is clear, please mark as brainliest answer.
