can you ask the question more clearly
Answer:
New altitude = 5.5 miles
Step-by-step explanation:
We are given;
Velocity = 400 m/h
Angle of descent = 1°
Altitude = 7.2 miles
Time = 15 minutes = 15/60 hours = 0.25 hours
Now, the downward component of its speed is;
Vy = (400)sin(1°)
Vy = 6.98 mph
After a time t, its height will be;
h(t) = (7.2 - 6.98t) miles, for t = hours
We are given;t = 0.25 hrs
Thus;
h(0.25) = 7.2 - (6.98*0.25) miles
h(0.25) = 5.46 miles
h(0.25) ≈ 5.5 miles to the nearest tenth
Answer: 30
Step-by-step explanation:
Given : In August, Emily's Clothing Store sold 460 shirts with the ratio of short sleeve to long sleeve being 3:7 .
Let the number of short sleeve shirts be 3x and the number of long sleeve shirts be 7x.
Then , according to the question, we have
Now, the number of short sleeve shirts sold =
Hence, 30 short sleeve shirts were sold.
