Height covered by the plane=h= 500 feet
Distance covered by the plane along the ground=d= 2 mile
Now, convert the mile into feet,
1 mile = 5280 feet
2 mile = 10560 feet
Now, use the formula
h= d tanθ
tanθ= h/d
tanθ= 500/10560
tanθ= 25/528
Take the tan⁻¹ on both side,
θ= tan⁻¹(25/528)
θ =2.71°

∗ l = 50.6 ft
∗ w = ?
∗ The length is 50.6 feet. The question is saying that 50.6 is 5.8 feet less than 6 times the width.
∗ 6w - 5.8 = 50.6
∗ 6w = 56.4
∗ w = 9.4
Now lets check.
∗ If the length is 5.8 feet less than 6 times the width, and we found 9.4 as the answer, then;
6 times 9.4 - 5.8 should equal 50.6
∗ 6 • 9.4 - 5.8 = l
∗ 56.4 - 5.8 = l
∗ 50.6 = l
⋆The width is 9.4 feet⋆

Answer: D) No; If x is 5, the expression on the left simplifies to 8, making the inequality false.
In other words, if x = 5, then x+3 becomes 5+3 which ultimately becomes 8, but this is not greater than 8 on the right side.
Your steps could look like this
x+3 > 8
5+3 > 8 ... replace x with 5
8 > 8 ... this is a false inequality
Answer:
£2,120.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 2000(1 + (0.03 × 2)) = 2120
A = $2,120.00
The total amount accrued, principal plus interest, from simple interest on a principal of £2,000.00 at a rate of 3% per year for 2 years is £2,120.00.
