Answer:
≈ £ 4584.38
Step-by-step explanation:
Firstly, we need to find the number of litres that Mr. Leonard needs to fill up his tank:
We know that there is already 450 litres in the 1200 litre tank, so he must need 1200 - 450 = 750 litres.
I'm not quite sure what the variable p means, but I'm going to assume that p represents the number of litres and that 81.5 is the price per litre in pounds.
So:
Total price = 81.5p
Total price = 81.5(750)
Total price = £61125
We have to remember though that the question is asking for the <em>discount</em> and not the <em>discounted price</em>, so:
61125 × 7.5%
61125 × 0.075 = 4584.375
≈ £ 4584.38
Answer:
63.0
Step-by-step explanation:
area of circle = πr²
area of quarter circle = πr²/4
area of triangle = bh/2
area of shaded quarter circle:
πr²/4 = (3.14159)(7²)/4 = 38.4845 units²
area of shaded triangle:
bh/2 = (7)(7)/2 = 24.5 units²
total shaded area = 38.4845 units² + 24.5 units² = 62.9845 units²
Answer: 63.0 units²
The answer is (x+1)-(2x-4)=6
First, we get the length of the runway in which the pilot had seen a 45° by using the trigonometric formula of tangent.
tan 45° = 1,500 / x
The value of x from the equation is 1500 ft.
We do the same for the 42°
tan 42° = 1,500 / y
The value of y is equal to 1665.92 ft. To determine the length of the runway, we subtract the lengths calculated and this will give us an answer of 165.92 ft.
