45.84 pounds

OK. This problem isn't that hard if you just take it in pieces.
First, calculate how much oil Mr Leonard needs to buy. That will be the capacity of his oil tank minus how much oil is already in it. So

1200 litres - 450 litres = 750 litres

Now figure out how much that 750 litres of oil will cost at full price.

750 litres * 81.5 p/litre = <span> <span>61125 p

Now, calculate how much is 7.5% of 61125 p

7.5% * 61125 p = 0.075 * 61125 p = </span></span><span> <span>4584.375 p

Finally, since there's 100 pence in a pound, divide the number of pence saved by 100. So
</span></span>4584.375 p / 100 = 45.84 pounds<span>

Solve for x. <br> 2(x-2)= 6x + 2 -2(-2x - 4)
Lena [83]

Answer:-7/4

Step-by-step explanation:

2(x-2)=6x+2-2(-2x-4)

Open brackets

2x-4=6x+2+4x+8

Collect like terms

-4-2-8=6x+4x-2x

-14=8x

Divide both sides by 8

-14/8=8x/8

-7/4=x

x=-7/4

An airplane pilot over the Pacific sights an atoll at an angle of depression of 5 . At this time, the horizontal distance from t
Aleonysh [2.5K]

Answer:

404.98 m

Step-by-step explanation:

The angle of depression is 5°

The horizontal distance from the airplane to the atoll is 4629 meters.

We need to find the height of the plane.

If we consider a triangle. 4629 meters will be the base and angle is 5°. Let h is the height of the plane. Using trigonometry to find it :

\tan\theta=\dfrac{x}{4629 }\\\\\tan(5)=\dfrac{x}{4629 }\\\\x=\tan(5)\times 4629 \\\\x=404.98\ m

So, the height of the plane is 404.98 m.

8x = -8

x = -1

(x, y) = (-1, 1)
