Point Q is the midpoint of GH¯¯¯¯¯¯ . GQ=2x+3, and GH=5x−5 .<br><br> What is the length of GQ¯¯¯¯¯ ?
AveGali [126]

Point Q is the midpoint of GH

so GQ = QH

Given GQ=2x+3, and GH=5x−5 .

2x + 3 = 5x − 5

3x = 8

x = 8/3

GQ = 2(8/3) +3

GQ = 16/3 + 3

GQ = 16/3 + 9/3

GQ = 25/3

GQ = 8 1/3

Mr Leonard wants to top-up his central heating oil tank. The oil tank can take up to 1200 litres of oil. There are already 450 l
garik1379 [7]

Mr. Leonard gets £ 45.84375 as discount

<em><u>Solution:</u></em>

The oil tank can take up to 1200 liters of oil

There are already 450 liters of oil in the tank

The remaining oil which is to be added is given by :

Remaining oil = 1200 - 450 = 750 liters

The price of oil is 81.5 p per liter

<em><u>Then calculate the total price of 750 L of oil:</u></em>

Total\ Price = 750 \times 81.5 = 61125

Thus total price is 61125 p

Mr Leonard gets a 7.5% discount on the price of the oil

Therefore,

Discount amount = 7.5 % of 61125

Discount\ amount = 7.5 \% \times 61125\\\\Discount\ amount = \frac{7.5}{100} \times 61125\\\\Discount\ amount = 0.075 \times 61125\\\\Discount\ amount = 4584.375

Thus he gets 4584.375 p

We convert p to £

1 p = 0.01£

4584.375 x 0.01 = £ 45.84375

Thus he gets £ 45.84375 as discount
