A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72. How much was the bill before applying the voucher discount code.

£91.80

Step-by-step explanation:

You first have to think, what is 15% of £36.72?

To do this, simply divide 100 by 3672, as we converted £36.72 to pence.

So 3672/100= 36.72. Then we multiply it by 15, which gives us 550.8

We then convert it back to pounds.

After you work that out you will get an answer of £55.08

We then add £55.08 to £36.72 and that will give us the answer, which is...

£91.80

OR

A quicker way is 15/100 of £36.72. Add the answer to £36.72= £91.80

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
