1 answer:

6 0

Put it into standard form so you would have

27x10¯6 divided by 9x10¯6

Then you can divide the numbers so 27/9 = 3

Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0

Therefore the answer is just 3

The pie chart represents the proportions of how Henry spent the £720 he took on holiday.

Oksana_A [137]

Answer:

£124

Step-by-step explanation:

first of all, you're meant to add all the figures given on the pie chart, which is 29+137+58+62+74 and that will give you a total of 360 degrees

so, you say 360 degrees is equal to the total amount of money he spent, which is £720, what about 62 degrees

therefore, you just do (62×720)÷360

that will give you £124
