Maths year 11

Yes done.

And now I add 10/24 3 times?

oKay hold on.

You're supposed to multiply 1/4 and 1/6 not add them. First you do that 3 times and THEN you add up the results.

That equals to 3/24

where did you pull that from??

yeah i got a bit distracted, you got it right and you can simplify that fraction

Yusss 1/8

On this question what do they mean compare?

As it give differences and write it out?



Posted from TSR Mobile

Not quite sure. I'd assume you need to find the mean of each set of data, and maybe do something with a box plot diagram and arrive at some sort of conclusion like "boys on average weight more" or something. Look at the mark scheme if you're unsure. This question is not specific enough for me.

Oh okay

How do I do B please and is a correct?

Yes A is correct and for the second one you are doing the same thing except you are looking for a year while you know the money at the end.

So $400 \cdot 1.03^n = 475$

The answer I for was 5 and half

So after 6 years then.

So after 6 years then.

Heyaa can you check the above please X

First one is correct but for the second one you found the amount that would be deducted from total price as a result of the discount - so you didn't find the total amount paid.

Oh i thought it was 15% of each lesson?

Posted from TSR Mobile

15% off each lesson. Difference between of and off.

So you take off 15% from the total price which would be 100%, so you are finding 100%-15%=85% of the normal price.

So I do 23*47 first

And then find 15%

Posted from TSR Mobile

That is correct, depending on what kind of approach you are taking.

What would we find if we did this?
