    Hi i was just signing on but i have a question about the homework Question 7 (iii), I think i did the first two parts correctly but now i don’t know what to do in this part. The page number is 55.

  • Mrs Tibble

    Hi Asha,

    When you subtract in part (ii) you’ll get 9n = something

    The last bit, when you divide by 9 to find n is the answer to part (iii)

    Thank you i think i have it now
    see you tomorrow

  • Becky

    Hi Mrs Tibble,

    Sorry to pester you on the weekend, ive done all the homework apart from question 7 ex 10I pg55. I am so confused. i think once i know how to do part a i will get part b but i have no idea how to do part a. Either im being really stupid or ive forgotton how to do it. please help! :) thankyou x

    Hi Becky,

    Write 1.7 in fraction format by putting it over 1, then adjust it so that you don’t have a decimal within a fraction.

    8-)

  • Becky

    Thankyou so much, im so silly, i completely forgot. LOL. I think i understand it now. This blog is so helpful. x :P

  • Mrs Tibble

    Spread the word!! 8-)

    Hello, I am very confused on the 10i homework you set us. I can’t remember how to do question 3 and also how to do question 6h or 6g. I did 6g but I was confused. :)
    thanks.

  • Mrs Tibble

    Hi Rosie,

    For Q3 use your calculator to do the division sums:
    2 divided by 9, 1 divided by 5, etc

    In 6g
    let x = 0.06363636363……………
    Because the repeating part is 2 digits, multiplying by 100 will make the repeating bits match ie line up in the same columns:
    100x = 6.36363636363……………
    Now subtract, and the matching parts will disappear leaving you with an exact simple sum
    99x = 6.3
    Divide by 99 to get x, and sort it out so that you get rid of the decimal within the fraction.

    Does that help? Look in your notes at what we did in class too.

  • Edie Lippa

    hi mrs tibble
    im a bit confused with question 7b ii and iii
    i cant remember how to take away 17.77….. from 1.7…. because when i do it becomes 16!!!!!!!!
    and that doesnt seem right!! unless it is but im not sure
    thank you .

  • Mrs Tibble

    Hi Edie,

    First of all you need to get your subtraction the right way round!!!!
    You are taking 1.777777……. away from 17.7777777777777777………..
    All the decimal 7s will disappear and you get 16, so you are correct.
    Therefore 9n=16
    Divide by 9 to get n (which is the answer to part iii)

  • Edie Lippa

    yay okay thank you mrs tibble thats great :)

  • Asha Williams

    Hi Mrs Tibble, i don’t get question number 1 of tonights h/w (p8 ex.2H).First of all it says find the weight does it mean find the height?
    And if so how do i find the height, i tried to do :
    5×0.90 (because I thought you had to decrease) for the first one and got 4.5 and then it kept on geting higher. What am I doing wrong?

  • Edie Lippa

    yeah im confused at that as well!!!!

  • Mrs Tibble

    Hi Asha,
    Yes, I’m sure it should be height lol!
    The plant is growing, not shrivelling up, so the multiplier will be >1. 100% + 10% = 110% so the multiplier is 1.1.
    You should be OK now :-)

  • Asha Williams

    Thank you see you tomorrow.
    :D

  • Rosie

    Hello Mrs Tibble,
    I completely forgot to see you today looking for catch up work!
    I will do the homework but I do not have my book here so I can’t get the ex. number. Sorry!
    I’m sorry its going to be late just thought you should know.
    :/

  • Mrs Tibble

    Rosie,
    It’s Ex 2H Q1-5

  • Edie Lippa

    hello mrs tibble
    i really dont understand question 3 on the homework!!!!

  • Mrs Tibble

    Hi Edie,
    Can you give me the exercise number please.
    JT

  • Mrs Tibble

    OK Found it! Ex 8A?
    Draw a kite – you should be able to do that!!
    Corners are EFGH. Draw in the diagonals – call the crossing point something, then use the symmetry and what you know about kites to work out which triangles on your diagram are congruent (and why).

  • Edie Lippa

    hello mrs tibble
    i was just wondering for the test tomorrow
    i have revised the straight line graphs but i havent revised the circles we did on tuesday! i was wondering if i should?
    thank you

  • Mrs Tibble

    Hi Edie,
    No, the test is just on straight line graphs.
    See you tomorrow
    :-)

  • Mrs Tibble

    TEST RESULTS :-D

    All grades B and above.

    Well done everyone 8-)

  • Maddy Ferns

    hi mrs tibble
    i dont understand the circle theorems homework, i’ve done a few of the questions but cant do the rest
    its ex 7c qu 2 and 6 and the other excersice that i cant to

  • Mrs Tibble

    Hi Maddy,
    Hope you’ve had a good half term holiday.
    Ex 7C is all about angles in the same segment being equal. Draw the chord in if it helps.
    In 2c you’ll need to use the special angles between parallel lines as well. Look it up if you can’t remember – it will be somewhere on the disc (or Google!)
    Was 7D the other exercise? This is on cyclic quadrilaterals and general props of triangles (180 deg) and quadrilaterals (360 deg).
    Does that help?
    JT

  • Maddy Ferns

    yeah, thanks. il do it again

  • Mrs Tibble

    Have fun 8-)

  • Becky

    Hi Mrs Tibble,

    Claudia, Asha and i are not quite sure how to do the homework. We know we have to explain why the adverage is not 60 mph but we dont know why 60mph is not the adverage. LOL. Please can you help us??

    Thankyou xx

  • Becky

    Hi Mrs Tibble,

    Asha, Claudia and I dont understand the homework. We know we have to explain why the average speed was not 60mph but we dont know why it was not 60mph. LOL :D Please can you help us?? Thankyou xx

  • Mrs Tibble

    Try making up a distance value so that you can work with real numbers. You don’t actually need one, but it might help you. Actual value doesn’t matter as it cancels out in the end.

  • Becky

    Merry Christmas Mrs Tibble!! HO HO HO ;) x

  • Mrs Tibble

    Happy Christmas to you too Becky. Are you working hard? ;-)
    See you soon!
    JT

  • Becky

  • Mrs Tibble

    That’s what we like to hear ;-)
    I look forward to marking your papers then!
    Have fun.

  • Becky

    Hi Mrs Tibble, sorry to be a pest, it doesnt say straight line graphs on the revision list, do we still need to know them?? And also whats inverse square law graphs?? :P thankyou xx

  • Mrs Tibble

    Hi Becky,
    Straight line graphs are part of this term’s work so, yes, you need them.
    Inverse square law graphs are y=1/x^2 curves.

  • Becky

    oh okay,i was just checking :) i didnt know they were called that. Thankyou x

  • Rosie

    Hello, I’m really sorry I missed the lesson. What was the homework set?

    The homework is from the blue HW book:
    Ex 4G Q3
    Ex 4H Q3 + Q5
    Ex 4I Q3 + Q5
    You’ll need
    Vol of a pyramid = (area of base x height)/3

  • Asha Williams

    Hello Mrs Tibble I really don’t understand the maths i tried to draw the cube and i drew a cube but not with the correct coordinates because i couldn’t figure out the paper, that was Q.4.

  • Mrs Tibble
