hi its Jenijo I forgot how to do BD1.2 E F G and H also BD1.3 3 (a)
Well done for asking and revising Jenijo. They are both the same type of question, just laid out a different way.
This is sharing a quantity using a ratio. You have a note on it but all you do is add the parts of the ratio and use that to find the value of 1 part.
ie. if i had a ratio of 3:2:5 then there would be 3+2+5 = 10 parts.
From there you would divide by 10 to find the value of 1 part and so on.
Let me know if that helps. If not then we can discuss tomorrow.
hi need help on bd1.3 question 7
Hi Kayleigh. I’m sorry for the late reply. I have only just this message. I will try and help you tomorrow in class. Otherwise i will post an answer on here.
hi i got a question in bd1.6 Q1 b) and c) what is the origin?
The origin is the centre of your axes.
ok thank you
Hi see for the revision booklet for BD3.6 it says draw a Cartesian Diagram. I was just wondering what a Cartesian Diagram is.
Its just a set of axes. A coordinate grid.
Okay thank you.
Hi,is our revision going to be marked?
I can mark some of it for you but I couldn’t mark every single piece of revision for the whole class. It’s more important for you to find areas you need help on and we can work through them.
Use your notes and examples.
Okay thank you, so we only do parts we are not sure on
Have a look through the whole thing but please don’t waste time doing a load of questions that you find easy.
Find things you want help with and ask on here or in class Teigan.
Good luck and let me know if I can help tomorrow.
Hi, I’m stuck on exercise 4 question 2 for Monday, Can you help please?
Abby i need to know what section??
It’s not the revision it’s homework
Ah i see Abby. I’ll have a at the booklet later.
If I don’t have it then i can talk to you tomorrow.
Thanks for letting me know.
Abby i dont seem to have to sheet at home, so sorry.
We can go over it tomorrow, it’s an extremely positive process you have gone through though. Thanks for letting me know and in future, continue to use the Blog.
hi how do you do a scatter graph again
You must draw a line through the piints but its doesnt need to touch every point. AND it doesnt need to start at zero.
The line should be an average of the trend (the direction of most of the points)
Okay thank you, I don’t understand how to do the Cartesian diagram for the homework and revision
Teigan, cartesian diagrams are just x and y axes. So plotting points, find the coordinates using the equation and plot the points.
Okay thanks I’ll try
Ask for more help here if you need it. Otherwise I can help in class tomorrow.
Okay thanks, I’ll try it and if I can’t I’ll ask tomorrow
Hi, I was just going in over the homework and revision booklet and I have completely forgot how to do ratio, like in the homework booklet Exercise 2- question 4? I was wondering what was a easy way to understand it??
Hi Melissa. I dont actually have the honework booklet at home.
Can you tell me a question from the revision sheet and that way i can help tonight.
Okay, it’s main it all kinda, like bd1.3 Q1 and 3
It’s just getting all jumbled up?
hi i am not sure what to do on bd3.7
Set up a table with 2 rows.
The top row is for the x values and the 2nd row is for y values. (See notes)
You will be given a formula eg. y=3x + 2 and this will allow you to find y values by substituting the x values into the formula.
Ar the end the x value is the x coordinate and the y value the y coordinate.
Hi i dont know how to get bd2.2 q2 b and c
Find the total number of people first.
Then create a fraction woth the rangers amount on top, change it to a division and use the decimal answer to get to a percetrage. Either by multiplying by 100 or simply using your knowledge on decimals/percentages.
eg. 4/16 = (4 divided by 16) x 100
= 0.25 x 100 = 25%
I’m confused with BD5.1
Q2 a) 7% of £25
I know I need to make it into a fraction I just forgot how.
There are 2 ways to do that Kirsty
Either divide 25 by 100 then multiply the answer by 7
0.07 x 25
hi it is chloe can you help me with
At a school assembly there are 432 pupils. The ratio of boys to girls is 5 : 7.
(a) How many boys are at the assembly?
(b) How many girls are at the assembly?
Add 5 and 7 to get 12 parts
Then divide 432 by 12 to find 1 part.
Once you have 1 part, you can multiply to find 5 parts and 7 parts.
i am doing some revision, can you help me with exercise 12 question 1 in homework booklet. thank you
Certainly, there are a few ways to find 15%
Find 10% by dividing by 10, then half that value to get 5% and add the two values together.
You can use a similar technique to get 20% also but obviously instead of halving 10% you double the value.
Alternatively you can divide by 100 and then multiply by 15.
And finally you could simply multiply by 0.15 which is the decimal equivalent of 15%.
Don’t go too far ahead in the booklet Chloe, it is far more important to mend the areas of difficulty highlighted by the test.
so for the first way of doing it would you do 2 divided by 10% then half the answer and add together?
I wont go to far ahead I just want to do some revision as I didn’t do to well on my test.
No Chloe, we haven’t decided on how to do that in class as yet. Leave that question and we can discuss it in class.
Focus on Ratio etc from test. There is no point in trying new stuff as yet.
It’s good to see you showing initiative but make sure you do it in good time going forward. (ie. prior to a test)
okay will do, I think I have an idea on how to work it out but I will leave it out and go onto ratios thank you anyway?
I have put my maths stuff in my locker at the end of the day forgetting we had to get our parents to sign the evaluation,will I just hand it in on Thursday?
Yeah no problem.
