Question 30 a)

did anyone get 26 hours?

Got that

b) iv)

was it any value greater than 300?

Also nothing less than 0. because the height has to remain at 30m to match the question.

 

[paddydbarry]

i got 26 hours was the right??

 

[jayq94]

Would they deduct marks for not including anything under 0?

 

[Study-Guy]

i got 26 hours was the right??

yes

Question 30 a)

did anyone get 26 hours?

b) iv)

was it any value greater than 300?

Yep I got 26 hours and I said from 0 to -100 and 300 to 310 (I know now I should have just put 'greater than 300'

 

[jayq94]

24 a) (i) was it 1x10x10x10 = 1000

(ii) 1x1x10x10 = 1/120

 

[jayq94]

26. g) 15 full containers?

27.

b) 52.19cm?

c) 15cm?

 

[Study-Guy]

24 a) (i) was it 1x10x10x10 = 1000

(ii) 1x1x10x10 = 1/120

1x1x10x10 = 100. It was 1/100....Part 1 was right.

(ii) 1x1x10x10 = 1/120

Where did you get the 120 from???

b) 52.19cm?

c) 15cm?

26 g) yea 15 full WEEKS. and i dont understand what other questions you are asking.

Re: General Thoughts: General Mathematics

I remember watching a video about that cube on maths online

 

[jayq94]

Sorry that was a typo, i meant 1/100

27. b) was the perimeter of the sector question

c) was that annoying scale question for the cities 75km apart

Pretty sure 1cm was equal to 5k?

If we only put less than 0 would we still get a mark? I forgot about more than 300.

the perimetre question i did 13 + 13 + ( arc length formula with ø as 230 or ehat ever remained in the circle i dont have e paper here )


yes 15 cm for scale

Quite sure you got the perimeter question wrong. I think you did 230/360*pi*13 but then you have to add two lots of 13 because that previous calculation only does the circular part of the perimeter.

 

[Study-Guy]

27. b) was the perimeter of the sector question

230/360 x 2pie x 13 +13+13 = 78.19 (2dp)

c) was that annoying scale question for the cities 75km apart

15 cm is correct

 

[jayq94]

7500000/500000 = 15cm

 

[jayq94]

Perimeter of a circle - arc length formula

(2*pi*13) - (130/360 * 2*pi*13)

= 52. 16

 

[Study-Guy]

Perimeter of a circle - arc length formula

(2*pi*13) - (130/360 * 2*pi*13)

= 52. 16

you forgot the 26cm from the side of the sector.
