Hi


Nid help with this question.

:thankyou:
Hi. I can't see the picture clearly. Is it 63 and 72?

Factors of 63: 7x9
Factors of 72: 8x9
The common factor is 9. That means the common length of A and B is 9cm.

So breadths are 7cm and 8cm. Sum is 15cm, side of square C.

Area of C=15x15 =225 sq cm#

Perimeter = 15x4 + 9x2 = 78cm#

Hi,


Anyone can help me with this question:-

Nicole bought a chicken burger and a salad for $4.70. Sarah bought 7 chicken burgers and 3 servings of salad for $21.70. Find the cost of the salad.

Many thanks!!

Sharmum
3 burgers + 3 salad = 3*4.70

Therefore 4 burgers = 21.70 - (3*4.70)
One burger = ...
One salad = 4.70 - one burger

Hi,

I need help on this question ;
The mass of floir in container A was 1/3 of the mass of flour in container B. After 2kg of flour in container A and 9kg of flour in container B were used, the mass of flour in container A was 1/2 of that of container B. What was the total mass of flour in container A at first?
Thank you ~

Answer should be 5kg. Crude representation below.

A. -- 1u
B -- 3u

A -- []2kg (This is 1u)
B -- []2kg []2kg []2kg (3u)

Looking at B, since 9kg was used before A become half of B, 9-6 = 3.
[] is 3kg.
Original quantity in A is 3+2 = 5kg.

Thank you so much. I can explain to my gal now.

Sniper Angel:
The number of dogs in a pet shop was 3/10 of the number of cats & hamsters. There were 49 more cats & hamsters than dogs. After some hamsters were sold, the number of dogs was 1/2 of the number of cats & hamsters. How many hamsters were sold?

Dog. : H&C
3. : 10. (At first) 10u-3u->49. 1u ->7
(21) : (70)


1. : 2. (In the end) [since there is no change in Dogs, make the before and after change the same]
=> 3. : 6.

Change in H&C -> 10u-6u -> 4u.-> 28

28 hamsters were sold.
