49×12= 588
1. 50×10=500
2. 50×10+2= 502 
3. 50×12-12= 588
4. 50+12-12=50

Another way to write 49×12 is 50×12-12

when measuring time 8 concerts are approximately equal to 6 symphonies how many concerts are equal to 28 concerts how many conce
tatiyna
Lets answer this:-

1st lets divide to see how many times 28 goes in 8. And then we will multiply....

28 ÷ 8 = 3.5

Now lets multiply to see how many symphonies are equal to 25 concerts. Lets do it:-

3.5 × 6 = 21

So, 21 symphonies are equal to 28 concerts. 

Lets divide to see how many concerts are equal to 42 symphonies and the multiply to get our final answer. 

42 ÷ 6 = 7

7 × 8 = 56.

So, 56 concerts are equal to 42 symphonies.

Hope I helped ya!!

Flying against the wind, an airplane travels 4340 kilometers in 7 hours. Flying with the wind, the same plane travels 3120 kilom
Over [174]

The rate of the wind is given to be 210 the rate of the plane in mid air is given as 830

<h3>Howe to solve for the rate of the plane and wind</h3>

In 7 hours the kilometer traveled =  4340

P + W = 4340/7

= 620

P-W = 3120/3 hours

= 1040

2p = 1040 + 620

= 1660

p =830

W = 1040 - 830

= 210

Hence the rate of the wind is given to be 210 the rate of the plane in mid air is given as 830

Mehvish buys 1/2 kg carrots, 3 kg potatoes, 2 kg onions and 1 1/2kg of chicken.
ozzi

Answer:

The amount of change will be £7.99

Step-by-step explanation:

Here, we want to calculate the amount of change that Mehvish should get

1/2 kg carrots at 50 p per kg will be;

1/2 * 50 = 25 p

3 kg potatoes at 64 p per kg will be

3 * 64 = p 192

2 kg onions at 42 p per kg

2 * 42 p = 84 p

1 1/2 kg chicken at £6 per kg will be:

since £1 is 100 p

1.5 * 6 = £9 (9 * 100 p = 900p)

since £1 is 100 p

£20 will be;

20 * 100 = 2,000 p

So let us make the subtraction as follows;

2,000- 900 - 84-192 - 25 = 799 p

In pounds, this is divided by 100

we have this as 799/100 = £7.99
