Answer:

The coach can do this in 3,003 ways

Step-by-step explanation:

Here, the coach needs to select a team of 5 from a total of 15 players

Mathematically, the number of ways this can be done is simply 15 C5 ways

Generally, if we are to select a number of r items from n items, this can be done in nCr ways = n!/(n-r)!r!

Applying this to the situation on ground, we have;

15C5 = 15!/(15-5)!5! = 15!/10!5! = 3,003 ways

<u>Answer:</u>

(i) Total cost of the flat is Rs. 540000.

(ii) Expenditure incurred on labour is Rs. 150000

<u>Step-by-step explanation:</u>

According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.

(i) The total cost of the flat is represented by the total 360° in the pie chart.

∴ Using unitary method

75° represents Rs. 112500

⇒ 360° represents = \frac{112500}{75}  ×  360

                                = Rs. 540000

∴  Total cost of flat = Rs. 540000

(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:

75° represents Rs. 112500

⇒ 100° represents =  \frac{112500}{75}  ×  100

                               = Rs. 150000

∴ Cost of labour = Rs. 150000

Serggg [28]

Answer: C

: Miriam multiplied correctly, but her third fraction should be .S

Step-by-step explanation: Miriam used the unit conversation upside down. The 7000 g should have been multiplied by 1oz/28.35g

The grams cancel and the division of 7000 be 28.35 results in 246.91 oz Round to 252oz.

Alternative: 7kg (2.21 lb/kg)(16oz/lb)=252.5oz
