Answer:

1. 5417.412

2. 401.13

Step-by-step explanation:

1. First, rewrite

$5\times 10^3+4\times 10^2+1\times 10^1+7\times 10^0+4\times \dfrac{1}{10^1}+1\times \dfrac{1}{10^2}+2\times \dfrac{1}{10^3}$

$5\times 1000+4\times 100+1\times 10+7\times 1+4\times 0.1+1\times 0.01+2\times 0.001$

So, this is

$5000+400+10+7+0.4+0.01+0.002\\ \\=5417.412$

2. First, rewrite

$4\times 10^2+1\times 1 \dfrac{1}{10^1}+3\times \dfrac{1}{10^2}$

$4\times 10^2+1\times 1 +1\times \dfrac{1}{10^1}+3\times \dfrac{1}{10^2}$

This is

$4\times 100+1\times 1+1\times 0.1+3\times 0.01$

So, this is

$400+1+0.1+0.03\\ \\=401.13$

In a running competition, a bronze, silver and gold medal must be given to the top three girls and top three boys. If 15 boys an

denis-greek [22]

Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

$Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455$

$Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4$

Total number of possible results:

$results = 4*455\\results = 1820$

1. a car travels 363 miles in 2 hours and 45 minutes. Work out the average speed.

Mazyrski [523]

1. Average Speed is distance divided by time. So 363 divided by 165 is 2.2

2. For number 2 I am not sure if there is a missing piece to your question but the car has travelled 72 miles in 220 minutes
