To get the total number of games possible, we will use the combination formula. 
Total number of games :  _{10}C_{2} = 45

Total of 45 games in the whole tournament.

Meanwhile, if there would be boy-versus-boy, we will have _{5}C_{2}
The answer is 10. 

The fraction for boy-versus-boy game will be 10/45 or 2/9 when simplified.

If Ruby plans on making 4 batches of pancakes, how many combined cups of powdered milk and whole wheat flour does she need?
Trava [24]

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.

Given the <em>quantities</em> of powdered milk and whole wheat to prepare a batch of pancakes, we can determined the <em>total</em> amount of each ingredient by simple rule of three:

Powdered milk

x = 4\,batches\times  \frac{1}{4}\,\frac{cups}{batch}

x = 1\,cup

Whole wheat

y = 4\,batches \times \frac{3}{2}\,\frac{cup}{batch}

y = 6\,cups

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.

A principal of $4700 was invested at 4.75% interest, compounded annually.
Kitty [74]

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

y = P(1 + r/n)^nt

Where

y = the value of the investment at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount invested

From the information given,

P = $4700

r = 4.75% = 4.75/100 = 0.0475

n = 1 because it was compounded once in a year.

Therefore, the exponential function showing the relationship between y and t is

y = 4700(1 + 0.0475/1)^1 × t

y = 4700(1.0475)^t
