There are eight teams in a league. I’m how many ways can the teams finish first, second, and third?
jolli1 [7]

Answer:

There are 336 ways can the teams finish first, second, and third

Step-by-step explanation:

Total no. of teams = 8

First prize is given to one of the 8 teams

So, no. of teams left for second prize = 8-1 =7

Second prize is given to one of the remaining 7 teams

So, no. of teams left for third prize = 7-1=6

So,the teams finish first, second, and third in no. of ways =8 \times 7 \times 6

The teams finish first, second, and third in no. of ways = 336

Hence there are 336 ways can the teams finish first, second, and third

Gisele has $5.90 in quarters and nickels. If Gisele has 16 more nickels than quarters, how many quarters does she have? [I don't
Elena-2011 [213]

Answer: There are 17 quarters.

Step-by-step explanation:

Let x = Number of quarters and  Number of nickels =x+16

∵ 1 nickel = $0.05, 1 quarter = $0.25

value of x quarters = 0.25 x

value of x+16  nickels = 0.05(x+16)

Then, as per given,

0.05(x+16)+0.25 x= 5.90 \\\\\Rightarrow\ 0.05x+0.8+0.25x=5.90\\\\\Rightarrow\ 0.30x=5.9-0.8\\\\\Rightarrow\ 0.30x=5.1\\\\\Rightarrow\ x=\dfrac{5.1}{0.30}=\dfrac{51}{3}\\\\\Rightarrow\ x=17

Hence, there are 17 quarters.
