6.89(1.21) = 8.3369 rounds to 8.34 <==

or u could also do it this way...
6.89 + 0.21(6.89) = 6.89 + 1.4469 = 8.3369 rounds to 8.34 <==

Answer:

Option C is correct.

Step-by-step explanation:

Base Price of a roast chicken = $ 6.89

Increase in Price = 21 %

So,

New Price = Base price + Increased amount

                 =  6.89 + 21 % of 6.89

                 =  6.89+\frac{21}{100}\times6.89

                 =  6.89+\frac{144.69}{100}

                 =  6.89 + 1.4469

                 =  8.3369

                 =  $ 8.34 (to nearest cent)

Therefore, Option C is correct.

My soccer team has 16 players. I have to choose a starting lineup of a goalie and 10 regular players (the regular players are in
ASHA 777 [7]

Answer:

3003

Step-by-step explanation:

We want to find out how many ways we can choose 10 players among 15 players (since the goalie is not interchangeable)

The number of different lineups you can have can be found by using combination:

^{15}C_{10} = \frac{15!}{(15 - 10)! 10!}\\ \\= \frac{15!}{5! * 10!} \\\\= 3003

There are 3003 different lineups that can be chosen.

Solve this system of linear equations.separate the x- and y-value with a comma. -6x=-4-y -7x=-22+y.
scZoUnD [109]

Answer:

(2,8)

Step-by-step explanation:

Add them together to get rid of the y.

-6x = -4 - y

-7x = -22 + y

=

-13x = -26

Then solve for x.

-13x/-13 = -26/-13

x = 2

Now plug in the x value into either equation and solve for y.

-7(2) = -22 + y

-14 = -22 + y

-14 + 22 = -22 + 22 + y

8 = y

So...

x = 2

y = 8

(2,8)
