PLEASE ONLY TYPE THE NUMBERS IN THE ANSWER. NO LABELS. ROUND TO NEAREST TENTH.

Area =

Answers

Answer:

Length = 208in

width=160in

Area=33280in²

Step-by-step explanation:

8ft is equal to 96inches thus ratio is 3:96

length= 6.5×96/3

=208in.

width=5×96/3

=160in.

Area=l×w

=208×206

=33280in²

In a football (soccer) league, teams receive 3 points for a win (W), 2 points for a tie (T) and 1 point for a loss (L).

a) Write an algebraic expression to represent a team’s total points using the variables listed above.

b) The Thistletown Black Scots’ record for the season was 5 wins, 2 ties and 3 losses. Using your
expression, find the Black Scots’ total points.

c) The 10–game season ended with the Black Scots tied for first place with the same number of points as the Mustangs however their records weren’t the same. What was the Mustang’s record?

Answers

a) Total points = 3W + 2T + 1L

b) (3*5) + (2*2) + (3*1)
15 + 4 + 3 = 22
The Black Scot’s total points were 22

c) so, Wins + Ties + Losses = 10 because there were only 10 games played. but we also have to remember that we only can have 22 points. I just randomly plug in numbers until I get what I am looking for.

so I did 4 wins, 4 ties, and 2 losses. this is a total of 10 games, and the points equal 22. we just plug those values into our first equation:
(3*4) + (2*4) + (1*2)
12 + 8 + 2 = 22 points

1.- En la cooperativa escolar se vendieron 296 refrescos en total. Si los refrescos chicos vendidos fueron el triple de los
medianos. ¿Cuántos se vendieron de cada uno?​

Answers

Answer:

222 small ones and 74 middle ones

Step-by-step explanation:

The computation is shown below:

Let us assume medium ones be x

so the small ones be 3x

And, the total is 296

So, the equation is

x + 3 x = 296

4x = 296

Medium ones = x = 74

And, the small ones is = 3 × 74

= 222
