Answers

Answer:

86: The basketball team scored 86 points

50: You deposited $50 in your bank account

8: A dolphin jumped 8 feet out of the water

-86: The elevation of Death Valley is 86 meters below sea level

-50: Eva withdrew $50 out of her account

-8: The temperature dropped 8 degrees

Step-by-step explanation:

In the bank situation you are losing or gaining something for example Eva withdrew $50 out of her account, since her bank account has less money in it its negative 50 and vice versa with depositing 50 in the bank account (adding more money to account makes it positive 50)

Last Season, A Lacrosse player scored 41 goals in 15 games, So far this season, the player has scored 24 goals in 9 games.

A. Does the player have a greater number of goals per game this season compared with last season?

(I think it is a no. If it is not no, explain)

B. Supposed the player plays in as many games this season as last season and continues to score at this season's rate. Write and solve A proportion to find the number of goals the player will score this season

Answers

Answer:

1.) No

2.) 40 goals

Step-by-step explanation:

Given the following :

Last season:

Games played = 15

Points scored = 41

Current season:

Games played = 9

Points scored = 24

Last season:

Goals per game = total points / number of games

Goals per game = 41 / 15 = 2.733

Current season :

Goals per game = total points / number of games

Goals per game = 24 / 9 = 2.667

Last season's goal per game is greater than that of current season.

Current rate = goals / games = 24/9 - - - (1)

Let points to be scored this season = y

Ratio of y to number of games played last season = y / 15 - - - (2)

Equate both

24 / 9 = y / 15

9 * y = 24 * 15

y = 360 / 9

y = 40

Answer:

A=no B=no

Step-by-step explanation:

in the first season you need to divide 41 into 15 to see how much he scored in 1 game which is 2.7333333333 continued

next you need to find second season which is 24/9 2.6666666666 continued

easy, 2.666666666 times 15 is too inacurate so do 24/9*15 which is 40 so the answer is also no

Angle of a straight line always sum up to 180 degrees
So what you should do is add the angles that are given to you and then subtract it from 180
Working:
100 + 20 + x = 180
120 + x = 180
x = 180 - 120
x = 60 degrees
