ANSWER BOTH QUESTIONS FOR BRAINLIEST TY :)

Answer:

Step-by-step explanation:

180-90

90

This gives us the measurement of 51+x.

90-51

39

This is x as well as the angle that is across from it.

x+90=y

39+90=129

y=129.

to find the last angle, we add 90 to 51. This gives us 141.

So, now we add up all of the angles to double check everything. If they all add up to 360 then we are correct.

39+39+51+90+141=

360.

This means that we have solved everything correctly and that these are the correct answers.

I know that this is really confusing but the answers that you need are at the top so hopefully this helped!

Mrs. Smith asked her students to make observations about the histogram, Annual Rainfall of Cities.

The water level in a glass decreases 0.4 cm each hour due to evaporation. At the beginning of the experiment, the water level is 12.6 cm.

Let x represent time, in hours, elapsed since the beginning of the experiment and let y represent the water level, in centimeters.

Part A

Construct a linear function, using x and y from above, that determines the water level at a given time, in hours, after the experiment begins.

Part B

How many hours does it take for all of the water to evaporate?

A. [3, 4]
B. [1, 2, 5, 6]
C. [1, 2, 3, 4, 5, 6]
D. [5, 6]

2. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
A. Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.
B. Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.
C. Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.
D. Her probability of winning is an independent event because it depends on the results of her friends’ rolls.

3. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
