Lana and Emily are playing a competitive word game. Whoever plays all of their tiles first gets to add the value of their word plus the total value of all of their opponent’s remaining tiles to their score. Also, the opponent must subtract the total value of all of their tiles from their score.Suppose that the current score is: Lana 324, Emily 358. If Lana’s last word is worth 7 points, how many points does she need Emily to have in her hand in order to win?

Suppose that the current score is: Lana 324, Emily 358. If Lana’s last word is worth 7 points, how many points does she need Emily to have in her hand in order to win? ___________ points

Hint: If Emily had 5 points in her hand, by how much would the difference between the player’s scores change?

Answers

Answer 1

Answer: Lana gets the 7 points so she ends up with 331. She will then be 358-331=27points behind Emily. She needs to win, so there needs to be 1 more than 27 points of change in the score, or 28 points. Emily's hand value is added to Lana's and also subtracted from Emily's so her hand is worth twice the value as the amount. (If the hand is worth 10 points, it changes the scores by 20 points). Thus, we only need half of the 28 points of change for Lana to win. The answer is 14 points.

Mark tossed six balls while playing a number game. Three balls landed in one section, and three balls landed in another section. His score is greater than one hundred thousand. What could his score be?

Answers

Given that Marktossed six balls while playing a number game and that three balls landed in onesection, and three balls landed in another section.

Since his score isgreater than one hundred thousand, that means that three of the balls landed in the section of 100,000 this will make the score 300,000.

If the other three balls, landed in the section of 10,000, this will make the score for the 3 balls to be 30,000

Therefore, his score will be 300,000 + 30,000 = 330,000

30 POINTS The graph shows how many inches above the ground, y, the valve on a rotating tire is for a given number of seconds x.

How many degrees is the tire turning every second?

Enter your answer in the box.

Answers

Answer:

180 degrees per second.

Step-by-step explanation:

We have been given a graph that shows the distance covered by a tire or angular velocity of a tire with respect to the number of seconds (x).

Since we know that a tire is a circle and the measure of all the angles of a circle equals to 360 degrees.

We can see from our given graph that the tire completes one rotation in 2 seconds (2.5-0.5), so the distance covered by tire in two seconds will be 360 degrees. This means that the tire turns 360 degrees in each 2 seconds.

$\text{Degrees turned by tire in 2 seconds}=\frac{360^o}{2\text{ seconds}}$

As we are asked to find the degree change by tire per second so we will find the unit rate such that we will have 1 in our denominator. By dividing our numerator and denominator by 2 we will get,

$\text{Degrees turned by tire in every second}=\frac{180^o}{\text{ second}}$

Therefore, the tire is turning 180 degrees per second.

It takes 2 seconds for the tire to make a full revolution. This is evident from the plot - the curve has a period of length 2.

A full revolution of the tire is a turn of 360 degrees.

So the tire turns at a rate of (360 degrees)/(2 seconds) = 180 degrees/second.
