Answer:

Part A) x + y=125, y = x +45

Part B) 85 minutes

Part C) Not possible

Step-by-step explanation:

Given that Angela plays soccer and golf for a total of 125 minutes everyday.

Number of minutes she plays golf = x minutes

Number of minutes she plays soccer = y minutes

<u>Part A:</u>

Total time she plays golf and soccer is 125 minutes.

x+y=125 ...... (1)

Angela plays Soccer for 45 minutes longer than she plays golf i.e.

y = x+45 ....... (2)

The pair of linear equations are:

x + y=125, y = x +45

<u>Part B:</u>

Let us solve the linear equations (1) and (2):

Putting value of y from equation (2) into equation (1):

x+x+45=125 \\\Rightarrow 2x+45=125\\\Rightarrow 2x=80\\\Rightarrow x=40

Putting value of x in equation (2):

y = 40 +45 = 85\ minutes

Angela plays golf for 85 minutes daily.

<u>Part C:</u>

Given that

Angela spends 80 minutes on soccer.

Total Time = 125 minutes

\Rightarrow Time spent on golf = 125 - 80 = 45 minutes

Time spent on soccer longer than golf = 80 - 45 = 35 minutes \neq 45 minutes

Hence, it is not possible for Angela to have spent 80 minutes playing soccer if she plays for a total of exactly 125 minutes and plays soccer for 45 minutes longer than she plays golf.

So, the answers are:

Part A) x + y=125, y = x +45

Part B) 85 minutes

Part C) Not possible

Mr. Mendoza invests in five stocks. The table shows the growth in stock prices in dollars at the end of a trading day.
Morgarella [4.7K]

Answer:

The correct answer is C, as growth on stock E is bigger from the growth of stock B

Step-by-step explanation:

In order to resolve this problem, we must have in mind that the negative numbers are smaller when they are more distant from 0, and that positive numbers are bigger when they are more distant from 0. So, the biggest number of growth is the one that is more distant from 0.

The correct answer is C, as growth on stock E is bigger from the growth of stock B.

Drag tiles to fill in the blanks to complete the expression that could be used to predict the number of winners of a game. Tiles
ziro4ka [17]

Answer:

First blank - A)Total Number of Possible Outcomes

Second blank - B)Number of Winners

Step-by-step explanation:

The exact question is as follows :

We know that,

Probability of an event is equals to Total number of Favorable outcomes divided by Total number of outcomes

So,

P(event) = Number of favorable outcomes ÷ Total Number of Possible Outcomes

As we have to predict the Number of winners of a game

So,

P(Number of winner) = Number of winners ÷ Total number of Contestants

∴ we get

P(event) = Number of favorable outcomes ÷ Total Number of Possible  Outcomes

             = Number of winners ÷ Total number of Contestants
