The post Which expression represents the algebraic phrase “nine times a number plus thirteen”? A. 9 – y + 13 B. 9 + y – 13 C. 9y + 13 D. 13y + 9 appeared first on EduHawks.com.

]]>**Answer: The correct option is (C) 9y + 13.**

**Step-by-step explanation: **We are given to** select the expression** that represents the following statement :

“nine times a number plus thirteen”

Let the number be represented by y.

**Then, nine times the number is written as follows :**

Since we are to add 13, **so the final expression is given by**

**Thus, the required expression is**

**Option (C) is CORRECT.**

The is the concept of algebra, the weight of the spring can be modeled by the equation;

w=0.9sqrt E

where;

=energy in joules;

thus the weight of the spring when the energy is 12 j will be:

w=0.9sqrt12

w=3.18 g

As far as I understand, you have to write possible conclusions and show how motivated you become after reading this excerpt. You can write something like this : 1) My journey through this lesson enabled me to learn that I am capable of making and doing new things, the things which I have never experienced before. I also can see that my potential is quite enough to bring all the learned things in the future. And even though life can prepare a tough situations, I can accept this challenge and make a profit out of life obstacles because my knowledge is my weapon.

2) It made me realize that every person must take life challenges seriously. People also have to recognize these challenges in order to be prepared for the unexpected future. So now I understand that I should never give up and always keep in mind that there are always many solutions and the only thing that people need — is a little time to find them.

3) I, therefore, commit to be strong and faithful to myself and towards other people. Accepting personal challenges help one to be a good person, so I am ready to assume such a responsibility. With this realisation I can inspire myself for new steps towards the future. It will make me feel confident wherever I am and thus can lead me to a personal success.

]]>The post Tina can paint a room 1.5 times faster than Joey can. If they work together, they can paint a room in 6 hours. How long would it take the slower person working alone to paint the room? appeared first on EduHawks.com.

]]>To answer this problem, let us define that:

x = amount of time Joey can paint a room in hours

1.5 x = amount of time Tina can paint a room in hours

Each person can complete 1 job in the specified amount of

time.

1 job / x hours = rate of Joey

1job / 1.5 x hours = rate of Tina

By adding the two, they can paint the room (1 job) in 6

hours. Therefore:

(1 / x) + (1 / 1.5 x) = 1 / 6

Multiplying whole equation with 6 (x) (1.5 x):

6 (1.5 x) + 6 x = x (1.5 x)

9 x + 6 x = 1.5 x^2

Dividing both sides with x:

15 = 1.5 x

x = 10 hours

Therefore the time it will take Tina, the slower person, is

1.5x = 15 hours

**ANSWER: 15 hours**

]]>**Answer:**

The correct options are:

- Four families said they ate out twice the previous week.
- One family said they ate out 5 times the previous week.
- The median best represents the data set.

**Step-by-step explanation:**

We are given a data set as:

4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1

On arranging this data set in the frequency table we get:

Number of times they went for dinner Number of families

0 2

1 3

2 4

3 1

4 2

5 1

6 1

- Hence, the range of the number line is between 0 to 6.

- Also there are 4 dots above 2.

Hence, Four families said they ate out twice the previous week.

- Also there is one dot above 5.

Hence, One family said they ate out 5 times the previous week.

- The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.

Hence, the data set is not symmetrical.

- Also we know that the median of the data is the central tendency of the data and always best represents the data.

Hence, The median best represents the data set.
