How many numbers are 10 units from 0 on the number line?

Answers

it would be 10 to the right when you add from 0
On a real number, the number 0 is at the middle of it. And from that point, you can go two ways, the negative direction or the positive direction. So, you can go 10 units to the left, which is the negative direction, or 10 units to the right, which is the positive direction.

So, there are 2 numbers that are 10 units away from 0.

A student got a grade of 85% on a text in which she answered 3 questions incorrectly. How many questions were on the test?

Answers

Alright, we have to ask ourselves "How much of 100% is one question worth?"

To find this, we must first find out how much was taken off of 100% to get 85%.  In terms of math, this can be put like this:

100% - X = 85%

Now, we solve for X.

100% - X = 85%

Add X to both sides.

100% = 85% + X

Subtract 85% from both sides.

100% - 85% = X

Subtract.

15% = X

This means that 15% was taken off of 100% to get 85%.  In other words, 3 incorrect questions are equal to 15% of the final grade.  In terms of math, we can put it like this:

3 = 15%

Now, let's go back to the first question we asked at the beginning.

"How much of 100% is one question worth?"

To find this, we need to make 3 become 1 in the equation 3 = 15%.

3 = 15%

Divide both sides by three.

3/3 = 15%/3

Divide.

1 = 5%

This means that 1 question is worth 5% of the grade.  With this information, we can find out how many questions it takes to get 100% of the grade.  To do this, we need to make the 5% become 100%.

1 = 5%

Multiply both sides by 20.

20(1) = 20(5%)

20 = 100%

This means that there are a total of 20 questions on the test.

By interpreting the student's grade of 85% and knowing that 3 questions were answered incorrectly, we can infer that the test consisted of 20 questions in total.

To calculate how many questions were on the test, we first need to establish the relationship between the number of questions answered incorrectly and the student's overall percentage score. If the student got an 85% on the test, this means they answered 85% of the questions correctly. With 3 questions answered incorrectly, we can assume that these incorrect answers account for the remaining 15%. To find the total number of questions on the test (let's denote it as x), we set up a simple equation:

0.15x = 3

Solving for x yields:

x = 3 / 0.15

x = 20

Therefore, the test consisted of 20 questions in total.

An investment earns 6% simple interest. What amount of principal is needed to have $3000 after 5 years? Round your answer to the nearest cent.

Answers

The principal amount needed to have $3000 after 5 years with 6% simple interest is $10,000.

To find the principal amount needed to have $3000 after 5 years with 6% simple interest, we can use the formula for simple interest:

Simple Interest = Principal * Rate * Time

where Rate is the interest rate as a decimal, and Time is the time period in years.

We can rearrange this formula to solve for the Principal:

Principal = Simple Interest / (Rate * Time)

In this case, we want to find the Principal that will yield $3000 after 5 years with 6% simple interest. Therefore, we have:

Simple Interest = $3000

Rate = 0.06

Time = 5 years

Plugging these values into the formula, we get:

Principal = $3000 / (0.06 * 5) = $10,000

Therefore, the principal amount needed to have $3000 after 5 years with 6% simple interest is $10,000.

If a student received a score of 75% on a text in which 96 questions were answered correctly, how many questions were on the test?

Answers

X=128
96/x=75/100
YOU CAN CROSS MULTIPLY

Final answer:

To find the total number of questions on the test, we divide the number of correctly answered questions (96) by the score as a decimal (0.75), which gives us 128 questions in total.

Explanation:

To determine the total number of questions on the test, we can use the given information that a student received a score of 75% by answering 96 questions correctly. The percentage score represents the fraction of the total number of questions that were answered correctly. So, if 96 questions were 75% of the total, we can find the total number of questions (T) using the following equation:

75% of T = 96
0.75 × T = 96
T = 96 / 0.75
T = 128

Therefore, there were 128 questions on the test.

Why is indirect compensation important to recruiting and retaining employees?

Answers

it is important because the quality of an organization's people is always is an essential ingredient of strategy execution---- Knowledgeable engaged employees are a companys best source of creative ideas for the nuts-and-bolts improvements that lead to excellence.
Final answer:

Indirect compensation is significant for retaining employees as it creates job security, motivates productivity, and reduces costs of recruitment and training. It also plays a role in managing modern workforce, which requires a more flexible and multi-faceted approach to retain.

Explanation:

Indirect compensation is important for recruiting and retaining employees in several ways. One of them is that it often works under an implicit contract, where the employer tries to maintain wages even when the economy or the business is not doing well, providing a form of protection for the employees. This implicit contract can make workers feel secure and motivated, hence improving productivity and reducing the likelihood of them leaving the firm.

Moreover, retaining employees from more modern generations can be more challenging since their expectations differ from those of previous generations; they tend to lack inherent company loyalty, hence, frequent rewards, praises, and feedback are essential. On the other hand, the efficiency wage theory argues that better pay results in higher productivity since the employees are motivated to work harder to maintain their current job because they realize that they could suffer a wage cut if they were to lose it.

Lastly, to avoid the costly and time-consuming endeavor of hiring and training new employees, employers often find it advantageous to pay a little more to the existing ones, a strategy that not only minimizes costs but also retains skilled and motivated employees.

Answers

 

The formula for perimeter is:

P = 2 h +  2 w

where P is perimeter = 120 cm, h is height, w is width

we are also given that: h = (2/3) w, therefore:

P = 2 (2/3) w + 2 w = 120

(4/3) w + 2 w = 120

w = 36 cm

 

Therefore l is:

l = (2/3) w = 24 cm

 

Hence the dimension should be 24cm by 36 cm

describe a situation in which 2 angles are both congruent and complementary

Answers

The only situation in which two angles are both congruent and complementary is when their measures are both 45°:

Two angles are complementary if their sum is 90°, and they are congruent if their measures are the same, say n. Therefore, to find two congruent angles which are complementary, we solve the following equation:

n+n=2n

2n = 90

2n/2 = 90/2

n=45


Two angles that are both congruent and complementary can be found in right angles.

Two angles that are both congruent and complementary can be found in the case of right angles. When two angles are right angles, they are both congruent (having the same measure) and complementary (adding up to 90 degrees).

Answers: 

x = 4
EF = 14
CF = 7
EC = 7

-------------------------------------------------------------
-------------------------------------------------------------

Work Shown:

C is the midpoint of segment EF. This means that EC = CF. In other words, the two pieces are congruent. 

Use substitution and solve for x
EC = CF
5x-13 = 3x-5
5x-13+13 = 3x-5+13
5x = 3x+8
5x-3x = 3x+8-3x
2x = 8
2x/2 = 8/2
x = 4

Now that we know that x = 4, we can use this to find EC and CF

Let's compute EC
EC = 5x - 13
EC = 5*x - 13
EC = 5*4 - 13 ... replace x with 4
EC = 20 - 13
EC = 7

Let's compute CF
CF = 3x - 5
CF = 3*x - 5
CF = 3*4 - 5 ... replace x with 4
CF = 12 - 5
CF = 7

As expected, EC = CF (both are 7 units long).

By the segment addition postulate, we can say EC+CF = EF

EC+CF = EF
EF = EC+CF

Answers

Final answer:

It took approximately 47 minutes for the patient's temperature to reach a record high of 105.8 degrees, calculated by subtracting the start time from the end time.

Explanation:

The subject question involves the calculation of time that elapses between two events - a start time of 9:54 a.m. and an end time of 10:41 a.m. To calculate this, we subtract the start time from the end time.

Begin by converting the times to a 24-hour clock, where 9:54 a.m. is 9.9 (as each minute represents a fraction of a full hour) and 10:41 a.m. is 10.68. Then, subtract 9.9 from 10.68 to get 0.78. This means that 0.78 hours has passed, which is equivalent to approximately 47 minutes when converted back into minutes (0.78 x 60).

So, it took approximately 47 minutes for the patient's temperature to reach the record high of 105.8 degrees.

Find three consecutive odd integers such that the sum of the first, two time the second and three times the third is 46

Answers

5+(2*7)+(3*9) = 46


I'm  assuming this is what you meant.

To find the three consecutive odd integers that satisfy the given conditions, we set up an equation x + 2(x + 2) + 3(x + 4) = 46, solved it to find x = 5, and then found the integers as 5, 7, and 9.

We are given a problem to find three consecutive odd integers where the sum of the first, two times the second, and three times the third equals 46. Let's label our integers as x (the first), x+2 (the second), and x+4 (the third), as the differences between odd integers are 2.

The equation, based on the problem statement, is:
x + 2(x + 2) + 3(x + 4) = 46

Distribute and combine like terms:
x + 2x + 4 + 3x + 12 = 46
6x + 16 = 46

Subtract 16 from both sides:
6x = 30
Divide both sides by 6:
x = 5

Therefore, the three consecutive odd integers are:
x = 5 (first integer),
x + 2 = 7 (second integer),
x + 4 = 9 (third integer).

Checking the solution: 5 + 2(7) + 3(9) = 5 + 14 + 27 = 46, which confirms our answer is correct.
