What is the % gain if 35 is increased to 49?

Correct!
Wrong!

To calculate the percent increase, you can use the following formula:

Percent Increase = ((New Value – Original Value) / Original Value) * 100

In this case, the original value is 35 and the new value is 49. Plugging these values into the formula:

Percent Increase = ((49 – 35) / 35) * 100
= (14 / 35) * 100
= 0.4 * 100
= 40%
Therefore, the percentage increase from 35 to 49 is 40%.

Find a common linear connection between each pair of integers. then locate the phrase that is absent.
(3, 1)
(0.3, 0.1)
(-6, -2)
(1/5, 1/15)
(36, 12)
(1/3, ___)

Correct!
Wrong!

To identify the missing term in the pair (1/3, ___), we need to look for a common linear relationship between the numbers in each pair.

If we observe the pattern in the given pairs, we can see that the second number is obtained by dividing the first number by 3. This indicates a linear relationship where each number is divided by 3 to obtain the next number.
Applying the same pattern to the given pair (1/3, ___), we can divide 1/3 by 3:
(1/3) / 3 = 1/3 * 1/3 = 1/9
Therefore, the missing term in the pair (1/3, ___) is 1/9.

Find the missing word in the geometric series given below:
-2, 1/2, – 1/8, 1/32, – 1/128, ____.

Correct!
Wrong!

The given sequence is a geometric sequence, where each term is obtained by multiplying the previous term by a common ratio.

To find the missing term, we need to determine the common ratio between consecutive terms. By observing the pattern, we can see that the common ratio is -1/4. Each term is obtained by multiplying the previous term by -1/4.

Using this common ratio, we can calculate the missing term as follows:
-1/128 * (-1/4) = 1/512
Therefore, the missing term in the sequence is 1/512.

There is a corporation with twenty employees. The lowest-paid employee makes $150 per week, while the highest-compensated employee makes $260. Which of the following figures may serve as a reliable approximation of the company’s total weekly payroll?

Correct!
Wrong!

To estimate the total weekly payroll for the company, we need to consider the range of salaries and the number of employees.

Given that the lowest-paid person earns $150 per week and the highest-paid person earns $260 per week, we can calculate the possible range of total weekly payroll by multiplying the lowest and highest salaries by the number of employees.

What is the % drop if 25 is reduced to 15?

Correct!
Wrong!

To calculate the percent decrease, you can use the following formula:

Percent Decrease = ((Original Value – New Value) / Original Value) * 100

In this case, the original value is 25 and the new value is 15. Plugging these values into the formula:

Percent Decrease = ((25 – 15) / 25) * 100
= (10 / 25) * 100
= 0.4 * 100
= 40%

Therefore, the percentage decrease from 25 to 15 is 40%.

An accomplishment exam was taken by 300 kids. Each student received a score that was higher than 57 but less than 90. Which of the following figures best represents the students’ average score?

Correct!
Wrong!

Look for 0.94’s comparable form.

Correct!
Wrong!

An equivalent form of 0.94 can be expressed as a fraction by placing the decimal value over a power of 10. In this case, 0.94 can be written as 94/100.

Simplifying the fraction further, we can divide both the numerator and denominator by their greatest common divisor, which is 2. Thus, 94/100 simplifies to 47/50.

Therefore, an equivalent form of 0.94 is 47/50.
