Question

Amy joined a gym with a $61 enrollment fee. The equation below can be used to find the total Amy has paid, y, if she has belonged to the gym for x months = 45x + 61 What does the 45 represent in the equation?

Answer 1

The 45 represents the monthly fee that Amy pays for belonging to the gym.

Answer 2

What is the slope of the line that passes through the points (-2, 2) and (-1, 7)?

Answer 3

To find the slope of the line passing through two points, we can use the formula:

slope = (y2 - y1) / (x2 - x1)

Using the points (-2, 2) and (-1, 7), we have:
x1 = -2, y1 = 2
x2 = -1, y2 = 7

slope = (7 - 2) / (-1 -(-2))
slope = 5 / 1
slope = 5

Therefore, the slope of the line that passes through the points (-2, 2) and (-1, 7) is 5.

Answer 4

Which of the following is an irrational number?
A. 3.7
B. 121 Square Root
C. 65 Square Root
D. 8 over 9 (Fraction)

Answer 5

An irrational number is a number that cannot be expressed as a ratio of two integers.

Out of the options given:
A. 3.7 is a rational number because it can be written as the fraction 37/10.
B. 121 Square Root is 11, which is a rational number.
D. 8 over 9 is a fraction which is a rational number.

Therefore, the irrational number in the list is C. 65 Square Root.

Answer 6

Write 75,000 in scientific notation.

Answer 7

To write 75,000 in scientific notation, we move the decimal point to have a number between 1 and 10, and then express it as the product of that number and a power of 10.

75,000 can be written as 7.5 x 10^4 in scientific notation.

Answer 8

Convert 3 over 4 percent to a decimal

Answer 9

To convert a percent to a decimal, you divide the percentage by 100.

3% in decimal form can be computed as:

3 / 100 = 0.03

Therefore, 3% written as a decimal is 0.03.
