The total cost C, in dollars to tile a square floor is represented by the equation C = 16L², where L is the length of one side of the floor, in feet. Which of the following represents the cost, in dollars per square foot, to tile the floor?

Sanjay works as a teacher’s assistant for $20 per hour and tutors privately for $25 per hour. Last week, he made at least $100 working x hours as a teacher’s assistant and y hours as a private tutor. Which of the following inequalities models this situation?

A system of equations is a collection or set of equations that are dealt with together. These equations can be graphed and algebraically solved. The intersection of two lines is the solution to the system of equations. This article goes into detail about the Algebraic Technique To Solve System Of Equations.
¶A linear equation is one that has one or more variables and produces a straight line when plotted. The system of linear equations is defined as two or more linear equations with two or more variables that are all considered at the same time.

The volume of the right triangular prism shown is 96 cubic centimeters (cm³). What is the area, in cm², of one of the triangular bases of the prism?

Object A has a mass of x kilograms (kg). Object b has a mass of 1.1x kg. What is the ratio of the mass of object A to the mass of object B?

The table shows several values of x and their corresponding values of y, where k is a nonzero constant. If the relationship between a and y is linear, which of the following defines this relationship?

The table shows the results of a poll of 1,000 people. Respondents were asked to agree or disagree with the statement “I rely too much on my phone.” If a respondent who was selected at random disagrees with the statement, which of the following is closest to the probability that the respondent selected is at least 45 years old?

x² + 2x – 3 = 0
If x satisfies the given equation, which of the following could be a value of x + 3?

In the xy-plane, a circle with radius 2 has center (0, 0). Which of the following is a equation of the circle?

The scatterplot shows 10 values from a data set. Which of the following equations is the most appropriate linear model for the data shown?

The volume of a neodymium magnet is 2.50 cubic centimeters, and its mass is 18.5 grams. What is the density, in grams per cubic centimeter, of the magnet?

For a sample of 13 red alder trees, an arborist measured each tree’s diameter, in centimeters (cm), at a height of 1.4 meters. The arborist then counted the number of growth rings at this height. Each point in the scatterplot represents the diameter and number of rings for each tree. A line of best fit for these data is also shown.
A red alder tree will be selected at random from the sample. What is the probability that the selected tree will have a measured diameter that is greater that is greater than 30 cm?
