The surface area of a cube is 96 square feet. Find the volume of the cube.
Answers
96ft² : 6 = 6 ft² - one wall surface
pattern on the surface of the cube
A = a²
a - the edge of the cube
A = a² ⇔ a=√A
a = √(16ft)² = 4ft
V = volume
V = a³
V = (4ft)³ = 64 ft³

YOUR ASSIGNMENT: Factory Lighting ProblemIn this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher. You are deciding whether to light a new factory using bulb A, bulb B, or bulb C. Which bulb would be better to use on the factory floor? Which bulb would be better to use in the break room? To answer these questions, you will compare the energy usage of the three bulbs. The amount of energy the lights use is measured in units of kilowatt-hours. A kilowatt-hour is the amount of energy needed to provide 1000 watts of power for 1 hour. 1. Circle the two bulbs you picked. incandescent Halogen Fluorescent 2. 3. Practice: Summarizing (3 points) Fill in the blanks. The energy usage of a light bulb is a function. The input for the function is _________, measured in hours. The output of the function is energy usage, measured in ____________. Identify the functional relationship between the variables. _________________ is a function of _________________. The graph of the function will show energy usage on the _____________ axis and time on the _______________ axis. 4. Practice: Organizing Information (2 points) Use the data given to complete the table for your first bulb. DATA TABLE A Time (hours) x Energy (kWh) y Point (time, energy) (x, y) 3 10 5. Practice: Organizing Information (2 points) Use the data given to complete the table for your second bulb. DATA TABLE B Time (hours)x Energy (kWh)y Point (time, energy)(x, y) 3 10 6. Practice: Organizing Information (5 points: 1 point for labels, 2 points for each graph) Label the axes of the graph with "Time (hours)" and "Energy (kWh)." Plot the points from Table A on the graph. Connect the points with a line. On the same graph, plot the points from Table B and connect them with a line. 7. Practice: Summarizing (1 point) Classify each of your graphs as increasing, decreasing, or constant. First bulb: ___________________ Second bulb:___________________ 8. Practice: Summarizing (2 points) Fill in the blanks. First bulb: When 3 is the input, the output is _____. When 10 is the input, the output is _______. Second bulb: When 3 is the input, the output is _____. When 10 is the input, the output is _______. 9. Practice: Summarizing (1 point) The workers leave the lights on in the break room for stretches of about 3 hours. Which light bulb would light this room using the least amount of energy? 10. Practice: Summarizing (1 point) The lights in the main room of the factory stay on for stretches of 9 hours. Which kind of light bulb would light this room with the least amount of energy?

In order to factor it must be equal to 0, so we have 2y^2+y-10=0. We factor this and get y=5 (we also get y=-4 but it is an extraneous root). now we can plug that into either equation and find that x=2.
this means our two numbers are 5 and 2

3(n+5)≥17 is the expression for three times the sum of a number n and 5 is at least 17.
What is an Inequality?
The relationship between two expressions or values that are not equal to each other is called inequality.
Given that three times, the sum of a number n and 5 is at least 17.
According to the question, the expression will be = 3(n+5)≥17
Hence, 3(n+5)≥17 is the expression for three times the sum of a number n and 5 is at least 17.

The solution to the equation 7/28 = 25/x is x = 100.
What is the solution to the equation?
Given the equation in the question:
7/28 = 25/x
To solve for the variable x in the equation 7/28 = 25/x, first, we cross multiply.
7/28 = 25/x
Cross-multiplying, i.e multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa:
Hence:
7 × x = 28 × 25
7x = 700
Now, isolate x by dividing both sides by 7:
7x/7 = 700/7
x = 700/7
x = 100
Therefore, x has a value of 100.
Option B) 100 is the correct answer.

2x+3y=6
2(0)+3(-2)=6
-6=6
So graph isn't the required graph.
Taking point (0,2) of graph 2;
2x+3y=6
2(0)+3(2)=6
6=6
So, graph 2 is the required graph.
Answer:
Option (c) is correct.
Step-by-step explanation:
Given : Equation of line 2x + 3y = 6
We have to graph the given equation
Consider the given equation of line 2x + 3y = 6
We first find the points for different values of x and y
And then plot these points.
1) Put x = 0
We get ,
3y = 6
y = 2
2) Put y = 0
We get,
2x = 6
x = 3
Thus, we get the points (0, 2) and (3,0)
Now plot these to obtain a line, we get, see attchment
Option (c) is correct.
