The lateral surface area of a cube is 400cm². Its total surface area is
_______
a)600cm² b) 2400cm² c) 500cm² d) 650cm²
Answer:
Step-by-step explanation:
Lateral surface area of cube = 4a²
4a² = 400
a² = 400÷4
a² = 100
a = √100 = √10*10
a = 10 cm
Total surface area = 6a²
= 6 * 10²
= 6* 100
= 600 cm²

3x + 4y = 17 Solve for y Explain how to solve the problem please
Answer:
y = 17/4 - 3/4x
Step-by-step explanation:
[tex]3x + 4y = 17[/tex]
Subtract 3x from both sides.
[tex]4y = 17 - 3x[/tex]
Divide by 4 from both sides to isolate y.
[tex]y = \frac{17 - 3x}{4} [/tex]

What is the theoretical probability of rolling a six on a fair six sided die?
Answer:
Probability = Number of desired outcomes ÷ Number of possible outcomes So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. Independent probabilities are calculated using: Probability of both = Probability of outcome one × Probability of outcome two

What is the slope of the line in the graph?
Answer:
The slope of the line in the graph is 1.
Step-by-step explanation:
Slope is determined by rise over run. Meaning that the number of units the slope goes up/down divided by the number of units the slope goes to the left/right is the slope. The rise is one, and the run is one. 1 over 1 equals 1.
Answer:
The slope of the line is 1.
Step-by-step explanation:
If you can either use rise over run to dtermine the slope or use the point slope formula. For example, take the two points (0,1) and (1,2) using the point slope formula, you'll get 1 in the end.

What is the domain:
What is the range:
Answer:
Domain: [-4,4]
Range: [-4,6]
Step-by-step explanation:
To domain pertains to the x-coordinates, while the range pertains to the y-coordinates.
Looking at the graph, we can see that the farthest point to the left is (-4,3) and the farthest point to the right is (4,6). Now, we know that the domain is [-4,4].
Looking at the graph, we can see the highest point is (4,6) and the lowest point is (0,-4). Now, we know the range is [-4,6].
Now, we know that the domain is [-4,4] and the range is [-4,6].
