A triangle has a base of 4 units and a height of 3 units. Mark draws the triangle again but
doubles the height. How does the area of the triangle change?
The area increases by 3 square units.
The area increases by 6 square units.
The area increases by 12 square units.
The area does not change.
Answer:
The area increases by 6 square units.
Step-by-step explanation:
The original area of triangle
A = 1/2 bh
a = 1/2 (4)*3
6 square units
Now we double the height
A = 1/2 (4) *6
A = 12 square units
The difference is 12-6 = 6 square units
Answer:
Second option: The area increases by 6 square units.
Step-by-step explanation:
A1 = ½ × 4 × 3 = 6 units²
A2 = ½ × 4 × 2(3) = 12 units²
Increase: 12 - 6 = 6 units²
Find the scale factor of a cube with volume 216 ft^3 to a cube with volume 1000 ft^3.
Answer:
Scale factor of cube to the smaller cube is 5 : 3.
Step-by-step explanation:
Ratio of the volumes of two cubes = [tex]\frac{\text{volume of large prism}}{\text{Volume of small prism}}[/tex]
= [tex]\frac{1000}{216}[/tex]
= [tex]\frac{125}{27}[/tex]
Scale factor of these cubes = [tex]\sqrt[3]{\text{ratio of the volumes of the cubes}}[/tex]
= [tex]\sqrt[3]{\frac{\text{volume of large prism}}{\text{Volume of small prism}}}[/tex]
= [tex]\sqrt[3]{\frac{125}{27} }[/tex]
= [tex]\frac{5}{3}[/tex]
= 5 : 3
Therefore, scale factor of cube to the smaller cube is 5 : 3.

Answer: A - one solution, B - Infinite solutions, C - no solutions
Step-by-step explanation:
Solutions of linear equations are any points at which both lines intersect. The point of intersection provides a point that lies on both lines and satisfies both equations - hence why it is called a "solution" to the system of equations.
In the first diagram, the lines intersect once. There is only one solution to this system of equations at (2, 4).
In the second diagram, the lines are identical. They intersect for any possible value, meaning it has infinite solutions.
In the third diagram, the lines are parallel. They will stretch to infinity without ever intersecting each other, so this system has no solution.

What are the domain and range of the function? f(x)=3/5x^5
Domain: (−∞, 0)∪ (0, ∞) Range: (0, ∞)
Domain: (−∞, 0)∪ (0, ∞) Range: (−∞, 0)
Domain: (−∞, ∞) Range: (−∞, 0)
Domain: (−∞, 0)∪ (0, ∞) Range: (−∞, 0)∪ (0, ∞)
Answer:
Domain: (−∞, 0) ∪ (0, ∞); Range: (−∞, 0) ∪ (0, ∞)
Step-by-step explanation:
See attachment.
We want to find the domain and range of the function [tex]f(x)=\frac{3}{5} x^5[/tex].
The domain is the set of all possible x-values that are included in the function, while the range is the set of all possible y-values that are included in the function.
Look at the graph.
We can see that the x-values can go into infinity except when approaching the line x = 0. Here, the function will never touch x = 0 because that would make the graph undefined. So, we can say that the domain is all real numbers except for x = 0, or (−∞, 0) ∪ (0, ∞).
It's the same thing with the y-values. Although it looks like the line is touching the y-axis, or the line y = 0, the graph actually is not - it's just going really close to it. So, the range is again (−∞, 0) ∪ (0, ∞).
Thus, the answer is D.
Answer:
Last one
Domain: (−∞, 0)∪ (0, ∞) Range: (−∞, 0)∪ (0, ∞)
Step-by-step explanation:
f(x) = 3/(5x⁵)
Since x is in the denominator, x can not be 0
Domain: all real values of x except 0
For y = 0, x has to be infinite therefore y can not be 0
Range: all real values except 0

Two number cubes are rolled sequentially. What is the probability that the first number cube shows a Four and the second number cube shows an odd number?
Answer:
[tex]\frac{1}{12}[/tex]
Step-by-step explanation:
This is an independent event probability problem , that is the first event does not affect the occurrence of the second event.The sample space of the first die is S1= {1,2,3,4,5,6}
The sample space of the second die is S2= {1,2,3,4,5,6}
1. the probability that the first number cube shows a Four pr (4)= [tex]\frac{1}{6}[/tex]
2. the probability that the second number cube shows an odd number=
odd numbers in the sample space are 1,3,5= 3
pr(odd) [tex]= \frac{3}{6} = \frac{1}{2}[/tex]
For the two event to happen the probability is = [tex]\frac{1}{6}*\frac{1}{2}=\frac{1}{12}[/tex]

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which statement about this experiment is true?
Question:
Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which statement about this experiment is true?
A) The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.
B) The ratio 92/200 represents the number of trials in this experiment.
C) The ratio 92/100 represents the theoretical probability of the coin landing heads up in this experiment.
D) The ratio 92/100 represents the number of occurrences of the coin landing heads up in this experiment.
Answer:
A) The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.
Step-by-step explanation:
Given that the number of times, n, Tia flipped a coin is 200 times, heads and tails landed 92 and 108 times respectively.
ie, n = 200
E(Head) = 92
E(Tail) = 108
Let's calculate the following probabilities:
Probability the coin landed heads =
P(H) = [tex] \frac{num of heads}{total num} = \frac{92}{200} = 0.46 [/tex]
Probability the coin landed tails =
P(H) = [tex] \frac{num of tailss}{total num} = \frac{108}{200} = 0.54 [/tex]
Here, the experimental probability of an event can be derived using:
Number of favourable events / total number.
The expermental probability of the coin landing heads up would be:
Number of heads / total number
[tex] = \frac{92}{200} [/tex]
Therefore the correct option is option A.
The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

A is the answer

Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary. Charlene is going to reduce her net income by $125 each month and put this money towards paying down her debt. What will Charlene’s new net income be?
Answer:
A. $113.70
Step-by-step explanation:
The new net income of Charlene is $113.7 if Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary.
What is debt?It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.
Charlene net income = 7% of her monthly salary
Charlene net income = 3410(7/100) = $238.7
After paying the $125 from the net income:
= 238.7 - 125
= $113.7
Thus, the new net income of Charlene is $113.7 if Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary.
