The dance committee hired a DJ for the fall dance. The DJ charges
$125 per hour in addition to $55 for an assistant. The committee
wants to keep the total cost under $600. Which inequality represents
the maximum amount of hours the DJ will play at the dance?
Answer: 4 hours
Step-by-step explanation:
4 Hours
Explanation:
Make h = hours
You add the $55 extra cost for the assistant
$125h + $55 = $555
Use additive inverse to isolate the term with the variable
$125h + $55 - $55 = $555 - $55
Use multiplicative inverse to isolate the variable
[tex]\frac{125h}{125}[/tex] = [tex]\frac{500}{125}[/tex]
Hours would be: 4 Hours.

Translate the following equation into words: 5c - 4 = 11 Five, times a number minus four, is eleven. A number, times five minus four, is eleven. Five times a number, subtracted from four, is eleven. Four less than the product of five and a number, is eleven.
Answer:
Four less than the product of five and a number, is eleven.
Step-by-step explanation:
"The product of five and a number": 5c
"Four less than": - 4
"is eleven": = 11
"Four less than the product of five and a number is eleven":
5c - 4 = 11
Four less than the product of five and a number is eleven
No is cProduct of 5 and c is 5c
4 less than it means 5c-4
The result is 11

The area of a rectangle is 49d + 91
The length is an integer higher than 1, but is a known number.
Find the width of the rectangle.
Assuming that L and d are known numbers, we can write.
[tex]W = \frac{49d + 91}{L}[/tex]
How to get the width of the rectangle?
Remember that for a rectangle of width W and length L, the area is given by:
A = L*W
In this case, the area is 49d + 91, and the length is a known number, so we know the value of L.
Then we can write:
A = L*W = 49d + 91
To get the value of W, we need to isolate it on one side of the equation.
We can do that by dividing both sides by L.
[tex]W = \frac{49d + 91}{L}[/tex]
We assume that d and L are known, so with the above rational expression, we have W totally determined.

Answer:
No, corresponding angles aren't congruentStep-by-step explanation:
We have a transversal and lines intersecting with it.
The angle measures formed by the lines and the transversal are not all equal to each other.
Four of the angles measure 85° and one 79°.
These are corresponding angles (the angles which occupy the same relative position at each intersection where a straight line, transversal, crosses two or more others).
If corresponding angles are equal, the lines are parallel.
In our case all the lines intersecting the transversal are parallel apart from the one with different angle measure.
Therefore, correct answer choice is:
No, corresponding angles aren't congruentIn the diagram,
B (5,9)
A (2,3)
the points A, B and C lie on the straight line y = 2x-1
The coordinates of A are (2, 3).
The coordinates of B are (5, 9).
Given that AC = 3AB, find the coordinates of C.
0
y=2x+1
C
Answer:
C = (11, 21)
Step-by-step explanation:
The relation AC = 3AB can be used to find the coordinates of C given those of A and B.
__
C -A = 3(B -A)
C = 3B -2A . . . . . add A to both sides
C = 3(5, 9) -2(2, 3) = (15 -4, 27 -6) . . . . use the given points for A and B
C = (11, 21)

Is the vertex of the graph a maximum or a minimum?
Answer:
maximum
Step-by-step explanation:
Concepts
The vertex of a graph represents the turning point in a parabola.
Example: The graph shown in your question first steadily increases, but then at the point (1,3), it begins to go down. The point (1,3) is called the vertex in this case because it symbolizes the turning point.
Application
We are asked to determine if the vertex of this graph is a maximum or minimum. If the vertex is maximum, it's the highest point on the graph. If it's the minimum, it's the lowest point on the graph. Using your stunning eyes, you can see that the vertex is the highest point on the graph, making the answer maximum.
51% of a university's freshman class are majoring in Economics. If 4590 students in the freshman class are Economics majors, how many students are in the freshman class?
Answer:
2340
Step-by-step explanation:
4590*.51=2340.9
Because you can not have .9 people, you round down to 2340
2341 students are in the freshman class.
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
Total no. of students in the freshman Economics majors = 4590
51% students of a university's freshman class,
Let x no. of students in the freshman class,
x = 51/100×(4590)
x = 0.51×(4590)
x = 2340.9
x = 2340.9 ≈ 2341
Hence, 2341 students are in the freshman class.
