What is 5.75% of $6,000? (Express answer as dollars as cents.)
Answer:
The answers are:
345 dollars
34500 cents
Step-by-step explanation:
In order to determine the answers, we have to know about the percentage notation. For any "x" value that is expressed as x%, it is the same that:
x%=[tex]\frac{x}{100}[/tex]
So, first we determine the value in dollars and then we determine the value in cents, where:
1 dollar=100 cents
In dollars $:
=5.75%*$6000
=[tex]\frac{5.75}{100}[/tex]*$6000
=$345.00
In cents c:
=5.75%*6000*100
=[tex]\frac{5.75}{100}[/tex]*6000*100
=34500.00 cents

The graph of a linear equation contains the points (4,1) and (-2,-11). Which point also lies on the graph?
A. (1,1)
B.(1,-5)
C.(1,-2)
D.(1,-7)
Answer:
Option B is correct.
(1 , -5) lies on the graph.
Step-by-step explanation:
Given the points (4,1) and (-2 , -11)
First find the linear equation for the given points.
Equation of line for two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]
is given by: [tex]y-y_1 = (\frac{y_2-y_1}{x_2 - x_1}) (x-x_1)[/tex]
Substitute the given points (4,1) and (-2 , -11) in above equation to find the equation of line:
[tex]y-1=(\frac{-11-1}{-2-4})(x-4)[/tex]
or
[tex]y-1=(\frac{-12}{-6})(x-4)[/tex]
or
[tex]y-1=2(x-4)[/tex]
Using distributive property on RHS ( i.e, [tex]a\cdot (b+c) = a\cdot b+ a\cdot c[/tex] )
we have;
y -1 = 2x-8
Add 1 to both sides of an equation;
y-1+1 = 2x-8+1
Simplify:
y = 2x -7
Therefore, the equation of line for the given point is: y =2x - 7 ....[1]
To find which points lies on the graph ( i.e, Line)
Substituting the given options in equation [1] we have;
A . (1,1)
Put x =1 and y =1
[tex]1 = 2\cdot 1 -7 = 2-7[/tex]
1 = -5 which is not true.
Similarly
B. for (1, -5)
[tex]-5= 2\cdot 1 -7 = 2-7[/tex]
-5 = -5 which is true.
C. for (1, 2)
[tex]2= 2\cdot 1 -7 = 2-7[/tex]
2 = -5 which is not true.
And
D. For (1 , -7)
[tex]-7= 2\cdot 1 -7 = 2-7[/tex]
-7 = -5 which is also not true.
Therefore, the only point which lies on the line graph [1] is; (1 ,-5)

What information can be used to compare linear relationships?
Sample Response:
Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.

A fantasy board game makes use of four dice. The first is a standard 6-faced die, the second die has 4 faces, and the other two have 10 faces each. If all the dice are thrown together and their combination dictates a certain outcome of the game, how many possible outcomes exist?
Answer:
2400
Step-by-step explanation:
Given : The first is a standard 6-faced die, the second die has 4 faces, and the other two have 10 faces each.
To Find: If all the dice are thrown together and their combination dictates a certain outcome of the game, how many possible outcomes exist?
Solution:
No. of faces of first die = 6
No. of faces of second die = 4
No. of faces of third die = 10
No. of faces of fourth die = 10
Now we are supposed to find the the number of possible outcomes exist.
So, Number of possible outcomes if all the dice are thrown together :
= [tex]6 \times 4 \times 10 \times 10[/tex]
=[tex]2400[/tex]
Hence there are 2400 possible outcomes if all the dice are thrown together and their combination dictates a certain outcome of the game.

What does exclamation point mean in math?
In mathematics, an exclamation point represents a factorial, meaning the product of an integer and all the positive integers below it. For example, 5 factorial, or 5!, is 5 x 4 x 3 x 2 x 1 = 120. Unlike exponentials, factorials involve consecutive multiplication of integers.
Explanation:In mathematics, the exclamation point is used to represent a factorial. Factorial indicates the product of an integer and all the positive integers below it. For instance, 5! would be 5 x 4 x 3 x 2 x 1 = 120. This calculation method is a significant concept especially in exponential arithmetic.
Contrary to exponential notation, factorials do not deal with the concept of powers or repeated multiplication of the same number. Instead, they focus on consecutive multiplication of descending positive integers. For example, 3! is evaluated as 3 x 2 x 1 = 6, instead of 3 x 3.

To use the linear combination method and addition to eliminate the y-terms, by which number should the second equation be multiplied?
A. -4
B. -1/4
C. 1/4
D. 4
To use the linear combination method and addition to eliminate the y-terms, the second equation should be multiplied by 4.
What is equation?An equation is like a relationship between two or more variables. It is expressed in equal to form. Equation of two variables looks like: ax+ by=c.
It is solved to find the value of variables.
How to solve equation?The given equations are 7x+16y= -2 and 9x-4y=22 and we have to solve using linear combination method.
First we have to change -4y to -16y because after we have to do addition so we will multiply the second equation by 4 which makes the equation as under:
36x-16y=88
Adding equation 1 and 2
7x+16y+36x-16y=-2+22
42x=20
x=20/42
x=10/21
Put the value of x in 7x+16y=-2
7(10/21)+16y=-2
10/3+16y=-2
16y=-2-10/3
16y=-16/3
y=-1/3
Hence to solve the equations we need to first multiply second equation by 4 which is option D.

What is the measure of (arc) BC?
A. 55
B. 110
C. 48
D. 96
Answer:
(D)[tex]96^{\circ}=(arc)BC[/tex]
Step-by-step explanation:
It is given from the figure that m∠BAC=48° and arcAC=110°.
The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc.
Now, using the above property, we have
[tex]m{\angle}BAC={\frac{1}{2}}(arc)BC[/tex]
Substituting the given values, we get
[tex]48^{\circ}=\frac{1}{2}(arc)BC[/tex]
[tex]96^{\circ}=(arc)BC[/tex]
Thus, the measure of the arc BC is 96 degrees.
Hence, option D is correct.

Suppose that some country had an adult population of about 50 million, a labor-force participation rate of 60 percent, and an unemployment rate of 5 percent. how many people were unemployed?
Based on the labor force participation rate, the number of unemployed people is 1.5 million people.
The unemployed rate is based on the labor force participation rate and not the adult population.
The labor force is 60% and in absolute value this is:
= 60% x 50 million people
= 30 million people
The unemployment rate is 5% of this:
= 5% x 30 million
= 1.5 million people
In conclusion, there are 1.5 million unemployed people
