A manager recorded the performance review scores for each employee and placed the results in the bar chart below. All employees received a rating on each of the Evaluation Categories. If Person 6 obtained the highest score possible, what score did Person 2 receive? Use the graph and tables below.
Answers
The score of person 2 is 30.
What is a bar chart?A bar chart is a graph that shows the numerical values of variables represented by the height rectangles of equal width. In a bar graph, the rectangles must be of equal width and the space between each bars must be equal.
Total score of person 6 with the highest score possible : highest score x number of options
5 x 9 = 45
This means that on the bar chart, the value of person 6's rectangle is 45. This means that each the value of the graph increases by 5. This means that each line increases by the value of 5.
Score of person 2 = number of lines to the height of the bar x 5
6 x 5 = 30

The domain of the given relation is: {x| x = –7, –6, 2, 3, 11}.
What is a domain?A domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values to a function and the domain of a graph comprises all the input numerical values which are shown on the x-axis.
Additionally, the horizontal extent of a graph represents all domain values and they are read and written from smaller to larger numerical values, and from the left of a graph to the right.

Find the lengths of UV and ST and determine whether they are congruent.
Hint: Congruent line segments have the same length.
Answers
The length of both UV and ST is [tex]3\sqrt{2}[/tex] and hence they both are congruent.
Here, we are given two lines- UV and ST.
We can find the length of the lines using distance formula. According to distance formula, distance between two points- (x1, y1) and (x2, y2) is given as-
[tex]\sqrt{(x2-x1)^{2} + (y2 - y1)^{2} }[/tex]
Here, for UV,
the two endpoints are- (1,0) and (4,3)
thus, the length of UV will be-
[tex]\sqrt{(4-1)^{2} + (3 - 0)^{2} }[/tex]
= [tex]\sqrt{(3)^{2} + (3 )^{2} }[/tex]
= [tex]\sqrt{9 + 9 }[/tex]
= [tex]\sqrt{18}[/tex]
= [tex]3\sqrt{2}[/tex]
Similarly, the two endpoints of ST are- (-2,-1) and (1,-4)
thus, the length of UV will be-
[tex]\sqrt{(1+2)^{2} + (-4 +1)^{2} }[/tex]
= [tex]\sqrt{(3)^{2} + (-3)^{2} }[/tex]
= [tex]\sqrt{9 + 9 }[/tex]
= [tex]\sqrt{18}[/tex]
= [tex]3\sqrt{2}[/tex]
So we can see that UV = ST = [tex]3\sqrt{2}[/tex], which means that both of them are congruent. Hence, option 1 is the correct answer.

Answers
The absolute change in the town's population from 2008 to 2010 is 1,050 and the percentage change is 32.3%.
Here, we are given that the population of a town increased from 3,250 in 2008 to 4,300 in 2010.
The absolute change can be calculate as-
Final population count - initial population count
= 4,300 - 3,250
= 1,050
Thus, absolute increase = 1,050
Now, the percentage increase can be calculated as follows-
percentage change = absolute change in population/ initial population count × 100
= 1,050/ 3,250 × 100
= 10500/ 325
= 32.3%

On his road trip, Leon stops to refuel and get some snacks. He has the following purchases:

1 apple for $0.89
2 bottles of vitamin water for $1.39 each
Leon must pay 7.5% sales tax on everything but the gas, which already has tax included in the per gallon price. If
Leon paid $44.64, then he
for his purchase.
a. did not pay enough
b. paid the correct amount
C.
paid $2.60 too much
d.
paid $3.11 too much
Please select the best answer from the choices provided
Answers
y=12(2.89)+(2(1.59)+.89+2(1.39))+.075p
This is a function, meaning that y=output (total cost), which we are given is 44.64, so y=44.64. Also notice that there is a variable “p.” This variable “p” simply means the price disregarding gas. We substitute y in and solve the equation using PEMDAS.
44.64=34.68+(3.18+.89+2.78)+.075p
44.64=34.68+(6.85)+.075(6.85)
Now, you see that “p” was replaced with the price disregarding gas, so we need to find the sales tax (7.5%=.075) of the food products and add that to the whole equation.
44.64=34.68+6.85+.51375
44.64=34.68+7.36375
44.68≠42.043
Notice that after simplifying, the equation is an inequality; therefore, we must subtract 44.68-42.043=2.637, and rounding down to the nearest tenth of 2.60.
Your answer is that Leon overpaid by $2.60
The correct option is that;
C. Leon overpaid for his purchase by $2.60 if he paid $44.64.
What is the difference between a sales tax and a use tax?The vendor, who is acting as the state's agent, collects the sales tax and remits it to the state on behalf of the final customer. The use tax, on the other hand, is self-assessed and paid by the final customer.
Given that;
Purchase fuel = 12 Gallons per $2.89 per gallons (including Tax)
2 Granola Bar for $1.59 per bar
1 apple for $0.89
2 bottles of vitamin water for $1.39
The sales Tax rate is 7.5%
Required to calculate the difference amount of Actual Paid and Actual Purchase =?
Fuel = 12 x 2.89 = $34.68 (including tax)
Granola Bar = 2 x 1.59 = $3.18
Apple = 1 x 0.89 = $0.89
Vitamin Water = 2 x 1.39 = $2.78
Total Purchase excluding fuel without tax is,
= $3.18 + $0.89 + $2.78
= $6.85.
Adding sale tax on $6.85 at the rate of 7.5% = $7.36
Hence, Total Purchase including Tax is,
$7.36 + $34.68 = $42.04
Thus, there is a clear difference that Leon paid 2.60 more than his actual purchase. He paid $ 44.64 and his actual purchase is 42.04 the difference between that is $2.60.

Answers
The limit dimensions of the part are 3.135 inches and 3.155 inches
How to find the limit dimensions of the part?The given parameters are

Answers
Answer: 75 hours
Step-by-step explanation:
"Aisha can make 50 bars of soap in 75 hours"
The division is one of the four fundamental arithmetic operations. The time it will take to make 50 soap bars if they both work together is 25.4543 hours.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Brianna can make 50 bars of soap in 40 hours, and Aisha can make 50 bars of soap in 75 hours. Therefore, we can write,
Soaps Made Briana in an hour = 50 bars/40 hours
= 1.25 soap bars per hour
Soaps Made Aisha in an hour = 50 bars/75hours
= 0.7143 soap bars per hour
Now, together the number of soap bars they can make in an hour is,
Number of soap bars in an hour = 1.25 + 0.7143 soap bars per hour
= 1.9643 soap bars per hour
Further, the time it will take to make 50 soap bars if they both work together is,
Time is taken = Number of soaps/ Number of soaps in an hour
= 50 soap / 1.9643 soap bars per hour
= 25.4543 hours
Hence, the time it will take to make 50 soap bars if they both work together is 25.4543 hours.

It should be noted that the wind speed is 70km per hour and the plane speed is 490km per hour.
How to illustrate the information?Based on the information given, the following an be illustrated.
Let P = speed of plane
Let w = speed of wind
The appropriate equation will be:
(P + W) (3/2) = 840 ....... i
(P - W) × 2 = (840 / 2) ...... ii
P + W = 560 .....i
P - W = 420 ......ii
Subtract the equations
2P = 980
P = 980 / 2 = 490
P + W = 560
490 + W = 560
W = 560 - 490
W = 70
Therefore, the wind speed is 70km per hour and the plane speed is 490km per hour.
