Step-by-step explanation:
The domain of a graph is all of the possible x values, and the range is all possible y values.
7. The graph goes on for both the x and y values, so the domain is (-inf, inf) and the range is (-inf, inf).
8. In this case, the domain is also (-inf, inf), but the range is [-2, inf) as there are no y values less than -2.
9. The domain is [-2, 2], as the x values only range from -2 to 2. The range is [-3, 3] as the y values range from -3 to 3.
10. The domain is (-inf, inf) because all x values are possible. The range is [-1, 1], as there are no y values greater than 1 or less than -1.

The scale from the actual coin to the photo is 8 mm to 2 cm. In the photo, the distance across the coin is 3.25 cm. What is the distance across the actual coin?
Answer:
13 mm
Step-by-step explanation:
Given that scale from actual coin to the photo is
8 mm to 2 cm.
Distance across the coin in photo is 3.25 cm.
To find:
Distance across the actual coin = ?
Solution:
First of all, let us learn about scaling concept.
The concept of scaling is used to represent the actual object as as image so that it can be drawn on a paper.
This scaling can result in a smaller image or a bigger image depending upon the size of object.
Here, 8 mm coin is represented as 2 cm coin on the photo.
Let us use unitary method to identify the distance across actual coin to the distance across photo.
2 cm ---- 8 mm
1 cm ------ [tex]\frac{8}{2} = 4\ mm[/tex]
3.25 cm ------- 4 \times 3.25 mm = 13 mm

A leather jacket was originally $129.99.
It is marked down to $79.99.
What percent discount is there?
amount saved = 129.99 - 79.99 = 50 dollars
Divide this over the original amount (129.99) to get
50/129.99 = 0.3846449726902 approximately
This rounds to 0.3846 and converts to 38.46% after you move the decimal point over to the right 2 spots.
The discount is roughly 38.46%Answer: 61.5% Or 62%
Step-by-step explanation:
79.99/129.99= .61535502730979
Move the decimal two times to the left to get 61.5%
If you round it to the nearest decimal you get 62%
if we know the area of a parallelogram is 25 square inches and its base length is 5 inches, what is the height
Answer:
5 inches
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the height )
Here A = 25, b = 5 , then
25 = 5h ( divide both sides by 5 )
5 = h
That is the height is 5 inches

Hey there!
The value of x in this figure is 60.
Angles in a four-sided shape add to 360 degrees.
We have an angle of measure 50, an angle of measure 130, and an angle of measure 120.
50+130+120=300.
Thus, the missing angle would be 60 degrees.
Let me know if this helps :)
Answer:
x = 60
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360 degrees
x+50 + 120+130 = 360
Combine like terms
300 +x = 360
x = 360-300
x = 60

Jenae works at a clothing store and gets a bonus of $10 a month, plus $0.50 every time she sells the item of the month.Every time a customer compliments her service to the manager, she gets a $2 bonus.If Jenae sold the item of the month 17 times and received 2 customer compliments, what will her bonus be this month? *
Answer:
$22.50
Step-by-step explanation:
Let's write what we know.
$10 a month bonus
+ $0.50 / per item of the month
$2 per compliment
We can write an equation:
T = Total bonus for the month
i = number of item of the month sales
c = number of compliments
T = $10 + $0.50i + $2c
i = 17
c = 2
Plug in the values:
T = $10 + $0.50i + $2c
T = $10 + $0.50( 17 )+ $2( 2 )
T = $10 + $8.50 + 4
T = $22.50
Her bonus for this month is $22.50
Jenae bonus for this month is $22.50.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that Jenae works at a clothing store and gets a bonus of $10 a month, plus $0.50 every time she sells the item of the month.
$10 a month bonus + $0.50 / per item of the month
$2 per compliment
We can write an equation;
T = Total bonus for the month
i = number of item of the month sales
c = number of compliments
T = $10 + $0.50i + $2c
i = 17
c = 2
Plug in the values;
T = $10 + $0.50i + $2c
T = $10 + $0.50( 17 )+ $2( 2 )
T = $10 + $8.50 + 4
T = $22.50
Hence, Jenae bonus for this month is $22.50.

Answer: 3. 4 2/3 ÷ √4/8 4. 4 2/3 - √4/8
Step-by-step explanation:
irrational number will never be changed into rational number when they do any operation with rational numbers.
4 2/3 is a rational number, which means the second term in the expression must be rational in order to make the expression entirely rational
√3 is not rational, thus, all the expressions that contains √3 is irrational.
The remaining have √4, but √4 is rational because simplifying it will become 2, and so expressions with √4 is rational
Answer:
Third and fourth.
Step-by-step explanation:
The first one is not because the second number is not rational; [tex]\sqrt{3}[/tex] is not rational.
The second one is not either for the above reason.
The third is because [tex]\sqrt{4}[/tex] is 2, which is rational.
Also the fourth for the previous reason.

Which factor could influence an employer to reduce the number of workers at his business?
A. An economic downturn
B. Better education in workers
C. The opening of a new location
D. High demand for the company's goods
Answer:
A
Step-by-step explanation:
if we had a economic turn down, basically people would lose money, so that means the consumers, so the producers will have a bunch of left over products because the people can't afford to buy as much, which means the company loses money, which means the employees must be let go of so the business doesn't go out of business
A] Economic Downturn could influence Employer to reduce number of workers at business.
Economic Downturn is a slowdown in economic activities for a considerable period of time. It is characterised by low demand by consumers & low production levels in businesses.
This situation implies that a rational employer would reduce the workers employed, as there is lesser demand & need of production.
Better educated workers, new location' opening, high demand of goods : are rather likely to increase employment levels instead of decreasing.

Samuel worked at a beach over the summer. He worked 6 hours a day, 4 days a week. He earned $7.50 per hour. How much money did he make in one week? He worked for 8 weeks over the summer. How much did he make in all this summer?
Answer:
Total earning in the summer = $1440
Step-by-step explanation:
Earning per hour for Samuel = $7.50
No. of hours worked in a day = 6
Earning for a day = Earning per hour for Samuel *No. of hours worked in a day
Earning for a day = $7.50 *6 = $45
___________________________________________________
No of days worked in a week by Samuel = 4
Earning for week = Earning for a day *No of days worked in a week by Samuel
Earning for week = $45*4 = $180

No. of weeks worked in summer = 8
Total earning in the summer = Earning for week *No. of weeks worked in summer
Total earning in the summer = $180*8 = $1440 (Answer)
Part 1: Explain, using complete sentences, the Transitive Property of Equality in geometric terms.
Part 2: Provide an example of the Transitive Property of Equality using segments or angles.
Answer:
Part 1: The transitive property of equality states that where given that item one is equal to item two, where item two is then equal to item three, then item one is also equal three.
Mathematically, the transitive property can be written as follows;
When X = Y, and Y = Z, then also X = Z
Part 2: The transitive property of equality can be represented using angles as follows
Given ∠A and ∠B are the base angles of an isosceles triangle, then ∠A ≅∠B also ∠B and ∠C are vertically opposite angles, then ∠B ≅ ∠C, therefore, ∠A ≅ ∠C.

Acquarium workers are making a mixture of salt water. The desired ratio is 90 grams of salt per liter of water. What is the ratio in ounces per gallon?
Answer: 12.07 ounce/gallon.
Step-by-step explanation:
given data:
desired ratio = 90grams / liter of water.
ratio In ounce/ gallon
first we convert our grams to ounce
= 98grams / 28.35
= 3.175 ounce.
converting liter to gallons
= 1/3.8
=0.263 gallons
therefore;
= 3.175 ounce / 0.263 gallons
= 12.07 ounce/gallon.

31) AD = 4
32) m∠EFG 28°
33) m∠CAF = 32°
34) DF = 3
Step-by-step explanation:
29) EF is given as being congruent to EG, therefore, EF = EG = 3
30) AE = EB = 8 Given
AG = AE + EG Segment addition postulate
AG = AE + EG = EB + EG = 8 + 3 = 11 Transitive property
31) m∠EAD = m∠EBG = 19° Given
m∠DFG + m∠EGF + m∠EAD = 180° Sum of angles of a triangle
∴m∠DFG = 180° - (m∠EGF + m∠EAD) = 180° - (28° + 19°) = 133°
A F = 7 Given
DF = EG = 3 Given
AD = A F - DF = 7 - 3 = 4 From segment addition postulate
32) m∠EFG = m∠EGF = 28° Given
33) m∠CAE = 51° Given
m∠CAE = m∠CAF + m∠EAD Angle addition postulate
∴ 51° = m∠CAF + 19°
