30. This is continuous because you can have a portion of a year.
31. This is continuous because time can be broken down into smaller intervals
32. This is discrete because you cant have a part of a team. x values between the given ones would give you a fraction of a team.
33. In this graph, the line is not continuous. Therefore, because there is no point at 2.5, 2.5 is not in the domain.
34. Even though the graph ends at x=6, all possible values of x between 0-6 are accounted for, making the line continuous. So, the line is continuous.
35.
a. To find the domain, we have to solve for b first by making m=0. So, 0=55-8.5b
-55 = -8.5b, which is 55/8.5, or 110/17
So, the domain is 0<=x<=(110/117)
This is a discrete line because you can only have whole numbers for "b" because you can only buy whole books
b.(cant really graph it on here :P )
c. When x = 0, y = 55, and when x = 110/117, y = 0. So the range is 0<=y<=55
36.
a. Because there is no limit to the function, the domain is x>=0. The function is continuous because the time can be broken down into smaller intervals
b. (cant really graph it on here :P )
c. The range is y>=0 because the least x can be is 0, but it can keep increasing.
37.
a. This does represent a linear function because the distance increases by .434 miles at every interval (every 2 seconds)
b. The domain would be t>=0 because you can't have negative time, but you can wait infinitely long. This should be continuous because time and distance can be broken down into smaller intervals.
c. (cant really graph it on here :P )
d. The smallest t can be is 0, and when t=0, d=0. Because domain is infinite, range is also infinite. Therefore the range is d>=0
38.
a. It is linear because there is an 'x' input and 'y' output and there are no exponents in either variable.
b. x can equal 0, and it can be infinite. So, the domain is x>=0. It is discrete because you cant have a partial service, only a whole.
c. (cant really graph it on here :P )
d. When x=0, y=30. Because domain is infinite, range is also infinite. Therefore the range is y>=30
43.
a. If you subtract 61.20 from 71.40, you can see that every hour, the earnings increase by 10.20 dollars. Therefore, the missing value is 61.20-10.20, or 51.00
b. Every hour you get 10.20.
44.
a. This is not a linear function. This is because the function breaks at t=5, which should be 300 if it was following the original pattern, which was d=60t
When t=1, d=60
When t=3, d=180.
But, when t=5, in the function, it equals 300 while in actuality, it equals 300
b. He is correct because if Car A is still following the function, it would have only gone 300 miles, while Car B had gone 310 miles.
Hope this helped!! Let me know if any of this is unclear or if you're still having some trouble!! :D

The value of the mixed number is A = 27/10
What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
Let the mixed number be represented as A
Now , the equation will be
A = 2 7/10 be equation (1)
On converting the mixed number to an improper fraction , we get
Multiply the whole number by the denominator and add the numerator to it to get the new numerator of the improper fraction
So , A = [ ( 2 x 10 ) + 7 ] / 10
On simplifying the equation , we get
A = 27/10
Hence , the mixed number to improper fraction is A = 27/10

a) The cost price of the jacket after the decreased amount is $ 35
b) The cost price of 2 jackets is $ 70
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the price of the jacket after decrease be = A
Now , the equation will be
The original price of the jacket = $ 39.50
The amount decrease in the price of the jacket = $ 4.50
So , the cost price of the jacket after the decrease in price is = original price of the jacket - amount decrease in the price of the jacket
Substituting the values in the equation , we get
The cost price of the jacket = 39.50 - 4.50
The cost price of the jacket = $ 35.00
So , the cost price of the jacket is $ 35.00
Now , the cost price of 2 jackets is = 2 x sale price of the jacket
Substituting the values in the equation , we get
The cost price of 2 jackets is = 2 x 35
The cost price of 2 jackets is = $ 70
Therefore , The cost price of 2 jackets is $ 70
Hence ,
a) The cost price of the jacket after the decreased amount is $ 35
b) The cost price of 2 jackets is $ 70

Final answer:
The given equation (9x100) + (8x10) = 7(1/1000) as a decimal is 980 = 0.007.
Explanation:
To convert the given expression into a decimal, we first need to evaluate the arithmetic expression on the left-hand side: (9x100) + (8x10). This can be done by simplifying the multiplication operations first, then performing the addition. Multiplying 9 by 100 gives us 900, and multiplying 8 by 10 gives us 80. Adding these two results together, we get 980. So the left-hand side of the equation becomes 980.
Next, let's convert the right-hand side of the equation, 7(1/1000), into a decimal. To do this, we need to divide 1 by 1000. Dividing 1 by 1000 gives us the decimal 0.001. Finally, we multiply this decimal by 7, giving us 0.007.
Therefore, the given equation (9x100) + (8x10) = 7(1/1000) as a decimal is 980 = 0.007.

Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
Length of a fence on a scale drawing = 6 cm
Scale = 1 cm : 4 m
Let the actual length of the fence be x
Since there is direct variation between the scale and actual.
According to ratio, we will have,
Hence, Option 'C' is correct.
