Answer: 9= -1.5 or -3/2
10= -11/6 or 1.8333
11= -10.9
12= 3.535
13= Town A is -3.33 Town B is -3 2/5, 2/5= .44, so town B is colder, as it is -3.44

9.
Explanation: So for question 9, you need to find the LCD (Least common denominator) so you list out the multiples of 8 and 4, when doing so, you find out that 8 is the LCD of both, since 8 is both a multiple of itself and of 4.
So, to get the answer, you do 4 * 2 and anything you do to the denominator (bottom number), you do to the nominator (top number).
So now you have -8/3/8 +6/2/8 then you just add the nominators and whole numbers like normal. You get, -2/1/8 (Remember you are adding a positive number to a negative number.)
Answer: -2/1/8
10.
Explanation: Same process as question 9.
Answer: -4/1/12
11.
Explanation: Read -7.3 out loud, it would be negative seven and 3 tenths, that makes it easy to convert as a fraction. It would be -7/3/10. Do the same for the other number, and you have -3/6/10, then you just add. You get -10/9/10.
Answer: -10/9/10
12.
Explanation: Same process as question 11. (You're in the thousandths now.) You get 3/535/1000. Reduce.
Answer: 3/107/200
13.
Explanation: You have 2 options here, to convert the decimal into a fraction, or to convert the fraction into a decimal, I'll be changing the fraction into a decimal, you wanna write it as a 10 as a denominator, so to get to 10 you multiply the denominator by 2, and anything you do to the denominator, you do to the nominator. So, -3/2/5 as a decimal is: -3.4, then you go ahead and compare them and you can see that the temperature in town A is colder.
Answer: The temperature in town A is colder.
14.
Explanation: For this one, you just subtract or add the amount to 7number. The dates don't matter, just telling you to do it in that order.
60.68 + 75.50 = 136.18
136.18 - 25.16 = 111.02
111.02 - 82.05 = 28.97
28.97 + 59.95 = 88.92
Answer: $88.92

1. What is the probability of an odd outcome?
2. What is the probability of an outcome less than 6?
Answers
Answer:
1. 50%
2.[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.
2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.
P = N / NP
Dice has 6 faces. I.E. 1,2,3,4,5,6
= 6
NP, therefore, is the total number of possible outcome.
Faces less than 6. (1,2,4, and 5)
N = 5
P = N / NP = [tex]\frac{5}{6}[/tex] ; it can't be reduced.

Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).
Answers
Answer:
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus
y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

the diagram shows a circle inside a square ABCDB AB = 20 cm. the radius of the circle is 9 cm. work out the area of the shaded region
Answers
Step-by-step explanation:
Area of the square = a²
= 20²
= 400cm²
Area of the circle = πr²
= 22/7 × 9²
= 22/7 × 81
= 254.57cm²
Area of the shaded region = Area of the square - Area of the circle
= 400cm² - 254.57cm²
= 145.43cm²
Adult tickets to a musical cost $15 and children's tickets cost $8. A total of 725 tickets were sold which brought in a total of $8775.
How many of each type of ticket were sold?
State the equation used to solve, along with both answers.
Answers
Given:
Cost of adult's ticket = $15
Cost of children's ticket = $8
Total tickets = 725
Total sales = $8775
To find:
The number of each type of ticket were sold.
Solution:
Let x be the number of adult tickets and y be the number of children's ticket.
Total tickets : [tex]x+y=725[/tex] ...(i)
Total sales : [tex]15x+18y=8775[/tex] ...(ii)
Multiply equation (i) by 15.
[tex]15x+15y=10875[/tex] ...(iii)
Subtract (iii) from (ii),
[tex]15x+18y-15x-15y=8775-10875[/tex]
[tex]3x=-2100[/tex]
[tex]x=-700[/tex]
Putting x=-700 in (i), we get
[tex]-700+y=725[/tex]
[tex]y=725+700[/tex]
[tex]y=1425[/tex]
Therefore, the number of adult tickets is -700 and number of child tickets is 1425.
Note: The number of tickets cannot be negative. So, there must be some error in the question.

Step-by-step explanation:
They're asking for a pattern.
17 + 5 = 22
22 + 5 = 27
27 + 5 = 32
So it starts at 17 and increases by five each time.
The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.

Explain how you calculate the constant of variation.
Answers
Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
