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
14= I'm not sure about number 14, sorry about that
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

28.97 + 59.95 = 88.92

Bianca buys 4 band shirts and 3 pairs of pants for $159, and Gianna buys 3 of the same shirts and 2 of the same pairs of pants for $113.
How much does it cost to buy 5 band shirts and 5 pairs of pants?
Answer:
$150
Step-by-step explanation:
ok, so first you want to create your equations. let s=shirts, and p=pants. 4s+3p=159, and 3s+2p=113. next you want to get one variable in each equation to be the same. I multiplied the first by 2 and the second by 3 to make the ps the same. now we subtract our equations. (9s+6p=339) - (8s+6p=318) this gives you s=21. Now we put that in to solve for p, it doesnt matter which of the 4 equations. 4(8)+3p=159 = 3p=127 = p=42 1/3. now we just multiply them to find the cost of 5 of each. which is the answer above.

78 % of the class scored a C or above on their test. If there are 35 students in the class, how many scored a C or higher? Write and solve a proportion for this situation.
Answer:
27 students
Step-by-step explanation:
[tex]\frac{78}{100} =\frac{x}{35} \\[/tex]
cross multiply and you get 27
All this question is trying to ask is to find 78% percent of the total number of student in the class.
So first convert 78 to decimal by dividing it by 100: [tex]\frac{78}{100} = 0.78[/tex]
Next multiply that with the total number of students which is 35.
So, [tex]0.78 * 35 = 27.3[/tex]
Now I don't think there can be a decimal here. The question must be wrong or the percentage might be incorrect. But, just for sake, we'll round it up so the final answer would be: [tex]27[/tex]
The proportion would be: [tex]273:10[/tex]

Which of the following does NOT reflect the number line
Answer:
B
Step-by-step explanation:
The number line shows that x must be greater than or equal to 0 and less than but not equal to 3. This means that the only answer that does not reflect this is 0<x<3, because again, x must be greater than or equal to 0. Not just greater than.

(-6,+ 00)Carlos is packing bags for treats at a party. Every bag has exactly the same amount of treats in it. Carlos has 25 granola bars and 35 small popcorn balls. What is the greatest number of treat bags Carlos can make?
Answer:
5 bags
Step-by-step explanation:
Given
[tex]Granola\ Bars = 25[/tex]
[tex]Popcorn\ Balls = 35[/tex]
Required
Determine the greatest number of bags
This question illustrates greatest common factor (GCF).
The number of bags will be solved by getting the GCF of 25 and 35.
This is shown below:
[tex]25 = 1 * 5 * 5[/tex]
[tex]35 = 1 * 5 * 7[/tex]
[tex]GCF = 1 * 5[/tex]
[tex]GCF = 5[/tex]
Hence, Carlos will need 5 bags

A) 3r > 34,
3r 34
r/3 11.3
r 10.2
C) the squirrel ran at least 11.3 feet per second
the squirrel ran faster than 11.3 feet per second
the squirrel ran no faster than 102 feet per second
the squirrel ran slower than 102 feet per second
_______________________________________________________
Answer:
✔ 3r > 34
✔ r > 11.3
✔ The squirrel ran faster than 11.3 feet per second.
Step-by-step explanation:
1. The Squirrel's speed is 3r > 34
2. The solution of the inequality is r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
A squirrel runs across a road in 3 seconds.
The road was more than 34 feet wide.
1. The Squirrel's speed is
3r > 34
2. The solution of the inequality is
r > 34/3
r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.

Use the formula to find the midpoint between a segment with endpoints
(0,5) and (-4, 6). *
Answer:
Step-by-step explanation:
(x₁ ,y₁) = (0 , 5) & (x₂, y₂) = (-4 , 6)
[tex]Midpoint = (\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})\\\\[/tex]
[tex]= (\frac{0 - 4}{2} , \frac{5+6}{2}) \\\\= (\frac{-4}{2} , \frac{11}{2})\\\\=(-2 , 5.5)[/tex]
The mid-point is the average of the respective values for x and y.
So, the formula for the mid-point would be: [tex](\frac{x_{2} + x_{1}}{2}, \frac{y_{2} + y_{1}}{2})[/tex]
So for your problem this would be:[tex](\frac{-4}{2}, \frac{11}{2})[/tex]
So the final answer would be: [tex](-2, 5.5)[/tex]

which equation could represent each graphed polynomial function
PLEASE HELP FAST!!!
Answer:
y = x⁴- 5x² + 4
y = x(x + 3)(x - 2)
Step-by-step explanation:
1). y = x⁴- 5x² + 4
= x⁴- 4x² - x² + 4
= x²(x² - 4) - 1(x²- 4)
y = (x² - 1)(x² - 4)
y = (x - 1)(x + 1)(x - 2)(x + 2)
Therefore, zeros of this polynomial are,
x = -2, -1, 1, 2
From the given graphs, first graph has the zeros (x-intercepts) as x = -2, -1, 1, 2.
So the graph (1) represents the polynomial → y = x⁴- 5x² + 4
2). Second graph shows the x-intercepts at x = -3, 0, 2
Since, y = x(x + 3)(x - 2) is the polynomial with x intercepts at x = -3, 0, 2
Therefore, y = x(x + 3)(x - 2) represents the second graph.

Ryan and his children went into a bakery and will buy cupcakes and brownies. Each cupcake costs $4.75 and each brownie costs $1. Ryan has a total of $50 to spend on cupcakes and brownies. Write an inequality that would represent the possible values for the number of cupcakes purchased, cc, and the number of brownies purchased, b.b.
Answer: 4.75c+1b ≤50
Step-by-step explanation: One cupcake costs $4.75, so “c” cupcakes cost $4.75. One brownie cost $1, so “b” brownies cost 1b. The total 4.75c+1b must be less or equal to $50.
Gregory may choose between two accounts in which to invest $5000. Account A offers 2.3% annual interest compounded monthly. Account B offers continuous compound interest. Greg plans to leave his investment untouched (no further deposits and no withdrawals) for 10 years.
need help calculating account b's balance
Answer:
see below
Step-by-step explanation:
principal = $5,000
interest rate = 2.3%
account A: compound monthly for 10 years
account B: compound continuously for 10 years
account A: compound monthly for 10 years
A = P (1 + r/12)^ r*t
= $5,000 (1 + .023/12)^ 12(10)
= $6,291.6
account B: compound continuously for 10 years
FVn = PV * e^r*t
= $5,000 * e ⁽⁰ ⁰²³ˣ¹⁰⁾
= $6,293
Gregory may chose account B. (but the difference is only $1.40)
Gregory may choose account B.
Given that,
Principal = $5,000 .The interest rate = 2.3% .Account A: compound monthly for 10 years .Account B: compound continuously for 10 years
Based on the above information, the calculation is as follows:
For Account A[tex]A = P (1 + r\div 12)^ {r\times t} \\\\= $5,000 (1 + .023\div 12)^ {12(10)}[/tex]
= $6,291.6
For account B
[tex]FVn = PV \times e^{r\times t}\\\\ = $5,000 \times e^ {0.023\times 10}[/tex]
= $6,293
Therefore we can conclude that Gregory may choose account B.
