y = something x plus or minus a number
going through each line it isn't a linear pattern ( they don't all have the same difference when subtracted or added together)
so now you play around with quadratic equations ( square roots, powers, etc.)

Consider two identical iron nails: one nail is heated to 95 °c, the other is cooled to 15 °c. the two nails are placed in a coffee cup calorimeter and the system is allowed to come to thermal equilibrium. what is the final temperature of the two nails
Answers
In this case, the final temperature of the two nails will be an average of their initial temperatures, which is 55 °C.
Explanation:When two objects at different temperatures come into contact, heat is transferred from the object with higher temperature to the object with lower temperature until they reach thermal equilibrium.
In this case, the heated iron nail at 95 °C will transfer heat to the cooled iron nail at 15 °C when they are placed in the coffee cup calorimeter.
The final temperature of the two nails will be an average of their initial temperatures, which is (95 °C + 15 °C) / 2 = 55 °C.
the difference of a given month's rainfall from the average monthly rainfall is called the deviation. What is the deviation for each month shown?
average monthly rainfall 3.6
given month may 2 3/5; june 7/8; July 4 1/4
Answers
Answer:
Deviation:
may : 1
june: 0.875
july: 0.65
Step-by-step explanation:
It's given that the difference of a given month's rainfall from the average monthly rainfall is called the deviation .
To find : deviation for each month: may 2 3/5; june 7/8; July 4 1/4:
Solution :
Average monthly rainfall = 3.6
Rainfall in may = [tex]2\frac{3}{5}[/tex] = 2.6
Deviation = Average monthly rainfall - month's rainfall ( may ) = 3.6 - 2.6 = 1
Rainfall in june = 3.6 - 0.875 = [tex]\frac{7}{8}=2.725[/tex]
Deviation = Average monthly rainfall - month's rainfall ( june ) = 0.875
Rainfall in july = [tex]4\tfrac{1}{4}=\frac{17}{4}=4.25[/tex]
Deviation = Average monthly rainfall - month's rainfall ( july ) = 4.25 - 3.6 = 0.65

If josh spends 4,000 a year on tuition and fees, 1,200 a year on books, and forgoes earning 10,000 a year, how much will his four year degree cost
Answers
The total cost of the four-year degree for Josh, when considering tuition and fees, book costs, and his foregone earnings, would be 60,800 dollars.
Explanation:The cost of a four-year degree would be the sum of tuition and fees, book costs, and forgoing potential earnings per year, multiplied by the four years of the degree. Let's break it down:
Tuition and fees cost: 4000 dollars/yearBook costs: 1200 dollars/yearForgone earnings: 10000 dollars/yearTherefore, the annual cost would be the sum of these, which is 4000 + 1200 + 10000 = 15200 dollars/year. Then we multiply this by the 4 years, 15200 * 4 = 60800 dollars. So, the four-year degree would cost Josh 60800 dollars, considering the provided expenses and forgone earnings.

What is the domain and the range of the relation represented by the ordered pairs? {(6,6),(−1,3),(3,6),(0,4)}{(6,6),(−1,3),(3,6),(0,4)} Select each correct answer.
Answers
Let's review: The domain is all the possible x values of a relation/function. To get the domain, we look at the x values in the ordered pairs.
The domains are: {-1, 0, 3, 6} - as you can see these are the x values of each pair.
Let's review: The range is all the possible y values in a relation/function. To find the rang, we look at the y values of the pairs.
The ranges are: {3, 4, 6} - notice how there are two "6" in those pairs, and when writing the range, you don't need to repeat the number if it's already written.

2 3 4 and the top cards are 1 4 3 2.
The problem is asking to match the top cards to the bottom ones then adding 1
to get the doubles.
So 1 should be corresponding to two. Since 1 + 1 = 2
4 should be corresponding to 5. Since 4 + 1 = 5
3 should be corresponding to 4. Since 3 + 1 = 4
And lastly, 2 should be corresponding to 3. Since 2 + 1 = 3

Find factors of 15y^2-50y+35=
Answers
15y^2-50y+35 =
= 5(3y^2 - 10y + 7)
Now we need to factor the trinomial.
3 can be factored as 3 * 1
7 can be factored as 1 * 7 or (-1) * (-7)
Since the middle term is negative, we need to use -1 and -7 as the factors of 7
= 5(3y - 7)(y - 1)
and then focus on factoring 3y^2 - 10y + 7. Looking at the first and last coefficients 3 and 7, I'd form possible rational roots, which would include 7/3 and -7/3.
Using synthetic division, I'd determine whether either 7/3 or -7/3 is a root of 3y^2 - 10y + 7:
____________
(7/3) / 3 -10 7
7 -7
--------------------
3 -3 0
Since there is no remainder, I'd conclude that 7/3 is a root of 3y^2 - 10y + 7, and that (3x-7) is a factor. Look at the coefficients 3 -3; they tell us that (3x-3) is another factor.
Now let's take back that '5' we factored out earlier.
Factors of 15y^2 - 50y + 35 are 5, (3x-7) and (x-1).
Multiply these 3 factors together as a check. I found that (3x-7)(x-1) comes out to 3x^2 - 10x + 7, and that multiplying this by 5 produces
15y^2 - 50y + 35, which is the expression we started with.
What is the equation of the line in standard form? (-3, 1) (3, 2)
Answers
Final answer:
The equation of the line passing through the points (-3, 1) and (3, 2) in standard form is (1/6)x - y = 5/6.
Explanation:
The equation of a line in standard form is Ax + By = C, where A, B, and C are constants. To find the equation of the line passing through the points (-3, 1) and (3, 2), we need to find the values of A, B, and C.
To do this, we can use the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept. First, let's find the slope using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the values, we get:
m = (2 - 1) / (3 - (-3)) = 1/6
Now, we can substitute the slope (m) and one of the given points (x, y) into the slope-intercept form to find the y-intercept (b). Using (-3, 1) as the point:
1 = (1/6)(-3) + b
Simplifying, we get:
b = 5/6
Now, we can substitute the values of m and b into the standard form equation to get:
(1/6)x - y = 5/6

Answers
Answer:
Option c is correct
Distance in miles are; 30, 40, 45 miles
Step-by-step explanation:
As per the statement:
If the length between points on a map is 6 inches, 8 inches, and 9 inches.
It is also given that:
1 in. = 5 miles
We have to find the distance in miles:
For 6 inches.
1 in. = 5 miles
6 in. = [tex]6 \cdot 5 = 30[/tex] miles
Similarly, for 8 inches:
8 inches = [tex]8 \cdot 5 = 40[/tex] miles
For 9 inches:
9 inches = [tex]9 \cdot 5 = 45[/tex] miles
Therefore, distance in miles are; 30, 40, 45 miles
A jar holds 128 fluid ounces of juice. The label says the jar has 16 servings. How many fluid ounces are needed for 80 servings?
Answers
Divide 80 servings by 16 servings, and 5 should be the quotient. Therefore, there are 5 jars of juice. Multiply 128 by 5 since 128 fluid ounces are in one jar. The answer should be 640 fluid ounces.
Answer: 640 fluid ounces
Step-by-step explanation:
We assume that the fluid ounces in jar is directly proportional to the number of servings.
Given : A jar holds 128 fluid ounces of juice. The label says the jar has 16 servings.
Ratio of fluid ounces of juice to number of servings =[tex]\dfrac{128}{16}[/tex] (1)
Let x denotes the fluid ounces are needed for 80 servings.
Ratio of fluid ounces of juice to number of servings =[tex]\dfrac{x}{80}[/tex] (2)
From (1) and (2) , we have
[tex]\dfrac{x}{80}=\dfrac{128}{16}[/tex] [in direct variation ration remains constant.]
[tex]x=\dfrac{128\times80}{16}=640[/tex]
Hence, 640 fluid ounces are needed for 80 servings.
