Answers
Answer:
1. 28
2. -65
Step-by-step explanation:
The rule I learned, was that if there is an even number of negative signs, the outcome is positive. If there is an odd number of negative signs, the outcome is negative.
In the first question, we have 2 negative signs. So the outcome is positive. 28 is positive.
In the second, we have 3 negative signs, so the outcome is negative. -65 is negative.

Justify how this compound was created from a recycling of carbon in the carbon cycle. Use complete sentences to explain your answer.
Answers
The process that arrow C signifies is the burning of fossil fuels in order to present carbon dioxide into the atmosphere. The mentioned procedure in the carbon cycle is comparatively new as humans were not able to generate huge concentrations of carbon dioxide by burning fossil fuels until the emergence of the Industrial revolution.
Part 2:
The phenomenon, which could discharge the compound into the air is the burning of fuels. It is an oxidation reaction in which the carbon present in the hydrocarbons in the fuel is oxidized to carbon dioxide by the presence of oxygen in the air. The carbon dioxide discharged into the atmosphere contributes to the greenhouse effect.
Part 3:
The elements, which produce it are conserved at the time of the carbon cycle by the Law of Conservation of Matter. According to this law, the matter is neither consumed nor produced, it only gets transformed. So, at the time of chemical procedures in the carbon cycle, the atoms of carbon are never destructed, however, they get rearrange and modify into distinct molecules. The mentioned cycle is essential for maintaining life on Earth.

What is the solution to the following system of equations: 2x + 3y = 5 AND 5x = 5y -25
Answers
Answer:
point form (-2,3)
Equation form
x=-2, y=3
Step-by-step explanation:
solve for the first variable in one of the equation, then substitute the result into the other equation.
Answer:
(-2,3)
Step-by-step explanation:
5x=5y-25
x=y-5 divide both sides by 5
use substitution.
2(y-5)+3y=5
2y-10+3y=5 distribute the parenthesis
5y-10=5 combine like terms
5y=15 add 10 to both sides
y=3 divide both sides by 5 to get y alone
5x=5(3)-25 replace y with 3, the value we found above
5x=15-25 multiply 5 and 3
5x=-10 subtract 25 from 15
x=-2 divide both sides by 5 to get x alone

Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate? (3 points)
Answers
Answer: From the table we see there is a relation between x and y values
Every step change of x = 0.5, every step change of y = 2
This relation is linear. The formula for linear function is:
y = mx + b
Using to pairs of points to get the slope and y-intercept
(0, 60) and (1, 64)
Calculating the slope:
m = (64 - 60)/(1 - 0) = 4/1 = 4
y - intercept is 60 as per point (0, 60)
So the function is
y = 4x + 60
Part A
Yes. Described above
Part B
y = 4x + 60
Part C
Slope is the steepness of the line.
y -intercept is the lowest score with no time spent studying

Write an equivalent expression for -6(-7+2z)
Explain in full steps
Answers
Answer:
42 - 12z
Step-by-step explanation:
We can find an equivalent expression by using distributive property
Distributive property: whenever there is a number outside of the parenthesis you multiply that number by whatever is in the parenthesis
So for -6(-7+2z) we would multiply the number outside of the parenthesis (-6) by what's inside of the parenthesis ( -7 and 2z )
-6 * -7 = 42
-6 * 2z = -12z
An equivalent expression would be 42 - 12z
-6(-7+2z)
42-12z

How many three digit numbers have digits whose sum is greater than 2?
Answers
Answer:
896
Step-by-step explanation:
Let's talk first about how many 3 digit numbers there are. The first 3 digit number is 100 and the last is 999. So there are 999-100+1 numbers that are 3 digits long. That simplifies to 900.
Now let's find how many of those have a sum for the digits being 1, then 2 ? Then take that sum away from the 900 to see how many 3 digit numbers have the sum of their digits being more than 2.
3 digit numbers with sum of 1:
The first and only number is 100 since 1+0+0=1.
We can't include 010 or 001 because these aren't really three digits long.
3 digit numbers with sum of 2:
The first number is 101 since 1+0+1=2.
The second number is 110 since 1+1+0=2.
The third number is 200 since 2+0+0=2.
That's the last of those. We could only use 0,1, and 2 here.... Anything with a 3 in it would give us something larger than or equal to 3.
So there are 900-1-3 numbers who are 3 digits long and whose sum of digits is greater than 2.
This answer simplifies to 896.

Below are the data collected from two random samples of 500 American students on the number of hours they spend in school per day (rounded to the nearest hour):
Number of hours in school per day 4 5 6 7 8 Sample A: Number of students 70 100 125 135 70 Sample B: Number of students 80 90 120 125 85 Meg concludes that students spend a mean of 7 hours in school each day. Tara thinks the mean is 6 hours. Who is correct—Meg or Tara? Explain your answer in two or three sentences. Make sure to use facts to support your answer.
Answers
Answer:
The mean would be 6, meaning Tara is correct.
Step-by-step explanation:
The reason to why this is the answer is that I had to add all the “number of hours in a school per day” to get 30. Then, you would have to divide 30 by 5 (because you have five different hours for a school day) to get 6. Your mean would be 6 because mean is adding up the amount of something, then dividing it of how many numbers you added.
Tara think correct mean i.e., 6 . The student spends a mean of 6 hours in school each day.
Tara is correct.
What is mean of the data?Arithmetic mean or mean or average is the number that is obtained by adding the values of all the items of a series and dividing it by the number of observations.
As per given that :
Time slots (in hours): 4, 5, 6, 7, 8
Sample A: 70 100 125 135 70
Sample B: 80 90 120 125 85
For Sample A, the mean will be
[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3035}{500}[/tex]
=6.07
For Sample B, the mean will be
[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3045}{500}[/tex]
=6.09
The average mean will be = [tex]\frac{6.07+6.09}{2}[/tex]

First u need to anylase both equations to do that u need to look at 922 and 9.22 not the 3.75 and 37.5 because the decimal point doesn't justify anything. So you see 922 is bigger than 9.22.

NEED HELP ASAP NO FALSE ANSWERES. Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in
cleaning supplies per car wash. Write an equation to represent this situation
Answers
Answer:
y = 70x + 35
Step-by-step explanation:
$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)
the +35 is the tips extra/ constant that will be added after the jobs are done.
x is the amount of car washes done
y would be the profit received.
thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)
Answer:
Step-by-step explanation:
Profit = Income less outgo
= (car wash income + tips) - (supplies)
$250 = ($75n + $35) - ($5n), or
$215 = $70n (where n represents the number of cars washed)
This comes out to n = $215/$70, or approximately 3 car washes.

1. 75 grams of Toasty Oats for 9 grams of protein
2. Toasty Oats
Step-by-step explanation:
By using cross multiplication we can figure out how many grams of Toasty Oats is needed for 9 grams of protein:
[tex]\frac{12}{100}* \frac{9}{x}[/tex] (x) being the grams of toasty oats.
Cross multiply: 12x = 900
solve for x: 900/12 = x
x = 75 grams of toasty oats needed for 9 grams of protein
To find which one has the better ratio of proteins to grams of cereal,
we can multiply the amount of cereal together to get the same denominator
12/100 and 5/45
12/100 * 9
5/45 * 20
to get the same denominator
108/900 and 100/900
we can see the (12/100)*9 has more protein to grams of cereal ratio than (5/45)*20.

if Hannah made twice as many cookie as Sam that means the amount of cookies Hannah made are equivalent to 36 x 2= c. if we were to multiply 36 x2 we'd get how many cookies Hannah made and if we needed to find out how many Sam made we'd have to divide Hannah's cookies by two. giving us 36 = c ÷ 2. making C the correct option.
