By counting the numbers of options for each selection, we will see that:
A) There are 10,000 different codes.B) There are 90 different combinations.C) There are 720 different combinations.How to get the numbers of combinations?A) The code has five digits, and the first digit is fixed (we know that it must be 7) so we only care for the other 4.
The second digit has 10 possible options.The third digit has 10 possible options.The fourth digit has 10 possible options.The fifth digit has 10 possible options.The total number of combinations is given by the product between the numbers of combinations:
C = 1*10*10*10*10 = 10,000 codes
So the correct option is the first one.
B) Again, we need to count the number of options for each possible element.
There are 5 drinks, 6 main dishes, and 3 desserts.
So for a meal of 1 drink, 1 main dish, and 1 dessert, the total number of different combinations is:
C = 5*6*3 = 90
There are 90 different possible meals.
C) How Janice can arrange the 6 books?
We need to count how many options we have for each place on the shelf.
In the first place, there are 6 options (one for each book).In the second place, there are 5 options (because we already placed one).On the third place, there are 4 options.And so on for the other 3 places.Then the number of combinations is:
C = 6*5*4*3*2*1 = 720
There are 720 ways of ordering the books.

They graph it in a werid way so I’m hoping u could take a screenshot and then graph it.
Answer:
Look at solution
Step-by-step explanation:
Remember that the x-axis is the time so you start at 0. The y-axis is the amount of snow so it says it starts at 1 inch so you start at (0,1).
When using coordinates remember (x,y) the x is the horizontal axis and y is vertical.
The next few steps deal with slope. The slope is always rise/run. so when it says it snowed for an average of 1 inch per hour, you go one up and one to the right to create the line. When it stopped snowing, the snow (i assume) stays the same so you just have a horizontal line for 5 hours indicating the same amount of snow. Then the snow becomes 3 per hour so you have to go up 3 from where you left off and over 1. Do that for 7 hours.
I hope you read this explanation because this is the basics of graphing. Next time you can try it by yourself :)
Customers at a candy store took a survey. The results showed that 126 customers preferred chocolate candy. This represented 35% of the total number of customers who took the survey. How many customers took the survey?
Answer:
360
Step-by-step explanation:
1. Set up your equation!
[tex]\frac{35}{100}[/tex] = [tex]\frac{126}{x}[/tex]
2. Cross multiply to solve!
100 times 126 = 12600
35 times x = 36x
3. Continue!
12600=35x
4. Divide the coefficient on both sides to get the variable by itself
[tex]\frac{12600}{35}[/tex]=x (the 35 cancels out)
12600 divided by 35 = 360
And there’s your answer! 360
Which expression is equivalent to |x| > 9?
A. x > –9 and x < 9
B. x > –9 or x < 9
C. x < –9 and x > 9
D. x < –9 or x > 9
Answer:
C
Step-by-step explanation:
when you do the absolute value you take out the sign
x > 9
but with absolute value there is also a negative answer. and with the greater than sign it would switch to less than.
x < -9

we know that linear equations always have a curve that is a straight line (constant gradient) so if we draw each graph out, we can determine which is the linear graph, based on which has a straight line curve. i drew all 4 graphs out, and B was the only straight lined graph, hence this must be the answer. i have attached photos of my graphs above :)

Now is your chance to think about the United States Constitution as a living document. Your task is to propose a new amendment to the Constitution. Write the amendment you are proposing below. Then list three reasons why you believe this amendment should be added to the Constitution.
The 13th amendment because This amendment abolished slavery and involuntary servitude. For what’s happening now I think we need this amendment added to the constitution right now because a lot of people are dying for their race. Not only that but they also get accused of things that aren’t even they don’t know what happened. And it’s really sad because some people get plastic surgery because of their skin.

Which table represents the following equation? y=−9x+2 PLEASE HELP!!!!! I NEED TO BE DONE BEFORE 12
Table (C) represent the equation y = -9x + 2.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
y = -9x + 2.
To find the table that represents the given equation.
Substitute x = 0 in the equation, as in all the options the value of x is 0, so satisfy the value of y for the value of x = 0.
y = -9 (0) + 2
y = 0 + 2
y = 2
The value of y is 2, when x = 0.
The table in option (c) satisfies the condition.
Therefore, option (c) is correct option.
