Find the rate of change from 2012 to 2016
A. -10.5 students per year
B. 10.5 students per year
C. -11.25 students per year
D. 11.25 students per year
Answers
Answer:
D. 11.25 students per year
Step-by-step explanation:
rate of change
[tex] = \frac{400 - 355}{2016 - 2012} [/tex]
[tex] = \frac{45}{4} [/tex]
=11.25
The rate of change from 2012 to 2016 is 11.25 students per year.
Therefore, the correct answer is D.
Given that a graph is showing the number of students in a class.
We need to find the rate of change from 2012 to 2016.
Also, from the graph we can see the number of students in 2012 and 2016 was 355 and 400 respectively.
To find the rate of change from 2012 to 2016, we can use the formula:
Rate of change = (Final value - Initial value) / Time interval
In this case, the initial value is the number of students in 2012, which is 355, and the final value is the number of students in 2016, which is 400.
The time interval is 4 years (from 2012 to 2016).
Plugging these values into the formula, we get:
Rate of change = (400 - 355) / 4
= 45 / 4
= 11.25
Therefore, 11.25 students have changed between 2012 and 2016 with this rate of change.

Help quick! i will give you 20 points. You have 412 pints of ice cream for your birthday party. If you are going to serve 34 pint to each guest, how many guests will you be able to serve?
Answers
Division word problems often ask you to split something evenly. You should solve this problem by dividing the total amount of ice cream by the amount you will serve each guest. After converting to fractions, 4.5 divided by .75. You will have enough to serve six guests, and no ice cream left over.

Answers
Answer:
Question 1: add 3a + 4a becuase they have the same variables. you should get 7a. Then subtract 10b and 4b because they have the same variables,You should get 6b. The answer is 7a+6b because you can't do anything with those numbers because of their variables and how they are not the same.
Question 2: The answer is x=10. to get the answer move all terms not containing x to the right side of the equation and add as normal.
Question 3: The answer is -5. Steps: move the equation around so there is a 2 on both sides of the equation, should look like this: 2x= -12 +2. Then add -12 +2 = -10. Then divide each term by 2 and simplify, should look like this: 2x/2 = -10/2. Then cancel the comments factor which is 2 should look like this: x = -10/2. After divide x by 1. Then divide -10 by 2 which equals -5.
Question 4: The answer is m=6. First multiply 6x2=12 then multiply that by 2 which should get u 24 then divide 24 by 4 =6
Question 5: sry I dont understand :(
Answer:
1. 7a+6b because 3a+4a=7a and 10b-4b=6b
2. x=10 because you add 3 to the other side to cancel it out and 7+3=10
3. x=6 because
2*m=2m and 2*6=12
24-12=12 and 12/2=6

A cake recipe requires flour and sugar in a ratio of 4 to 3. Which table has been generated using this ratio?
Answers
Answer:
The third table
Step-by-step explanation:
A ratio is a relationship that illustrates how many times one number contains another. For example, the ratio of 4:3 means there is 4 cups of flour for every 3 cups of sugar. The third table is the only one that increases proportionate to the ratio. This can be seen because when 4 is multiplied by 3 to get 12, so is 3 to get 9. This pattern continues, with both amounts being multiplied by the same number.

If you walk 3 kilometers in 30 minutes, what is your average speed in kilometers per hour?
Answers
Answer:
If you walk 3 kilometers in 30 minutes your average speed is 6 kilometers per hour.
Therefore, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.
What is the speed?
The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Here given that,
Here, you walk [tex]3[/tex] kilometers in [tex]30[/tex] minutes. So the average speed is :-
Speed = Distance/ Time
Distance is [tex]3km[/tex] and the time is [tex]30[/tex] minutes so,
[tex]S=\frac{3}{30}\\\\\\S=0.1[/tex]
Hence, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.

Answer:
The common facor is x-3.
Step-by-step explanation:
The first expression can be factored with a difference of squares, x+3 and x-3. You can check that by multiplying them together to get x²-9. Knowing that you need a common factor, one that works for both expressions, you can immediately eliminate A and B. The second expression, x²-5x+6, has to share one of these two factors. To factor this, you find the numbers that multiply to the c term and add to the b term. (Ax²+bx+c) so b is -5 and c is 6. All you have to do is find out which two numbers add to -5 and multiply to 6. You start with factors of 6, which are +-6 and +-1, and +-3 and +-2. Say you try 6 and 1 first. The b term is negative, so these two added have to add to a negative number, which means positive 6 and positive 1 won´t work. The only way to add to -5 is to add 1 to -6 or -6 to 1, but multiplying those together gives you -6, and you need positive 6 in the c term. That leaves you with -2 and -3. they add to -5, and multiply to -6, which means that your common term is x-3. Test this by expanding your result, (x-2)(x-3), if you get the original expression theyre both factors.
