Answer:
1. The independent variable is a and the dependent variable is m
2. The domain is discrete
Step-by-step explanation:
let us explain the difference between discrete or continuous domains
Discrete domain: It is a set of input values that consists of only certain numbers in an interval.
Continuous domain: It is a set of input values that consists of all numbers in an interval.
In the question
m = 3a, where
m is the amount of money m in dollars
Each customer can buy a maximum of three apps
1.
∵ m is depended on the value of 3a
∴ m is the dependent variable ⇒ (output)
∴ a is the independent variable ⇒ (input)
∴ The independent variable is a and the dependent variable is m
2.
∵ The domain the input values
∴ Each customer can buy a maximum of three apps
→ That means it is a certain numbers
∴ The domain is discrete

Complete the division problem by determining the number that should be placed in the box. Division bracket with 12 on the left, 5496 inside, and 458 above it. Underneath the 5496, there is a minus 4800. Then there is a solid line with 696 under the line. There is a minus sign, and an empty box followed by a solid line. Beneath the line, there is a 96 minus 96 underneath. There is a solid line and a 0 to end the problem. (4 points)
Answer:
600
Step-by-step explanation:
Just below the solid line, there is the remainder and just above the solid line, there is a multiple of 12.
The number with a negative sign is being subtracted to the above number.
The first subtraction is mentioned as
5496-4800=696, observe that 696 is just below the solid line.
Now, proceeding further in the same way, the number below the second solid line is 96 which is obtained when the number in the box is being subtracted to the above number 696.
Let the number in the box is [tex]x[/tex]. So,
[tex]696-x=96[/tex]
[tex]\Rightarrow x=696-96=600[/tex]
Hence, the required number in the box is 600.

(-1,-2) would result in a relation that is no longer a function.
In the table, there's already x = -1 and y = -4. Function only gives a single y-value with x-value. If a single x-value gives two y-values then it'd not be Function.
If we add (-1,-2) in the table. The domain will be repetitive. Basically, we already have (-1,-4) and if we add (-1,-2) in the table, a single x-value will give TWO y-values which is not a function.

The diagram shows two parallel lines cut by a transversal. One angle measure is shown.
Find the values of A B C D E F and G
Answer:
a= 126
b= 54
c= 126
d= 54
e= 126
f= 54
g= 126
Step-by-step explanation:
To find a you would subtract 54 from 180 which would give you 126
Since a and b are another linear pair they would also add up to 180.
Then you move to c which is a linear pair with 54 so it is 126.
Because a and g are alternate interior angles they are congruent and they you continue with the same process for the first and check by seeing if the angles would be obtuse or acute to see if the angle measures would be correct.
The measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
It is given that:
The diagram shows two parallel lines cut by a transversal.
As we know from the definition of the vertically opposite angles:
b = 54 degrees
a + c = 54 + b (a = c)
2a = 54x2
a = 54 degrees
Since a and g are opposite interior angles, they are congruent, so you proceed with the process as you did for the first and check to see if the angles are acute or obtuse to ensure that the angle measurements are accurate.
Similarly:
b = 54
c = 126
d = 54
e = 126
f = 54
g = 126
Thus, the measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.

A math classroom has 30 students. The teacher assigned the students a project and told them they could turn it in on Monday, Tuesday, or Wednesday. 12 of the students turned the project in on Monday. 13 of the students turned the project in on Tuesday. The rest of the students turned the project in on Wednesday. How many students turned their project in on Wednesday?
Answer:
5 students.
30 - 12 - 13 = 5.
Answer:
The answer is 5
Step-by-step explanation:
We need to find out how many students turned in the project on Wednesday. In order to do this, this is what we need to do.
1. First we need to subtract 12 from 30 since 12 is how many students turned in the project on Monday.
2. 30 - 12 = 18
So now we have 18.
3. Next we need to subtract 13 from 18 since we know that 13 is how many students turned in the project on Tuesday.
4. 18 - 13 = 5
At the end we end up with 5.
So 5 students turned in the project on Wednesday.

If 5 of mathjuce contain 120grams of sugar how many grames of suger are in a case of 24 cans of mathjuce
Answer: 576 grams of sugar
Explanation: To solve this, you must do this following. First, you'd need to divide the 5 cans of MathJuice by their grams of sugar content. By doing this, you will find out how many grams of sugar are in each can. So, you'd divide 120 by 5 and get 24. This means that there are 24 grams of sugar in each can. Now, you'd need to multiple that by the number of cans in a case of MathJuice. You need to multiply 24 by 24. Doing this will get you a product of 576. Therefore, there are 576 grams of sugar in a case of MathJuice.

How is the pontiac's Rebellion different from the French and Indian War?
Answer:
Pontiac's Rebellion, which came closely on the heels of the French and Indian War, made the British seek more peaceful relations with Native Americans in the Ohio Valley. They issued the Proclamation of 1763, which prohibited colonists from settling in the region, as a way to avoid further conflict.
Step-by-step explanation:
You plan to take a 7-day trip to California. You estimate that it will cost $275 per day to visit Los Angeles, and $400 per day to visit San Francisco. Your total budget for the 7 days is $2,300. How many days could you spend in each location, so that you spend your entire budget?
Answer:
You can spend 4 days in Los Angeles and 3 days in San Francisco.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=7 (1)
275x+400y=2,300 (2), where:
x is the number of days to visit Los Angeles
y is the number of days to visit San Francisco
First, you can solve for x in (1):
x=7-y (3)
Now, you can replace (3) in (2):
275(7-y)+400y=2,300
1,925-275y+400y=2,300
125y=2,300-1,925
125y=375
y=375/125
y=3
Finally, you can replace the value of y in (3) to find x:
x=7-3
y=4
According to this, the answer is that you can spend 4 days in Los Angeles and 3 days in San Francisco.
Please Solve x2 = 121
Answer:
x = 60.5
Step-by-step explanation:
ok this simple you already have the variable and the number on different sides
x2 = 121
divide each side by 2
x2 / 2 = x
121 / 2 = 60.5
x = 60.5
Answer:

Divide 121 by 2, or just add 600.5 or multiply it by 2 and you get 121
The ratio of men to women at a business office is 6:13. There are 95 people working at the company. 9. 10. How many more women are there then men?
the ratio is 6:13 meaning 6 is for men and 13 is for women so add 6 and 13 to get 19 . since the total number of people was 95 it will be represented by the total ratio 19 then to get the number of men it will be 6 times 95 then divide by 19 for women 13 times 95 then divide by 19 after that subtract men from women

How long would it take for a car to travel 200 km if it has an average speed of 55 km/hr?
Answer:
11,000 km/hr
Step-by-step explanation:
Distance= speed x time
time= 55 km/hr
speed= 200 kn
=200 km x 55 km/hr
= 11,000 km/hr
At an average speed of 55 km/hr the car will cover a distance of 200 km
in 3.6 hours.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
We know, distance = speed×time or d = st.
Given, A car to travel 200 km if it has an average speed of 55 km/hr.
Therefore, From d = st we have,
200 = 55t.
t = 200/55.
t = 3.6 hours.
What is the relative speed between two moving objects?The relative speed is the net speed of two different objects with respect to each other.
If two objects move in the same direction we take the difference between their speeds.
If two objects move in the opposite direction we take the sum of their speeds.
