Answer 2

Answer:

- 8

Step-by-step explanation:

Determine the value of x

Answers

Answer: 8


22 is to 11 because they are both on the hypotenuse. Since 11 is half of 22, x would be half of 16, 8.

Answer:

I would think it is 8

Step-by-step explanation:

By assuming the triangles are equal to each other in a way that the larger triangle is the smaller triangle's length times 2. For example, one side of the smaller triangle is 11 so times 2 would be the larger triangle's side. So, by dividing 16 by two, you would get 8. Hope this helped and that I did it correctly!

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself

Answers

Answer:

3,250

Step-by-step explanation:

Let's go from left to right, using multiple of 12 times a power of 10 in the process.

What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.

12,000 * 3 = 36000

39000 - 36000 = 3000

What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.

1,200 * 2 = 2,400

3,000 - 2,400 = 600

What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.

120 * 5 = 600

600 - 600 = 0.

The answer to 39,000 over 12 is 3,250.

6. 188 students went on a field trip. Five buses were filled and 18
students traveled in cars. How many students were in each bus?

Answers

Answer:

34

Step-by-step explanation:

188 - 18 = 170 divided by 5 equals 34

Answer:

34 students per bus

Step-by-step explanation:

188 - 18 = 170, The number 170 is the total amount of students who were on buses

170 ÷ 5 = 34 This is the total number of students divide by the number of buses which gave the number of how many students were in each bus

Which of the following graphs represents a function? If you don’t know then please don’t write “i don’t know” or “I can’t help with that” Just for points.

Answers

Answer:

B. x

Step-by-step explanation:

The answer would be graph x. A function must be that one x value should only have one y value. graph w doesn't work since when you plug in 0, you get two y's. same thing with z. Y doesn't work since at x value of 3, it curves back so x value 2 has 2 y's. X is the only one that each x value has only one y.

Answer:

X

Step-by-step explanation:

For a relationship to be a function, every input has exactly one output, so for every x value there is only one value.

If you look at answer's w and z for x=1 there is two y values, therefore they are not functions, letter Y is tricky. Even though every x value has only one y value, If you were to extend the graph x=0 would have more than one y values.

That leaves X.  If you extend the graph of X every x value will only have one y value so it is a function

Answer:

Every day for four years, I would drive to my job, and every day at the same time, on the same route, I would notice the city bus. It would pull up next to me, and I would see all the people on board. Some would be reading. Some would be sleeping. Some would stare back at me. Every day, at the same time, it would follow me right to work. As I pulled into my parking space at work, I would see it around the corner, about a block away from my job. Then, one day, my car broke down. I had no way to get to work, and then, I remembered the bus. I decided to take it since I knew it was on the same schedule as I was. Since then, I have never driven to work again. Taking the bus is a useful method with which to travel because you can save a lot of money by using public transportation. One reason public transportation is useful is because it saves money. My commute to work was long, and it required a lot of gas. When I drove to work, I was spending $30 a week on gas. There are 52 weeks in a year. That translates to $1,560.00 a year I was spending on gas to get to work. When I started taking the bus, it cost $2 ($1 to get to work and another $1 to get home). Another way to save money is to use the toll road. That translates to $10 a week. That means that it cost me $520 a year to get to work. That's less than a third of what it cost to drive. It saved me $1,040.00. The funny part is that the reason my car broke down in the first place was because I was driving it constantly. 6 What is the central idea of this passage?

If you were going to solve -3(x + 5) = 27, what is the first step that you would do? Why did you start there?

Answers

Answer:

Step-by-step explanation:

Multiply -3 for x and for 5

-3x-15=27

When you have this type of equation the first thing you do is take off the parentesis

Then you pass the 15 to the other side and you get -3x= 27 +15 . After that you divide that for -3 and you get the x . In this case x= -14

calculate the distance between the two points shown on the graph below give your answer correct to 2 decimal places if necessary

Answers

Answer:

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=

=16+9−−−−−√=25−−√=5

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:

(x1+x22,y1+y22)
