Answer:
700,000
Step-by-step explanation:
To explain this, we need to know the basics.
If you look at the number 790,390, you should automatically know that you can also write the same number as:
700,000 + 90,000 + 300 + 90
How did we do this?
Because each number in 790,390 has a <u>value.</u>
In fact, we can do this for any number! Like this:
12,345
You can also write the same number like this:
10,000 + 2,000 + 300 + 40 + 5
Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000
Examples:
12,345
The 3 in this number stands for 300, since it is in the hundreds place.
678,900
The 7 in this number stands for 70,000 because it is in the ten thousands place
Now you know!
1234 and 79 come before 65
Answer: The altitude is 4
Step-by-step explanation:
Once you know the area, you have to work backwards. I flipped the area equation to solve for height and got 2A/b = h. After that I plugged in the numbers and got an altitude of 4.
<span>The easiest way to answer any question like this is to first put your equation in the simplest form 'y = mx + b'
So in this case, f(x) = 3/4(10) - x simplifies to f(x) = 7.5 -x which reordered becomes f(x) = -x + 7.5
So if you imagine this on a graph, you'll have a point on the y axis at 7.5. Then there is a line from there at a slope of -1. So you'll have a point at (0,7.5), (1, 6.5) ... (7.5,0). Now flipping this over the x axis is easy enough. Your first point intercepting the y axis is at -7.5. Then you'll have a line going up at a slope of +1. So your new equation will simply be g(x) = x-7.5. Now simply plug any coordinate in for g(x) and x to see if the equation is true. For example, let's try (1,-6.5). So -6.5 = 1-7.5. ---> -6.5 = -6.5. So (1, -6.5) is a point on g(x)!</span>
