Answer:
800,000
Step-by-step explanation:
8 is in the hundred thousands, 1 is in the ten thousands, 1 is in the thousands, 5 is in the hundreds, 7 is in the tens, 0 is in the ones place
It rounds down as its nowhere near 900,000 which changes all its digits.
Answer:
80 students.
Step-by-step explanation:
Since there were 50 students, and 20 students wanted the chocolate icecream, that makes a proportion of 2/5. Then, there are 200 students in this whole seventh grade, and imagine that they have the same proportion of the 50 students. So, you should do 2/5 × 200, and the answer is 80.
I hope this helps you! ;)
Answer:
70
Step-by-step explanation:
![\frac{7}{8} \div \frac{1}{8} = \\ \frac{7}{8} \times \frac{80}{1} = \\ 70](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B8%7D%20%20%5Cdiv%20%20%5Cfrac%7B1%7D%7B8%7D%20%20%3D%20%20%5C%5C%20%20%5Cfrac%7B7%7D%7B8%7D%20%5Ctimes%20%20%5Cfrac%7B80%7D%7B1%7D%20%20%3D%20%20%5C%5C%2070)
Answer:
![y = \frac{5}{2}x -3](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B5%7D%7B2%7Dx%20-3)
Step-by-step explanation:
Given points (0,-3) (2, 2), we can start by solving for the slope of the line by using the formula:
![m = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
Let (x1, y1) = (0,-3)
(x2, y2) = (2, 2)
Plug in these values into the slope formula:
![m = \frac{y2 - y1}{x2 - x1} = \frac{2 - (-3)}{2 - 0} = \frac{5}{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20%3D%20%5Cfrac%7B2%20-%20%28-3%29%7D%7B2%20-%200%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D)
Therfore, the slope of the line is
.
Next, we must determine the y-intercept of the line. By definition, the y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Using the slope (m) =
and one of the given points, (2, 2), plug in these values into the slope-intercept form, y = mx + b:
y = mx + b
![y = \frac{5}{2}x + b](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B5%7D%7B2%7Dx%20%2B%20b)
![2 = \frac{5}{2}(2) + b](https://tex.z-dn.net/?f=2%20%3D%20%5Cfrac%7B5%7D%7B2%7D%282%29%20%2B%20b)
2 = 5 + b
Subtract 5 on both sides of the equation to solve for b:
2 - 5 = 5 + b - 5
-3 = b
The y-intercept (b) = -3.
Therefore, the equation of the line that passes through (0,-3) and (2, 2) is:
