Answer:
225 students
Step-by-step explanation:
Total number of students = 900 students
percent that bring lunch to school everyday = 25%
Number of student that bring lunch to school = 25% of 900
Number of student that bring lunch to school = 0.25 * 900
Number of student that bring lunch to school = 225
Hence 225 students bring lunch to school everyday

Answer:
ty 4 the points lol
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
Given the following points: (-1, 4) (x, 5); and the slope (m = -1/2):
We can use the point-slope formula to find the equation of the line:

Let
= (-1, 4)
m = -1/2
Plug these values into the point-slope formula:




Add 4 on both sides:

The linear equation in slope-intercept form is:

Next, plug in the y-coordinate of the ordered pair, (x, 5) to solve for the missing x-cooridnate:


Subtract
from both sides:

Divide both sides by
to solve for x:
-3 = x
Therefore, the missing x-coordinate of the ordered pair, (x , 5) is 3.
Answer:
160
Step-by-step explanation:
To solve this we will use the equation
Distance= Velocity * Time
We will first need to calculate the time flown
So we have
960=480*time
Divide and get time=2
We now need to find the new velocity considering wind speed and we can do this by writing a new equation
We have
640=velocity*2
divide and get that velocity=320
This is the speed that the plane was going with the wind resistane which means that to calculate the wind resistance you subtract 320 from the plane's normal speed of 480
so 480-320=160
