Answer:
Step-by-step explanation:
20,000 students 50% are accepted so that is 10,000 students of that 10,000 only 25% enroll which is 2,500.
I think it’s A But I’m not sure
Let m and r represent the maximum speeds of Malcolm and Ravi in km/h, respectively.
... (m + r)/2 = 260 . . . . . the average of their speeds was 260 kph
... 2m = r + 80 . . . . . . . . double Malcolm's speed is 80 kph more than Ravi's
The second equation can be solved for r and that expression substituted into the first equation.
... 2m - 80 = r . . . . . . . . . . . an expression for r from the second equation
... (m + 2m - 80)/2 = 260 . . . the result of substituting that into the first
... 3m - 80 = 520 . . . . . . . . multiply by 2
... m = 200 . . . . . . . . . . . . . add 80 and divide by 3
... 2·200 - 80 = r = 320 . . .substitute the value of m into the expression for r
Malcolm's maximum speed was 200 km/h.
Ravi's maximum speed was 320 km/h.
Given:
The railing will begin at a height of 36 inches.
Height decreases 9 inches for every 12 horizontal inches.
To find:
The function for this situation.
Solution:
Let y be the height of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs.
Initial height = 36
So, y-intercept is 36.
Height decreases 9 inches for every 12 horizontal inches. So,
![\text{Slope}=\dfrac{\text{Vertical change}}{\text{Horizontal change}}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%7D%3D%5Cdfrac%7B%5Ctext%7BVertical%20change%7D%7D%7B%5Ctext%7BHorizontal%20change%7D%7D)
![m=\dfrac{-9}{12}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B-9%7D%7B12%7D)
![m=-\dfrac{3}{4}](https://tex.z-dn.net/?f=m%3D-%5Cdfrac%7B3%7D%7B4%7D)
Slope intercept form of a line is
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Substitute
and b=36.
![y=-\dfrac{3}{4}x+36](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B3%7D%7B4%7Dx%2B36)
The required function is
.
Therefore, the correct option is A.
