Either a student passes an exam or fails it. that means the percentage of students who pass plus the percentage of students who fail must add to 100%. this also means that if 22% pass, then 78% fail. there are 68 students total and 78% fail so the number of students failing is:
(78/100)(68) = 53.04 which is approximately 53 students.
let me know if you have any questions!!!!
Speed: distance traveled in a given time
y=distance ( given in miles).
x = time (given in minutes)
Speed = y/x
y = 39.4x
By rearranging this y/x =39.4 ( is the constant speed). don’t forget this is mile/minutes
There are 4 x 60 minutes in 4 hours
Hence, you are asked the distance (y) in 240 min
y = 39.4x
y = 39.4 miles/minutes x (240) minutes
y = 9456 miles
Answer:
1/3 times x squared divided by 4 times pi times x.
Step-by-step explanation:
Hope this helps!
Please find the attachment.
Let x represent the side length of the squares.
We have been given that an open box is made from an 8 by ten-inch rectangular piece of cardboard by cutting squares from each corner and folding up the sides. We are asked to find the volume of the box.
The side of box will be 
and 
.
The height of the box will be 
.
The volume of box will be area of base times height.
Now we will use FOIL to simplify our expression.
Now we will distribute x.
Therefore, the volume of the box would be .
