Inverse variation means y=k/x (direct variation is y=kx) so we can use the info given to find the constant k
y=k/x
6=k/900
k=6(900)
k=5400 so the equation is:
y=5400/x or more accurately for this problem
t(v)=5400/v then:
t(800)=5400/800
t(800)=6.75 hours
We can find the surface area of the pyramid as
here , because the base is squre so
By putting the values of l,w and h
we get
Answer:
C
Step-by-step explanation:
It's another way of saying where the lines cross. So if the input value (x) = 1 then both lines have an output value of 1.
Answer: spread , gap, peak, cluster
Step-by-step explanation:
Just did it
Since the ratio of students with green eyes to students with blue eyes in the graph is 20/10, we can see that there is 1 blue eyed student for every green eyed student. Meaning that there will be half as many blue eyed students as green eyed students. So if there are 300 students we know that there will be 150 blue eyed students.
