Answer:
5 pt
Step-by-step explanation:
We know that
A direct variation is a<span> mathematical relationship between two variables that can be expressed by an equation
</span>y=kx
the rate of change is equal to the slope of a line
k=m
step 1
Find the slope of the graph
let
A(0,0)
B(10,50)
m=(y2-y1)/(x2-x1)------> m=(50-0)/(10-0)------> m=50/10-----> m=5
therefore
the equation is
y=5x
the answer is
the rate of change is 5
3400/60 = 56.6666 minutes/60 = 0.94 hours
63360/5280 = 12 miles
12/0.94 = 12.76 miles per hour for Nina
Nina is faster
A percentage is a ratio with a comparison to 100. So if you were writing it out it would be
X:100 or X/100
Since we have
pink:white = 1:5 or 1/5 all we have to do is multiply by a number that will give us 100 in the denominator.
1/5 × 20/20 = 20/100
20/100 = .20 = 20%
The bag contains 20% pink marbles.
Answer:
7
Step-by-step explanation:
The median is the number in the middle of a data set.
For example, in this question 7 is in the middle of the data set, thus making it the median.
