Answer:
400 ping pong balls
Step-by-step explanation:
Let the total number of ping pong balls =x
Out of x ping pong balls, 80 are marked with a blue dot
Out of 80 ping pong balls, 16 are marked with a blue dot.
Expressing it as a ratio:
x:80=80:16
There are an estimate of 400 ping pong balls in the container.
Answer:
y = -x - 1
y = 1.5x + 6
(-3, 2)
Step-by-step explanation:
y = mx + b
y-intercepts are plotted on the graph
slope = rise over run
Solution is plotted on the graph
Answer:
it
Step-by-step explanation:
i + t = it
Answer:
Sorry
Step-by-step explanation:
Where are the answer of the four students?
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
