The cost to equip all the stations in the chemistry lab is calculated as: $393.75.
<h3>How to Calculate Total Cost?</h3>
In this scenario, we are given the following:
Total number of stations = 21 stations
Length of rubber tubing each of the stations in the chemistry lab needs = 5 feet
Total length of rubber tubing needed for all stations in the chemistry lab = 21 × 5 = 105 feet
Cost of 1 rubber tubing = $6.25 per yard
Convert 5 feet to yard:
1 yard = 3 feet
x yard = 5 feet
x = (5 × 1)/3
x = 5/3 feet.
So, the cost of 1 rubber tubing = $6.25 per 5/3
Cost of total length of tubbing needed = (105 × 6.25)/5/3 = (105 × 6.25) × 3/5
Cost of total length of tubbing needed = $393.75
Therefore, the cost to equip all the stations in the chemistry lab is calculated as: $393.75.

#SPJ1
According to the 55 m/min speed, in 3 minutes, he should have traveled 165 m.
Since he only went 135 m, that means the water moved against him for 30 m. That also happened in 3 min so the water is moving against him at 10m/min.
Step-by-step explanation:
it's late but I hope it helps :)
imagine that the > symbol is just an equal sign
so for example
x+2>4
will look like
x+2=4
and you solve normally
×=2
now we bring the symbol back
x>2
but if you multiple or divide by a negative the sign flips
so say you have
-2x>4
make it into
-2x=4
solve
x=-2
but instead of >
you put
x < -2
Answer:
y = 3x + 2
There slope is 3 and intercept is 2.
<u>First find what are the 2 pair that given by slope =3</u>
First consider A. (3, 11) and B. (3, 9)
Tan α = \fraction(11-9)(3-3)
It is undefine.
Next consider A. (3, 11) and BC (5,15)
Tan α = \fraction(15-11)(5-3)
=2
Next consider A. (3, 11) and D. (2,4)
Tan α = \fraction(11-4)(3-2)
=7
Next consider B (3, 9) and C. (5,15)
Tan α = \fraction(15-9)(5-3)
=3
So this is ordered pair is generated from slope =3
