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.

ANSWER
EXPLANATION
Let the first number be
Then the second number will be
and the third number is
The sum of these numbers is 26.
This implies that;
Group similar terms;
Simplify;
Divide both sides by 5
This gives us;
The numbers are:
The answer is the slope is -3/2!
The answer is 7 because 70 ÷ 10 = 7.
Answer:
870
Step-by-step explanation:
the equation is S=30w+450
to find the answer just replace the w by 14
multiply 30 by 14 to get 420 and add 450 to it to get 870
