18/72=(ar^-2)/(ar^-4)

1/4=r^2

r=(1/4)^(1/2)

r=1/2

18=a(1/2)^-2

18=4a

9/2=a

y=(9/2)(1/2)^x

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.

The sum of three numbers is 26. The second number is twice the first and the third number is 6 more than the second. Find the nu
vampirchik [111]

ANSWER

4,8,14

EXPLANATION

Let the first number be

x

Then the second number will be

2x

and the third number is

2x + 6

The sum of these numbers is 26.

This implies that;

x + 2x + (2x + 6) = 26

Group similar terms;

x + 2x + 2x = 26 - 6

Simplify;

5x = 20

Divide both sides by 5

x =  \frac{20}{5}

This gives us;

x = 4

The numbers are:

4,8,14
