Simply divide 61.50 by 3. You should be able to reach the answer that way

Answer:
32 months
Step-by-step explanation:
It will take Briliana twice as long to reach $16,000 as it takes to reach $8,000. Twice 16 months is 32 months to reach $16,000.
Given a slope 
, the slope 
of a line perpendicular to 
is the opposite of the inverse of
In other words:
So, the slope of CD is -5/2.
We know that
[lateral surface area of a regular triangular pyramid]=3*[area of one <span>equilateral triangle]
so
[area of one </span>equilateral triangle]=lateral surface/3-----> 81/3-----> 27 ft²
[<span>surface area of the regular triangular pyramid]=lateral area+area of the base
area of the base is equals to the area of the lateral sides because are </span>equilateral triangles
therefore
area of the base=27 ft²
[surface area of the regular triangular pyramid]=81+27----> 108 ft²
the answer is
<span>the surface area of the regular triangular pyramid is 108 ft</span>²
