We know that
surface area=area of the base+4*[area of one lateral triangle side]
area of the base=b²
b is the side length of the square
b=14 cm
area of the base=14²-----> 196 cm²
area of one lateral triangle side=b*h/2
b is the side length of the square
b=14 cm
h is the height of the lateral triangle side
h is equal to the slant height
h=15 cm
area of one lateral triangle side=14*15/2----> 105 cm²
surface area=196+4*[105]------> 616 cm²
the answer is
the surface area is 616 cm²
Answer:
Future Value = $ 12528.15
Step-by-step explanation:
The depreciation is applied to the car annually. The value of the car after depreciation in "n" no. of years can be given by the following formula:
where,
Future Value = ?
Present Value = $ 24000
Depreciation Rate = 15% = 0.15
n = no. of years = 4
Therefore,
<u>Future Value = $ 12528.15</u>
The answer is:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
So 4 dollars is discount
100-20=80 so
4 dollars =80%
1 dollar=20%
80+20=100
4+1=5
origional price=$5
