The difference between 4,632 and 20,000 is 15,368
It will take 7.925 years for the population to triple.
For the steps:
The answer is 7√3 and I'll tell you why
So the first step is to break down these big numbers to find a commen number like this:
√75= 5√3
√12= 2√3
Next you will just simply add the similar elements together:
5√3 + 2√3
5+2= 7
and so 7√3 is the correct answer
Answer:
a) Surface area = 616 cm²
b) Volume = V = 1083 cm³
Step-by-step explanation:
Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm
a) Formula for surface area = Base area × 1/2(perimeter × slant height)
Base area = Base edge²
=( 16 cm)² = 256 cm²
Perimeter = Base edge × 3
= 16 cm × 3 = 48 cm
Hence:
Surface Area = 256 cm² + 1/2(48 × 15)
= 256 cm² + 360 cm²
= 616 cm²
b) Volume = 1/3 × Base area × Height
1082.758616785cm³
Approximately = 1083 cm³
The answer to 82 times 82 is 6724.
