Answer: the wise man is 79
Step-by-step explanation:
400 - 3x = 163
400–163 =3x
237 = 3x or 3x = 237 or x = 79…
Answer:
49145 years
Step-by-step explanation:
In a certain country the life expectancy for women in 1990 was 45 and in 2000 it was 85?years.
Assuming that life expectancy between 2000 and 2100 increases by the same percentage as it did between 1900 and 2000,what will life expectancy be for women in 2100?
In 10 years, the expectancy increased by 85/45 = 17/9
between 2000 and 2100, it will increas by 10 time 10 years, so expected expectancy is
years
Answer:
The volume of pyramid B is 3.5 times greater than the volume of pyramid A
Step-by-step explanation:
The area of squared based a pyramid is given by:
![Area = \frac{1}{3}*s*s*h](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2As%2As%2Ah)
Where 's' the length of the side of the base and 'h' is the height.
For pyramid A:
h= 100 m
s= 356/4 = 89 m
![Area_A = \frac{1}{3}*89*89*100\\Area_A=264,033.33\ m^3](https://tex.z-dn.net/?f=Area_A%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2A89%2A89%2A100%5C%5CArea_A%3D264%2C033.33%5C%20m%5E3)
For pyramid B:
h= 215 m
s= 456/4 = 114 m
![Area_B = \frac{1}{3}*114*114*215\\Area_B=931,380\ m^3](https://tex.z-dn.net/?f=Area_B%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2A114%2A114%2A215%5C%5CArea_B%3D931%2C380%5C%20m%5E3)
Pyramid B has a greater volume and the ratio between volumes is:
![\frac{Area_B}{Area_A} =\frac{931,380}{264,033.33}\\\frac{Area_B}{Area_A} =3.5](https://tex.z-dn.net/?f=%5Cfrac%7BArea_B%7D%7BArea_A%7D%20%3D%5Cfrac%7B931%2C380%7D%7B264%2C033.33%7D%5C%5C%5Cfrac%7BArea_B%7D%7BArea_A%7D%20%3D3.5)
