sin(size of angle) = opposite / hypotenuse
Therefore opposite = hypotenuse x sin(size of angle)
cos(size of angle) = adjacent / hypotenuse
Therefore adjacent = hypotenuse x cos(size of angle)
7.9*10^10
√144 = 12
Percentage of Fresh water = 100%-6.1% = 93.9%
3.4*10^6*93.9%
= 3192600
There are 3192600 gallons of fresh water
Let x ft be the distance a person travels on the escalator stairs.
sin35 = 84/x
x = 84/sin35 ≈ 146.45
A person travels 146.45ft on the escalator stairs.
1.65x+120*200 = 1.65x+24000
0.06y+200=0.03y+350
6y+20000=3y+35000
3y=15000
y=5000
\(\frac{(-2mn^2)^3}{4m^{-6}n^4}\)
\(= \frac{-8m^3n^6(m^6)}{4n^4}\)
\(= -2m^9n^2\)
There are 12 sides in a cube
5 cube = 12 sides x 5 with each 5cm each side.
therefore perimeter
= 12 x 5 x 5
= 300 cm
(= 3 meters)
\(2.5d+9.25=3+3.75d \)
\(1.25d=6.25\)
\(d=5\)
