= (2.2÷2) • (-3)
= 1.1 • (-3)
= -3.3
4x=16
x=4
4 times 4 is 16
74x-56=58x-1334
16x=1278
x=639/8
8900 feet = 8900/5290 miles
He walked 1.7 miles
Sin equals Opposite over Hypotenuse
Cos equals Adjacent over Hypotenuse
Tan equals Opposite over Adjacent
19000000000000 x 27%
= 190000000000 x 27
=5130000000000
Press the 2nd button and look for asin(which is for arcsin)
1500x 0.12
= 180
Area = \(8^2-4[\frac{90}{360}π(4^2)]=64-16π\)
Which is approximately 13.73m2
100/429 x 127
= 12700/429

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)
(5+6+10+6+10+6) / 6 = 43/6 = 7.1666667
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)
\(2.5d+9.25=3+3.75d \)
\(1.25d=6.25\)
\(d=5\)
e.g. 35/6 = (6*5+5)/6 = 6*5/6 + 5/6 = 5 5/6
72/5 = (5*14+2)/5 = 5*14/5 + 2/5 = 14 2/5
4^2 x 196
= 16 x 196
