Answer: 12/13</h3>
The sine of an angle is equal to the opposite over hypotenuse
sin(angle) = opposite/hypotenuse
sin(x) = 12/13
Expressing a number in standard form refers to the generally accepted format of expressing numbers in their ordinary form.
Large numbers written in scientific notation can be converted to standard form by writing out the numbers in full instead of raising to the power of 10.
For instance, the number 4.325 × 10³ written in scientific notation can be expressed in standard form thus :
- 4.325 × 10³
- 10³ = (10 × 10 × 10)
- 4.325 × (10 × 10 × 10) = 4.325 × 1000 = 4325
Therefore, 4.325 × 10³ is 4325 in standard form

Lets see whether the river is going against the boat or with it
speed=distance/time
22 miles per 1.5 hour
speed=22/1.5=14.66666 mile per hour
50mph>14.6666666mph
ok it slowed down, so it it going agains the current
boatspeed-currentspeed=realspeed
realspeed=14.666666mph
boatspeed=50mph
50-curretn speed=14.66666666666666
50 both sides
-currentspeed=-35.33333333333333
multiply -1
currentspeed=35.33333333333333mph
the current is 35 and 1/3mph agains the boat

V=L times W times H*V=volume W=width H=heightand you don't actually have to write times you can do the symbol.
Example- if I had a rectangular prism of the width is 5 cubes, the length 8 cubes, and the height 7 cubes(following how many gallons are in a cube 7.5) I would then use my formula. V=LWH- 8 times 7= 56 56 times 5=280 280 times 7.5= 2100V=2100 (that is your answer reply If you didn't mean the volume or you don't get it)
hope it helps :)
