The angle whose tan = 0.3057. ( You use the tan-1 key on your calculator)
Z = 17 degrees
1 kilogram= 1,000 grams
2 kilogram= 2,000 grams
3 kilogram= 3,000 grams
4 kilogram= 4,000 grams
5 kilogram= 5,000 grams
6 kilogram= 6,000 grams
7 kilogram= 7,000 grams
If 1 kilogram equals 1,000 grams then, half kilogram equals 500 grams.
7.5 kilograms= 7,500 grams
From the equation we have :
-3x-5y=-15-3x-3y <=> -5y = -15-3y<=> 15= 5y-3y <=> 2y= 15 <=> y=15/2
We also have:
-3x-5y =-3. Given y= 15/2 => -3x -5(15/2)=-3 <=> -3x = -3x +5(15/2) = 34.5 <=> x = 34.5/3 =23/2 = 11.5
Answer:
Select all the lines with slope 
.
Step-by-step explanation:
Use the slopes to help you answer this kind of questions.
The slope of the line going through: (1, - 2) and (3,4) is given by:
We plug in the coordinates to get:
All lines that are perpendicular to this line has slope .
