Answer:
or
kilometers
Step-by-step explanation:
We want to find how many kilometers are equal to
meters.
Recall that: 
We can rewrite
as
Let 
Using proportion,
should be more than 1km.
If more, then less divides:


Therefore
meters is equal to
or
kilometers
Recall the double/half angle formulas:


We're given
, and since
is between π/2 and π, we expect
to be negative. So from the Pythagorean identity, we find

Also, we know
will fall between π/4 and π/2, so both
and
will be positive. Then we find


and it follows that

Answer:0.3273542601
Step-by-step explanation:
73÷223=0.3273542601
Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
1.) Yes they have enough flour for both of their recipes because if you find the common denominator for both of the flour cups of flour for the recipe which of course the denominator is going to be 12. so the equation would look like this 1 9/12+2 4/12. You add the mixed numbers which it makes 3 and you add the fractions which make it 13/12 you add the 1 to the 3 which makes it have enought flour. So they have 1/12 of it left over.
2.) It snowed more yesterday. It snowed 11/20 more inches. hope that helped
