Elisa has 6 1/4 pounds of flour. She would like to divide the flour equally into 5 bags. How much flour will be in each bag? 1 1
Lera25 [3.4K]

Answer:

1 1/4

Step-by-step explanation:

All this is, is division. You do 61/4 dived by 5. To divide fractions you flip the numerator and denominator of the second number and multiply them.

25/4 *1/5

Therefore the answer is 25/20 which is 1 and 5/20

That can be simplified to 1 and 1/4.

Convert r =-72/12+6 sin theta to Cartesian form.
PolarNik [594]
For converting polar to cartesian form we know
r =  \sqrt{x^2 + y^2}
x = rcos \theta , y = rsin \theta

Given equation is

r =  \frac{-72}{12} + 6sin \theta

We can simplify it as
r = -6 + 6sin \theta

Now we can write it as
r^2 = -6r + 6rsin \theta

Now we can use
r^2 = x^ 2+ y^2 , rsin \theta = y , r =   \sqrt{x^2 + y^2}
So equation we can write it as
x^2 + y^2 = -6 \sqrt{x^2 + y^2} + 6y
x^2 + y^2 - 6y = -6 \sqrt{x^2 + y^2}
On squaring both sides
(x^2 + y^2 - 6y)^2 = (-6 \sqrt{x^2 + y^2})^2
x^4 + y^4 + 36y^2 +2x^2y^2 -12y^3 -12x^2y = 36(x^2 + y^2)
x^4 + y^4 +36y^2 + 2x^2y^2 -12y^3 -12x^2y = 36x^2 + 36y^2
x^4 + y^4 + 36y^2 +2x^2y^2 -12y^3-12x^2y - 36x^2 - 36y^2 = 0
x^4 + y^4 -12y^3 + 2x^2y^2 - 12x^2y - 36x^2 = 0

It wants me to find m∠2 from this
yulyashka [42]

Answer:

Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°
