2 + -9n = 56. -9n = 54. N = -6
In order to make this equation true you would have to add to it if you want w to equal 12. As it stands the equation would work out as follows...
7w = 87
w = 87/7
w = 12 3/7
As you can see 12 3/7 does not equal 12. The answer is 12 with 3 left over, so to make the equation true with w remaining 12, we have to take those 3 extras away by changing the problem...
7w + 3 = 87
7w = 87 - 3
7w = 84
w = 84/7 = 12
A 75% increase followed by 33.33% goes under less than the original
A 30$ increase followed by a 30$ decrease goes under same as the original
A 55% decrease followed by 25% increase goes under greater than the original
100% increase followed by a 50% decrease goes under less than the original
20% decrease followed by a 40% increase goes under greater than the original
Answer: 8π square meters
Explanation:
First, we convert the angle of the sector to radians, which is 30 degrees.
Note that 180 degrees is equal to π radians. Since 30 degrees is equal to 180 degrees divided by 6,
30 degrees = π/6 radians
Thus, the angle of the sector in radians is π/6.
So, the area of the sector is given by
(Area of sector) = (1/2)(radius)²(angle of the sector in radians)
= (1/2)(radius)²(π/6)
= (π/12)(radius)²
= (1/12)(π)(radius)²
Note that
(Area of the circle) = (π)(radius)² = 96π
Therefore, the area of the 30-degree sector is given by
(Area of the sector) = (1/12)(π)(radius)²
= (1/12)(Area of the circle)
= (1/12)(96π)
(Area of the sector) = 8π square meters
Okay the first one is : -2x^4/3y^3
and the second one is : y^7/x^4
the “^” are because i cant put them up so they’re exponents !
