Answer:x=13
BMC=75 degrees
Step-by-step explanation:
（x+2）+（5x+10）=90 degrees
so 6x+12=90
x=13
5x+10=5x13+10=75 degrees
8/97 = 12/x.....8 oz to 97 mg = 12 oz to x mg
cross multiply
(8)(x) = (97)(12)
8x = 1164
x = 1164/8
x = 145.5 (or 145 1/2) mg
Answer:
dx/dy = (x^4 - 2x^5y - 6xy^2) / (5x^4y^2 - 4x^3y + 2y^3).
Step-by-step explanation:
x^5y^2 − x^4y + 2xy^3 = 0
Applying the Product and Chain Rules:
y^2*5x^4*dx/dy + 2y*x^5 - (y*4x^3*dx/dy + x^4) + (y^3* 2*dx/dy + 3y^2*2x) =0
Separating the terms with derivatives:
y^2*5x^4*dx/dy - y*4x^3*dx/dy + y^3* 2*dx/dy = x^4 - 2y*x^5 - 3y^2*2x
dx/dy = (x^4 - 2x^5y - 6xy^2) / (5x^4y^2 - 4x^3y + 2y^3)
All you have to do is find 40% or .4 of 90.
90 x .4 = 36
36$ is the mark up, so the total price would be 126$.
