Answer:
= z/12 - 1/3
Step-by-step explanation:
z-4/(4+8)
= z-4/12
= z/12 - 4/12
= z/12 - 1/3
Answer:
39
Step-by-step explanation:
3x + 12 = 6x - 15
6x - 3x = 12 + 15
3x = 27
x = 9
KJ = KH = KG = 3x + 12
KG = 3.(9) + 12
KG = 27 + 12
KG = 39
I hope I helped you.
The question is asking what is 15% of $300.
"of" means multiply, and 15% is the same as 0.15 (% means divide by 100), so you have
0.15 * $300 = $45.
If r is the radius of a sphere its surface area = 4(pi)r^2.
If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.
So the surface area becomes 4-fold or the increase in surface area is 300%.
