Answer: x=-0.4
Step-by-step explanation:
Answer:
What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000
To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000
A = w(2w + 3)
90 = 2w^2 + 3w
2w^2 +3w - 90 = 0
(w-6)(2w+15) = 0 (TRINOMIAL FACTORING)
w = 6 inch ( it can't be -15/2 because lengths can't be negative)
l = 2w + 3
= 15 inch
The volume of a cylinder is pi*r^2*h
The radius is half the diameter, so 40/2=20, and the radius is 20 ft.
Plugging in: pi*20^2*32=pi*400*32=12800pi=40212.38597
So the volume is about 40212.4 ft^3 and the expression we used is pi*20^2*32
Hope this helped!
Answer:
x can be any value
Step-by-step explanation:
(5^0)^x = 1,
5^0 =1
1^x =1
X can be any value
