The answer is B and I am happy to help you out
Answer:
6.25%
Step-by-step explanation:
We first begin by solving for the original price of the cell phone.
if 2400 = 125%
x = 100%
By cross multplying, we get
125x = 2400 * 100
x = 240000/125
x = 1920rs
To find the profit percentage on the new sale price, we repeat another set of equations
100% = 1920
x = 2040
1920x = 2040 * 100
x = 204000/1920
x = 106.25%
His new profit percentage is 6.25%
Volume
of a rectangular box = length x width x height<span>
From the problem statement,
length = 60 - 2x
width = 10 - 2x
height = x</span>
<span>
where x is the height of the box or the side of the equal squares from each
corner and turning up the sides
V = (60-2x) (10-2x) (x)
V = (60 - 2x) (10x - 2x^2)
V = 600x - 120x^2 -20x^2 + 4x^3
V = 4x^3 - 100x^2 + 600x
To maximize the volume, we differentiate the expression of the volume and
equate it to zero.
V = </span>4x^3 - 100x^2 + 600x<span>
dV/dx = 12x^2 - 200x + 600
12x^2 - 200x + 600 = 0</span>
<span>x^2 - 50/3x + 50 = 0
Solving for x,
x1 = 12.74 ; Volume = -315.56 (cannot be negative)
x2 = 3.92 ;
Volume = 1056.31So, the answer would be that the maximum volume would be 1056.31 cm^3.</span><span>

ANSWER-
B
EXPLANATION-
log6 x^6 + 2log6 y
log6 x^6 + log6 y^2
log6(x^6 y^2)
5 - 17 = 12 so the answer is that it will be -12 degrees outside. Fahrenheit or Celsius??
