The upper one is correct. Because 0,75% = 0,0075 ( :10) and since the interest rate is positive it has to be 1 + ...
A. The expression given in the question is
c = 6x + (900000/x)
c = (6x^ +900000)/x
I hope that this is the expression that you were looking for.
b. When x = 240, then
c = [6 * (240)^2 + 900000]/ 240
= (6 * 57600) + 900000/240
= (345600 + 900000)/240
= 5190
From the above deduction, it can be concluded that the cost of ordering and storing is 5190. I hope the procedure is clear enough for you to understand.
Answer:
15 miles
Step-by-step explanation:
12 + ( 1/4 x 12) = ?
12 + 3 = 15
Answer:
x = 2 ±i
Step-by-step explanation:
x^2 = 4x-5
Subtract 4x from each side
x^2 - 4x = 4x-5 -4x
x^2 - 4x= -5
Complete the square
Take the coefficient of the x term, divide by 2 and square it
-4/2 =2 2^2 =4
Add 4 to each side
x^2 -4x+4 = -5 +4
The left side is (x-coefficient of the x term/2)^2
(x-2)^2 = -1
Take the square root of each side
sqrt((x-2)^2) = sqrt(-1)
x-2 = ±i
Add 2 to each side
x-2+2 = 2 ±i
x = 2 ±i
Answer: 5:4
Step-by-step explanation:
Given : The number of convertibles = 1960
The number of minivans = 490
Total cars = 2450
The ratio of A to B can also be written as 
.
The ratio of cars to convertibles = 
![=\dfrac{2450}{1960}\\\\=\dfrac{5}{4}\ \ \ \text{[Simplest form]}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B2450%7D%7B1960%7D%5C%5C%5C%5C%3D%5Cdfrac%7B5%7D%7B4%7D%5C%20%5C%20%5C%20%5Ctext%7B%5BSimplest%20form%5D%7D)
Hence, the ratio of cars to convertibles = 5:4
