Answer:
$6.03
Step-by-step explanation:
Let's begin by listing out the given variables:
height (h) = 12 cm, diameter (d) = 8 cm, r = d ÷ 2 ⇒ r = 4 cm, cost of coconut oil (c) = $0.01 /cm³
The formula of cylinder is given by:
V = πr²h = π * 4² * 12 = <u>603.1858 cm³</u>
cost of filling the tin can with coconut oil = cost of coconut oil * Volume of cylinder
Cost = c * V = 0.01 * 603.1858
Cost = $<u>6.03</u>
-x(3+4)
If you distribute it to all the numbers the simplest form would be -3x-4x
11. x² - 7x = 0
x(x) - x(7) = 0
x(x - 7) = 0
x = 0 or x - 7 = 0
+ 7 + 7
x = 7
Solution Set: {0, 7}
12. 3x² - 4x = 20x + 27
+ 4x + 4x
3x² = 24x + 27
3x² - 24x - 27 = 0
x = -(-24) ± √((-24)² - 4(3)(-27))
2(3)
x = 24 ± √(576 + 324)
6
x = 24 ± √(900)
6
x = 24 ± 30
6
x = 4 ± 5
x = 4 + 5 or x = 4 - 5
x = 9 or x = -1
Solution Set: {9, -1}
Answer:
$300
Step-by-step explanation:
original price = $250
the profit= 15%
ok now let the cost price of article be ₹ x
x + 15% of x = 250
1.15x = 250 => 115x ÷ 100 = 250
115x = 25000 => x = 25000 ÷ 115
x = 5000/ 23
cost price of article = ₹5000/ 23
required profit = 38%
= 38% of 5000/ 23 = 0.38 × 5000/ 23
= 1900/ 23
the required will be selling price to gain about 38%
= cost price + required profit which is
= (5000/ 23) + (1900/ 23)))
= 6900/ 23 = $300
Answer: now its required selling price = $300
