Answer:
C
Step-by-step explanation:
If we have 5 packages and each contains 80, we are basically doing 80+80+80+80+80 (5 TIMES) which is referred to as 80×5=400
Answer:
Step-by-step explanation:
sec(theta) is defined as: 
In the diagram you provided the hypotenuse of the triangle is sqrt(41) and the opposite side is 5, using these two sides, we can solve for the adjacent side by using the Pythagorean Theorem: 
So this gives us the equation where a=adjacent side:
Subtract 25 from both sides
Take the square root of both sides
So now plug this into the definition of sec(theta) and you get: . This is in most simplified form since 41, has no factors besides 41 and 1.
We need to solve the equation: w² + 36 = 12w
⇒ w² - 12w + 36 = 0
⇒ w² - 6w - 6w + 36 = 0 (Breaking 6w such that their product is 9w²)
⇒ w × (w - 6) - 6 × (w - 6) = 0 (Extracting common factors)
⇒ (w - 6) × (w - 6) = 0
⇒ (w - 6)² = 0
⇒ w = 6
Hence, the correct answer is 6 which is the fourth option from the replacement set
Answer:
2000 units
Step-by-step explanation:
u = units sold
p = selling price
c = unit cost
Revenue = u × p
Costs = fixed costs + (c × u)
Profit = revenue - costs
Revenue = 10 × u
Revenue = 10u
Costs = 10000 + (5 × u)
Costs = 10000 + 5u
Breakeven means profits = 0:
Profits = 10u - (10000 + 5u) = 0
10u - 10000 - 5u = 0
5u - 10000 = 0
5u = 10000
u = 2000
