Answer:
When making a major purchase, first determine your <u>net
</u> income by subtracting the deductions from your gross pay.
Explanation:
In business and accounting, net income is an entity's income minus cost of goods sold, expenses and taxes for an accounting period.
Answer:
The break-even point in units for ordinary laptops is 2,100 units.
Explanation:
Contribution Margin per unit (ordinary) = Selling Price - Variable cost
= $650 -$605
= $45
Contribution Margin per unit (premium) = Selling Price - Variable cost = $1,150 -$1,090
= $60
$45* 4x + $60x = Fixed Costs = $126,000
= 180x +60x = $126,000
=240x =$126,000 = 525 units
Ordinary computers = 4x
= 4*525
= 2,100 units
Therefore, The break-even point in units for ordinary laptops is 2,100 units.
The dimensions of the cylinder can be used to minimise cost of manufacture.
<h3>How to we find minimised cost?</h3>
Let's ignore the metal's thickness and assume that the material cost to manufacture is precisely proportionate to the surface area of a perfect cylinder.
A=2πr(r+h)
Given that V=1000=r2h and h=1000=r2, we can write
A=2πr(r+1000πr2)
A=2πr2+2000r−1
By setting the derivative to zero, we may determine the value of r that minimises A:
A′=4πr−2000r−2
0=4πr−2000r−2
2000r−2=4πr
2000=4πr3
r=500π−−−√3
r=5.419 + cm
h=1000πr2=10.838 + cm
The can with the smallest surface area has a volume of 1000 cm 3 and measures 5.419+ cm in radius and 10.838+ cm in height. The can has a surface area of 553.58 cm 2. Given a constant volume, the cylinder with diameter equal to height has the least surface area.
Can surface area (cm2) versus. radius (cm), where capacity = 1000cm 3.

Answer:
roles of government
Explanation:
The government uses part of the taxes it collects to provide public goods such as goods as education, healthcare, and infrastructure. In mixed economies such as the US, the government's main role in the economy is to ensure fair competition among suppliers and protect consumers' and workers' rights.
The government has established several bodies and mandated them to carry out the regulatory functions. Different agencies regulate different trade sectors such as communication, drugs and medicines, weights and measures, employees' safety and health, etc.
