The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.
Given :
- A store sells laptops for 720 each.
- This price is 20 percent more than what it cost the store to buy each of them.
- Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.
The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:
Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.
Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:
= 600
Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.
Step 4 - So, the total cost of the laptop at which an employee purchase is:
= 462

Answer:
180 points.
Step-by-step explanation:
Given:
A class will have 1 test and 5 homework assignments to complete.
The test is worth 80 points.
Each homework assignment is work 25% of the test.
Question asked:
How many points may be earned during this unit ?
Solution:
By unitary method:
Points may be earned from 1 assignments = (given)
=
Points may be earned from 5 assignments =
Points may be earned from 1 test =
Total points may be earned = 100 + 80 = 180
Therefore, 180 points may be earned during this unit.
If we consider "a" as the edge length, and "D" the cube's diagonal, we have that the square cube's diagonal is equal to the edge length's square plus the side diagonal (d) square (Pythagoras theorem)
a² + d² = D²
And since:
d² = a² + a²
Clearing a, we have:
a² = D²-d²
<span>a² = D²-2a²
</span><span>3a² = D²
</span>
a = √(<span>
D²/3)</span>
Surface area is equal to 6·a², so the surface area will be 6·(D²/3) =
2D²The volume is a³, so the volume will be √(D²/3)³ = √
(<span>/3</span>³<span>) =
D</span>
³/√27
