Answer:
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a square, which is:
Where s is the lenght of a side of the square.
2. By definition, the sides of the square have equal lenghts. You can calculate the lenght of a side by calculating the distance between two vertices of the aquare:
Where is the lenght of the side AB.
3. The area is:
Answer:
- after 4.5 months (or 5)
- $795
Step-by-step explanation:
10% of $100 per month is $10 per month.
1. By saving $10 per month on insurance cost, Dan's savings after 4.5 months will be equal to the $45 cost of his course. (If billing is monthly, he won't experience any net gain from the course until the 5th insurance payment--after 5 months.)
__
2. In 7 years, the savings on insurance costs will total ...
(7 years)×(12 months/year)×($10 /month) = $840
His cost for the course is $45, so his net saving is ...
$840 -45 = $795 . . . net saving by age 25
Answer:
5
Step-by-step explanation:
1 crystal can raise 12 zombies
x crystals can raise 60 zombies
This is a problem involving <em>ratio-and-proportion</em>.\
1/x = 12/60
Reduce the fraction to lowest terms 1/x = ⅕
Multiply each side by x 1 = x/5
Multiply each side by 5 x = 5
Lilliana needs five dark power crystals to raise 60 zombies.
Answer:
h ≈ 6
Step-by-step explanation:
Using the formula:
Or:
We can rearrange to make h the formula:
h= 3 (64/3.14×3.2²)
h = 3(64/3.14×10.24)
h=3(64/32.1536)
h=3(1.99044585987)
h= 5.97133757962
h ≈ 6
