Answer:
money owed (in order): $850, $870.40, $891.29, $912.68
Step-by-step explanation:
The formula is
money owed = amount owed the previous week + amount owed previous week × interest rate (in decimal form)
so thats:
money owed = amount owed the previous week + amount owed previous week × 0.024
we can simplify that to:
money owed = amount owed the previous week x (1.024)
after 0 weeks:
$850 (just started, no interest added)
after 1 week:
$870.40
after 2 weeks:
$891.29
after 3 weeks:
$912.68

Answer:
1227 feet
Step-by-step explanation:
Let x is the the length of the base along Michigan
Given:
- The highest of the building is 28 feet less than 7 times the length of the base along Michigan
<=> The highest of the building = 7x -28
- The length of the roof is 65 feet shorter than the length of the base below it.
<=> The length of the roof = x - 65
- The area of one particular side is 149,327.5 square feet
<=> *(7x -28 ) = 149327.5
<=> (2x -65) (7x -28) = 298655
<=> - 511x = 296835
<=> x = 165.
So the building's height is: 7(165) -28 = 1227 feet
(2/5)(x-2)=4x
multily both sides by 5/2 (2/5 times 5/2=10/10=1)
1(x-2)=20x/2
x-2=10x
minus x both sides
-2=9x
divide 9
-2/9=x
