Answer:
they paid a total of 590.49
Step-by-step explanation:
1000 / 10 = 100 dollar discount he pays 900
900 / 10 = 90 they got a 90 dollar discount 810
810 / 10 = 81 they got an 81 dollar discount 729
729 / 10 = 72.9 they got a 72.9 dollar discount 656.1
656.1 / 10 = 65.61 they got a 65.61 dollar discount 590.49
Answer:
-3 b + 16
Step-by-step explanation:
Simplify the following:
-3 (b - 3) + 7
-3 (b - 3) = 9 - 3 b:
9 - 3 b + 7
Grouping like terms, 9 - 3 b + 7 = -3 b + (9 + 7):
-3 b + (9 + 7)
9 + 7 = 16:
Answer: -3 b + 16
Answer:
<h2>
The value of x is 2√2</h2>
Step-by-step explanation:
Use trig (specifically, the sine function) to find the length of JL:
Since sin Ф = opp / hyp, opp = hyp·sin Ф.
Here, opp is the length of JL and is found as follows:
|JL| = 8√2·sin 30° = 8√2·(1/2) = 4√2
Note that this 4√2 is the length of the hypotenuse of the smaller triangle.
Applying the definition of the sine function again:
x = hyp· sin Ф, and with hyp = 4√2 and Ф = 45°, we have:
x = (4√2)(1/2) = 2√2
The value of x is 2√2
Answer: 2x - $1000
<u>Step-by-step explanation:</u>
Initial investment: x
First Month: x - $500 <em>because she lost $500</em>
Second Month: 2(x - $500) = 2x - $1000 <em>because she double her money from the end of the first month.</em>
