Answer:
7
Step-by-step explanation:
by similarity of traingles Δxuw and Δxyz
xu/xy = uw/yz
given xu+uy=xy and xu=uy
2(xu)=xy
xy=2(uy)
=>5x+4=2(4x-1)
=>5x+4=8x-2
=>3x=6
=>x=2
=>given length of uw=>4x-1=4(2)-1=7

Answer:
$20.01
Step-by-step explanation:
In 2004–2012, the interest rate is 0.002%. In 2013, it is 0.004%. In 2014–2021, the interest rate is 0.002%. That is, in the 18 years between 2004 and 2021 (inclusive), the interest rate is 0.002% for 17 of them. The effective account multiplier is ...
(1.00002^17)(1.00004^1) = 1.00038006801
Then the account balance is ...
$20 × 1.00038006801 ≈ $20.01
_____
<em>Additional comment</em>
The annual interest earned on $20.00 is $0.0004. If the account balance is rounded to the nearest cent annually, at the end of the 18 years, the balance will still be $20.00. Not enough interest is earned in one year to increase the balance above $20. At the end of the 18 years, the amount of interest earned is 0.76¢ (a fraction of a penny) <em>only if there is no rounding in intervening years</em>.
18 meters = 1800 centimeters
1 meter = 100 centimeters, so do: 18 × 100 = 1800.
