Pythagoras theorem ! (a²+b²=c²)
Q1) AC = √4.8²+3.6²
= √36
= 6cm
Q2) AB= √17.55² - 6.75²
= √262.44
= 16.2cm
Q3) BC= √14² - 6²
= √160
= 12.64911
= 12.6 cm (to 3sf)
Answer:
$215,892.50
Step-by-step explanation:
This is a problem of compound interest.
In compound interest Amount A for principal p charged at interest r% per annum is given by
A = p(1+r/100)^n
where n is the time period in years.
_____________________________
given
p = $100,000
r = 8%
t = 10 years
A= 100,000( 1+ 8/100)^10
A= 100,000( 1.08)^10
A = $215,892.50
So , you need to pay $215,892.50 in total to debt cleared of debt.
Rounding is simple:
- If the previous digit is 5-9, round the number to the left of it up a number. If it is 4-0, leave the number to the left of it as it is.
For 82.98, we can round 82 to 83, since 82 is the whole number and the previous digit is 9 (so we round up).
For 169.645, we scratch off 45. Since 6 is in the tenth's place and the previous digit of it is 4, we leave it at 169.64.

Hey! just so you know you put it upside down but the answer is 23.
Retention ratio = (net income - dividends) / net income
retention ratio = (20,000 - 6000) / 20000 = 14,000/20,000 = 0.7 = 70%
