Answer:
<h2>
<u> 3.2%</u></h2>
Step-by-step explanation:
Step one:
given data
principal P= $1800
time t= 1 year
Final amount A=1857.60
rate r=?
Step two:
we are expected to solve for the rate, let assume the investment is a simple interest type.
A=P(1+rt)
solve for r we can substitute our data
1857.60=1800(1+r*1)
1857.60=1800+1800r
1857.60-1800=1800r
57.6=1800r
r=57.6/1800
r=0.032
0.032*100= 3.2%
<u>This shows that the rate is 3.2%</u>
Answer:
5
Step-by-step explanation:
A number by itself is a constant.
Answer:
I'm not sure cause their are no statements!
Step-by-step explanation:
None!
<h3>
First Method:</h3>
<u>Using cosine rule</u>:




<h3>
Second Method:</h3>
<u>First find XY using sine rule</u>:



Then use Pythagoras Theorem:
⇒ XY² + YZ² = XZ²
⇒ (6)² + YZ² = 12²
⇒ YZ² = 144 - 36
⇒ YZ = √108
⇒ YZ = 6√3
⇒ YZ = 10.4
2/10 is the same at 20/100 (because you times both top and bottom by 10)
20/100 + 4/100 = 24/100
This could be simplified to 12/50 or 6/25.
Hope this helps :)
