You need to apply Law of Sine:

DE/sinC = CD/sinE

Since sinC = sinE

Then DE = CD = 7.06

25% of 60 to 40% of 30<br> >, < or =

Travka [436]

You can reduce the percentages to fractions:

$25\% = \dfrac{25}{100} = \dfrac{1}{4}$

$40\% = \dfrac{40}{100} = \dfrac{2}{5}$

So, we have

$25\% \text{ of } 60 = \dfrac{1}{4}\cdot 60 = 15$

$40\% \text{ of } 30 = \dfrac{2}{5}\cdot 30 = 12$

How long will it take to sum of 6,000 naira to give an interest of 1500Naira at 5% rate

Sonja [21]

Answer:

5years

Step-by-step explanation:

Interest=Principal*Rate*Time/100 which is

I=P*R*T/100

1500=6000*5*T/100
1500=30000/100*T
1500=300T
1500/300=T
5=T

Therefore T which is Time=5 years.
