Answer:
Step-by-step explanation:
first off, let's convert the mixed fractions to improper, and then do the sum.
Answer:
∠ABD=150°
Step-by-step explanation:
6c+12+51-c=178
5c=178-12-51
5c=178-63=115
c=115÷5=23
∠ABD=6c+12=6×23+12=138+12=150°
Answer:
Rate of interest = 99.99%
Step-by-step explanation:
The computation of the rate of interest is shown below:
Given that
The amount after 5 years is 10,000
And, after 8 years it is 15,000
so for 3 years, it is
= 15000 - 10000
= 5000
Now the simple interest for one year
= 5000 ÷ 3
And, for five years, its is = 5000 ÷ 3 × 5
= 8333.33
Now the principal amount is
= 10,000 - 8333.33
= 1666.67
Now finally the rate of interest is
8333.33 = 1666.67 × Rate of interest × 5
Rate of interest = 99.99%
