< 3 and <6 are same side interior angles and

they are supplementary angles (they add up to 180°)

m<3 = 41°

m<6 = 180-41= 139°

<6 and <8 are vertical angles and vertical angles are congruent

(they have equal measures)

m<6 = 139°

m<8 = 139°

$700 is invested at 4% per annum. How long will it take for the amount to reach $784?

Blababa [14]

Answer:

3yrs

Step-by-step explanation:

Given parameters:

Capital = $700

Percentage interest = 4% per annum

Unknown:

Time it will take for amount to be = $784

Solution:

To find the simple interest on an amount;

I = $\frac{PRT}{100}$

P is the principal

R is the rate

T is the time

I is the interest

Insert the parameters:

I = $\frac{700x 4 x T}{100}$

I = 28T

So;

At the end of the duration:

Principal + Interest = Amount

700+28T = 784

28T = 784 - 700

28T = 84

T = 3yrs
