Answer:

C:protractor

Step-by-step explanation:

A compass is needed to draw arcs that are used to determine the position of the perpendicular bisector

A pencil works hand in hand with the compass

A straightedge is used to draw straight line that will be the bisector.

Note that a protractor is used to measure angles and not to construct angles.

$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
