Answer:

1249.37 units

Step-by-step explanation:

The circumference of a circle is given as

$C=2\pi \: r$

Given that the circumference of a circle is 7850 units, we can find the radius by substituting and solving for r.

$7850 = 2\pi \: r$

$r = \frac{7850}{2\pi}$

We divide to obtain:

$r = 1249.37$

Therefore the radius of the circle is 1249.37 units

For the figures shown, FHJL ~ NPRS. The scale factor applied to FHJL to create NPRS is 4 to 3.

GrogVix [38]

Remark

For every 3 units for NP will be 4 units. You can set up a proportion.

$\dfrac{3}{4} = \dfrac{45}{NP}\text{Cross Multiply}$

3*NP = 4*45

3*NP = 180 Divide by 3

NP = 180/3

NP = 60

How long will it take for a sum of 500$ attracting simple interest

Jet001 [13]

* The answer is in the explanation below*

Simple interest is calculated only on the initial amount (principal) that you invested.

Example: Suppose you give $100 to a bank which pays you 5% simple interest at the end of every year. After one year you will have $105, and after two years you will have $110. This means that you will not earn an interest on your interest. Your interest payments will be $5 per year no matter how many years the initial sum of money stays in a bank account.

-----------------------------------------------------------------------------------------

How much will an investment of $500 be worth in the future?

Initial investment: $500

Yearly deposits: $0

Interest rate: 6.00%

Years Invested: 20

At the end of 20 years, your savings will have grown to $1,604.

You will have earned in $1,104 in interest.
