Write the exact value of, or estimate, the side length of a square with an area of 100 square units.
timofeeve [1]

Answer:

l =10 units, 9.7 units, 5.5 units

Step-by-step explanation:

Area = length x breadth

Area of a square = l^2

100= l^2

√100 =√l^2

l=10 units

95=l^2

√95 = √l^2

l= 9.7 units

30=l^2

√30=√l^2

l= 5.5 units

How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%
erik [133]
Answer:
A = $ 2,120.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation

A = 2000(1 + (0.03 × 2)) = 2120 
A = $ 2,120.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 2,000.00
at a rate of 3% per year
for 2 years is $ 2,120.00.
