If $1,000 is loaned for 5 months at 6 % annual rate, how much interest is earned?
In-s [12.5K]

Answer:

Interest earned is $25.2

Step-by-step explanation:

The formula to find simple interest is:

I = P₀rt

Where

I = interest rate

P₀ = Principal amount

r = interest rate

t= time

5 months = 5/12 years = 0.42 years

I = 1000* 6/100*0.42

I = 1000*0.06*0.42

I = 60*0.42

I = 25.2

Interest earned is $25.2

What does the initial value mean for this function?
Anit [1.1K]
She saves 10 per week.......after 4 weeks, she had 90

so if she started with nothing, after 4 weeks she would have 40.....but for her to have 90, she would have had to have started with (90 - 40) = 50.

Think about it....she starts with 50....and then saves 10 for 4 weeks giving her 40......and now she has 40 + 50 = 90

so ur answer is : Roberta had $ 50 before she started to save money each week

What is the area of the figure below?
Grace [21]

Answer:

option B

Step-by-step explanation:

The figure is combination of parallelogram and semi- circle. So,

area = area of parallelogram + area of semi-circle

Area \ of \ parallelogram = base \times height = 7 \times 6 = 42 cm^2\\\\Area \ of \ semi-circle = \frac{1}{2} \pi r^2 = \frac{1}{2} \times 3.14 \times 3.5^2 = 19.2cm^2\\\\Therefore \ Area = 42 + 19.23  = 61.2cm^2
