Answer:
F
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 5500 × 0.06 × 2.5 = 825
I = $ 825.00
The simple interest accumulated
on a principal of $ 5,500.00
at a rate of 6% per year
for 2.5 years is $ 825.00.
Answer: x - 5
Step-by-step explanation:
Since, the area of the rectangle =
Length of the rectangle = x+5
Let the width of the rectangle = b
Thus, the area of the rectangle = 
⇒ 
⇒ 
⇒ 
Therefore, the expression that shows the width of the rectangle = x-5
So percent means parts out of 100 so 17%=17/100
400 marbles
17% of 400=blue
'of' can be translated to multiply
17%=17/100
17/100 ties 400=6800/100=68
he has 68 blue marbles
