In 6 months, Simple interest of $6 will be earned for investing $100.
<u>Step-by-step explanation:</u>
Step 1:
Given details are Principal (P) = $100, SI rate (R) = 12%, Time (T) = 6 months = 0.5 years
Step 2:
Calculate Simple Interest by the formula SI = PRT/100
⇒ SI = 100 × 12 × 0.5/100
⇒ SI = $6
Step-by-step explanation:
Length of rectangle = 4 * 3.5cm = 14cm.
Perimeter of rectangle = 2(14 + 3.5) = 35cm.
Area of rectangle = 14 * 3.5 = 49cm².
Distance to travel = 20 m.
Let us determine the time, t, that each participant took to complete 20 m.
Barbara:
Average speed = (3 m)/(2 s) = 1.5 m/s
t = 20/1.5 = 13.3 s
Mark:
t = 5 s
Carlos:
y = x + 1
where
y = 20 m
x = time, t
Therefore
t =x = y - 1 = 20 - 1 = 19 s
Summary:
Barbara: 13.3 s
Mark: 5 s
Carlos: 19 s
Answer:
The winner is Mark
