2 + 7 + 2 + 7 + 2 + 7 + 2 + 7 + 2 + 7 = 45
7 = 5 + 2
10 weeks

I=prt
20=p X .05 X 5
20 = p X .25
20/.25 = p
80 = p
She started with $80
Answer:
Square. If the middle is 90° then all of them have to be.
• P is the principal amount, $3000.00.
• r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
• t is the time involved, 8 years time periods.
• So, t is 8 year time periods.
To find the simple interest, we multiply 3000 × 0.06 × 8 to get that:
The interest is: $1440.00
Answer:
Line BD can't be represent by the image.
Explanation:
Point: Point is a dot or vertex of any figure or diagram. It represent by capital alphabet. So, B would be a point.
Line: A line is a straight path with both endless. It means we can extends line from both end. But in case of BD we can't extend from point B. So, it won't be line.
Ray: A ray is straight path with one endless. It means we can't extend line from one end and extend from another end. But we can extend AC from both end. It won't be a ray.
Line Segment: A line segement is straight path with end from both end. We can't extend from either end of the line. We can say CD would be line segment.
Option 2 is correct.
