Answer: $10000
Step-by-step explanation:
From the question,
Principal = $43000
Time = 5 years
Rate = Unknown
Simple Interest = $51,600 - $43000 = $8600
We need to calculate the rate of interest which will be:
Interest = PRT/100
8600 = (43000 × 5 × Rate) / 100
Cross multiply
8600 × 100 = 215000 × Rate
Rate = 860000 / 215000
Rate = 4%
Assuming Justine borrowed $50,000 instead, the yearly Interest will be:
= (50000 × 5 × 4%)
= 50000 × 5 × 0.04
= $10000

Hello.
At the initial checkup, the baby weighed <em>160 oz. </em>At the next checkup, the baby weighed <em>180 oz. The baby increased 20 oz in weight.</em>
The formula of a volume of a cylinder:
r - radius
H - height
We have
The base of a cylinder is a circle. The formula of an area of a circle:
We need a length of a radius <em>r</em>. Therefore the correct first step in finding the area of a base of a cylinder is find the length of radius of circle in a base.
From the formula of a volume of a cylinder and given the volume and the height we have the equation:
Solve it for r:
The area of a base:
