Hi there
To find the simple interest earned
Use this formula
I=prt
I interest earned?
P principle 30000
R interest rate 0.05
T time 15 years
So
I=30,000×0.05×15
I=22,500
Hope it helps
Answer:
The distance between their house on the map is 10 inches.
Step-by-step explanation:
In order to calculate the distance from Jeremy's friend house to his we can apply a rule of three in a way that 60 miles is related to "x" inches in the same proportion as "1 1/2" inches is related to 9 miles. Before applying that it'll be for the best if we convert the mixed fraction to a pure fraction as shown below:

Creating the rule of three:

The distance between their house on the map is 10 inches.
Answer:
180x - x²
Step-by-step explanation:
Since the yard has 360 yd. of fencing, hence the perimeter of Rick's lumberyard has 360 yd.
Given that the yard is x yards long. Let y represent the width of the yard. Hence:
Perimeter of the yard = 2(length + width) = 2(x + y)
Substituting:
360 = 2(x + y)
180 = x + y
y = 180 - x
Therefore the width of the yard is (180 - x) yard.
The area of the yard is the product of the length and the width, hence:
Area (A) = length * width
A = x * (180 - x)
A = 180x - x²

Step-by-step explanation:
V-0.12V (first option) if we factor it it becomes
V(1-0.12)=0.88V (last option)
Answer:
132 ft²
Step-by-step explanation:
The shape is composed of a rectangle and a triangle.
Area of the shape = area of rectangle + area of triangle
Area of rectangle = L*W
L = 12 ft
W = 8 ft
Area of rectangle = 12*8 = 96 ft²
Area of triangle = ½bh
b = 8 ft
h = 21 - 12 = 9 ft
Area of triangle = ½(8*9) = 36 ft²
Area of the shape = 96 + 36 = 132 ft²
