Answer:
Definition: Scaled Drawing. A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount
Example
Example #1:
Suppose a problem tells you that the length of a vehicle is drawn to scale. The scale of the drawing is 1:20.
If the length of the drawing of the vehicle on paper is 12 inches, how long is the vehicle in real life?
Set up a proportion that will look like the formula above picture
A scale drawing proportion
Do a cross product by multiplying the numerator of one fraction by the denominator of the other fraction
We get :
Length of drawing × 20 = Real length × 1
Since length of drawing = 12, we get:
12 × 20 = Real length × 1
240 inches = Real length
The real length of the vehicle is 240 inches.
2)Circumference of circle: The distance around the circular region is called its circumference. The ratio of circumference of any circle to its diameter is constant. ... Area of circle: The measure of the region enclosed inside the circle is called its area.
Answer:
2yrs
Step-by-step explanation:
Given parameters:
Amount of interest earned = $40
Principal = $400
Interest rate = 5%
Unknown:
Time taken for the money to be in bank = ?
Solution:
The formula for interest is given as:
I =
Where I is the interest
P is the principal
R is the rate
T is the time
So;
100I = PRT
T = =
= 2yrs
