Question

1. (20) in a division problem, if the divisor is 3 and the quotient is 9, then what is the dividend?
2. (28, 35) what year was five centuries before 1500?
3. (53) if the radius of this circle is 12 millimeters, then what is the diameter of the circle?

(image of a circle with radius labeled 12 mm)

Explanation:

Question 23

Step1: Recall division formula

In division, \( \text{Dividend} = \text{Divisor} \times \text{Quotient} \).

Step2: Substitute values

Given divisor \( = 3 \), quotient \( = 9 \). So, dividend \( = 3 \times 9 = 27 \).

Step1: Understand century to years

1 century = 100 years, so 5 centuries = \( 5 \times 100 = 500 \) years.

Step2: Subtract from 1500

To find 5 centuries before 1500, calculate \( 1500 - 500 = 1000 \).

Step1: Recall diameter formula

The diameter \( d \) of a circle is related to radius \( r \) by \( d = 2r \).

Step2: Substitute radius value

Given \( r = 12 \) mm, so \( d = 2 \times 12 = 24 \) mm.

Answer:

27
