Answer:
Your answer would be A
The site Math-way is a good tool for this
Answer:
3:1
Step-by-step explanation:
240 necklaces in one month
180-sold on website
60- sold in shop
180:60
then you would simplify
so the final answer is 3:1
14 = 7*2
63 = 7*9
14 7 * 2 2 2
---- = ------- 7/7 =1, so = 1 * ------ = ----
63 7 * 9 9 9
There is no image posted. However, I will tell you how to solve for the area of a drum head.
Drum head is a circle shape. We will use the formula of finding the area of a circle to solve for the area of a drum head.
Area of a circle = π r²
π is pi. It is equivalent to 3.14. Though there are still a lot of numbers after 4. To ensure uniformity, π is 3.14
r is radius. It is the line from the center of the circle to the edge of a circle.
if the diameter of a circle is given, simply divide the diameter by 2 to get the radius.
Diameter is the line that starts from one end of the circle to the other passing through the midpoint of the circle.
Example:
The drum head has a diameter of 10. What is the area.
diameter is given, so we need to get the radius: 10 ÷ 2 = 5
Area = π r²
= 3.14 * 5²
= 3.14 * 25
Area = 78.50 square unit
Area is always in a square unit.
