Daisy is not correct. The shaded part is 3/50 that of the whole circle.
<h3>Is Daisy correct?</h3>
In order to determine if Daisy is correct, the area of the circle and the area of the shaded part has to be determined.
Area of the circle = = πr²
Where :
π = pi = 22/7
r = radius = 4 + 3 + 3 = 10
10²π = 100π
Area of the shaded part = 3²π = 9π
Ratio of the areas = 9π / 100π

Ethan's mistakes in sorting the shapes into two groups are:
- Shape C does not belong to group 1 because it does not have square corners
- Shape F does not belong to group 2 because it does not have any square corners
<h3>How to spot the mistakes?</h3>
From the complete question (see attachment), the shapes are grouped using the following criteria:
- All the shapes in group 1 have 4 square corners
- All the shapes in group 2 have exactly 1 square corner
Using the above rules, Ethan's mistakes are: shapes C and F are placed in the wrong groups

Answer:
When a decimal number is multiplied by a power of ten, the product is found by moving the decimal point to the right that many places as the power of ten. For example, in 3.45 × 10 2, the product is obtained by moving the decimal point two places to the right, i.e., 3.452 × 10 2 = 345.2.

Answer:
$45.50
Step-by-step explanation:
1. $65.00 ÷ 100 = 0.65
2. 0.65 x 30 = $19.50
3. $65.00 - $19.50 = $45.50
