The area of plate which is covered by the napkin is equal to the area of folded napkin.
Before finding the area of folded napkin, we should find the dimension of the napkin.
Find the length of the leg side, the two leg has similar length.
perimeter = 38
l + l + 8 = 38
2l + 8 = 38
2l = 30
l = 15
Each leg is 15 cm long.
Find the area of folded napkin
area = 1/2 × s × s × sin of angle between the sides
area = 1/2 × 15 × 15 × sin 30°
area = 1/2 × 15 × 15 × 1/2
area = 225/4
area = 56.25
to the nearest whole number >> 56 cm²
The answer is third option
The Greatest Would Be 89.100
The perimeter of the square is 48
There are 4 equal-length sides to the square, making each side 12 in. in length
to find the area, multiply two sides of the perimeter
12 x 12 = 144
Perimeter: 48
Side: 12
Area: 144
hope this helps
Answer:
Now that his car is 5 years old, he would like to know whether the variability of gas mileage has changed. He recorded the gas mileage from his last eight fill-ups; these are listed here. Conduct a test at a 10% significance level to infer whether the variability has changed.
Step-by-step explanation:
If you would like to know how much did the shirt cost after 6% tax, you can calculate this using the following steps:
6% of $43 = 6/100 * 43 = $2.58
$43 + $2.58 = $45.58
The correct result would be $45.58.
