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
Answer:
-14
Step-by-step explanation:
You've got a(1)=20
a(1) means a(n) when n=1
the sequence is telling you to take the previous value of a(n), which is a(n-1) and subtract 17
then:
a(2) = a(1)-17 = 20 - 17 = 3
a(3) = a(2) - 17 = 3-17 = -14
Answer and Step-by-step explanation:
To find the length of AB, we have to use Distance Formula.
<u>Distance Formula </u><u>takes two points on a graph, and puts it into the following formula to calculate the distance between those two points.</u>
<u />
<u>The formula:</u>
D =
<u>Where:</u>
D = The Distance between two points
= The x value of the second point
= The x value of the first point
= The x value of the second point
= The x value of the first point
Point A will be the first point and point B will be the second point. All we have to do now is plug those points into the formula and solve.
The length of side AB is units, or 11.18 units.
