The amount of metal he will need to cover the back of the shelves is 180 inches².
The figure above is like a composite figure. Therefore, lets find the area.
<h3>Area of the composite figure</h3>
The area of the figure is the sum of the whole individual 2 dimensional shapes in the composite figure.
Therefore, two rectangles can be drawn from it.
area of rectangle = lw
where
l = length
w = width
Therefore,
area of rectangle 1 = 9 × 8 = 72 inches²
area of rectangle 2 = 6 × 18 = 108 inches²
Total area = 108 + 72 = 180 inches²
Therefore, the amount of metal he will need to cover the back of the shelves is 180 inches².

Answer:
80°, 40° and 60°
Step-by-step explanation:
Name the second angle X and the first angle to 2X (because it is twice the measure of angle number two) and the third angle to 20°+X (because it was 20° more than the second angle)
so we will have an equation of
180°=2x + x + (20°+x)
160°=4x
40°=x
so the second angle is 40° as it is represented by just one X
therefore the first angle which is twice the measure is 80° and the third angle which is 20° more is 60°. hope that helps!
Answer:
B
Step-by-step explanation:
Write a five-number summary for each distribution:
<u>Bulldogs:</u>
Min: 55
Q1: 70
Med: 80
Q2: 90
Max: 105
This distribution is symmetric, because Q1-Min=Max-Q2=15 and Med-Q1=Q2-Med=10
Tigers:
Min: 55
Q1: 60
Med: 65
Q2: 85
Max: 110
This distribution is not symmetric, because Q1-Min=15, Max-Q2=25 (15≠25) and Med-Q1=5, Q2-Med=20 (5≠20). This distribution is right-skewed or positively-skewed (has a long right tail)
So, correct option is option B
Permutation is considered an ordered combination. The general formula for this is:
P(n, r) = n! (n-r)!
where:
n=
