The trapezoid's area is 126 inch².
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area, 
.
Here 
is the lower base and 
is the upper base, height is h.
Step 2:
In the given diagram,
inches and 
inches and h = 9 inches.
inch².
So the given trapezoid's area is 126 inch².
This is for any polyhedron that does not intersect itself. The Euler's formula states that the number of faces plus the number of vertices or corner points less the number of edges is always equal to 2.
Faces + Vertices - Edges = 2
A cube has 6 faces, 8 vertices, and 12 edges.
<span>Euler's formula: 6 + 8 - 12 = 2 ⇒ 14 - 12 = 2 ⇒ 2 = 2 ur welcome man </span>
Answer:
arctan(4/3) ≈ 0.9272
Step-by-step explanation:
On comparing eqⁿ to y = mx + c,
Slope of 2x + 4y = 7 is -2/4 = - 1/2
Slope of x + 2y = 5 is - 1/2
Therefore, if A is the angle b/w them,
A = arctan | (m1 + m2)/(1 - m1m2) |
A = arctan | (-½ - ½)/(1 - ¼) |
A = arctan (4/3)

Answer:
no
22.25 minutes
Step-by-step explanation:
First determine how long it will take her to read the entire book
20 pages 47 pages
-------------- = ----------------
35 minutes x minutes
Using cross products
20x = 35*47
20x=1645
Divide by 20
20x/20 = 1645/20
x =82.25 minutes
This is more than 1 hour ( 1 hour = 60 minutes)
82.25 minutes - 60 minutes = 22.25 minutes
She will need 22.25 more minutes
