Answer and Explanation:
Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles.
Answer: 2.44 inches
Step-by-step explanation:
Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.
The number of inches that are between the two cities will be represented by x. Therefore,
1/x = 45/110
Cross multiply
45x = 110
x = 110/45
x = 2.44 inches
The Distance between the two cities on the map is 2.44 inches

Step-by-step explanation:
A prism is named by the shape of its bases. That makes this an octagonal prism
The shape of the bases are octagons.
The vertices are all the letters
The lateral edges are all the vertical lines connected by the vertices. RQ, WN, VM, are all examples.
The rectangles making up the sides are called lateral faces.
The altitudes are the same as the lateral edges. They all represent the height of the prism.

Define x :
-----------------------------------------------
Let the width be x
Width = x
Length = 4x + 7
-----------------------------------------------
Formula :
-----------------------------------------------
Perimeter = 2 (Length + Width)
Perimeter = 74
2(4x + 7 + x) = 74 // sub length and width into the equation
2(5x + 7) = 74 // combine like terms
10x + 14 = 74 // Apply distributive property
10x = 60 // Take away 14 from both sides
x = 6 // Divide by 10 on both sides
-----------------------------------------------
Find Length and Width :
-----------------------------------------------
Width = x = 6mm
Length = 4x + 7 = 4(6) + 7 = 31mm
----------------------------------------------------------------------------------------------
Answer: The length is 31mm and its width 6mm.

Answer:
17.6
Step-by-step explanation:
Formula= sumfx÷sumf
sumfx= 63×0+34×0+27×1+13×2=53
sumfx=0+0+1+2=3
53÷3= 17.6
final answer =17.6
