Answer:
460 mi²
Step-by-step explanation:
The surface area consists of 3 rectangles of the sides, and the two base triangles.
The front rectangle has dimensions of 10x11, so it's area is 110 in²
The left side rectangle has dimensions of 10x11, so it's area is 110 in²
The right side rectangle has dimensions of 12x11, so it's area is 132 in²
The top and bottom triangles have a base of 12 and a height of 8, so their area is
A = (1/2)(12)(8) = 108/2, but there are 2 of them, so their combined area is (108/2)(2) = 108 in²
The total surface area is 110 + 110 + 132 + 108 = 460 mi²
Let the constant be k.
For an inverse squared proportion the formula is y = k/x^2
Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48
Hope this helps. :)
Answer:
75.36cm
Step-by-step explanation:
We use the pithagorean theorem: height^2 = 152^2 - 132^2 = 5680;
height = 
Answer:
8/9
Step-by-step explanation:
Multiply the given equation by 2/(9a).
4a(2/(9a)) = 9b(2/(9a))
8/9 = 2b/a
Answer:
x = 148
Step-by-step explanation:
The angles shown are vertical angles.
Vertical angles are congruent ( equal to each other )
Because vertical angles are equal to each other x = 148
