40 170,000,000,000
----- = --------------------------
100 x
Multiply diagonally to solve
So you get 40x = 17,000,000,000,000
Then divide each side by 40 to get x alone
So the answer is 42,500,000,000,000
Answer:
61
Step-by-step explanation:
since it is a right angle, you subtract 90 by 29 to get 61
The total lateral surface area
This is the area of the sides of the figure. In this case it will be the sum of the three rectangles.
(13) * (14) + (13) * (14) + (14) * (10) = 504yd ^ 2
the total surface area.
This is the surface area of the whole figure. In this case there are three rectangles and two triangles.
(13) * (14) + (13) * (14) + (14) * (10) + (1/2) * (10) * (12) + (1/2) * (10) * (12 ) = 624 yd ^ 2
the answer is
total lateral surface area: 504yd ^ 2
total surface area: 624 yd ^ 2
Answer:
65
Step-by-step explanation:
the sum of interior angles in a triangle equal to 180°
so 45+70=115
180-115=65
A n =?
If the arithmetic sequence is:-20, - 16, - 12 , - 8 ...
a 1 = -20, d = 4 ( a 2 = -20 + 4 = -16, a 3 = -16+4 = -12,...)
And the formula for nth term is:
a n = a 1 + d (n -1)
a n = -20 + 4( n -1) (n=1.2.3...)
