Answer:
15/49
Step-by-step explanation:
5/7 (3/14 + 3/14)
first combine like terms
3/14 + 3/14 = 6/14
then simplify by 2
6/14 to 3/7
now that both the term inside and outside have the same denominator, multiply
5/7 x 3/7 = 15/49
The answer would be 9 you would add the 13 and 7 then have 20-5t=-25 then subtract 20 from 25 then you would have -5=-45 which is 9
My best guess would be 720.
My work: 30 x 12 = 360
360 x 2 = 720
Hope this helps! If its not right please inform me on what I did wrong!
For this case we have that by definition of trigonometric relations of rectangular triangles, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. So:
Where h is the hypotenuse.
We cleared h:
We rationalize:

Option A
Answer: 84.14
Step-by-step explanation:
Area of the rectangle is L*W=B*H
14*5=70
To find the area of the half circle we must use the formula pi r^2/2
r=radius
and the radius is 6 because we add 4 and 4 and need to get to 14
because the line below it is 14 and it is a rectangle so the lengths are the same.
Diameter=6
So radius =3
pi (3)^2/2=
9/2 pi + 70=
84.14
