In total, there are 40 marbles. 25 of those marbles are green. What I did was divide the number of green marbles by fourth, the total number of marbles. (25/40) You should come up with 0.625. Then you convert the decimal into a fraction. 5/8 is equivalent to 0.625. Thus, 5/8 of the marbles are green.
Hope this helps :)
You did the equation a little wrong. It is A^2 + B^2 = 10^2
Answer:56
Step-by-step explanation:add all the sides together
Angle 4 would also be 135. the two on the top would add to 180, making a whole circle altogether that equals 360. so, you would do 180-135 = 45. angle 5 is 45. angle 7 would also be 135 because angle 4 and 7 are vertical angles.
