Total number of gumballs in the gumball machine =
23 + 52 + 34 + 61 + 30 = 200
% of the gumballs being red = 52/200 * 100
= 52/2
<u> = 26 %</u>
Hence, <u>26% of the gumballs</u> are red in the gumball machine
Setting goals helps trigger new behaviors, helps guides your focus and helps you sustain that momentum in life. Goals also help align your focus and promote a sense of self-mastery.

The given angles sum to less than 90°, so the remaining angle must be more than 90°. (The total of all angles is 180°.) Triangle ABC has an angle greater than 90°, so is obtuse. Since the triangles are similar, their corresponding angles are congruent. Hence ...
.. D. Triangle XYZ is obtuse.
