Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
Answer:
z=62 degrees
y=117 degrees
Step-by-step explanation:
z is just supplement of 118 degree angle. So z is just 180-118=62.
The sum of all angles in the four sided shape is ((number of sides)-2)180.
(4-2)180=360.
We know three angles already.
360-62-97-84=117
Thus, y is 117 degrees.
Answer:
-The measure of :
-The measure of (if needed):
Step-by-step explanation:
-Set the measure of on one side and set the measure of on the other side and it will be written as:
-Then, solve for :
-After you have found the value of , plug in both the measure of and in order to get the actual angle measurement of and :
Finding the measure of :
Finding the measure of :
-Notice: That reason why both and have the same measurements, its because they are Alternate Exterior Angles, based on the diagram shown.
