Answer: x = 34º, y = 146º, z = 146º
Step-by-step explanation:
Adding the angles inside a triangle gives you 180º. So
85 + 61 + x = 180
146 + x = 180
x = 34º
x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.
y and z are equal (vertical angles), so z = 146º.

Step-by-step explanation:
The question implies a constant rate or distribution of calories. Therefore, we can set up the following proportion:
Answer:
3 hours and 45 minutes
Step-by-step explanation:
let's assume the tank has a volume of x liters.
let's assume the speed of filling it is x/6 liters per hour for A and x/10 liters per hour for B.
the formula to calculate the time is:
time = volume / speed
If the pumps work together, the total speed is x/6 + x/10, which is 16/60 x
So the time this takes is:
time = x / (16/60 x) = 60/16 hours = 3.75 hours = 3 hours and 45 minutes.
