What am i supposed to do??
miskamm [114]
Exterior angle theorem
16x - 7 = 8x + 2 + 10x - 19    ===>  16x -7 = 18x - 17
16x - 16x - 7 = 18x - 16x - 17 ===> -7 = 2x - 17
-7 + 17 = 2x - 17 + 17             ===> 10 = 2x ======> 5 = x
Plug x in to each equation.
Angle P: 8(5) + 2 = 42 deg, Angle Q: 10(5) - 19 = 31
The sum of interior angles = 180. 180 - 42 -31 = 107 deg (angle of PRQ)
To check that line other angle : 16(5) -7 = 73 deg + 107 = 180 deg

Easy question:
Delvig [45]

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.

woman works out by running and swimming. When she runs, she burns 7 calories per minute. When she swims, she burns 8 calories pe
RSB [31]
An inequality to model this would be

7x + 8y ≥ 336.

We multiply the number of minutes running, x, by the number of calories burned each minute by running, 7.  We multiply the number of minutes swimming, y, by the number of calories burned each minute by swimming, 8.  Adding these together, it needs to be greater than or equal to 336, since she wants to burn at least that many calories.
