Answer:
Step-by-step explanation:
Let the angle between 
and 150° be = b°
[ Forming a linear pair of angles]
Solving for 
by subtracting both sides by 150.
∴ 
[Angle lying on a straight line add up to 180]
Plugging in
Solving for 
by
subtracting both sides by 80.
then dividing both sides by 2.
Equation for company a: y=20x+8
Equation for company b: y=24x+4
Company A would be cheaper for 5 loads of laundry, because it is $108 dollars opposed to $124 which is what company b would charge for 5 loads.
$32 dollars is saved by using the services of company A instead of company B to clean 9 loads of laundry.
Answer:
C, B
Step-by-step explanation:
x y
A 34 408
B 40 480
C 46 588
A= $12/hour
B= $12/hour
C= $12.78/hour
The difference between A and B is 72. The difference between B and C is 108.
The formula that is useful for solving both of these problems is ...
9. Given v₁=15, a=9.8, d=10, find v₂.
... (v₂)² = 15² + 2·9.8·10
... v₂ = √421 ≈ 20.5 . . . . m/s
10. Given d=12 m when a=-9.8 m/s² and v₂=0, find d when a=0.17·(-9.8 m/s²).
The formula tells us that d=(v₁)²/(2a), which is to say that the distance is inversely proportional to the acceleration. If acceleration is 0.17 times that on earth, distance will be 1/0.17 ≈ 5.88 times that on earth.
(12 m)/0.17 ≈ 70.6 m
I don't think it is. I may be wrong though
