Answer:
Yes no no
Step-by-step explanation:
2 m/s²
Step-by-step explanation:
Step 1:
Let the initial velocity be 0 m/s and the final velocity be 8 m/s and the time traveled is 4 s.
From the basic science,
Acceleration = ( Final Velocity - Initial Velocity) / Time
Step 2:
Acceleration = (8-0)/4
2 m/s²
Answer:
Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54
Step-by-step explanation:
Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and uses 582 kilowatt-hours per year.
Let's assume he buys brand B, so he already has a loss over the price of the commodity that is , loss = 647 - 569 =$78
Cost of electricity = $0.18
Now in the case of electricity,
spending on Brand A = 635
0.18 = $114.3
spending on Brand B = 582
0.18 = $104.76
Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54
Answer:
5
Step-by-step explanation:
a = 3; b = -2
a - b = 3 - (-2) = 3 + 2 = 5
Answer:
This is proportional since rearranging it would get x/y = 2, which is an example of direct proportionality.
