x²+2x=0

x(x+2)=0

katen-ka-za [31]

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 $\times$ 0.18 = $114.3

spending on Brand B = 582 $\times$ 0.18 = $104.76

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

What is 78,045 rounded to the nearest thousand?

Makovka662 [10]

79, 000
Tip: focus on the number/place you need to round from ( in this case 8) if the number is 4 or below it will stay the same, but if the number is 5 or above it will change by 1 number (in this case it will change from 78, 045 to 79, 000)
