Answer:
It will take nine years and four months for the refrigerator to pay for itself.
Step-by-step explanation:
The new refrigerator which costs $1200, saves the family 22% annually in energy cost.
Since the old refrigerator costs $580 to run, we want to determine how many years it will take for 22% of $580 per year to make $1200.
22% of $580
= 580 × 0.22
= 127.6
That is, it saved then $127.6 per year.
Now,
$1200/127.6
≈ 9.4
Which means, it will take 9 years and 4 months for the refrigerator to pay for itself.
40 bikes. 120 times 40 equals 4800 divided by 2 because they pay for half the bike will be 2400
Answer:
the area of the circle: 25π
Step-by-step explanation:
45/4 π = 11.25π
9/10π = 0.9π
11.25π / 0.9π = x / 2π .... 360° = 2π
x = (11.25π x 2π) / 0.9π = 25π
