Answer:
4.1 billion
Step-by-step explanation:
1 ft = 30.48 cm
1 in = 2.54 cm
The volume of rain that fell on the roof is given by ...
V = LWH
V = (175 ft × 30.48 cm/ft)(45 ft × 30.48 cm/ft)(11 in × 2.54 cm/in)
= 175×45×11×30.48²×2.54 cm³ = 204,412,236.336 cm³
At 20 drops per cm³, this will be ...
20×204,412,236.336 ≈ 4,088,244,727 . . . . raindrops
About 4.1 billion raindrops fell on your roof.
Move the decimal place to the right if the exponent is positive, and left is the exponent is negative. Add additional zeros if needed.
Answer:
1. $2,950.62
2. $93.75
Step-by-step explanation:
Ann took out a loan of = $12,000
At an interest rate of = 5.65%
Time = 4 years
Formula of compound interest = 
= 
= 
= 12,000 × 1.24588514
Interest = Amount - principal amount
= $14,950.62 - 12,000
= $2,950.62
Amount that Dan borrowed = $1,250
rate of interest = 5%
Time = 18 months or 1.5 years
Formula of simple interest = P(1+rt)
= 1250(1+(0.05 × 1.5))
= 1250(1+0.075)
= 1250 × 1.075
= 1343.75
Interest = Amount - principal
I = 1343.75 - 1250
= $93.75
