Find the interest earned in 1 year and divide it by 12 (number of months per year)
simple interest=principal times rate times time
so we have 1250 principal (amount invested)
rate is 5% or 0.05
time is 1 year
in 1 year, he earns 1250 times 0.05 times 1 or $62.5 per year
divide by 12
62.5/12=5.2083333333333333333333333333333
earns about $5.21 per month in interest
3/5 mile in 1/20 hours =3 minutes . so in 1 minute he skates 1/5 of a mile . in 60 minutes he skates 12 miles . speed is 12mph
Since 12.3 is less than 21 it will be a negative number. so just subtract 12.3 from 21 and put a negative symbol in front of the answer.
Answer:
x=8.4
Step-by-step explanation:
use tangent to solve the equation which is opposite/adjacent and set up the proportion

the cross multiply to get x=tan(35)×12 then multiply that to get x=8.4
Answer:
If you're solving for F then F=1. If you're solving for x then there's no solution
