Answer:
6.79
Step-by-step explanation:
-Let X denote the total amount of the job.
-The job has to be done in 5 hrs, therefore the portion done every hour is:

Therefore, the rate of Bill and Ted working jointly must equal the rate calculated above:


Hence, Bill working alone should complete the house in 6.79 hrs
100-0.0124=99.9876
10%=1/10
1/10P=P(0.999876)^t
divide both sides by P
1/10=0.999876^t
take ln of both sides
ln(1/10)=t (ln(0.999876))
divide both sides by (ln(0.999876))
ln(1/10)/(ln(0.999876))=t

17 inches
15^2 + 8^2 = 289
square root of 289 = 17 inches
Log(4k - 5) = log(2k - 1)
log(4k) - log(5) = log(2k) - log(1)
0.6020599913k - 0.6989700043 = 0.3010299957k - 0
0.6020599913k - 0.6989700043 = 0.3010299957k
<u>-0.6020599913k -0.6020599913k</u>
<u>-0.6989700043</u> = <u>-0.3010299957k</u>
-0.3010299957 -0.3010299957

Answer:
2x - 8
Step-by-step explanation:
Product of two and a number x
⇒ 2 multiply by x
⇒ 2x
Eight less than 2x
⇒ Take away 8 from 2x
⇒ 2x - 8
