Answer
Find out how many seconds faster has Alexandria's time then Adele's time .
To proof
Let us assume that seconds faster has Alexandria's time then Adele's time be x.
As given in the question
Adele Swam the length of the pool in 32.56 seconds. Alexandria swam the length of the pool in 29.4 seconds.
Than the equation becomes
x = 32.56 - 29.4
x = 3.16 seconds
Therefore the 3.16 seconds faster has Alexandria's time then Adele's time .
Hence proved
9514 1404 393
Answer:
- perimeter ratio: 4 : 3
- area ratio: 16 : 9
Step-by-step explanation:
The ratio of perimeters is the ratio of corresponding sides.
first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters
The ratio of areas is the square of the ratio of linear dimensions.
first : second = 4² : 3² = 16 : 9 . . . ratio of areas
Answer:
9 years
Step-by-step explanation:
You want to find t such that y=10.
10 = 7.67(1.03)^t
10/7.67 = 1.03^t . . . . . divide by 7.67
log(10/7.67) = t·log(1.03) . . . . . . take logs
log(10/7.67)/log(1.03) = t ≈ 8.9743 . . . . . years
After about 9 years, the employee will be earning $10 per hour.
