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
Answer:
2062.50
Step-by-step explanation:
Interest = (Principle x rate x time)/100
Amount = Principle + interest
Principle = 750
Rate = 7%
Time = 25 years
(750 x 7 x 25)/100
= 131250/100
=1312.50
Principle = 750
Interest = 1312.50
Amount = 750 + 1312.50
Amount = 2062.50
Step-by-step explanation:
Since we have given that
By using logarithmic on both sides we get,
(∵ 
)
Now, differentiating on both sides ,we get,
A) get rid of the fraction by finding the common denominator, 4. multiplying by 4 on both sides, I usually have it turned into a fraction, 4/1. The 2x=3/4, is now 8x=12/4 will be set as 8x=3. Divide 8, x=3/8.
B) The common denominator is 15. Multiply on both sides, -2/5 times 15/1 is -30/5 which becomes -6. And m/3 times 15/1 is 15m/3, 5m. divide the 5 and your answer is m=-5/6
Answer:
C) Ø not possible
Step-by-step explanation:
Solve |x| + 7 < 4.
subtract 7 first
|x| < 4 - 7
|x| < -3
this is impossible, a positive number cannot be less than a negative number
