At the end of three days, % of the original amount of liquid remains in Kyle's container .
<u>Step-by-step explanation:</u>
Here we have , Every day 10% of the liquid present in the morning in Kyle's open container will evaporate. At the end of three days, We need to find what percent of the original amount of liquid remains in Kyle's container . Let's find out:
Let's suppose initially we have 100% of liquid present so ,
<u>At day 1:</u>
10% of the liquid present(100%) in the morning in Kyle's open container will evaporate , So left is :
⇒
⇒
⇒ %
<u>At day 2:</u>
10% of the liquid present(90%) in the morning in Kyle's open container will evaporate , So left is :
⇒
⇒
⇒ %
<u>At day 3:</u>
10% of the liquid present(81%) in the morning in Kyle's open container will evaporate , So left is :
⇒
⇒
⇒ %
Therefore , At the end of three days, % of the original amount of liquid remains in Kyle's container .
Correct question :
The average speed that a tsunami (a large tidal wave) travels is represented
by the function where s is the speed (in miles per hour) that the tsunami is traveling and d is the average depth (in feet) of the wave.
a. Find the inverse of the function.
b. Find the average depth of the tsunami when the recorded speed of the wave is 250 miles per hour.
Answer:
a)
b) 312.5 ft
Step-by-step explanation:
Given:
Average speeds,
a) To find the inverse of the function.
s² = 200d
200d = s²
Therefore, inverse of the function =
b) average depth when speed is 250 miles per hour.
Average depth = d
Therefore, let's use the formula :
d = 312.5 feet
The average depth when speed is 250 miles per hour is 312.5 ft
Answer:
a
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
let x be the other leg to be found, then
155² = 124² + x²
24025 = 15376 + x² ( subtract 15376 from both sides )
8649 = x² ( take the square root of both sides )
= x
Hence x = 93 cm ← length of other leg → a
