The distance an object falls is directly proportional to the square of the time it falls. A ball falls 144 feet in 3 seconds. How far will an object fall in 4 seconds?
Answers
Answer:
d = 256 ft.
Step-by-step explanation:
The distance an object falls is directly proportional to the square of the time it falls.
First, we name the variables.
Let d= the distance.
t= time
Write the formula for direct variation, where y varies directly with the square of x.
y=kx2
We will use d in place of y and t in place of x.
d=kt2
Substitute the given values for the variables.
d=144whent=3144=k⋅32
Solve for the constant of variation.
144916=k⋅99=k
Write the equation that relates d and t.
d=kt2
Substitute in the constant of variation.
d=16t2
Find d when t=4.
Write the equation that relates d and t.
d=16t2
Substitute the given value for t.
d=16⋅42
Simplify.
d=256
An object will fall 256 feet in 4 seconds.
The required distance fall by fall in 4 seconds is 192 feet.
Given that,
The distance an object falls is directly proportional to the square of the time it falls. A ball falls 144 feet in 3 seconds, how far will an object fall in 4 seconds is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.
here,
The rate of fall of the ball = 144 / 3
= 48 feet second
Now distance fall by the ball in 4 seconds = 48 * 4 = 192 feets.
Thus, the required distance fall by fall in 4 seconds is 192 feet.

Answers
Answer:
119.76
8 days
0.5217
93
Step-by-step explanation:
Given that:
1)
Kim's time = 135.46 seconds
Tyron's time is 15.7s faster ;
Tyron's time = 135.46 - 15.7 = 119.76
Janna takes her medicine 3 times a day. How many days will a 60 ml medicine last if 2 1/2ml is taken each time?
(2 1/2 * 3) = 7.5 mL per day
60 mL / 7.5 = 8 days
3. May bought 23 of a kilo of meat. She cooked 12 of it. How much did she cook?
Total bought = 23 of a kilo of meat
Amount cooked = 12 /23= 0.5217 kilo
4. Arjay bought 8.75 meters of cloth for ₱813.75. Find the cost price per meter.
Cost per meter :

southbound boat goes seven miles per hour How many hours will it take them to be 66 miles apart?
he
Addit
Answers
Answer:
It will take them (Matt and Chris) 0.395 hours to be 64 miles apart
It will take 5.5 hours for the boats to be 66 miles apart
Step-by-step explanation:
We are to determine the time when Matt and Chris will be 64 miles apart, that is, when the total distance traveled by both of them will be 64 miles.
Let the time be t and
Let the distance covered by Matt be S₁ and the distance covered by Chris be S₂.
For Matt,
From the question, Matt drives at a speed of 79 miles per hour
From the formula
Distance = Speed × Time
S = v × t
∴ S₁ = 79×t
S₁ = 79t
For Chris,
From the question, Chris drives at a speed of 83 miles per hour
Using the same formula,
∴ S₂ = 83 × t
S₂ = 83t
To determine when they will be 64 miles apart, that is when S₁ + S₂ = 64 miles.
Hence,
S₁ + S₂ = 79t + 83t
∴64 = 79t + 83t
64 = 162t
t = 64/162
t = 0.395 hours
Hence, it will take them 0.395 hours to be 64 miles apart.
For the boats,
To determine how many hours it will take them to be 66 miles apart, that is when the total distance traveled by the two boats will be 66 miles.
Let the time be t and
Let the distance traveled by the northbound boat be S₁ and the distance traveled by the southbound both be S₂.
From the question,
The northbound boat travels five miles per hour
From the formula
Velocity = Distance / Time
Then, Distance = Velocity × Time
That is, S = v × t
Hence, for the northbound boat,
S = S₁
v = 5 miles per hour
∴ S₁ = 5t
Also from the question,
The southbound boat goes seven miles per hour
Hence, for the southbound boat
S = S₂
v = 7 miles per hour
∴ S₂ = 7t
To determine when the boats will be 66 miles apart, that is when S₁ + S₂ = 66 miles
Then,
S₁ + S₂ = 5t + 7t
Hence,
66 = 5t + 7t
66 = 12t
t = 66/12
t = 5.5 hours
Hence, it will take 5.5 hours for the boats to be 66 miles apart.

Answer:
b. To provide an idea of what the population standard deviation might be
Step-by-step explanation:
Pilot sample can be regarded as the
small scale preliminary experiment whereby a smaller size of samples which is smaller compare to expected size is taken population of interest which gives the estimate for the population standard deviation.
The population standard mean is a parameter and it's been calculated from every entity of the population and
can be calculated using below formula
σ =√Σ (xi -μ)^2 /N
Where N= size of the population
σ= population standard mean
μ= population mean
Xi=each sample from the population
