Answer: 9.44 seconds
Step-by-step explanation:
A movement equation in the vertical axis is usually written as follows:
p(t) = (-g/2)*t^2 + v0*t + p0
where:
g is the gravitational acceleration, in this case is 32 ft/s^2, then -g/2 = -16ft/s^2
v0 is the initial velocity, in this case, 24 ft/s
p0 is the initial height, in this case, 1200ft
Then, when p(t) = 0ft will mean that the pebble will hit the ground, then we need to calculate:
p(t) = -16t^2+24t+1200 = 0
and find the value of t, this is a quadratic equation, then we can use the Bhaskara equation to find the two solutions, these are:
[tex]t = \frac{-24 +- \sqrt{24^2 - 4*(-16)*1200} }{2*-16} = \frac{-24 +- 278.2}{-32}[/tex]
Then the two solutions are:
t = (-24 + 278.2)/-32 = -7.94 seconds (we can discard this one, because the negative time is not really defined)
t = (-24 - 278.2)/-32 = 9.44 seconds
Then the pebble needs 9.44 seconds to hit the ground

Alex bought a new aquarium. He is in the process of setting it up. The aquarium is in the shape of a right rectangular
prism and the dimensions, in inches, are 367 x 19 x 24. During the set-up, Alex fills the aquarium with 6,039
ins of water.
What percent of the volume of the aquarium is filled with water? Round your answer to the nearest whole percent.
Enter your answer in the space provided.
Answer:
4%
Step-by-step explanation:
Formula for volume of a right rectangular prism is;
V = lwh
Where;
l is length
w is width
h is height
We are given l = 367; w = 24; h = 19
Thus;
Volume is;
V_full = 367 × 24 × 19
V_full = 167352 in³
We are told that Alex filled the aquarium with 6039 in³ of water.
Thus, percentage of the aquarium filled with water is;
(6039/167352) × 100% = 3.61%
Approximating to nearest percent gives; 4%

Answer:
The surface area of the net shown is: 88 [tex]in^2[/tex]
Step-by-step explanation:
Break up the different shapes in the net:
Let's take the big square first:
It has a side of 5in and a base of 4in.
We multiply both these values to get 20[tex]in^2[/tex]
Lets look at the small rectangular box now:
It has a side of 3in and a base of 4in.
We multiply both these values to get 12[tex]in^2[/tex]
There are two big squares so we add up their surface areas:
20[tex]in^2[/tex] + 20[tex]in^2[/tex] = 40[tex]in^2[/tex]
There are 4 small rectangular squares so we add up their surface areas:
12[tex]in^2[/tex] + 12[tex]in^2[/tex] + 12[tex]in^2[/tex] + 12[tex]in^2[/tex] = 48[tex]in^2[/tex]
Now we add up the big square and small rectangular squares values:
40[tex]in^2[/tex] + 48[tex]in^2[/tex] = 88[tex]in^2[/tex]
Therefore the answer is 88[tex]in^2[/tex]

Why is 210 divided by 30 the same as 21 tens divided by 3 tens
21 tens is equal to 210, and 3 tens is equal to 30.
Reason behind both the situations are the same are the place values of the digits.
What are the place values?According to their position in a number, each digit has a different value in mathematics, which is called place value. From the unit's starting location, these positions begin.
Ones/units, tens, hundreds, thousands, ten thousands, and so on are all ways to describe the place value of a number's digits in sequence from right to left.
Each digit in a number has a place value, which is its worth. Each digit in a number has a unique value depending on where it sits in the number. The value of a digit depends on where it falls in the number; two comparable digits in the same number may have different values.
When 210 is written in the form of place value, this will be written as 21 tens and 30 will be written as 3 tens.
Therefore, the given statement has the same values and is correct.

Train A leaves a station traveling at 28 km/hr. Two hours later train B leaves the same
station traveling in the same direction at 84 km/hr. How many hours will it take train B to
catch up to train A?
it will take 1 hour to catch up to train a but if the question means from as soon as train a leaves, it is 3 hours.
The time taken by train B to cover the distance of 56 km when the train at the station is in 1 hour.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
Train A leaves a station traveling at 28 km/hr.
Two hours later train B leaves the same station traveling in the same direction at 84 km/hr.
The distance traveled by the train A in two hours will be
[tex]\rm D_A=28 \times 2 = 56 km[/tex]
Then the distance between the trains when train B is at the station is 56 km.
Then the relative speed of the train will be
[tex]\rm V_{BA} =84 - 28 = 56 \ km/hr[/tex]
Then the time taken by train B to cover the distance of 56 km is in 1 hour.

Graph the line that contains the point (-3,1) with a slope of 2/3
Answer:
The graph of the line [tex]y=\frac{2}{3}x+3[/tex] that contains the point (-3,1) with a slope of 2/3 is attached below.
Step-by-step explanation:
We know that the slop-intercept form of the equation is
[tex]y=mx+b[/tex]
where m is the slope, and b is the y-intercept.
Given the slope = m = 2/3, and point (-3, 1)
[tex]1=\frac{2}{3}\left(-3\right)+b[/tex]
[tex]-\frac{2}{3}\cdot \:3+b=1[/tex]
[tex]-2+b=1[/tex]
[tex]b=3[/tex]
so the equation of line will be:
[tex]y=mx+b[/tex]
[tex]y=\frac{2}{3}x+3[/tex]
Also, the graph of the line [tex]y=\frac{2}{3}x+3[/tex] that contains the point (-3,1) with a slope of 2/3 is attached below.
