. A 0.660 kg ball is dropped from rest from the top of a building and falls for
5.65 seconds. How tall was the building? [Neglect friction. Assume on or near
the Earth's surface.]
Answer:
The height of the building is 156.42 m
Step-by-step explanation:
Given;
mass of the ball, m = 0.66 kg
time of fall, t = 5.65 s
initial velocity of the ball, u = 0
Apply the following kinematic equation to determine the height of the building;
h = ut + ¹/₂gt²
h = ¹/₂gt²
h = ¹/₂ x 9.8 x 5.65²
h = 156.42 m
Therefore, the height of the building is 156.42 m
The building was 156.42 metres tall
From the question we are told that
the mass of the ball, m = 0.66 kg
the time of fall, t = 5.65 s
the initial velocity of the ball, u = 0
If we use one of the equations of motions in
h = ut + ¹/₂gt², we then have
h = (0 * t) + (0.5 * 9.8 * 5.65²)
h = 4.9 * 31.923
h = 156.42 m
The height of the building is 156.42 m

In a population of 9500 subjects, 72% possess a certain characteristic. In a sample of subjects selected from this population, possess the same characteristic. How many subjects in the population and the sample, respectively, possess this characteristic
This question is Incomplete
Complete Question
In a population of 9500 subjects, 72% possess a certain characteristic. In a sample of 400 subjects selected from this population, 73% possess the same characteristic. How many subjects in the population and the sample, respectively, possess this characteristic?
Answer:
Population = 6840 subjects
Samples = 292 subjects
Step-by-step explanation:
In a population of 9500 subjects, 72% possess a certain characteristic.
The number of subjects in the population with this characteristics =
9500 × 72%
= 6840 subjects
In a sample of 400 subjects selected from this population, 73% possess the same characteristic.
The number of subjects in this sample with this characteristics is :
400 subjects × 73%
= 292 subjects
6840 subjects in the population posses this characteristic, while 288 subjects in the sample posses this characteristic
The given parameters are:
[tex]\mathbf{n = 9500}[/tex] --- population
[tex]\mathbf{x = 400}[/tex] -- sample size
[tex]\mathbf{p =72\%}[/tex] ---- the proportion
The number of subjects that posses the characteristics is simply the average of the sample or the population.
For the population, the average is calculated as:
[tex]\mathbf{\mu =np}[/tex]
So, we have:
[tex]\mathbf{\mu =9500 \times 72\%}[/tex]
[tex]\mathbf{\mu =6840}[/tex]
This means that:
6840 subjects in the population posses this characteristics
For the sample, the average is calculated as:
[tex]\mathbf{\bar x=px}[/tex]
So, we have:
[tex]\mathbf{\bar x=72\%\times 400}[/tex]
[tex]\mathbf{\bar x=288}[/tex]
This means that:
288 subjects in the sample posses this characteristics

local bowling alley charges each person $5.25 per game bowled and $3.50 to rent a pair of bowling shoes. The bowling alley also offers food
specials. Currently, bowlers can purchase a super pizza deal, which includes a large pizza and a pitcher of soda, for only $15.50.
Five friends decide to go bowling. Each friend bowls two games and rents a pair of bowling shoes. They also buy one super pizza deal to
share.
• What is the total cost (in dollars) for the five friends to rent shoes, bowl two games, and purchase a super pizza deal? Explain or show
your work.
• If the five friends split the total cost so each one pays the same amount of money, how much does each friend pay (in dollars)?
Answer:
1. $85.50
2. $17.10
Step-by-step explanation:
1. 5.25 x 10=52.5:cost for all games total.
3.50 x 5=17.5: cost for all shoes total.
15.50: cost for super pizza deal.
Add it all together.
52.5 + 17.5 +15.50= 85.5
2. 85.5 Divided by 5 = 17.1

Answer:
x = 23
DBC = 23
ABC = 157
Step-by-step explanation:
angles ABC and CBD are supplementary.
supplementary angles add up to 180.
you can make the following equation
6x + 19 + x = 180
7x + 19 = 180
7x = 180 - 19
7x = 161
x = 161/7
x = 23
substitute x into the equations
DBC = x
DBC = 23
ABC = 6x + 19
ABC = 6 * 32 + 19
ABC = 138 + 19
ABC = 157

Answer:
Okay I think these are the answers for the Static blurs in the passage the principal reads
Good morning students, teachers, and staff! The teachers have joined the school fundraiser. They will be selling books for summer reading. They have a set goal of 360 dollars.
This is 210 dollars more than the 8th graders, but only [tex]\frac{4}{5}[/tex] as much as the 7th graders. For every 60 dollars the teachers plan to raise, the 6th graders plan to raise 50 dollars
The reason why the teachers goal is $360 is because on page 12 on the graphs it says that the teachers goal is $360, now thats big brain thinking
The teachers goal is 210 dollars more than the 8th graders because 360 - 150 = 210. It is also [tex]\frac{4}{5}[/tex] of the 7th graders goal because 6th graders plan to raise 50 dollars because $60*6=360 and $50*6 is $300. 6 is the common multiple of of 50 and 60
50, 100, 150, 200, 250, 300
60, 120, 180, 240, 300, 360
Boom.
For B you can say
1. The 6th grades' goal is more than the 8th graders goal
2. The 7th grades' goal is more than the 6th and 8th
3. The 8th grades' goal is [tex]\frac{1}{2}[/tex] of the 6th grades' goal
C I think the teachers goal is 360

Show how to solve the following; answer must be with fractions and pi
theta=tan^-1(-6/6)
I can get the decimal form from calculator, but I require the fractional answer and I need to know how it even gets obtained. How do we know what inverse tan of -6/6 will = to?
Answer:
3pi/4 and -pi/4
Step-by-step explanation:
We can simplify -6/6 to -1.
Therefore, this function can be simplified to arctan(-1).
Recall that the meaning of arctan is to find a value that will get the value inside the parenthesis when taken the tangent of it. In other words, tan(x) = -1.
Recall that tan(x) = sin(x)/cos(x). Now recall that sin(pi/4) and cos(pi/4) are both sqrt(2)/2, meaning that tan(pi/4) is 1. To make it -1, we can either make sin(x) -1 while keeping cos(x) 1, or the other way around.
If x is -pi/4, cos(x) will still be 1, but sin(x) will be -1, so tan(-pi/4) will be -1.
If x is 3pi/4, cos(x) will be -1, but sin(x) will still be 1, so tan(3pi/4) will be -1.
Side note: there are still infinite more answers. You can attain them by adding or subtracting 2pi as many times as you want from 3pi/4 or -pi/4 and still get an arctan of -1.

THANK YOU
Answer:
x = 45°
Step-by-step explanation:
The total measurement is 360° (the measurement of a circle).
Set the equation. Set all measurements equal to 360:
228 + (x + 29) + (x + 13) = 360
Combine like terms:
228 + 29 + 13 + 2x = 360
2x + 270 = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to other. Do the opposite of PEMDAS. First, subtract 270 from both sides:
2x + 270 (-270) = 360 (-270)
2x = 360 - 270
2x = 90
Next, divide 2 from both sides of the equation:
(2x)/2 = (90)/2
x = 90/2
x = 45
x = 45° is your answer.

B. Paul
Answer:
A. Eva
Step-by-step explanation:
Given that
The entire school, 250 students, went to the soap box derby.2 vans went to soap box derby and each van held 6 students.
To find the total number of students from the Math Club who went to the soap box derby, we need to add the number of students in each van, the number of times equal to the number of vans.
i.e. by adding 6 (i.e. number of students in each van) 2 (number of vans )number of times, we can get the number of students from Math Club who went to the soap box derby.
Number of Math Club students who went to the soap box derby = 6 + 6 = 12
OR
Simply, multiply number of students in each van with the number of vans .
6 [tex]\times[/tex] 2 = 12
Therefore, Eva is correct about the calculations.
