$400
Answers
Answer:
40$,160$ & 60
Step-by-step explanation:
First,find the equation using y-y1/ y1-y2=x-x1=x1-x2
y-0/0-20=x-0/0-3
y=20x/3
Now put the values of x& y in the equation, for the 1st one,
y=20×6/3
=40
2nd one.y=20×24/3
=160
3rd one,
400=20x/3
X=400×3/20
=60
The values at different number of tickets and the tickets that can be bought at $400 has been determined.
What is Direct Variation?When a variable varies directly with the other variable, i.e. on increasing one variable the other variable also increases, this relation is called Direct Variation.
Let x represent the number of tickets sold
Let y represent the amount of money earned from ticket sales.
y ∝ x
y = kx
k is the proportionality constant.
The value in the table will be used to determine the value of k,
For 3 tickets, the ticket amount is $20
20 = k * 3
k = 20/3
The relation is given by
y = (20/3) x
For 6 tickets, the value will be,
y = (20/3 ) *6 = $40
For 24 tickets the value will be,
y = (20/3) * 24 = $160
For $400, how many tickets can be bought,
400 = (20/3) * x
400*3 /20 = x
60 tickets can be bought for $400

work out the circumferrence of this circle 14cm diameter give your answer in terms of pi and state its units
Answers
Answer:
Step-by-step explanation:
The circumference of a circle is given by the formula:
C = πd
where d is the diameter of the circle. In this case, the diameter is given as 14 cm, so we can substitute that into the formula:
C = π(14 cm)
Multiplying, we get:
C = 14π cm
So the circumference of the circle is 14π cm. The units are centimeters, since circumference is a length measurement.

“Hamilton,” the big winner of the 2015-16 Broadway season, has done more for the promotion of theater in this generation than any other because of its multicultural casting, parallel political themes, and contemporary rap music in its score.
a.This is an explicit thesis because it lists examples.
b.This is an explicit thesis because it directly tells us what we are about to read and gives an assertion about it.
c.This is an implicit thesis because the reader can infer that the author loved the play and is promoting it.
Answers
The statement or theory put forward by the writer is both clear and direct with supporting text, which signifies an explicit thesis. Hence, option B is correct .
Explict thesis are lucid, they give a direct statement which establishes the topic or theory to be discussed or debated while implicit thesis usually have no direct defining statement and are mostly inferred from the text. Also, the exercept supports its theory with proofs or assertions which is also a major characteristic of explicit thesis.Therefore, the thesis stated is explicit as directly establishes the topic and supports it with assertions.

Find the distance traveled in 25 seconds by an object traveling at a velocity of v(t) = 20 + 5cos(t) feet per second
Answers
Answer:
499.338 feet
Step-by-step explanation:
You want to know the distance traveled by an object in 25 seconds when its velocity is described by 20+5cos(t) feet per second.
DistanceThe distance an object travels is the integral of its velocity. For the given velocity and time period, the distance is ...
\(\displaystyle d=\int_0^{25}{v(t)}\,dt=\int_0^{25}{(20+5\cos(t))}\,dt=(20t+5\sin(t))|_0^{25}\\\\d=500+5\sin(25)\approx\boxed{499.338\quad\text{feet}}\)
The distance traveled in 25 seconds is 499.33 feet.
It is required to find the distance traveled in 25 seconds.
What is distance?The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Given:
We have to find the distance , we will integrate v(t) from 0 to 25 second.
Consider an object traveling at constant velocity v = k. Then, each second, it travels k feet, so after t seconds, the distance traveled is k*t.
Now, suppose its speed increases by 1 feet/sec . So, estimate for distance traveled after t seconds is
1 + 2 + 3 + 4 + ... + t = t(t+1)/2, or approximately 1/2 t^2.
According to given question we have
Given a velocity function v, the distance s is figured by taking the integral. In this case,
v = 20 + 5 cos(t)
s = 20t + 5 sin(t) from 0 to 25
= s(45)-s(0)
s(0) = 0
so, the distance is
s(25) = 20*25 + 5sin(25)
= 500 -0.661
=499.33 feet.
Therefore, the distance traveled in 25 seconds is 499.33 feet.

To check if what you have done is correct you add all the values you got after subtracting, if you get 0 your answer is correct. Then you square each of those answers you get after you subtract.

Determine the measurement of EF.
EF = 3.47
EF = 3.16
EF = 1.39
EF = 1.1
Answers
the answer is "EF = 3.16". According to condition of Similar triangles.
How to solve these problem?
To solve this problem, we will use the property of similar triangles, which states that corresponding angles of similar triangles are equal, and their corresponding sides are proportional.
First, we need to find the ratio of the sides of the two triangles. We can do this by dividing the length of one side of triangle ABC by the corresponding side of triangle DEF. Let x be the length of EF, then:
AB/DE = BC/EF = CA/DF
Substituting the given values, we get:
11/4.4 = 7.9/x = 7.6/(DE + x)
Solving for x, we get:
x = 3.16
Therefore, EF = 3.16.
Hence, the answer is "EF = 3.16".
Note that we can also check our answer by verifying that the corresponding sides of the two triangles are proportional using the ratios we found:
AB/DE = 11/4.4 = 2.5
BC/EF = 7.9/3.16 = 2.5
CA/DF = 7.6/(4.4+3.16) = 2.5
Since the ratios are all equal, we can conclude that the triangles are similar.

2 barrels (located at 1) are 2 units from the fulcrum (triangle) → 2(2) = 4
1 barrel (located at 0) is 3 units from the fulcrum (triangle) → 1(3) = 3
Total = 8
Right side:
1 barrel (located at 6) is 3 units from the fulcrum (triangle) → 1(3) = 3
1 barrel (located at 8) is 5 units from the fulcrum (triangle) → 1(5) = 5
