A tractor tire makes one complete rotation every 14.3 seconds.
How long does it take the tire to complete 4.25 rotations?
Answer:
60.775
Step-by-step explanation:
If one rotation is 14.3, then you will have 14.3 x 4. Then divide 14.3 by 4 (25 is 1/4 of 100) and the answer is 3.575. So 14.3*4= 57.2 + 3.575 = 60.775
the answer is 60.775.

5. Show that 12 is not a square number. Use a diagram, mathematical symbols
and then a word sentence.
Answer:
if y=x^2 the x and y chart would be as follows
x y
1 1
2 4
3 9
x 12
4 16
5 25
This shows that the x which would produce twelve is between three and 4 and thus not a perfect square
9<12<15 thus 3<x<4
12 is not a perfect square because the square of 3 is 9 and the square of 4 is 16, and since 12 lies between 3 and 4, we know that the number that would be squared to produce twelve must be a decimal between 3 and 4.
Step-by-step explanation:
A perfect square is a number that can be produced from squaring a counting number (...-3,-2,-1,0,1,2,3...)
This means that determining a perfect square comes down to knowing the squares of 1-10 so that you can create a table and determine where the number lies or between what numbers it would occur. If it is a perfect square it will already be on the table with little to no analysis necessary.

Un grupo de estudiantes tiene como proyecto final determinar el grado de aceptación de las amas de casa de cierto sector de la ciudad hacia un nuevo detergente. De los resultados obtenidos se pudo establecer que aproximadamente 95% de las amas de casa prefieren un detergente en presentación de 500 gramos, contra el mismo producto, pero en una presentación de 1500 gramos. Se lleva a cabo un sondeo sobre la predilección del tipo de presentación del detergente entre 20 amas de casa seleccionadas al azar y donde las respuestas dadas son independientes. Si los estudiantes están interesados en calcular la probabilidad de que exactamente 5 de las amas de casa prefieran la presentación de 1500 gramos, el valor que obtienen es
Usando la distribución binomial, se encuentra que hay una probabilidad de 0.0022 = 0.22% que exactamente 5 de las amas de casa prefieran la presentación de 1500 gramos.
Para cada estudiante, solo hay dos resultados posibles. O prefieren la presentación de 500 gramos, o prefieren la de 1500 gramos. La decisión de cada estudiante es independiente de otros estudiantes, o que implica que se usa la distribuición binomial.

A total of 511 tickets were sold for the school play. They were either adult tickets or student tickets. There were more student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
less than 256
Step-by-step explanation:

What are the next three terms of the geometric sequence 32, -16, 8, …?
Hello there!
A Geometric sequence is a sequence where we use multiplication or division to get to the next term.
Here, we use division.
32, -16..
What did we do to get from 32 to -16?
We divided 32 by -2, didn't we?
Now, to get from -16 to the next term, what we must do is divide by -2 again.
The answer is 8. Why? Why not -8? Because when we multiply or divide a negative number by a negative number, we get a positive number.
32, -16, 8,
We do the same thing with the next term:
32, -16, 8, -4
Divide -4 by -2:
32, -16, 8, -4, 2
And again divide by -2:
32, -16, 8, -4, 2, -1.
Hope this helps!

For the function, find the point(s) on the graph at which the tangent line has slope 2.
y=-0.025x^2 +4x
If y = -0.025x^2 + 4x, then
y' = -0.05x + 4
Set y' = 2:
2 = -0.05x + 4
-2 = -0.05x
40 = x
Go back to y to find the point:
y = -0.025(40)^2 + 4(40) = 120
So the point (40, 120) on y = -0.025x^2 + 4x will have tangent line with a slope of 2.

Victor wants to learn to snowboard. He went to Snowy Ridge Mountain and rented a snowboard for $35, then took 5 hours of group snowboarding lessons. Victor paid $175 in all.
Which equation can you use to find how much Snowy Ridge charges, x, for each hour of group snowboarding lessons?
How much does Snowy Ridge charge for each hour of group snowboarding lessons?
Snowy Ridge charges $28 for each hour of group snowboarding lessons.
Let x represent how much Snowy Ridge charges for each hour of group snowboarding lessons.
Since he rented a snowboard for $35, then took 5 hours of group snowboarding lessons. Victor paid $175 in all, hence:
175 = 5x + 35
5x = 140
x = $28 per hour
Therefore Snowy Ridge charges $28 for each hour of group snowboarding lessons.

Given: ΔABC, CM⊥AB, BC = 5, AB = 7, CA = 4√2
Find: CM
Step-by-step explanation:
first finding the area of the triangle by Heron's formula.
s=(a+b+c)/2, a=BC=5 unit, b=AC= 4√2unit, c=AB=7unit.
s=(5+4√2+7)/2 = (12+4√2)/2 =2( 6+2√2 )/2 = 6+2√2 unit .
Now, the Heron's formula : √s(s-a)(s-b)(s-c)
> √ (6+2√2)[(6+2√2)-5][(6+2√2)-4√2][(6+2√2)-7]
we have use √2's value ; 1.414 to simplify.
please simplify it with the help of calculator or doin it in a copy, because it is very difficult to share the full calculation. AFTER CALCULATION,
> √196.0000 > 14(units)².
Now, we know that the area of triangle is 14(units)². and another formula of finding the area of triangle is ½(base)(height). let the height be h.
Area = ½(base)(height)
=>14= ½(7)h. (after cross multiplication)
=>(14×2)/7=h. (after cancellation)
=>2×2=h.
=> 4units = h.
Therefore, CM that is the height is 4units.
I have every time written units because the unit is not given or you have not posted if given in the question you will write that unit only like cm or m anything like that.

A point lies to the left of the y-axis
and below the x-axis. What can you conclude about the coordinates
of the point
The point lie in quadrant 3 and both x and y coordinates of the point will be negative.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
It is given that point lies to the left of the y-axis and below the x-axis
For an example of a point in quadrant 3 and left of the y axis and below the x axis would be (-3,-3).
Therefore, the values of tangent and cotangent will be positive, while the values of sin, cosine, cosecant, and secant will be negative if trigonometric values of triangles are used in quadrant 3.
The point lie in quadrant 3 and both x and y coordinates of the point will be negative.
