The answer is:
The correct option is:
C. 18 inches.
Why?To calculate the volume of a cylinder we need to use the formula:
[tex]Volume=\pi *radius^{2}*height[/tex]
We are given a cylinder that has a volume of 288 π cubic inches and we know that its radius is equal to 4 inches, so, to calculate the height of the cylinder, we need to isolate it from the equation of volume, so, isolating we have:
[tex]Volume=\pi radius^{2} height[/tex]
[tex]\frac{Volume}{\pi radius^{2} }=height[/tex]
Now, substituting the given information, we have:
[tex]height=\frac{288\pi in^{3}}{\pi (4in)^{2} }=\frac{288\pi in^{3}}{16\pi in^{2} }=18in[/tex]
Hence, we have that the correct answer is:
C. 18 inches.
Have a nice day!
Answer:
The correct answer is option c 18 inches
Step-by-step explanation:
Points to remember
Volume of cylinder = πr²h
Where r - Radius of cylinder and
h - Height of cylinder
To find the height of cylinder
Here volume = 288π cubic inches and radius = 4 inches
Volume = πr²h
288π = π* 4² * h
288 = 16h
h = 288/16 = 18 inches
Therefore height of cylinder = 18 inches
The correct answer is option c 18 inches
For what values of y does 125=(1/25)^y-1
[tex]125 = \frac{1}{125} {}^{y - 1} \\ 125 = ( {5}^{ - 2} ) {}^{y - 1} \\ \\ {5}^{3} = {5}^{2 - 2y} \\ 3 = 2 - 2y \\ - 0.5 = y[/tex]
Answer:
The answer is [tex]y=-0.5[/tex]
Step-by-step explanation:
In order to determine the "y" value, we have to change the way of we see the equation.
In these cases, when the variable is in the exponent and it is possible to make two exponents in each side of the equation, we have to equal bases and then we have to make other equation between the exponents of both sides.
So,
[tex]125=(\frac{1}{25})^y^-^1\\(5)^3=(5^-^2)^y^-^1\\(5)^3=(5)^-^2^*^y^+^2\\[/tex]
Then, we have to make an equation between the exponents of both sides:
[tex]3=-2*y+2\\2*y=2-3\\2*y=-1\\y=\frac{-1}{2}=-0.5\\ y=-0.5[/tex]
Finally, the value of "y" is -0.5
If you repeat the perpendicular line segment construction twice using paper folding, you can construct:
A.the midpoint of a line segment.
B.an angle congruent to a given angle.
C.a parallel to a line through a point not on the line.
D.an angle bisector.
Final answer:
By repeating the perpendicular line segment construction twice using paper folding, one can effectively find the midpoint of a line segment, demonstrating the application of geometric principles and theorems related to perpendicular constructions.
Explanation:
If you repeat the perpendicular line segment construction twice using paper folding, you can construct the midpoint of a line segment. This is based on the principle that constructing perpendiculars at the ends of a given line segment and then erecting a third perpendicular midway between them will intercept the line segment at its midpoint. This is affirmed by the theorems that explain the geometrical properties and relationships of constructing perpendicular lines and their midpoints.
To elucidate, let's take a line segment AB of a certain length, and fold the paper to construct a perpendicular line at point A. Next, repeat the same action at point B. Now, fold the paper to find the midpoint of AB, and erect a perpendicular line at this midpoint. This results in the third perpendicular intersecting AB exactly at its midpoint, demonstrating that this method is effective for finding the midpoint of a line segment, thereby validating option A.
You can construct: The midpoint of a line segment.
The correct option is (A).
Paper folding constructions can be used to create geometric shapes and lines based on certain properties. Let's break down each of the given options and see if they can be achieved by repeating the perpendicular line segment construction twice:
A. The midpoint of a line segment: Yes, this can be achieved. Folding a line segment in half will give you its midpoint. By repeating the perpendicular line segment construction twice, you fold the line segment once to find a point equidistant from both endpoints (which is the midpoint), and folding it again should confirm that the resulting point is indeed the midpoint.
B. An angle congruent to a given angle: No, this cannot be achieved. The perpendicular line segment construction does not involve creating or manipulating angles, so it cannot be used to construct an angle congruent to a given angle.
C. A parallel to a line through a point not on the line: No, this cannot be achieved. The perpendicular line segment construction does not involve creating parallel lines.
D. An angle bisector: No, this cannot be achieved. Again, the perpendicular line segment construction does not involve manipulating angles, so it cannot be used to construct an angle bisector.
Therefore, the correct option is:
A. The midpoint of a line segment.
| x-3 | < x-3
can someone give a step by step process on how to do this?
Answer:
There are no solutions to the inequality.
Step-by-step explanation:
|x - 3| < x – 3
1. Separate the inequality into two separate ones.
(1) x – 3 < x – 3
(2) x – 3 < -(x – 3)
2. Solve each equation separately
(a) Equation (1)
[tex]\begin{array}{rcl}x - 3 & < & x - 3\\x & < & x\\\end{array}\\\text{This is impossible. No solutions exist.}[/tex]
(b) Equation (2)

what is the value of x?
Answer:
x = 3Step-by-step explanation:
∠QRT and ∠SRT are supplementary angles,
therefore m∠QRT + m∠SRT = 180°.
(45x)° + m∠SRT = 180° subtract (45x)° from both sides
m∠SRT = 180° - (45x)°
We know: the sum of the measures of the angles of the triangle is equal to 180 °. Therefore we have the equation:
(180 - 45x) + (57 + x) + 25x = 180 combine like terms
(-45x + x + 25x) + (180 + 57) = 180
-19x + 237 = 180 subtract 237 from both sides
-19x = -57 divide both sides by (-19)
x = 3

in a concert hall, 250 seats out of 300 were occupied. to the nearest thousand, what part of the hall was not occupied?
Answer: 0.167 is the part of the hall that was not occupied. Or 16.7 %
Step-by-step explanation:
300-250=50 this is the number of seats not occupied since 250 is the amount occupied.
So, 50/300=5/30 which can be converted to a number which is 0.1666666667. It says to round to the thousandths place, which is the 3rd number. That is 0.167
Answer:
0.167 part of the hall was not occupied
Step-by-step explanation:
Given :In a concert hall, 250 seats out of 300 were occupied.
To Find :To the nearest thousand, what part of the hall was not occupied?
Solution:
Total seats = 300
Occupied seats = 250
Unoccupied seats = 300-250 = 50
So, The part of the hall was not occupied = [tex]\frac{\text{unoccupied seats}}{\text{total seats}}[/tex]
= [tex]\frac{50}{300}[/tex]
= [tex]0.167[/tex]
Hence 0.167 part of the hall was not occupied

Answer:
720/1681
Step-by-step explanation:
First quadrant so everything is positive for a trig function of just the angle. I would suggest just drawing a right triangle using tan(x)=40/9 (opp/adj). Find the hypotenuse which is sqrt(40^2+9^2)=sqrt(1600+81)=sqrt(1681)=41. So sin(x)=40/41 and cos(x)=9/41.
Therefore sin(2x)=2sin(x)cos(x)=2(40/41)(9/41)=720/1681
The width of rectangular field is x metres.
The length of the field is 30m longer than the width.
The perimeter of the field is less than 500m.
The area of the field is greater than 4000m^2
By writing suitable inequalities, find the possible values of x
Answer:
Possible values of x are 50 < x < 110.
Step-by-step explanation:
Consider the perimeter of the field:
2x + 2(x + 30) < 500
2x + 2x + 60 < 500
4x < 440
x < 110.
Consider the area of the field:
x(x + 30 ) > 4000
x^2 + 30x - 4000 > 0
(x - 50)(x + 80) > 0
The critical values are x = -80 and 50.
As x is a width it must be positive so x > 50.

C. By finding the quotient of the bases to be 1/3 and simplifying the expression
D. By finding the quotient of the bases to be 1/3 and cancelling common factors
Answer:
B. By simplifying 9 to [tex]3^{2}[/tex] to make both powers base three and subtracting the exponents
Step-by-step explanation:
When you have a division the quotient of powers property states that the exponents should be substracted, and by simplifying 9 to [tex]3^{2}[/tex] you end up with an equation like this:
[tex]\frac{3^{4} }{3^{2} }[/tex]=[tex]3^{2}[/tex]
Then you just have to substract the exponent from the denominator from the numerator´s exponent, which would be:
4-2=2
and the resultant equation would be:
[tex]3^{2} =3^{2}[/tex]
The Quotient of Powers Property allows you to subtract exponents when dividing expressions with the same base. The expression 3^4/9 simplifies to 3^2 because 9 can be expressed as 3^2, therefore their exponents are subtracted (4-2=2).
Explanation:In this question, the Quotient of Powers Property is used. This property states that to divide where the base remains the same, you subtract the exponents. In the expression 3^4/9 = 3^2, we know that 9 can be expressed as 3^2.
Therefore, it becomes 3^4/3^2. According to the Quotient of Powers Property, we subtract the exponent of the denominator from the exponent of the numerator (4-2=2). Hence the expression simplifies to 3^2. The correct choice is B: By simplifying 9 to 3^2 to make both powers base three and subtracting the exponents.

$22.50 + $2.50(x-1) = $30
$22.50 + $2.50x - $2.50 = $30
$2.50x = $10.50
x = 4.2 hours
Therefore, you can park for 4.2 hours for $30 in the garage.
