Answer:
A is the answer.
Step-by-step explanation:
A fraction plus a fraction is equal to a fraction. An irrational number cannot be expressed as a fraction.
0.3333333 even though it looks like an irrational number it is actually: 1/3
3/5 is already a fraction so adding it with another fraction will NOT equal an irrational number (decimal)
-0.75 is equal to -3/4 (75/100 => 3/4). Same thing that applies above.
However, Pi cannot be expressed as a fraction exactly. You can round up like 3.14. However it is not the full number. So 3.141592654....+(3/4) is not going to add up perfectly into a fraction.
In short, a fraction is a rational number. Rational + Rational = Rational. Irrational + Rational = Irrational.
Answer:
A (pi)
Step-by-step explanation:
Pi is already an irrational number, therefore, anything added to it must become irrational

Find M
A) 105°
B) 102°
C) 51°
D) 204°
Answer:

Step-by-step explanation:
i did jajajajajajaja jajajajjaja
the measure of angle X is [tex]\( 104^\circ \).[/tex]
To calculate the measure of angle X in a kite-shaped scenic overlook, we'll follow these steps:
Write the equation representing the sum of the measures of all the angles in the kite, which is [tex]\( 360^\circ \).[/tex]
Identify the two angles that are equal in the kite, which are angles X and Z.
Write the equation representing the sum of these angles and the given angle measures.
Solve for the measure of angle X.
Now, let's perform the calculation:
Equation representing the sum of the measures of all the angles in the kite:
[tex]\[ \angle X + \angle Y + \angle Z + \angle W = 360^\circ \][/tex]
Identify the two equal angles:
Since the kite has two pairs of adjacent sides that are equal, the angles opposite these sides will be equal. So, [tex]\( \angle X = \angle Z \).[/tex]
Write the equation representing the sum of these angles and the given angle measures:
[tex]\[ \angle X + 40^\circ + \angle X + 112^\circ = 360^\circ \][/tex]
Solve for the measure of angle X:
[tex]\[ 2\angle X + 152^\circ = 360^\circ \] \[ 2\angle X = 360^\circ - 152^\circ \] \[ 2\angle X = 208^\circ \] \[ \angle X = \frac{208^\circ}{2} \] \[ \angle X = 104^\circ \][/tex]
So, the measure of angle X is [tex]\( 104^\circ \).[/tex]

How many degrees are in the period of y = cos (3x)
Answer:
Step-by-step explanation:
cos(3x)=cos (3x+2π)=cos (3x+360)
period for 3x=360°
period=360/3=120°
Final answer:
The period of the function y = cos(3x) is π/3 or 120 degrees, since the coefficient '3' in the function's argument compresses the usual period of cos(x) by a factor of three.
Explanation:
The period of a trigonometric function represents the length of one complete cycle of the function. For the function y = cos(3x), we are dealing with a cosine function that has been horizontally compressed by a factor of 3. The standard period of the cosine function is 2π radians. However, the presence of the 3 within the argument of the cosine function means that the period is reduced by a factor of 3, because the function completes its cycle 3 times faster than the standard cosine function.
To find the period of the given function, we divide the standard period of the cosine function by the coefficient of the x variable inside the function:
Standard period of cos(x) = 2πPeriod of cos(3x) = ÷ 3Calculated period = 2π / 3Therefore, the period of y = cos(3x) is π/3 or approximately 120 degrees.

What expression represents the volume of the cone, in
cubic units?
A. 2/3 pi x 3
B. 4/3 pi x 2
C. 2 pi x 3
D. 4 pi x 3
Option A) 2/3 πx³ is the expression that represents the volume of cone in cubic units.
Step-by-step explanation:
The general formula for the volume of the cone is given by,
⇒ 1/3 πx²h
where,
x is the radius of the base of cone.h is the height of the cone.It is given that,
Height of the cone is twice the radius of its base.
Therefore, the volume of the cone is represented as
⇒ Substitute h=2x in the volume of the cone volume.
⇒ 1/3 πx²(2x)
⇒ 2/3 πx³ cubic units.
Hence, option A) 2/3 πx³ is the expression that represents the volume of cone in cubic units.

Step-by-step explanation:
A school bought pens, each costing $1, and pencils, each costing $0.5. The cost of the whole purchase was $220. How many pens and pencils were purchased if there were 80 more pencils than pens?
Answer:
120 pens and 200 pencils
Step-by-step explanation:
Let the number of pencils bought be x while pens will be y.
Cost
Considering that a pen costs $1 then for y pens, the cost will be y*$1=$y
The pencils cost $0.5 then for x pencils the cost will be $0.5*x=$0.5x
Total cost is $220 hence expressed as
0.5x+y=220
Quantity
Since the number of pencils, x were more than number of pens, y by 80 pieces then
x=80+y
Since we initially had the equation 0.5x+y=220 then we substitute x with 80+y hence
0.5(80+y)+y=220
40+0.5y+y=220
1.5y+40=220
1.5y=220-40=180
y=180/1.5=120
Since x=y+80 and y is found to be 120 then
x=120+80=200
Help me find my answer please
Answer:
f = - [tex]\frac{19}{7}[/tex]
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition that f = - 19 when m = 14, thus
- 19 = 14k ( divide both sides by 14 )
- [tex]\frac{19}{14}[/tex] = k
f = - [tex]\frac{19}{14}[/tex] m ← equation of variation
When m = 2, then
f = - [tex]\frac{19}{14}[/tex] × 2 = - [tex]\frac{19}{7}[/tex]

A polygon with 4 sides is shown with its exterior angles. The exterior angles are 140 degrees, 34 degrees, 56 degrees, and x degrees. What is the value of x?
Given:
Given that the polygon has 4 sides with its exterior angles.
The exterior angles are 140°, 34°, 56° and x°
We need to determine the value of x.
Value of x:
We know that, the exterior angles of a polygon add up to 360°
Thus, we have;
[tex]140^{\circ}+34^{\circ}+56^{\circ}+x=360^{\circ}[/tex]
Adding the terms, we have;
[tex]230^{\circ}+x=360^{\circ}[/tex]
Subtracting both sides of the equation by 230, we get;
[tex]x=130^{\circ}[/tex]
Thus, the value of x is 130°
Final answer:
The value of the unknown exterior angle x in the quadrilateral is 130 degrees, calculated by subtracting the sum of the given exterior angles from the total sum of 360 degrees.
Explanation:
The student is asking about finding the value of an unknown exterior angle (x) in a quadrilateral. In geometry, the sum of the exterior angles of any polygon always equals 360 degrees. Given that three of the exterior angles are provided as 140 degrees, 34 degrees, and 56 degrees, we can find the value of the unknown exterior angle x degrees by subtracting the sum of these provided angles from 360 degrees.
First, we add the given angles:
140 degrees + 34 degrees + 56 degrees = 230 degrees
Next, we subtract the total from 360 degrees to get the value of x:
360 degrees - 230 degrees = 130 degrees
Therefore, the value of x, the unknown exterior angle of the quadrilateral, is 130 degrees.
The radius of a circle is 3 m. Find its area to the nearest tenth
Answer:
28.26
Step-by-step explanation:
3^2*3.14 = 28.26
To find area you square the radius and then multiply by 3.14 or π pi
Rounded to the nearest tenth, the area of the circle is approximately 28.3 square meters.
To find the area of a circle, we can use the formula:
Area = π (radius)²
Given that the radius is 3 meters, we substitute this value into the formula:
Area = π(3²)
Area = 9π
Since we are asked to round the area to the nearest tenth, we can approximate the value of π as 3.14:
Area ≈ 3.14 x 9
Area ≈ 28.26
Rounded to the nearest tenth, the area of the circle is approximately 28.3 square meters.
The area of a circle is calculated by multiplying the square of its radius by the mathematical constant π (pi). In this case, with a radius of 3 meters, the area is approximately 28.3 square meters. Rounding the decimal to the nearest tenth gives us the final result of 28.3 square meters.

what is the value of x?
(geometry question)
Given:
The interior angles of the triangle are 44°, 3t - 45° and x - 15°
The exterior angle of the triangle is 4t - 29°
We need to determine the value of x.
Value of t:
The value of t can be determined using the exterior angle theorem.
Applying the theorem, we have;
[tex]44+3t - 45=4t-29[/tex]
[tex]3t - 1=4t-29[/tex]
[tex]-t - 1=-29[/tex]
[tex]-t=-28[/tex]
[tex]t=28[/tex]
Thus, the value of t is 28.
Value of x:
The exterior angle 4t -29 and the interior angle x - 15 are linear pairs.
Since, linear pairs add up to 180°, we have;
[tex]4t-29+x-15=180[/tex]
Substituting t = 28, we get;
[tex]4(28)-29+x-15=180[/tex]
[tex]112-29+x-15=180[/tex]
[tex]x+68=180[/tex]
[tex]x=112[/tex]
Thus, the value of x is 112.

Answer:
The third answer
Step-by-step explanation:
(side note: You probably need to use a calculator that can calculate pi)
The formula to find the area of a circle is pi r squared.
In this case, pi times r squared is 19.63495....... continued
This is probably going to be rounded
so... 19.63
For all of the circles, this is multiplied by 4.
This is 78.52
The area of the square is 100 cm since 10 times 10 is 100
You take 100 cm and then subtract it by 78.54
Voila! now you have 21.46
