Answer:
25/33
Step-by-step explanation:
Answer:
[tex]\frac{25}{33}[/tex]
Step-by-step explanation:
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.7575..... (1) ← multiply both sides by 100
100x = 75.7575... (2)
subtract (1) from (2) thus eliminating the repeating digits
99x = 75 ( divide both sides by 99 )
x = [tex]\frac{75}{99}[/tex] = [tex]\frac{25}{33}[/tex] ← in simplest form

the difference between two positive integers is 3. if the smaller is added to the square of the larger, the sum is 377. Find the integers
Answer:
let the smaller number be x and the larger number is y
y =x+3
x+y²=377
x+(x+3)²=377
x+(x+3)(x+3)=377
x+x²+3x+3x+9=377
x²+7x+9-377=0

what is the value of x ?
Let us first consider how many sides this figure has:
⇒ it has 6 sides
Now to find the supposed sum of all the angles added up together for a hexagon, must use:
⇒ [tex]Formula =(n-2)*180[/tex]
n: # of sidesLet's plug in the number of sides:
[tex]Sum_.of_.angles=(6-2)*180=720[/tex]
Therefore all the angles of a hexagon must equal 720 degrees:
[tex]x + 90 + 110+160+90+140=720\\x + 590=720\\x = 130[/tex]
The value of x is 130.
Answer: 130

Question 13 of 25
True or false? The graph represents a function
Answer:
B. False
Step-by-step explanation:
To determine if a graph represents a function, you can use the vertical line test. A graph is a function if no vertical line intersects the graph at more than one point. In this graph, a line can intersect the graph at more than one point, therefore, it is not a function.

A balloon artist claims the probability a randomly selected balloon pops while being molded is 0.10 and that balloons pop independent of other balloons. Part A. If we select a random sample of 3 balloons, what’s the probability that all of them pop while being molded?
Work Shown:
(0.10)^3 = (0.10)*(0.10)*(0.10) = 0.001
Answer:
0.001
Step-by-step explanation:
This can be modeled as a binomial distribution as:
There is a fixed number (n) of trialsEach trial is either a success or failureAll trials are independentThe probability of success (p) is the same in each trialThe variable is the total number of successes in the n trialsLet "success" be the balloon popping.
⇒ trials (n) = 3
⇒ probability of success (p) = 0.10
To find the probability that all 3 of the balloons pop, use the binomial distribution with x = 3:
[tex]\begin{aligned} \displaystyle P(X=x) & =\binom{n}{x} \cdot p^x \cdot (1-p)^{n-x}\\\\\implies P(X=3) & =\binom{3}{3} \cdot 0.1^3 \cdot (1-0.1)^{3-3}\\ & = 1 \cdot 0.001 \cdot 1\\ & =0.001 \end{aligned}[/tex]

write the equation in standard form for the circle passing through (-3,0) centered at the origin.
Answer:
x^2 + y^2 = 9
Step-by-step explanation:
The equation of a circle is (x^2) -a)^2 + (x^2) - b)^2 = r^2, where a and b are the center of the circle. Because the center of the circle is (0,0), it'll just be x^2+y^2 for one half of the equation. If the circle passes through (-3,0), that would mean the radius of the circle is 3. r^2 is 3^2, which is 9, so the equation of the circle is x^2 + y^2=9. Hope this helps!
The equation of the circle is x² + y² = 9
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the point be represented as A ( -3 , 0 )
Now , the center of the circle = O ( 0 , 0 )
And , standard form of a circle is
( x - h )² + ( y - k )² = r²
where In this case, we know that the circle passes through the point (-3, 0) and is centered at the origin (0, 0). Therefore, the radius of the circle is the distance from the origin to (-3, 0), which is:
r = √((-3 - 0)² + (0 - 0)²) = √(9)
r = 3 units
So the equation of the circle in standard form is:
(x - 0)² + (y - 0)² = 3²
On simplifying , we get
x² + y² = 9
Hence , the equation in standard form for the circle passing through (-3,0) centered at the origin is x² + y² = 9

Answer:
128 cubes can fit in.
Step-by-step explanation:
We are given: Volume of rectangular prism = 2 units³ and Cube with edge = 1/4 unit
We must find: The number of cubes that can fill the prism
Firstly, find the volume of 1 cube:
Volume = 1/4 x 1/4 x 1/4
Volume = 1/64 units³
Next find the number of cubes that can go into the prism:
Number of cubes = 2 ÷ 1/64
Number of cubes = 128
Therefore 128 cubes can fit in.

If f(x) = 3x - 2 and g(x) = 2x + 4, find (f - g)(x).
Answer:
(f - g)(x) = x - 6
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= [3x - 2] - [2x + 4]
= 3x - 2 - 2x - 4
= x - 6
(f - g)(x) = x - 6

Find the median and mean of the data set below:
47,15, 6, 49, 45, 30
Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.

There is a 2 kg book lying on a table. A 64 N force is applied to the book at a 120° angle from horizontal and moves the book 3 meters in the horizontal direction. How much work was done?
Answer:
156.32 joules
Step-by-step explanation:
In this case, we know the force of 64 N and the distance of 3 m. We also know that there is a 120°angle between the angle of the direction of applied force and the direction of motion. So plugging these values into our handy equation yields:
W = 64(3)cos(120)= 156.32 Joules
So the 64 N force at a 120° angle did 156.32 joules of work moving the book 3 meters.
A cylinder has a height of 6 meters and a radius of 3 meters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
169.56 m³
Step-by-step explanation:
» Concepts
The volume of a cylinder is how much space there is inside the cylinder. The formula to find the volume is πr²h, where r = radius and h = height. Once you get the volume, you have to add <unit>³.
» Application
We are given the radius as three meters and the height as six meters; we also have to use π as 3.14. Now, we just have to plug in these values into the aforementioned formula.

If r=1 and 0=5pie/3, what is the approximate arc length?
Answer:
5.236 units
Step-by-step explanation:
The relation between r, θ and arc length ( l ) is,
l = rθ
l = 1 * 5π / 3
( The value of π = 3.14 approximately )
5π = 5 x 3.14 = 15.7
l = 1 * 5π / 3
= 5π / 3
= 15.7/3
l = 5.236 units
Note : -
Arc length is denoted by " l ".
