In a fraction, the numerator is 12 less than the denominator. When simplified, the fraction is equal to 3/5 . What is the fraction before it is simplified?
Answers
Step-by-step explanation:
Denominator =X
Numerator = X-12
Fraction = (X-12)/X
⇛(X-12)/X = 3/5
⇛5(X-12) = 3X
⇛5X-60 = 3X
⇛5X-3X = 60
⇛2X = 60
⇛X = 60/2
⇛X = 30
Denominator = 30
Numerator = 30-12 = 18
The fraction before simplified = 18/30

So that would make the formula: (3.14)R^2-(3.14)r^2 = A
The only unknown variables that you need to find are the radii of the two circles
The smaller circle:
You are given the diameter, and the diameter is 1/2 the radius,
so r= 1/2(11.25) = 5.625
The larger circle:
You are given the width, which is the total added onto the diameter of the smaller circle so:
(11.25+3.75)/2=7.5
and now that you know R, you can plug into the equation found at the start: (3.14)R^2-(3.14)r^2 = A
(3.14)(7.5^2)-(3.14)(5.625^2)=A
A=176.71-99.35
A=77.36 ft^2

Answers
The height of the ball at time t is modeled by
\(H(t)=3+29t-16t^2\)To find the values of t for which the height is 15 feet, let us solve the equation
\(\begin{gathered} H(t)=15 \\ 3+29t-16t^2=15 \\ 16t^2-29t+12=0 \\ x=\frac{29\pm\sqrt[]{73}}{32} \\ =0.64,1.17 \end{gathered}\)So, at t=0.6 sec and =1.173 sec, the height of the ball is 15 feet (Rounding off to the nearest hundredth)

x = √(-1) = i
Since the value of √(-1) is not real.
The system has no real solution.
Step-by-step explanation:
The solution to the system of equations is at the point where they intercept each other.
y1 = y2
For the given equation;
y=x^2-2x and y=-2x-1
To get the where they intercept, we will equal both equations;
y=x^2-2x = -2x-1
x^2 - 2x = -2x - 1
x^2 - 2x + 2x + 1 =0
x^2 +1 = 0
x^2 = -1
x = √(-1) = i
Since the value of √(-1) is not real.

Round your answer to the hundredths place and show all necessary math work. (3 points)
Answers
Given:
There are given that the Appalachain trail planned to increase the distance covered by 20%.
Explanation:
(a):
According to the question:
We need to find the number of miles did the hiker travel on the first.
So,
To find the number of miles, we use the below equation:
\(51.664=\frac{(x(1.2)^7-1)}{0.2}\)Then,
\(\begin{gathered} 51.664=\frac{(x(1.2)^{7}-1)}{0.2} \\ 10.33=(x(1.2)^7-1) \\ 10.33=2.6x \\ x=\frac{10.33}{2.6} \\ x=4 \end{gathered}\)Hence, he started with 4 miles.
Part B:
According to the question:
There are given 7 days.
So,
We get the second part of the equation because each day is increased by 20%.
So, we have:
\(r=\frac{1.2x}{x}=1.2\)So,
Our top half will be x multiplied by:
\(((1.2)^7-1)\)Because it is the 7th day and we are increasing by:
\(1.2x-1\)So,
The equation is shown below:
\(51.664=\frac{(x(1.2)^{7}-1)}{0.2}\)Part C:
We now have x which is 4.
So,
We plug x into the equation above and remove the 51.664.
Then,
We also change the expression:
\((1.2)^7,to,(1.2)^{10}\)Because it's the 10th day, not the 7th.
So,
Our equation now looks like this:
\(\frac{(4(1.2)^{10}-1)}{0.2}=103.83\)Hence, the total number of miles the hiker will travel in 10 days is 103.83.

A square root function that is represented by the graph include the following: A. f(x) = √(4x + 8).
What is a square root function?In Mathematics and Geometry, a square root function can be defined as a type of function that typically has this form f(x) = √x, which basically represent the parent square root function i.e f(x) = √x.
In Mathematics and Geometry, a horizontal translation to the left is modeled by this mathematical equation g(x) = f(x + N) while a vertical translation to the positive y-direction (downward) is modeled by this mathematical equation g(x) = f(x) - N.
Where:
N represents an integer.g(x) and f(x) represent functions.Therefore, the required square root function is given by;
f(x) = √(4x + 8)

Find the area of this composite figure:
A=189.25in2
True
False
Answers
Area of the composite figure is 189.25 in². Therefore, the given area A of the figure is Ture.
First, let us find the area of the rectangle.
Area = Length × Width
= 15 in × 10 in
= 150 in²
Then let us find the area of the semicircle.
Area = \(\frac{1}{2}\) × π r²
= \(\frac{1}{2}\) × 3.14 × 5 × 5
= 0.5 × 3.14 × 25
= 1.57 × 25
= 39.25 in²
Now let us find the total area of the composite figure.
Total area = Area of the rectangle + Area of the semi-circle.
= 150 in² + 39.25 in²
= 189.25 in²
Area of the composite figure is 189.25 in². Therefore, the given area A of the figure is Ture.

< ABC = 46 degreesWhat are perpendicular bisectors?In geometry, a perpendicular bisector is a line or line segment that divides another line segment into two equal parts and is perpendicular to it.
From the definition of perpendicular bisector, we have that
< A = < C
and using triangle ABD
< A + < ABD = 90
< A + 28 = 90
< A = 90 - 28
< A = 62
Using triangle ABC
< A + < ABC + < C = 180
62 + < ABC + 62 = 180
< ABC = 180 - 62 - 62
< ABC = 56
OR
< ABD = < DBC = 28 degrees

Among the given answer choices, the correct option that represents this range is "0 100 200 none of the answer choices".
To determine the range of the number of RVs that need to be sold each month for the company to make a profit, we need to consider the profit function and find the values of x that result in a positive profit.
The profit function is given by P(x) = -50x + 20,000x - 1,500,000.
To make a profit, the value of P(x) must be greater than zero (P(x) > 0). We can set up the inequality:
-50x + 20,000x - 1,500,000 > 0.
Combining like terms, we have:
19,950x - 1,500,000 > 0.
Now, let's solve this inequality for x:
19,950x > 1,500,000.
Dividing both sides by 19,950, we get:
x > 1,500,000 / 19,950.
Simplifying the right side, we have:
x > 75.
The range of the number of RVs that need to be sold each month for the company to make a profit is x > 75.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 20 miles per hour slower than the westbound train. If the two trains are 360 miles apart after 2 hours, what is the rate of the eastbound train?
Answers
Answer:
Westbound = x;
Eastbourne = x-20;
So they will have the common rate: 360/2 = 180;
x+x-20 = 180
2x = 200;
x = 100;
So Eastbourne will be 100-20 = 80 miles per an hour;
