Michelle is a dentist. One-third of her patients are under the age of 12. Five-twelfths of her patients are over the age of 65. What fraction of Michelle’s patients are 12 to 65 years old?
A: 1/6
B: 3/4
C: 3/5
D: 1/4
Answers
Simplifying this fraction gives us 1/4. The answer is (D) 1/4.
What is arithmetic sequence?
An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.
Let's start by finding the fraction of Michelle's patients who are under 12 or over 65. We know that one-third of her patients are under 12, so two-thirds must be 12 or older. Similarly, five-twelfths of her patients are over 65, so seven-twelfths must be 65 or younger.
Now, we want to find the fraction of Michelle's patients who are between 12 and 65. To do this, we need to subtract the fraction of patients who are under 12 or over 65 from 1 (since these are the only two age groups we're considering).
Fraction of patients under 12: 1/3
Fraction of patients over 65: 5/12
Fraction of patients 12 to 65: 1 - 1/3 - 5/12
We can simplify this expression by finding a common denominator:
Fraction of patients 12 to 65: 12/12 - 4/12 - 5/12
Fraction of patients 12 to 65: 3/12
Simplifying this fraction gives us 1/4. Therefore, the answer is (D) 1/4.

\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} 350 & 100\\ 140& x \end{array} \implies \cfrac{350}{140}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{5}{2} ~~=~~ \cfrac{100}{x}\implies 5x=200\implies x=\cfrac{200}{5}\implies x=40\)
Your digital camera has a 512 megabyte memory card. You take pictures at two resolutions, a low resolution requiring 4 megabytes of memory per photo and a high resolution requiring 8 megabytes of memory per photo. Write an equation to model the amount of each kind of photo you can take.
Answers
One possible answer is 8H + 4L = 512
=======================================================
Explanation:
H = number of high resolution photosL = number of low resolution photosH and L are placeholders for positive whole numbers, or 0 could replace either variable.
1 high resolution photo takes up 8 mb of space, so H of them take up 8H megabytes of space.
1 low resolution photo takes up 4 mb of space, so L of them take up 4L megabytes.
Overall, the two types of photos take up 8H+4L megabytes, which is equal to 512 since that's the max capacity. That leads to the equation 8H+4L = 512
----------------------------------
Extra info:
There are other ways to express the equation 8H+4L = 512. We could divide each part by 4 to get 2H+L = 128, but I think this equation loses its descriptive quality in a way. We no longer can see that each high resolution photo takes up 8 megabytes (instead we might mistakenly think only 2 megabytes are used per high resolution photo). A similar mistake may happen with the low resolution photos also.
The equation 2H+L = 128 can be rearranged into L = -2H+128 when solving for L.

1 dollar bill is 6.14 inches long 2.61 wide and 0.00043 thick. If you had 1 billion in 100 dollar bills the the number of bills would be
Answers
The number of 100 dollar bills in one billion dollars is 10 million hundreds or 70,900 hundred dollar bills.
To find the number of 100 dollar bills in one billion dollars, we can use the following steps:
First, we need to find the value of one billion dollars in terms of hundreds. Since each hundred dollar bill has a value of $100,
we can divide one billion by 100 to get the number of hundreds
\(:$$\frac{1\text{ billion}}{100}=10\text{ million}$$\)
So one billion dollars is equal to 10 million hundreds.
Now we need to find the volume of one hundred dollar bill. To do this, we multiply its length, width, and thickness:\($$6.14 \text{ in} \times 2.61 \text{ in} \times 0.00043 \text{ in}=0.00709 \text{ in}^3$$\)
The volume of one hundred dollar bill is approximately 0.00709 cubic inches.
Finally, we need to find the total volume of 10 million hundreds:\($$0.00709 \text{ in}^3 \times 10,000,000=70,900 \text{ in}^3$$\)
Therefore, the total volume of 10 million hundred dollar bills is approximately 70,900 cubic inches.10 million hundreds or 70,900 hundred dollar bills.

While riding "The Screamer" (an unreliable ferris wheel with a radius of 100 feet) you start getting nervous about how
high in the air you are...you estimate you're about 95 feet high in the air... how much could The Screamer have rotated
(round to the nearest whole degree). There are 2 answers
Answers
The Screamer could have rotated either about -2.87 degrees or 357.13 degrees from its starting position.
What is circumference?Circumference is the distance around the edge of a closed curve or a circle. It is the length of the boundary of a circular object or shape. In other words, it is the total length of the circular shape.
According to question:We can use trigonometry to determine the rotation's angle. The rider's height above the ground is equal to the ferris wheel's radius plus the distance travelled around its circle. Let's call the angle of rotation we're trying to find θ.
The distance traveled along the circumference of the wheel can be calculated as follows:
distance = θ/360 * 2πr
where r is the radius of the wheel. Substituting the given values, we get:
95 = 100 + θ/360 * 2π(100)
Simplifying the equation:
θ/360 = (95-100)/(2π(100))
θ/360 = -0.007957747
θ = -2.8661 degrees or 357.1339 degrees

The population of a town increased from 3800 in 2007 to 6100 in 2010 find the absolute and relative (percent) increase.
Answers
The requried population increased by approximately 60.53%.
To find the absolute increase, we subtract the initial population from the final population:
Absolute increase = Final population - Initial population
Absolute increase = 6100 - 3800
Absolute increase = 2300
Therefore, the population increased by 2300 people.
To find the relative increase, we first calculate the percent change:
Percent change = (New value - Old value) / Old value x 100%
Percent change = (6100 - 3800) / 3800 x 100%
Percent change = 2300 / 3800 x 100%
Percent change = 60.53%

What is an equation of the line that passes through the points (5,2) and (-5,6)?

Answer: y = -2/5x + 4
Steps:
First find the slope of the equation y=mx+b.
slope equation (m=y2-y1/x2-x1)
Then plug in your coordinates, which the first set is (5,2) and the second set if (-5,6). m = 6 - 2/ -5 - 5
Which your answer will be 4/-10, simplify it by dividing both by 2 to get -2/5 for your slope.
Next, find your y-intercept (b).
substitute the first set of coordinates into the equation y=mx+b
Substitute: 2 = -2/5 (5) +b
Then multiply -2/5 with 5 to get (-2). Your equation should now reduce to be
2 = -2 +b
Do inverse operations on both sides by adding 2 to each side (the 2 side and the -2+b side).
This gets rid of the -2 and since we added 2 to both sides, your final equation should look like 4 = b for your y-intercept.
Plug in everything to get y = -2/5x + 4

Find the missing endpoint if S is the midpoint RT. 1. R(9-4) and S(2,-1); find T
Answers
SOLUTION
We want to find the missing endpoint T in the line RT, given the point R(-9, 4) and the mid-point S(2, -1)
Since S is the mid-point, we will use the mid-point formula
\((x_m,y_m)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\)This becomes
\(S(2,-1)=(\frac{-9+x_2}{2},\frac{4+y_2}{2})\)This follows that
\(\begin{gathered} \frac{-9+x_2}{2}=2 \\ -9+x_2=4 \\ x_2=4+9 \\ x_2=13 \end{gathered}\)and

what is fraction?A fraction is a number that represents a portion of a whole or a ratio between two quantities in mathematics. It is represented as a top number (numerator) over a bottom number (denominator) divided by a horizontal line, also known as a vinculum. The fraction 3/4, for example, represents three-quarters of a whole that has been divided into four equal parts. Proper fractions, improper fractions, and mixed numbers are all ways to express a fraction. A suitable fraction is one in which the numerator is less than the denominator, for example, 2/5.
Mr. Bailey intends to plant soybeans on 4 of every 9 acres, which equates to (4/9) of the total acres he farms.
If he intends to cultivate 2,100 acres, the number of acres planted with soybeans is:
(4/9) x 2,100 = 933.33
We must round this amount to the next whole number because he cannot plant soybeans on a fraction of an acre.
