Answer:
4 (as in 25/4)
Step-by-step explanation:
Write and solve an equation of ratios:
x 15
------ = ------
10 24
Then 24x = 150, and x = 150/24 = 6.25. This is equivalent to 25/4.
Answer:
x = 25/4
Step-by-step explanation:
If the rectangles are similar, the ratio of the side lengths have to be similar
10 24
------ = --------
x 15
Using cross products
10*15 = 24*x
150=24x
Divide each side by 24
150/24=24x/24
150/24=x
Divide the top and bottom by 6
25/4 = x
What are the excluded values of the function? y= 5/6x-72
Answer:
x = 12 is the excluded value
Step-by-step explanation:
An excluded value is the value/s of x that make the denominator of the rational function equal to zero as this would make the function undefined.
Equate the denominator to zero and solve for x
6x - 72 = 0 ⇒ 6x = 72 ⇒ x = 12 ← excluded value
Answer: x=12

what is the interquantile range between 3 & 8?
Answer:
8 - 3 =5
5 is the range of the values given
Step-by-step explanation:
We are only given 2 values;
3 and 8
It seems more reasonable to compute the range of these values as a measure of spread.
The range of a data-set is simply the difference between the maximum and the minimum values.
In our case, the maximum is 8 while the minimum is 3. The range is thus;
8 - 3 = 5
Final answer:
The interquartile range (IQR) is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). If Q1 is 3 and Q3 is 8, the IQR is 5.
Explanation:
The interquartile range (IQR) is the range of the middle 50 percent of the data values, calculated by subtracting the first quartile (Q1) from the third quartile (Q3). If the student asks about the interquartile range between 3 and 8, it seems that they may be referring to the quartiles directly, which would be unusual since quartiles are typically values derived from the data set. However, if we assume that in this case, 3 represents Q1 and 8 represents Q3, then the IQR can be calculated simply as:
IQR = Q3 - Q1 = 8 - 3 = 5.
The IQR indicates the spread of the central half of a data set and is useful in identifying potential outliers and understanding the distribution of data.
Calculate the finance charge and new balance using the previous balance method. Previous balance = $199.19 Annual rate = 14% Finance charge = $ New purchases = $97.50 Payments/credits = $75.75 New balance = $
To calculate the finance charge and new balance, first find the finance charge with the formula: Previous balance x Annual rate / 12 months. Add this to the previous balance and any new purchases, then subtract any payments or credits. The resulting figure will be the new balance. In this example, the finance charge is $2.32 and the new balance is $223.26.
Explanation:In this financial calculation, the annual rate of 14% is used to calculate the finance charge on the previous balance of $199.19. The formula to calculate the finance charge is: Previous balance x Annual rate / 12 months. Moving forward, the finance charge will be added to the previous balance and any new purchases, then any payments or credits will be subtracted from this total to find the new balance.
Calculate the finance charge. Finance charge = (199.19 x 0.14) / 12 = $2.32.Add the finance charge to the previous balance and new purchases. $199.19 (previous balance) + $2.32 (finance charge) + $97.50 (new purchases) = $299.01.Subtract payments or credits from the previous total to find the new balance. New balance = $299.01 - $75.75 (payment) = $223.26.Learn more about Finance charge calculation here:https://brainly.com/question/15720230

Marie is purchasing a $105,000 home with a 30 year mortgage at 5.25%. What’s her monthly principal and interest payment?
A. $414.73
B. $503.23
C. $556.09
D. $579.81
Answer:
Her monthly principal payment is D: $579.81 and monthly interest payment is 0.4375.
Step-by-step explanation:
Ok, in order to calculate the monthly principal and interest payment, we can use this relatively simple equation. The equation is:
[tex]M=P\frac{r(1+r)^{n} }{((1+r)^{n}-1) }[/tex]
Where variables represent the following:
M is your monthly payment.
P is your principal.
r is your monthly interest rate, calculated by dividing your annual interest rate by 12.
n is your number of payments (the number of months you will be paying the loan throughout the 30 years)
Then, in this case:
M=?
P=$105,000
5.25%=5.25/100=0.0525, then [tex]r=\frac{0.0525}{12} =0.004375[/tex]
[tex]n=12*30=360[/tex]
So, [tex]M=105,000\frac{0.004375(1+(0.004375))^{360} }{((1+(0.004375))^{360}-1)}[/tex] $
Solving this,
[tex]M=105,000\frac{0.004375(1.004375))^{360} }{((1.004375))^{360}-1)}[/tex] $
[tex]M=105,000\frac{0.004375(4.8141) }{((4.8141))-1)}[/tex] $
[tex]M=105,000\frac{0.02106 }{3.8142}[/tex] $
[tex]M=105,000(0.005522)/tex] $
[tex]M=579.81[/tex] $
Her monthly principal payment is $579.81.

given that (-3,6) is on the graph of f(x), find the corresponding point for the function 1/3f(x)
Answer:
The corresponding point of (-3 , 6) is (-3 , 2)
Step-by-step explanation:
* Lets talk about some transformation to solve the problem
- A vertical stretching is the stretching of the graph away from
the x-axis
- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched
by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
- If 0 < k < 1 (a fraction), the graph is f(x) vertically compressed
by multiplying each of its y-coordinates by k.
* Now lets solve the problem
∵ f(x) transformed to be 1/3 f(x)
∴ The graph of f(x) is stretched or compressed vertically
∵ k = 1/3
∴ 0 < k < 1
∴ The graph is compressed vertically
- The y-coordinate must be multiplying by k
∵ The y-coordinate of the point is 6
∵ 6 × 1/3 = 2
∴ The image of the point (-3 , 6) is (-3 , 2)
* The corresponding point of (-3 , 6) is (-3 , 2)

Answer:
[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4x-y}{3y}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(4x - y) = 3y ← distribute left side
8x - 2y = 3y ( add 2y to both sides )
8x = 5y ( divide both sides by 8 )
x = [tex]\frac{5}{8}[/tex] y ( divide both sides by y )
[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{8}[/tex]

Answer:
m∠1 = 123°
Step-by-step explanation:
Since a straight line is always a supplementary angle, it equals 180°. To solve for the unknown angle, we can subtract the known angle from 180°.
180° - 57° = 123°
So m∠1 = 123°
180-57= 123 is the measurement for angle 2
All straight line is equal to 180

I need to find AB and DE
Answer:
AB = 21 and DE = 23
Step-by-step explanation:
Given 2 intersecting chords inside the circle then
The products of the measures of the parts of one chord is equal to the products of the measures of the parts of the other chord, that is
x(x + 13) = (x + 10)(x + 1) ← distribute parenthesis on both sides
x² + 13x = x² + 11x + 10 ← subtract x² + 11x from both sides
2x = 10 ( divide both sides by 2 )
x = 5
Hence
AB = x + 10 + x + 1 = 2x + 11 = (2 × 5) + 11 = 10 + 11 = 21
DE = x + x + 13 = 2x + 13 = (2 × 5) + 13 = 10 + 13 = 23

Analyze Lara’s work. Is she correct? If not, what was her mistake?
Yes, she is correct.
No, she used the diameter instead of the radius measure.
No, she should have multiplied 4 and 10 first before applying the exponent.
No, her units should be squared for volume.
Answer:
No, she used the diameter instead of the radius measure.
Step-by-step explanation:
we know that
The volume of the sphere is equal to
[tex]V=\frac{4}{3}\pi r^{3}[/tex]
we have
[tex]r=10/2=5\ units[/tex] ----> the radius is half the diameter
substitute
[tex]V=\frac{4}{3}\pi (5)^{3}[/tex]
[tex]V=\frac{500}{3}\pi\ units^{3}[/tex]
Answer:
No, she used the diameter instead of the radius measure.
Step-by-step explanation:
The formula for the sphere is:
[tex]\pi \frac{4}{3} r^{3}[/tex]
So she should have calculated the radius before inserting the values into the formula, the radius is half the diameter, so the radius of that sphere is 5.
In order to calculate it right you have to put 5 instead of the 10 so teh formula would look like this:
[tex]\pi \frac{4}{3} r^{3}[/tex]
[tex]\pi \frac{4}{3} 5^{3}[/tex]
[tex]\pi \frac{4}{3}(125)[/tex]

naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read
write the functions formula
Answer:
Step-by-step explanation:
The question here is "how many pages does this book have?"
In 4 hrs, at 55 pages/hr, he reads 220 pages.
Adding the number of pages read (220) to the number of pages left to read (350) yields a total of 570 pages in this book.
Next time, please try to be more specific about what you want to find. "functions formula" is very ambiguous and unhelpful.
The equation is [tex]\( y = 570 - 55x \)[/tex], where [tex]\( y \)[/tex] is pages left and [tex]\( x \)[/tex] is hours passed.
To complete the equation for the relationship between the number of pages left and the number of hours, we first need to determine the rate at which Naoya is reading the book.
Since he read 55 pages per hour, after 4 hours he would have read [tex]\( 55 \times 4 = 220 \)[/tex] pages.
Given that after 4 hours he still had 350 pages left to read, we can find out how many pages he had initially:
Initial number of pages = Total pages - Pages read
Initial number of pages = 350 pages + 220 pages
Initial number of pages = 570 pages
Now, let's use the formula for the relationship between the number of pages left and the number of hours:
[tex]\[ y = 570 - 55x \][/tex]
Where:
- [tex]\( y \)[/tex] represents the number of pages left to read after [tex]\( x \)[/tex] hours.
- [tex]\( x \)[/tex] represents the number of hours.
So, the complete equation for the relationship is:
[tex]\[ y = 570 - 55x \][/tex]
The complete question is here:
Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.
Let y represent the number of pages left to read after x hours.
Complete the equation for the relationship between the number of pages left and number of hours.

Jessie has some chickens and rabbits. There are 30 heads and 76 legs in all. How many chickens
does Jessie have and how many rabbits does Jessie have?
Answer:
8 rabbits
22 chickens
Step-by-step explanation:
c = chickens
r = rabbits
heads - c + r = 30
legs - 2c + 4r = 76
We can now use these two equations to create one by isolating the variable (c) in the first equation.
c = 30 - r
2c + 4r = 76
2(30 - r) + 4r = 76
60 - 2r + 4r = 76
2r = 16
r = 8
Now we know that there are 8 rabbits, which means that there has to be 22 chickens in order to have 30 heads.
To solve the problem of finding the number of chickens and rabbits, we can use a system of equations.
Explanation:To solve this problem, we can use a system of equations. Let's consider the number of chickens as 'c' and the number of rabbits as 'r'.
We know that there are a total of 30 heads, which means that c + r = 30.
We also know that there are a total of 76 legs, which means that 2c + 4r = 76.
We can solve this system of equations by substitution or elimination to find the values of c and r. From there, we can determine the number of chickens and rabbits that Jessie has.
Let's solve it using the elimination method: Multiply the first equation by 2 to match the coefficient of 'c' in the second equation. You will get 2c + 2r = 60. Subtract this equation from the second equation to eliminate 'c', and you will get 2r - 2r = 76 - 60. Simplifying, we have 0 = 16, which is not true.
There is no solution for this system of equations. Therefore, the problem may be set up incorrectly.
