The product of two numbers is 40. if one of the numbers is 5/11, what is the other number?
Answers
Final answer:
To find the other number when the product of two numbers is 40 and one of the numbers is 5/11, we divide 40 by 5/11 to solve for the unknown number. The other number is found to be 88.
Explanation:
The question asks to find the other number when the product of two numbers is 40 and one of the numbers is given as 5/11. To do this, we can set up an equation where the product of 5/11 and the unknown number (which we can call 'x') is equal to 40.
The equation would be: (5/11) × x = 40. To solve for x, we need to do some algebraic rearrangement by dividing both sides of the equation by 5/11. This brings x into the numerator on the left side and shifts the 5/11 to the denominator on the right side. Therefore, we get x = 40 × (11/5).
Next, we multiply 40 by 11/5. This calculation results in x = 88. Thus, the other number is 88.

We have function [tex]f(x)=3(2.5)^x[/tex]
From the graph we can see that as x decreases without bound the graph of f(x) approaches y=0.
Also the exponential function in the graph is approaching y=0 as x decreases on the left side of the curve.
Here as the exponential function here the power is x variable and the exponential function cannot be negative for any value of x.
Therefore as x increases without bound, the graph of f(x) approaches y=0 increases without bound .

How can sums and differences of cubes be identified for factoring?
Answers
a³ + b³ = (a + b)(a² - ab + b²)
Example for the sum of cubes:
64x³+y³ ⇒ This is the sum of cubes because each term; 64, x³, and y³ are cube numbers
By writing each term as an expression of cube numbers, we have:
(4x)³ + (y)³ ⇒ 64 is 4³
Use the factorization of the sum of cubes, we have:
(4x + y) ( (4x)²- 4xy + y²)
(4x + y) (16x² - 4xy + y²)
--------------------------------------------------------------------------------------------------------------
The difference of cubes can be factorized as:
(x³ - y³) = (x - y)(x² + xy + y²)
Example
(125x³ - 8y³) = (5x - 2y) ((5x)² + (5x)(2y) + (2y)²)
= (5x - 2y) (25x² + 10xy + 4y²)
The equation of line m is 5x−3y=2. What is the slope of a line that is perpendicular to line m? Enter your answer in the box.
Answers
y=-5/-3x+2/-3
y=5/3x-2/3
compare y=mx+c || m =5/3
for perpendicularity
m=-1/M
m=-1/5/3
m= -3/5
Step 1
Find the slope of the line M
we have
[tex]5x-3y=2[/tex]
isolate the variable y
[tex]3y=5x-2 \\ \\y=\frac{5}{3}x-\frac{2}{3}[/tex]
the slope of the line is [tex]\frac{5}{3}[/tex]
Step 2
Find the slope of the line perpendicular to line M
we know that
if two lines are perpendicular , then the product of their slopes are equal to minus one
so
[tex]m1*m2=-1[/tex]
we have
[tex]m1=\frac{5}{3}[/tex]
Find m2
[tex]m2=-1/m1[/tex]
[tex]m2=-1/(5/3)[/tex]
[tex]m2=-\frac{3}{5}[/tex]
therefore
the answer is
[tex]-\frac{3}{5}[/tex]

We will use the log rule that log(x^y) = y*log(x). Call this log rule 1. This log rule basically allows us to pull the exponent down.
Another log rule that we will use is [tex]\log_x\left(x\right) = 1[/tex] where x is any positive real number but x = 1 is NOT allowed. Call this log rule 2.
Because 36 = 6^2, this means that 1/36 = 6^(-2)

So,
[tex]\log_6\left(\frac{1}{36}\right)=\log_6\left(\frac{1}{6^2}\right)[/tex]
[tex]\log_6\left(\frac{1}{36}\right)=\log_6\left(6^{-2}\right)[/tex]
[tex]\log_6\left(\frac{1}{36}\right)=-2*\log_6\left(6\right)[/tex] Use log rule 1 (see above)
[tex]\log_6\left(\frac{1}{36}\right)=-2*1[/tex] Use log rule 2 (see above)
[tex]\log_6\left(\frac{1}{36}\right)=-2[/tex]
This means that the given expression simplifies to -2
You can use a calculator to type in "log(1/36)/log(6)" without quotes and you should get -2 as the answer
so 6² = 36
therefore, 6⁻² = [tex] \frac{1}{36} [/tex]

Which is an example of a function?
the time it takes to mow a lawn and the age of the person mowing the lawn
the distance to school and the time you spend at school
the price of a movie ticket and the height of the customer
the price of a piece of cloth and the length of the cloth
Answers
The example of a function is:
The price of a piece of cloth and the length of the cloth.
Step-by-step explanation:We know that a function is a relation in which each element of a set is mapped to a single element of the other set.
i.e. an element has just one image.
1)
The time it takes to mow a lawn and the age of the person mowing the lawn.
This is not a example of function since, the time taken by two person's of different age may be same to mow a lawn.
This means that there is more than one image of a single element i.e. time.
2)
The distance to school and the time you spend at school.
The time one spend at school at different days may be different even if the distance to school is same.
3)
The price of a movie ticket and the height of the customer.
Two person's with different height will buy a movie ticket at the same cost.
Hence, this relation won't be a function.
4)
The price of a piece of cloth and the length of the cloth.
As we know that the price of a cloth is fixed according to the length.
Hence, the relation is a function.
( As corresponding to each price we have a unique length if a piece of clothing )
holly and melanie were playing a video game. the ratio of holly's score to melanie's score was 8:3. after melanie scored 34 points, the ratio of their scores became 2:5. what were their scores at the end?
Answers
Since we don't know the actual numbers, let's say their scores were originally 8x for Holly and 3x for Melanie.
Then Melanie scored 34 points, so her score became 3x + 34.
Holly's score remained the same at 8x.
The new ratio is 2:5, so
8x/(3x + 34) = 2/5
Now we solve the equation for x.
40x = 6x + 68
34x = 68
x = 2
With x, we can find the scores.
Holly ended up with 8x = 8 * 2 = 16
Melanie ended up with 3x + 34 = 3(2) + 34 = 40

The baggage limit for an airplane is set at 100 pounds per passenger. thus, for an airplane with 200 passenger seats there would be a limit of 20,000 pounds. the weight of the baggage of an individual passenger is a random variable with a mean of 95 pounds and a standard deviation of 35 pounds. if all 200 seats are sold for a particular flight, what is the probability that the total weight of the passengers' baggage will exceed the 20,000-pound limit?
Answers
At a mean of 95 pounds per passenger and standard deviation of 35 pounds, multiplying this with the total number of passengers = 200, results in:
absolute mean = 95 * 200 = 19,000
absolute std dev = 35 * 200 = 7,000
Calculating for the z score:
z = (x – u) / s
where x is sample value = more than 20,000; u is the sample mean = 19,000; s is std dev = 7,000
z = (20,000 – 19,000) / 7,000
z = 0.143
From the distribution tables,
P (z = 0.14) = 0.5557
Therefore a 55.57% chance that it will be more than 20,000 pound limit
Final answer:
Using the Central Limit Theorem, we calculate the probability that the total weight of passengers' baggage exceeds 20,000 pounds for an airplane with 200 passengers to be approximately 0.0217.
Explanation:
To solve this problem, we use the Central Limit Theorem which states that if we have a large enough sample size, the distribution of the sample means will be approximately normally distributed regardless of the original distribution's shape. Given that the mean weight of an individual passenger's baggage is 95 pounds with a standard deviation of 35 pounds, and that there are 200 passengers, we can calculate the mean and standard deviation of the total baggage weight.
The mean total weight, μtotal, is calculated as the product of the mean individual weight and the number of passengers, so μtotal = 95 pounds × 200 = 19,000 pounds. The standard deviation of the total weight, σtotal, is calculated as the standard deviation of the individual weight multiplied by the square root of the number of passengers, so σtotal = 35 pounds × √200 ≈ 494.97 pounds.
Using the standard normal distribution, we find the z-score for the probability that the total weight exceeds 20,000 pounds by subtracting the mean from the limit and dividing by the standard deviation: z = (20,000 - 19,000) / 494.97 ≈ 2.02.
Looking up this z-score in a standard normal table or using a calculator, we find that the probability of the total baggage weight exceeding 20,000 pounds is approximately 0.0217.
M(8, 5) is the midpoint of JK. The coordinates of point J are (5, −6) . What are the coordinates of point K?
Answers
The midpoint is the exact middle of a line segment which divides the line into two equal lengths. Hence, the coordinate of K is (11, 16)
We can obtain the distance between the coordinates of JM thus :
Distance = y2 - y1 ; x2 - x1
Distance = (8 - 5) ; (5 - (-6) = (3, 11)
Hence, the change in the coordinates is (3, 11)
Therefore, the coordinates of K can be obtained thus :
(8 + 3) ;(5 + 11) = (11, 16)
Hence, the coordinate of K is (11, 16)
