Step-by-step explanation:
Remark
Whatever the answer is (call it x to begin with), the equation starts as
5x + 3x + 2x = 240
What this means is that when you solve for x the results when multiplied by the ratio, should add to 240
Equation
5x + 3x + 2x = 240

Step-by-step explanation:
Jazmin takes a ride share service home from the airport. The ride share service charges $5 as an initial cost to pick her up, and $2.25 for every mile to her final destination. Jazmin's ride home cost a total of $38.75. Write an equation to represent the situation. Let m represent the number of miles to her home.
Answer:
38.75 = 2.25 m + 5
Step-by-step explanation:
It is given that :
Jazmin took a ride share service from airport to home.
The total cost of the ride service from airport to home is = $ 38.75
The ride service charged an initial cost for picker Jazmin = $ 5
Cost of the ride service for every mile = $ 2.25 per mile
Let the number of miles = m
Therefore, the equation that represents the situation is :
38.75 = 2.25 m + 5
where, m represents the number of miles.
The integral [, sin(x - 2) dx is transformed into S1, g(t)dt by applying an appropriate change of variable, then g() is: g(t) = sin g(t) = cos (5) O This option O This option g(t) = -cos (3) g(t) = sin O This option
By introducing the appropriate change of variable x = t + 2, we transformed the given integral [, sin(x - 2) dx] into S1, g(t)dt = [, sin(t) dt], where g(t) = sin(t). (option a)
To transform the given integral [, sin(x - 2) dx] into the form S1, g(t)dt, we need to apply a suitable change of variable. In this case, we'll introduce a new variable, t, and express x in terms of t. Let's denote this change of variable as x = h(t), where h(t) represents the transformation of t to x.
To determine the appropriate change of variable, we can start by looking at the expression inside the sine function: x - 2. We need to find a suitable expression for x that can help us simplify the integral. Let's set x - 2 equal to t:
x - 2 = t.
Now, we solve this equation for x to express it in terms of t:
x = t + 2.
Next, we differentiate both sides of the equation x = t + 2 with respect to t to find dx/dt:
dx/dt = d(t + 2)/dt.
Differentiating t + 2 with respect to t gives us:
dx/dt = 1.
Now, we have dx/dt = 1, which means dx = dt. We can substitute this value into the original integral:
[, sin(x - 2) dx] = [, sin(t) dt].
As you can see, the original integral [, sin(x - 2) dx] has been transformed into the form [, sin(t) dt] using the appropriate change of variable x = t + 2. Therefore, the integral S1, g(t)dt is now:
S1 = [, sin(t) dt],
and g(t) = sin(t).
Hence the correct option is (a).

Height of Brownies (cm) 2.15 2.43 2.71 2.99
A.
y = 0.28x + 0.75
B.
y = 0.75x +0.56
C.
y = 0.75x + 0.28
D.
y = 0.56x + 0.75
Answer:
A.
y = 0.28x + 0.75
Step-by-step explanation:
Check all that applies using teaspoons of baking powder, x = 5
A.
y = 0.28x + 0.75
When x = 5
y = 0.28x + 0.75
= 0.28(5) + 0.75
= 1.4 + 0.75
y = 2.15
B.
y = 0.75x +0.56
When x = 5
y = 0.75x +0.56
= 0.75(5) + 0.56
= 3.75 + 0.56
= 4.31
C.
y = 0.75x + 0.28
When x = 5
y = 0.75x + 0.28
= 0.75(5) + 0.28
= 3.75 + 0.28

D.
y = 0.56x + 0.75
When x = 5
y = 0.56x + 0.75
= 0.56(5) + 0.75
= 2.8 + 0.75

mad = (98 -96) + (92 - 96) + (96 -96) + (97- 96) + (97 -96) / 5

=0/5
mad = 0
brainliest is appreciated
Answer:
1.6
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
98+92+96+97+97=480
480/5 values=96 is the mean or average of the set of numbers
so we just find the absolute value of the data value minus the mean.
For the first one it would be |98-96|=2
then continue on and get a set of values
{2,4,0,1,1}
now find the average of that to get the mean absolute deviation
2+4+0+1+1=8
8/5 values

Working together, Daniel and Donnie can clean the llama pen in 45 minutes. On his own, Daniel can clean the pen in an hour. How long does it take Donnie to clean the llama pen on his own?
Answer:
It takes him 15 minutes.
Step-by-step explanation:
Donnie clean the llama pen in 180 minutes on his own.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Daniel and Donnie can clean the llama pen in 45 minutes.
And, On his own, Daniel can clean the pen in an hour.
Now,
Let time to clean the llama pen in on his own = x minutes.
Since, Daniel and Donnie can clean the llama pen in 45 minutes.
So, In 1 minute, Daniel and Donnie clean the pen = 1/45
And, In 1 minute Daniel to work = 1/60
Thus, We can formulate;
1/x + 1/60 = 1/45
Solve for x as;
(60 + x) / 60x = 1/45
60 + x = 60x / 45
60 + x = 4x/3
180 + 3x = 4x
180 = 4x - 3x
180 = x
Thus, Donnie clean the llama pen in 180 minutes on his own.

In your answers below, for the variable λ type the word lambda; for the derivative d/dx X(x) type X' ; for the double derivative d^2/dx^2 X(x) type X''; etc. Separate variables in the following partial differential equation for u(x,t): t^2uxx+x^2uxt−x^2ut=0
The final answer of the question which is the specific form of the solution u(x, t) = X(x)T(t)
What is the quadratic equation?
The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
To separate variables in the partial differential equation t²uxx + x²ux²t - x²zzut = 0, we assume that the solution can be written as a product of two functions, u(x, t) = X(x)T(t).
Let's begin by substituting this into the given equation:
t²(X''(x)T(t)) + x²(X(x)T'(t)) - x^2(X(x)T(t)) = 0
Now, we divide the equation by t²X(x)T(t) to separate the variables:
(X''(x) / X(x)) + (x^2 / t^2)(T'(t) / T(t)) - (x^2 / t^2) = 0
Next, we rearrange the terms:
(X''(x) / X(x)) + ((x² / t²)(T'(t) / T(t))) - (x² / t²) = 0
To satisfy this equation for all x and t, the left-hand side and the right-hand side must be equal to a constant value. Let's call this constant -λ^2:
(X''(x) / X(x)) + ((x² / t²)(T'(t) / T(t))) - (x² / t²) = -λ²
Now, we have two separate ordinary differential equations:
1. X''(x) / X(x) - x² / t² = -λ²
2. T'(t) / T(t) = λ²
Solving each equation separately will give us the general solutions for X(x) and T(t).
The general solution for u(x, t) can then be obtained by taking the product of X(x) and T(t):
u(x, t) = X(x)T(t)
The specific form of the solutions will depend on the boundary conditions or initial conditions given for the problem.
Hence, the final answer of the question which is the specific form of the solution u(x, t) = X(x)T(t)

Express the confidence interval (0.069.0.159) in the form of p-E
the confidence interval (0.069, 0.159) can be expressed as 0.114 ± 0.045
In a confidence interval, the lower bound represents the point estimate minus the margin of error, and the upper bound represents the point estimate plus the margin of error. In this case, the lower bound of the confidence interval is 0.069 and the upper bound is 0.159. To express it in the form of p ± E, we need to find the point estimate and the margin of error.
The point estimate, p, is the average or central value of the interval. In this case, it would be the midpoint between the lower and upper bounds:
p = (0.069 + 0.159) / 2 = 0.114
The margin of error, E, can be calculated by taking half the difference between the upper and lower bounds:
E = (0.159 - 0.069) / 2 = 0.045
Therefore, the confidence interval (0.069, 0.159) can be expressed as 0.114 ± 0.045.

Write a similarity statement comparing the three triangles in the diagram
P R S Q
Answer:
The answer is ΔJMK ≈ ΔMLK ≈ ΔJLM ⇒ answer (A)
Step-by-step explanation:
* Lets start with the equal angles i the three triangles
- In ΔJMK
∵ m∠JKM = 90°
∴ m∠KJM + m∠KMJ = 90 ⇒ (1)
- IN ΔMLK
∵ m∠MKL = 90°
∴ m∠KML + m∠KLM = 90° ⇒ (2)
∵ m∠KMJ + m∠KML = 90° ⇒ (3)
- From (1) , (2) , (3)
∴ m∠KJM = m∠KML
∴ m∠KMJ = m∠KLM
* Now lets check the condition of similarity in the 3 triangles
- At first ΔJMK and ΔMLK
- In triangles JMK , MLK
∵ m∠KJM = m∠KML
∵ m∠KMJ = m∠KLM
∵ m∠JKM = m∠MKL
∴ ΔJMK ≈ ΔMLK ⇒ (4)
- At second ΔJMK and ΔJLM
∵ m∠KJM = m∠MJL
∵ m∠KMJ = m∠MLJ
∵ m∠JKM = m∠JML
∴ ΔJMK ≈ ΔJLM ⇒ (5)
* If two triangles are similar to one triangle, then they are
similar to each other
- From (4) and(5)
∴ ΔJMK ≈ ΔMLK ≈ ΔJLM
