In terms of x and y, Julia's withdrawal from her savings account was equal to y/4 + x/12.
What does algebraic expression mean?An expression obtained by performing a finite number of algebraic fundamental operations on symbols representing numbers.
What is an illustration of an algebraic expression?Algebraic expressions have at least one variable and one operation (addition, subtraction, multiplication, division). 2(x + 8y) is an example of an algebraic expression.Both Ang and Julia have savings balances of x and y dollars, respectively.
Ang = x dollars
Julia = y dollars
Ang offers Julia a third of his savings, which she then transfers to her own savings account.
Amount in Julia's account = (1/3)x + y
Julia then spends a quarter of the total into her savings account.
Amount of money Julia spent = 1/4 × [(1/3)x + y]
= (1/12)x + (1/4)y
= y/4 + x/12
Therefore, in terms of x and y, the amount Julia spent from her savings account is y/4 + x/12.

suppose that the weight, x, in pounds, of a 40-year-old man is a normal random variable with mean 147 and standard deviation 16. calculate p(120≤x≤153). round your answer to four decimal places.
0.6004 is standard deviation of equation .
Why is there a standard deviation?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.An individual collection of data is compared to the average of several other sets of data using the standard deviation. You can compute two different forms of standard deviation: When data are gathered from every person in a population or collection, it is the population standard deviation.=0.6004$P(120≤X≤153)=0.6004
The mean is μ=147, and the standard deviation is σ=16.
0.6462−0.0458=0.6004.
Thus, P(120≤X≤153)=0.6004.

Solve the following word problem using elimination. Set up a system of equations before solving in order to receive full credit.
The difference between two numbers is 4. The sum of the smaller number and three times the larger number is 36. What are the two numbers?
The two numbers are 10 and 6.
Now, let's take the larger number to be x and the smaller number to be y.
According to the question,
We have the following details:
The difference between two numbers = 4
So, we have the following expression:
(x-y) = 4 .... (1)
The sum of the smaller number and three times the larger number = 36
So, we have the following expression:
(3x+y) = 36 ....(2)
Now, we will use the elimination method to solve these equations. So, we will add equation 1 and 2.
(Please note that the left hand side is added to the left hand side and the right hand side numbers are added to the right hand side numbers.)
(x-y+3x+y) = (4+36)
4x = 40
x = 40/4 (4 is in multiplication on the left hand side. So, it is in the division on the right hand side.)
x = 10
Now, putting the value of x in equation 1,
(x-y) = 4 .... (1)
(10-y) = 4
-y = 4-10
-y = -6
y = 6
Hence, the larger number is 10 and the smaller number is 6.

Write the equation that is the translation of y = |x| left 9 units and up 11 units.
The translation of y = |x| left 9 units and up 11 units is y = |x+9|+11 .
The process of translating an existing graph or equation into a new graph is known as graph translation.
The alteration of algebraic equations is a typical form of algebraic challenge.A translation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of translation. The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).We know that for translation we have to change the x-coordinate and the y-coordinate by the amount that is stated in the translation.
Therefore from the graph we can see that the graph of y =|x| is represented by the blue line and the graph of translation y = |x+9|+11 is represented by the red line.

Tom sold t-shirts and hats at a festival. He made a $5 profit for each t-shirt he sold. He also made a profit of $40 from selling hats. If he made a total profit of $125, how many t-shirts did he sell?
The total number of t-shirts sold by Tom equals to 17 t-shirt.
What is a profit?Basically, a profit refers to the difference between the revenue that an entity has received from its outputs and the opportunity costs of its inputs.
We need to note that he made a total profit of $125. From here, we will proceed to use that data to solve other sections.
From the total profit of $125, he also made a profit of $40 from selling hats. That means that the T-shirt sales alone gives him a profit of $85 ($125 - $40).
Total quantity of t-shirt sold is computed as follows:
= Total profit from t-shirt / Profit per shirt
= $85 / $5

Order the following expressions from least to greatest.
Answer:
[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]
Step-by-step explanation:
The bars either side of an expression or a value are the absolute value symbol. "Absolute value" means how far a number is from zero. Therefore, the absolute value of a number is its positive numerical value.
The values of a, b and c are negative. All expressions except "a" are absolute values, and are therefore positive numerical values. Therefore, "a" is the least expression.
The simplest way to calculate each expression's numerical value is by assigning approximate numbers to each value, then carrying out each calculation.
From inspection of the graph:
a ≈ -3.8b ≈ -1.3c ≈ -0.7[tex]\begin{aligned} \implies |a - b| & \approx |-3.8 - (-1.3)|\\ & = |-2.5| \\ &= 2.5\end{aligned}[/tex]
[tex]\begin{aligned} \implies |b - c| &\approx |-1.3 - (-0.7)| \\ &= |-0.6| \\ &= 0.6\end{aligned}[/tex]
[tex]\implies a \approx -3.8[/tex]
[tex]\begin{aligned} \implies |a - c| &\approx |-3.8 - (-0.7)| \\ &= |-3.1| \\ &= 3.1\end{aligned}[/tex]
Therefore: -3.8 < 0.6 < 2.5 < 3.1
Hence, the expressions from least to greatest are:

The equation of the line in slope intercept form with slope 1/3 and passes through ( - 6, 0) is y = 1/3x + 2.
In mathematics, the slope or gradient of a line is a number that indicates the line's steepness as well as its X and Y directions. The letter "m" stands for slope. The ratio of the "vertical change" to the "horizontal change" between any two separate points on a line is used to compute the slope.
The equation of the line in point-slope form is expressed as:
y - y₁ = m( x - x₁ )
where m is the slope.
So, m = 1/3
( x₁, y₁ ) is the point on the line = ( - 6, 0)
Substituting the values,
y - 0 = 1/3( x + 6 )
y = 1/3( x + 6 )
y = 1/3x + 6/3
y = 1/3x + 2
Hence, the equation in slope-intercept form of the line is y = 1/3x + 2.

y = StartFraction plus-or-minus StartRoot x EndRoot Over 4 EndFraction minus one-fourth
The inverse of the given function, y = 16x² + 1 is: B. y = ±√(x - 1)/16
What is an inverse function?In Mathematics, an inverse function can be defined as a type of function that is obtained by reversing (undoing) the operation of a given function (f(x)).
Generally speaking, a given function (f(x)) and its inverse function has the following property f⁻¹(f(x)) = x.
In order to determine the inverse of the given function, we would interchange input value (x) and the output value (y) as follows:
y = 16x² + 1
x = 16y² + 1
Subtracting 1 from both sides, we have:
16y² + 1 - 1 = x - 1
16y² = x - 1
Dividing both sides by 16, we have:
y² = (x - 1)/16
Taking the square root of both sides, we have:

a 13-foot ladder is leaning against a wall. if we pull the ladder away from the wall at a rate of 6ft/s, how fast is the top of the ladder moving down the wall when the bottom of the ladder is 12ft from the wall?
Answer:
Below in bold.
Step-by-step explanation:
The relation between the height of the ladder and distance from the ground is given by Pythagoras Theorem:
h^2 = 13^2 - L^2
h = (169 - L^2)^1/2
Finding the derivative:
dh/dL = 1/2(169 - L^2)^-1/2 * -2L
= -L / (169 -L^2)^1/2
dL/dt = 6
So, dh/dt = dh/dL * dL/dt
= -6 * L/ (169 - L^2)^1/2
= -6 * 12 / (169 - 12^2)^1/2
= -72/5 ft /second
= -14.4 ft/second.
It's negative because the distance from the ground is decreasing.
