Answer:
110
Step-by-step explanation:
Sally takes $110 from her bank account if she spent $54.00 for a round-trip ticket.
What are expenses?It is defined as the money spends on the utility, the amount of money is required to buy something, in other words, it is the outflow of money from the sole earner's income or the money incurred by any organization.
We have:
Sally took money from her bank account to go out of town for an audition.
The expeses = (7.90 + 15.10) ÷ (1 - 1/2) = $46
Total money = 54 + 46
Total money = $110
Thus, Sally takes $110 from her bank account if she spent $54.00 on a round-trip ticket.

A distance travaled by train in three hours with a constant speed of r miles per hour
The distance travelled by the train with constant speed of r miles will be 3r.
What is Speed?The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities. One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session. The pace at which an object's location changes in any direction. When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed. When an object travels a different distance at regular intervals, it is said to have variable speed.We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r

Thank you!
Using the given linear function of best-fit, the most likely approximate height of the plant after 8 weeks would be of 7.4 centimeters.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The line of best-fit goes through points (0,1) and (5,5). Point (0,1) means that the y-intercept is of b = 1. The slope is given as follows:
m = (5 - 1)/(5 - 0) = 4/5 = 0.8.
Hence the equation that gives the approximate height after x weeks is:
y = 0.8x + 1.
After 8 weeks, the expected height is:
y = 0.8 x 8 + 1 = 6.4 + 1 = 7.4 centimeters.

Find the equation of the line that passes through the following points: (a, b) and (a, b +1 )
Answer:
The equation for the line which passes through the points given as (a, b) and (a, b+1), is x=a, which represents a vertical line.
Step-by-step explanation:
It is given that a line passes through the points whose coordinates are (a, b) and (a, b+1).
It is asked to find the linear equation which passes through the given points.
To do so, first determine the slope of the given line using the coordinates and the formula for the slope. Accordingly, proceed to find the equation of the given line.
Step 1 of 2
Determine the slope of the line.
The points through which the line passes are given as (a, b) and (a, b+1). Next, the formula for the slope is given as,
[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
Substitute b+1&b for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and a&a for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows,
[tex]m=\frac{b+1-b}{a-a}$\\ $m=\frac{1}{0}$[/tex]
b+1. So the equation of the line cannot be found using the general point-slope form equation.
Step 2 of 2
Write the equation of the line.
So, by definition, the line that passes through the given points is a vertical line. Now, as its x- coordinate is a, so the equation of the line is given as x=a.

What is the measure of RCD?
Find length CD first, which is the hypotenuse of the triangle.
PD = opposite
Opposite & hypotenuse = SOH or sin
Sin(27) = 15/H
x h, then ÷ sin(27)
H = 15/sin(27)
H = 33.04....
Move to triangle CDR:
15 is length opposite the angle we're after.
So far, we've got the hypotenuse (which we just found to be 33.04....) & the opposite of our triangle
Hypotenuse & opposite = SOH
Sin(x) = 15/33.04... but, to find the angle we do inverse of sin
sin-1(15/33.04...) = x
x = 27
(33.04... means I used the full numbers displayed on my calculator)
Thus, RCD is 27 degrees

Now it is given that number of candidates, n = 15
and number of position, r = 3
Hence number of ways positions can be filled-
[tex]P(n,r) =\frac{15!}{(15-3)!}[/tex]
⇒ [tex]P(15,3) =\frac{15!}{12!}[/tex]
⇒ P(15,3) = (15 × 14 × 13)12!/12!
⇒ P(15,3) = (15 × 14 × 13)
⇒ P(15,3) = 2730
∴ Number of ways in which 3 positions can be filled are 2730.

Solve the equation f(x)=x3+2x2+4x+8 given that one of its roots is x=−2.
Okay, first you need to understand that function of x, (or f(x)) is y.
We now plug in x.
f(-2) or y=-2(3)+(2•2)+4(-2)+8
f(-2)=-6+4+-8+8
f(-2)=-2
When x=-2, y=-2. Lets plug it back in to see if its true.
-2=-2(3) + (2x2) + (4(-2)) + 8
-2 = -6 + 4 + -8 + 8
-2 = -2.

The system of linear inequalities which satisfy the region R are:
y < x - 3.y ≤ -2x + 5.y ≥ x.How to find the inequalities?Mathematically, the standard equation of a straight line is given by y = mx + b.
In order to determine the system of linear inequalities that satisfy the region R, we would identify the points through which the lines passes through.
For the broken line, we have:
y-intercept = 3.
x-intercept = -3.
Points (x, y) = (0, 3) and (-3, 0).
Since the line is broken (not equal to), the inequality is given by:
y < x - 3.
For the other line, we have:
y-intercept = 5.
x-intercept = -5/2.
Points (x, y) = (0, 5) and (-5/2, 0).
(x/-5/2) + y/5 ≤ 1
-2x + y ≤ 5
y ≤ -2x + 5
For the line passing through the origin, we have:
y - x ≥ 0
y ≥ x.

The dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.
Given that the length of the previous deck = 15 feet
The width of the previous deck = 12 feet
Since the new deck will add 5 feet to the length and 4 feet to the width,
The length of the new deck = 15 + 5 = 20 feet
The width of the new deck = 12 + 4 = 16 feet
Also given that a drawing of the new deck uses a scale of 1 inch = 2.5 feet.
So, The length of the deck in the drawing = 20/2.5 inches = 8 inches
The width of the deck in the drawing = 16/2.5 inches = 6.4 inches

The quartic formula has up to four various solutions including real and imaginary numbers. Read on for more explanation.

First we restate the above equation:

Next we remove square roots
[tex]x^{4}[/tex] - 6x³ + 9x² = x - 2
Add two to both sides

Complete the point-slope equation of the line through-8,-8) and (7, 9)
Answer:
[tex]y = \frac{17}{15}x + \frac{16}{15}[/tex]
Step-by-step explanation:
So the slope-intercept form is given as: y=mx+b where m is the slope and b is the y-intercept (since if you plug in 0 as x, mx will be 0 leaving only b). You can calculate the slope with the slope formula: [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] which is essentially [tex]\frac{rise}{run}[/tex]. So for this example (-8, -8) will be ([tex]x_1, y_1[/tex]) and (7, 9) will be ([tex]x_2, y_2[/tex]).
Plug values into equation:
[tex]\frac{9 - (-8)}{7 - (-8)}[/tex]
cancel out negatives
[tex]\frac{9+8}{7+8}\\[/tex]
Simplify
[tex]\frac{17}{15}[/tex]
The fraction is in the most simplified form unless you want to have a mixed fraction, otherwise you can't do anything else to the fraction.
so now we have the slope we have one part of the equation: [tex]y=\frac{17}{15}x + b[/tex], but now we need to solve for b. This can be done by using either of the points and plugging in x and y, but for this example I'll use (7, 9).
Plug in (7, 9) as (x, y)
[tex]9 = \frac{17}{15}(7) + b[/tex]
Multiply
[tex]9 = \frac{119}{15}+b[/tex]
Subtract
[tex]9-\frac{119}{15}=b[/tex]

Step-by-step explanation:
In the first sequence, notice that each term increases by a factor of 8 (multiplied by 8 each time). Therefore, the fourth term would be 64*8 = 512, so the fifth term is 512*8 = 4096.
In the second sequence, each term decreases by a factor of 2 (divided by 2 each time). The fourth term would be 500/2 = 250, so the fifth term is 250/2 = 125.
