A family swimming pool membership costs $55 per month plus a one-time registration fee of $25. If a family has paid a total of $465, how many months have they been members?
Answers
total without registration fee = 465 - 25
= 440
55 = 1 month
440 = 1 ÷ 55 x 440
= 8 months
They have been members for 8 months.
The family has been members of the swimming pool for 8 months. This was calculated by setting up an equation with the formula for the total cost, C = 55m + 25, and solving for the number of months (m), with C set to the amount paid of $465.
To determine how many months a family has been members of a swimming pool with a membership cost of $55 per month plus a one-time registration fee of $25 and a total payment of $465, we need to set up an equation and solve for the number of months.
Let's denote the number of months as m. The total cost of the membership for m months is the monthly rate times the number of months plus the registration fee.
The equation representing the total cost (C) is:
C = 55m + 25
We know that the total cost is $465, so we substitute this value into the equation:
465 = 55m + 25
To solve for m, we first subtract 25 from both sides:
440 = 55m
Then, we divide both sides by 55 to find the number of months:
m = 440 / 55
m = 8
So, the family has been members for 8 months.

The minute hand of a clock is 4 inches long. how far does the tipof the minute hand move in 20 minnutes?
Answers
[tex]l=2\pi(4)(\frac{1}{3})[/tex]
The tip of the minute hand moves approximately (8/3)π inches in 20 minutes, using the circumference of the circular path it follows and the proportion of the path covered in that time.
Explanation:The student is asking about the distance traveled by the tip of the minute hand of a clock over a 20-minute period. To find the distance, we'll consider the movement of the minute hand as part of a circular path, which is described by the arc length of the circle segment.
The length of the minute hand, which is 4 inches, acts as the radius (r) of the circle. The minute hand completes one full rotation around the clock face in 60 minutes, so in 20 minutes, it covers one-third of a full rotation. We can find the arc length of the minute hand's path using the formula for the circumference of a circle (C = 2πr), multiplied by the fraction of the rotation:
Circumference: C = 2π(4 inches) = 8π inches
Arc Length for 20 minutes: (1/3) × 8π inches = (8/3)π inches
Therefore, the tip of the minute hand moves approximately (8/3)π inches in 20 minutes.

Answers
To find how much the temperature fell, we created an equation using the given temperatures at 5 P.M. and 10 P.M. We subtracted the temperature at 10 P.M. from the one at 5 P.M. and found the temperature fell by 25 degrees.
Explanation:The subject of this question is Mathematics and this question is for the Middle School grade level.
To solve this problem, we can create an equation using the given information about the temperature at two different times. At 5 P.M., the temperature (let's assume T1) is 20∘F. At 10 P.M., the temperature (let's assume T2) is -5∘F. Therefore, to find how much the temperature fell, we subtract the temperature at 10 P.M. from the temperature at 5 P.M., so the equation would be T1 - T2.
Substitute the temperatures into the equation: 20 - (-5) = 20 + 5 = 25.
Therefore, the temperature fell by 25 degrees.

The function L = 0.8T^2 models the relationship between L, the length in feet of a pendulum, and T, the period in seconds of the pendulum. Which value is closest to the period in seconds for a pendulum that is 30 ft long?
a 5.4s
b 4.9s
c 6.8s
d 6.1s
Answers
Given that L = 0.8T²
length of pendulum = 30ft
L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.
If possible, use the Law of Detachment to draw a conclusion from the two given statements. If not possible, write not possible. Statement 1: If x = 7, then 7x – 2 = 47. Statement 2: x = 7
Answers
Answer:
x=7
Step-by-step explanation:
The Law of Detachment can be used to conclude that 7x - 2 = 47.
Explanation:The Law of Detachment states that if a conditional statement is true and its hypothesis is true, then its conclusion must also be true. In this case, Statement 1 is a conditional statement: 'If x = 7, then 7x - 2 = 47.' Statement 2 tells us that x = 7. Since the hypothesis of Statement 1 is true (x = 7), we can apply the Law of Detachment to conclude that its conclusion must also be true. Therefore, we can validate Statement 1: '7x - 2 = 47.'

Basically we are going to have 2x times all of (x^2+3x-2)
And then we add on 2 times all of (x^2+3x-2)
Let's distribute through each piece
For the first part...
2x*(x^2+3x-2) = 2x*(x^2)+2x*(3x)+2x*(-2)
2x*(x^2+3x-2) = 2x^3+6x^2-4x
And then the second part..
2*(x^2+3x-2) = 2*(x^2)+2*(3x)+2*(-2)
2*(x^2+3x-2) = 2x^2+6x-4
-----------------------------------------
Putting this all together, we can say
(2x+2)*(x^2+3x-2) = 2x*(x^2+3x-2)+2*(x^2+3x-2)
(2x+2)*(x^2+3x-2) = 2x^3+6x^2-4x+2x^2+6x-4
(2x+2)*(x^2+3x-2) = 2x^3+8x^2+2x-4

How do you find vertical asymptotes?
Answers
Final answer:
To find vertical asymptotes of a function, factor the denominator, set each factor equal to zero, and solve for x.
Explanation:
To find vertical asymptotes of a function, we need to determine the values of x that make the function approach infinity or negative infinity. Vertical asymptotes occur when the function approaches these values but never reaches them.
To find the vertical asymptotes, follow these steps:
Factor the denominator of the function.
Set each factor equal to zero and solve for x.
The values of x obtained in step 2 are the vertical asymptotes.
For example, let's find the vertical asymptotes of the function f(x) = 1/x. The denominator is x, which is already factored. Setting x = 0, we find that x = 0 is the vertical asymptote.

Both trapezoids are similar. The area of the larger trapezoid is 61 ft2. Which is the best approximation for the area of the smaller trapezoid?
39 ft2
34 ft2
49 ft2
44 ft2
Answers
The best approximation for the area of the smaller trapezoid is 39 [tex]ft^2[/tex].
Since the trapezoids are similar, the ratio of their corresponding side lengths is constant. We know the base of the larger trapezoid is 30 ft and the smaller one is 24 ft. Therefore, the ratio of their bases is:
ratio of bases = [tex]\frac{30 ft}{24 ft}[/tex] = [tex]\frac{5}{4}[/tex]
The area of a trapezoid is given by:
Area = [tex]\frac{1}{2}[/tex] * base * height
For similar shapes, the ratio of their areas is proportional to the square of the ratio of their corresponding side lengths. In this case, the ratio of areas will be:
Ratio of areas = [tex](Ratio \ {of \ { bases)^2[/tex] = [tex]({\frac{5}{4} })^2[/tex] = [tex]\frac{25}{16}[/tex]
We know the area of the larger trapezoid is 61 [tex]ft^2[/tex]. Applying the ratio of areas:
Area of smaller trapezoid = (61 [tex]ft^2[/tex]) * [tex]\frac{16}{25}[/tex]
Area of smaller trapezoid ≈ 38.91 [tex]ft^2[/tex] ≈ 39[tex]ft^2[/tex]

Add 2x to both sides
-5y = 2x - 25
Divide both sides by -5
y = -2/5x + 5

The first term of the sequence is 2, so the first part of the definition is ...

Each term is 2 more than the previous one, so the rest of the definition is ...
a[n] = a[n-1] + 2

Comment on recursive rules
A recursive rule has two parts. The first part tells what the initial value of the sequence is. The second part relates the next term to the previous term or terms.
For arithmetic and geometric sequences, each term is related to the previous term by a constant. For an arithmetic sequence, each term is the last term plus the common difference. For a geometric sequence, each term is the last term multiplied by the common ratio.
For the arithmetic sequence 2, 4, 6, 8,.., the recursive rule can be written as: the first term a_1 is 2, and for all subsequent terms (n > 1), a_n equals the previous term a_(n-1) plus 2.
Explanation:The sequence given is an arithmetic sequence, where each term increases by 2. A recursive sequence is a sequence in which each term is defined based on its preceding terms. For the sequence 2, 4, 6, 8,... the recursive rule can be constructed as follows:
a_1 = 2
a_(n) = a_(n-1) + 2 for n > 1
In these rules, a_1 is the first term in the sequence, and a_(n) is the nth term of the sequence. a_(n-1) represents the term before the nth term in the sequence. This rule states that each term in the sequence is 2 more than the previous term.

Lets do the first one(7). Fist change 10x -2y = 3,which is in standard form to point slope form so you can see the slope.
10x - 2y = 3
-2y = -10x + 3
-2y/-2 = -10x / -2 + 3/-2
y = 5x - 3/2
The slope is the m in y = mx + b so our slope is 5x, well it wants you to find the equation of a line that passes through (0,1) that is parallel to the equation this (Parallel) mean has the same slope.The slope is 5. Now that we know the slope is 5 we can find the equation by using the point slope form of an equation of a line.
point slope form = y – y1 = m(x – x1)
Remember m = slope = 5. Now plugin our x and y cord from the point (0,1) and our slope of 5
y - y1 = m(x - x1)
y - 1 = 5(x - 0)
y - 1 = 5x - 0
y - 1+1 = 5x + 1
y= 5x + 1
So the point (0,1) passes through y = 5x + 1
Number 8 is already in slope intercept form so you don't have to do anything to find the slope. You can see that the slope is 7 so just plug your point into y - y1 = m(x - x1) and then put it into slope intercept form.
8)
Point = (5,8)
Slope = 7
y - y1 = m(x - x1)
y - 8 = 7(x - 5)
y = 7x - 27
So for number 8 the point (5,8) passes through y = 7x - 27
(9) For nine they want an equation that is perpendicular, which means to flip the slope. For instance, if you have a slope of 2/5 the perpendicular slope would be 5/2. For 9 we see that the slope is 2/5 so its perpendicular slope would be 5/2. Now just plug your point into the point slope form equation.
Point = (-4, 6)
Slope = 2/5
perpendicular slope = 5/2
y - 6 = 5/2(x - (-4))
y = 5/2 x + 16
So point (-4, 6) passes through y = 5/2 x + 16
(10) Point (4,1) passes through y = 7/5 x - 23/5

so is parallel to 10x-2y=3... now, let's solve that for "y", to put it in slope-intercept form

now, is parallel to [tex]\bf y=\stackrel{slope}{7}x-6[/tex] , now, that's already in slope-intercept form, so the slope we can see is just 7, so then.

9)
well, this function is also already in slope-intercept form, so we can tell the slope is 2/5.
now, the line we're looking for, is perpendicular to it, so it has a negative reciprocal slope, let's check
[tex]\bf \textit{perpendicular, negative-reciprocal slope for slope}\quad \cfrac{2}{5}\\\\ slope=\cfrac{2}{{{ 5}}}\qquad negative\implies -\cfrac{2}{{{ 5}}}\qquad reciprocal\implies - \cfrac{{{ 5}}}{2}[/tex]
so, we're looking for a line whose slope is -5/2 and passes (-4,6)
[tex]\bf \begin{array}{lllll} &x_1&y_1\\ % (a,b) &({{ -4}}\quad ,&{{ 6}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies -\cfrac{5}{2} \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-6=-\cfrac{5}{2}[x-(-4)] \\\\\\ y-6=-\cfrac{5}{2}(x+4)\implies y-6=-\cfrac{5}{2}x-10\implies \boxed{y=-\cfrac{5}{2}-4}[/tex]
10)
let's solve for "y" first
[tex]\bf 5x-7y=44\implies 5x-44=7y\implies \cfrac{5x-44}{7}=y \\\\\\ \stackrel{slope}{\cfrac{5}{7}}x-\cfrac{44}{7}=y[/tex]

A new business receives an invoice for merchandise on August 9. The terms of the sale are 12/10, n/30. If the manager elects to take the cash discount, what is the discount date?
Answers
Indication "12/10, n/30" (or "12/10 net 30") on an account represents a cash (sales) discount provided by the seller to the buyer for swift payment.
The term 12/10, n/30 is a classic credit term and means the following:
"10" indicates the number of days (from the invoice date) within which the buyer should pay the invoice in order to obtain the discount.
"n/30" states that if the buyer does not pay the (full) invoice amount within the 10 days to meet the requirements for the discount, then the net amount is due within 30 days after the sales invoice date.
The discount date begins at August 9 and the last day would be August 19.
The '12/10, n/30' term means a 12% discount is given if payment is made within 10 days of the invoice date, and the entire invoice must be paid within 30 days. As such, the discount date is August 19.
Explanation:The sale terms 12/10, and n/30 in the question denote a sale transaction where the seller is offering the buyer a 12% discount if they pay the invoice within 10 days of the invoice date. The 'n/30' part means that the rest of the invoice amount needs to be paid within 30 days. So, if the manager of the new business opts to take the cash discount, the discount date falls on August 19 (the invoice date - August 9 plus 10 days).

Item 22 the navy pier ferris wheel in chicago has a circumference that is 56% of the circumference of the first ferris wheel built in 1893. what was the radius of the first ferris wheel?
Answers
a) The radius of the navy pier wheel is 70 feet.
b) The radius of the first ferris wheel is 125 feet.
c) The speed of the wheel is 87.2 ft/sec
Given data:
The circumference of circle = 2πr
The area of the circle = πr²
a)
The circumference = 2πr
where π = 3.142
r = radius
Therefore, 2πr = 439.6
(2 * 3.142 * r) = 439.6
6.284r = 439.6
On simplifying the equation:
Radius = 439.6/6.284
Radius = 69.9
≈ 70 feet
b)
The Navy Pier Ferris Wheel in Chicago has a circumference that is 56% of the circumference of the first Ferris wheel.
So, 56% of f = 439.6
0.56f = 439.6
f = 439.6/0.56
f = 785
The circumference of the first wheel is 785 feet.
Now, 2πr = 785
r = 785/2π
r = 785/(2×3.142)
r = 785/6.284
r = 124.9
≈ 125ft
c)
The first ferris wheel took nine minutes to make a complete revolution.
So, the speed of wheel is determined as:
s = 785/9
s = 87.2 ft/sec
