Answer:
172 cm^2
Step-by-step explanation:
Since it is a rectangular prism, you would have 6 sides, with two of them being the same. Each side is the values but multiplied by each other. So 7x2, 8x2, and 7x8. If you add them up it would be 14+16+56= 86, but that is only 3 sides, so you need to multiply 86 by 2, thus 172.

Janette went to Tire Mart and paid $122.57 per tire for 4 tires and a flat rate fee for installation for a total of $555.28 before taxes. Monique went to Fast Wheels and paid $136.71 per tire for 4 tires and a flat rate fee for installation for a total of $585.34 before taxes. The difference in the amount that they paid in installation charges is $
Answer:
$65
Step-by-step explanation:
Let's add up the flat rate and the cost of four tires:
flat rate + 4($122.57/tire) = $555.28
We are to solve for "flat rate." First, multiply out 4($122.57/tire), obtaining a tire cost of $490.28 total. Subtracting this tire cost from the $555.28 Janette paid the shop, we get "flat rate" = $555.28 - $490.28, or $65.
Thus, the installation charge ("flat rate") must have been $65.

express the following in factors; (n+1)!+n!
Answer:
n! (n + 2).
Step-by-step explanation:
(n + 1)! = (n + 1) * n * (n - 1) * (n - 2) .............. * 1.
n! = n * (n - 1) * (n - 2) .............. * 1
- so (n + 1)! = (n + 1) * n!
and (n + 1)! + n!
= n!( n + 1 + 1)
= n! (n + 2).
A salesperson makes a base salary of $2100 per month. Once he reaches $42,000 in total sales, he earns an additional 5% commission on the amount in sales over $42,000.
(1) Graph the function.
(2) If the salesperson had $80,000 in sales, how much was his salary?
(3) If the salesperson's total salary for a month was $4500, how much were his total sales for that month?
(4) Compute S(25000) and interpret what this means in the context of the problem.
Answer:
(1) Observe the attached image
(2) [tex]S = \$4,000[/tex]
(3) [tex]x = \$90,000[/tex]
(4) [tex]S = 2100[/tex]
Step-by-step explanation:
(1) Let's call S the salary for the month the seller wins.
Let's call x the amount of dollars reached by the sales of that month.
The seller earns a base salary of $ 2100 per month.
Then, if x> 42,000 he wins a commission of 5% on sales.
Then the equation modeling this situation is:
[tex]S =\left\{{{0.05(x-42,000)+2100\ if\ x>42,000} \atop{2,100\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ if\ 0\leq x\leq42,000}}\right.[/tex]
The graph of the function is shown in the attached image.
(2) If x = 80,000, then your salary was:
[tex]S = 0.05(80000-42000) +2100\\\\S = \$4,000[/tex]
(3) If S was 4500 and we want to find x then we equal S to 4500 and solve for x.
[tex]S = 4,500 = 0.05(x-42,000) + 2,100\\\\\frac{2,400}{0.05} = (x-42,000)\\\\x = \frac{2400}{0.05} +42,000\\\\x = \$90,000[/tex]
(4) S (25000) means that x equals 25000. Since x represents sales, this means that during the month, the seller only reached $ 25,000.
Then [tex]x <42000[/tex]
Therefore [tex]S = 2100[/tex].
With an example, how do I explain what the graph of a rational function looks like. Explain it in terms of it being a line and why the line is shaped the way it is on the graph.
Answer:
Hi,
These graphs looks like a smooth curve due to the asymptotes,or a straight line to which the graph of the function gets arbitrarily close.
Step-by-step explanation:
Rational functions are in the form of y= f(x) where f(x) is a rational expression. The graphs of rational functions are drawn by first finding the asymptotes and the intercepts. The graph follows a smooth curve that connects the points without crossing the vertical asymptotes. The line is shaped in that shape to satisfy the vertical line test.

The perimeter of a square is equal to four times the length of a side. Write the direct v variation equation that represents the situation. Y be the dependent variable and let X the independent variable
Answer: [tex]y=4x[/tex]
Step-by-step explanation:
A direct variation equation has the form:
[tex]y=kx[/tex]
Where k is a constant.
By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.
Then, knowing that y is the dependent value and x the independent value and the constant k=4, you can write the following direct variation equation that represents the situation.
[tex]y=4x[/tex]
Final answer:
The direct variation equation that represents the perimeter (Y) of a square in relation to its side length (X) is Y = 4X, where the constant of variation is 4.
Explanation:
The question asks us to write a direct variation equation where perimeter of a square is the dependent variable (Y) and the side length is the independent variable (X). For a square, the perimeter (P) is equal to four times the side length (s), hence we can write the direct variation equation as Y = 4X. This equation indicates that the perimeter of a square directly varies with its side length, with the constant of variation being 4.

Rolling two sixes in a row on a number cube. Dependent Or Independent?
Rolling a six on a die twice in a row is an example of independent events, as the outcome of one roll doesn't affect the outcome of the other, confirmed by applying the Multiplication Rule for independent events in probability theory.
Explanation:The question is asking whether rolling a six on a die twice in a row is considered a dependent or independent event. In probability theory, two events are considered independent if the occurrence of one does not affect the outcome of the other. In this case, rolling a die twice, the outcome of the first roll does not affect the outcome of the second roll. This is because each roll is a separate event and the die does not have a 'memory' of the previous roll.
Using the Multiplication Rule for independent events, we can confirm this. The Multiplication Rule states that the probability of two independent events happening together (A and B) is the product of their individual probabilities (P(A AND B) = P(A) * P(B)).
Applying this rule to our situation, the probability of rolling a six (A) and then rolling another six (B) is the product of the probabilities of each of these events happening on their own. This is (1/6)*(1/6) = 1/36. The result confirms that the two rolls are, indeed, independent events.

Find the area of the circle. Leave your answer in terms of pi.
Answer options:
16pi yd2
2pi yd2
4pi yd2
8pi yd2
Answer:
The correct answer is 4pi yd²
Step-by-step explanation:
The area of a circle is calculated using the formula A=πr², where A is area and r is radius of the circle. We obtain the radius of the circle by dividing the length of the diameter by 2, thus, the radius of the circle in the question is 4yd/2=2yd
substituting for the values we get, A= π×(2yd)²
A=4π yd²
ANSWER
[tex]A=4\pi {yd}^{2} [/tex]
EXPLANATION
The area of a circle is calculated using the formula,
[tex]A=\pi \: {r}^{2} [/tex]
The given circle has diameter which is 4 yards.
We divide the diameter into 2, to get the radius.
[tex]r = \frac{4}{2} = 2yd[/tex]
We substitute the radius to obtain,
[tex]A=\pi( {2}^{2} )[/tex]
This gives us,

sin(x) = 1/2 when x is 30°, 150°, 210°, or 330° (unit circle).
With those angles, the cos(x) is ±√3/2 and the tan(x) is ±√3/3.
Answer:
[tex]cos(x)=\pm \frac{\sqrt3}{2}[/tex]
[tex]\tan(x)= \pm \frac{1}{\sqrt3}[/tex]
Step-by-step explanation:
We are given the following information in the question:
[tex]\sin(x) = \displaystyle\frac{1}{2}[/tex]
We use the trigonometry identity:
[tex]\sin^2(x) + cos^2(x) =1[/tex]
Putting the value, we get,
[tex]\bigg(\displaystyle\frac{1}{2}\bigg)^2 + \cos^2(x) = 1\\\\\cos^2(x) = \frac{3}{4}\\\\\cos(x)=\pm \frac{\sqrt3}{2}[/tex]
Formula:
[tex]\tan(x) = \displaystyle\frac{sin(x)}{cox(x)}\\\\tan(x) = \frac{\pm \frac{1}{2}}{\frac{\sqrt3}{2}} = \pm \frac{1}{\sqrt3}[/tex]

the louvre pyramid is a metal and glass structure that serves the main entrance to the louvre Museum in Paris,France. The pyramid has a volume of 8820 cubic meters The base is a square woth sides that are 35 meters long
Answer:
h = 21.6 m
Step-by-step explanation:
*I'm assuming that you need the height. If not, let me know and I'll edit my answer...
The formula for volume of a pyramid is
V = (1/3)Bh where B is the area of the base, and h is the height
We are given V = 8820, and the base is a square with area of 35² = 1225, plug those in and find the height...
8820 = (1/3)(1225)h
26460 = 1225h (multiply both sides by 3 to get rid of the fraction)
26460/1225 = h (divide both sides by 1225 to isolate h)
21.6 = h

ill mark brainliest!What is the total surface area of this rectangular pyramid?
(square ft)
Answer:
S.A. = 225 ft²Step-by-step explanation:
We have a rectangle with dimensions 12 ft × 6 ft in the base of the pyramid and two pairs of triangles with a base of 12 ft and 6 ft and heights of 8 ft and 9.5 ft.
The area of a base:
[tex]A_B=(12)(6)=72\ ft^2[/tex]
The areas of the triangles:
[tex]A_1=\dfrac{(12)(8)}{2}=(6)(8)=48\ ft^2\\\\A_2=\dfrac{(6)(9.5)}{2}=(3)(9.5)=28.5\ ft^2[/tex]
The Surface Area:

Step-by-step explanation:
the expression we have is:

Because it is a product of two square roots, we can put it together in one:
[tex]\sqrt{(2x^3)(18x^5)}[/tex]
and we carry out the multiplication inside the square root
(to multiply the variable x we sum the exponents 3+5=8)
[tex]\sqrt{2*18x^{3+5}}\\\\=\sqrt{36x^8} \\[/tex]
and now we can take the square root of 36 which is 6.
and to take the square root if [tex]x^8[/tex] we divide the exponent by 2:

Step-by-step explanation:
Theorem :If from one external point, two tangents are drawn to a circle then they have equal tangent segments.
Two tangents DB and BE are drawn to a circle from one point i.e.B
So, Using theorem
DB=BE =10 cm
So, Using theorem
CF = CE = 15 cm
So, using theorem
AD =FA = 8 cm
Now AC = FA+CF = 8+15=23 cm
CB =BE+EC = 10+15=25 cm
AB = AD+DB=8+10=18 cm
Perimeter of triangle = Sum of all sides
=AB +CB+AC
= 18 + 25 +23

Hence the perimeter of ΔACB is 56 cm
What is the sum of the arithmetic series below 2+5+8+...+56
Answer:
551
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex]( first + last)
The number of terms is
[tex]a_{n}[/tex] = a + (n - 1)d ← d is the common difference, a is the first term
d = 5 - 2 = 8 - 5 = 3, hence
2 + 3(n - 1) = 56
2 + 3n - 3 = 56
3n - 1 = 56 ⇒ 3n = 57 ⇒ n = 19
[tex]S_{19}[/tex] = [tex]\frac{19}{2}[/tex] ( 2 + 56 ) = 19 × 29 = 551
The value of a stock increases at a rate of 1/2% per year. If the initial value of the stock $40 a share, when will the value of the stock be $50? Round your answer to the nearest tenth of a year
Answer:
After 45.7 years
Step-by-step explanation:
∵ r = 1/2% per year
∵ P0 = $40
∵ Pn = $50
∵ Pn = P0 ( 1 + r/100)^n-1
∵ P0 is initial value , Pn is the value after n years , is the rate
∴ 50 = 40 (1 + 0.5/100)^n-1
∴ 50/40 = (1.005)^n-1
∴ 1.25 = (1.005)^n-1 ⇒ insert ln in both sides
∴ ln(1.25) = (n-1)ln(1.005)
∴ n - 1 = ln(1.25)/ln(1.005)
∴ n = ln(1.25)/ln(1.005) + 1 = 45.7 years
