Answer:
The answer is $7.50.
Step-by-step explanation:
First you have to find the price of the souvenirs which were $2.25, just by doing each common price. Then you just do the answer you got divided by two.
The one ticket for this basketball game is $ 7.50, and one ticket for a souvenir is $2.25.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the price of the one ticket = $x
And the price of the one souvenir = $y
We have:
2x + y = 17.25 ....(1)
5x + 2y = 42.00 ....(2) (from the quetion)
From the equation (1):
y = 17.25 - 2x
Put the value of y in the equation (2), we get:
5x +2(17.25 -2x) = 42
5x + 34.5 - 4x = 42
x = 42 - 34.5
x = $ 7.50
and y = 17.25 - 2x ⇒ 17.25 - 2(7.5) ⇒ $2.25
Thus, the one ticket for this basketball game is $ 7.50, and one ticket for a souvenir is $2.25.

Find the surface area of the rectangular prism. A. 69.26 ft^2 B. 70.78 ft^2 C. 71.88 ft^2 D. 72.88 ft^2
Answer:
D
Step-by-step explanation:
The surface area of the rectangular prism is the sum of all the 6 faces.
There are 2 faces with length 3 ft and width 3.4 feet. Hence,Area = 2 (3*3.4) = 20.4
There are 2 faces with length 3 ft and width 4.1 ft. Hence,Area = 2 (3*4.1) = 24.6
There are 2 faces with length 3.4 ft and width 4.1 ft. Hence,Area = 2 (3.4*4.1) = 27.88
Thus, Surface Area = 20.4 + 24.6 + 27.88 = 72.88 ft ^2
Answer:
The correct answer option is D. 72.88 ft^2.
Step-by-step explanation:
We are given a diagram of a rectangular prism with width 3 ft, length 3.4 ft and height 4.1 ft and we are to find its surface area.
We know that the surface area of a rectangular prism is given by:
[tex]2(wl \times hl \times hw)[/tex]
So substituting the given values in the above formula to get:
Surface area of rectangular prism = [tex]2[(3 \times 3.4) + (4.1 \times 3.4) + (4.1 \times 3)][/tex] = 72.88 ft^2

Find the difference 5x/x^2-x-6 (-) 4/x^2+4x+4
The difference is [tex]\( \frac{5x^2 + 6x + 12}{(x-3)(x+2)(x+2)} \)[/tex].
To subtract the two rational expressions [tex]\( \frac{5x}{x^2-x-6} \) and \( \frac{4}{x^2+4x+4} \)[/tex], we need to find a common denominator.
First, factor the denominators:
1. x²-x-6 = (x-3)(x+2)
2. x²+4x+4 = (x+2)²
The common denominator will be (x-3)(x+2)(x+2).
Now, rewrite the expressions with the common denominator:
1. [tex]\( \frac{5x}{(x-3)(x+2)} \)[/tex]
2. [tex]\( \frac{4}{(x+2)^2} \)[/tex]
To subtract, the numerators remain the same, so the expression becomes:
[tex]\[ \frac{5x}{(x-3)(x+2)} - \frac{4}{(x+2)^2} \][/tex]
To combine the fractions, we need to rewrite the first fraction with the common denominator:
[tex]\[ \frac{5x(x+2)}{(x-3)(x+2)(x+2)} - \frac{4(x-3)}{(x-3)(x+2)(x+2)} \][/tex]
Now, we can subtract the fractions:
[tex]\[ \frac{5x(x+2) - 4(x-3)}{(x-3)(x+2)(x+2)} \\\[ = \frac{5x^2 + 10x - 4x + 12}{(x-3)(x+2)(x+2)} \\\[ = \frac{5x^2 + 6x + 12}{(x-3)(x+2)(x+2)} \][/tex]
So, the difference is [tex]\( \frac{5x^2 + 6x + 12}{(x-3)(x+2)(x+2)} \)[/tex].
To find the difference between the two rational expressions, we first need to factorize the denominators and simplify where possible. Let's break it down step by step:
1. Factorize the denominators:
[tex]\(x^2 - x - 6 = (x - 3)(x + 2)\) \(x^2 + 4x + 4 = (x + 2)^2\)[/tex]
2. We rewrite the expressions with common denominators:
[tex]\(\frac{5x}{(x - 3)(x + 2)} - \frac{4}{(x + 2)^2}\)[/tex]
3. To simplify these, we need a common denominator, The least common denominator is [tex]\((x - 3)(x + 2)^2\).[/tex], so to get it, we multiply (x + 2) with Expression 1 and (x - 3) with Expression 2 on both numerator and denominator. We get:
[tex]\(\frac{5x(x + 2)}{(x - 3)(x + 2)^2} - \frac{4(x - 3)}{(x - 3)(x + 2)^2}\)[/tex]
4. We combine the fractions:
[tex]\(\frac{5x(x + 2) - 4(x - 3)}{(x - 3)(x + 2)^2}\)[/tex]
[tex]\(= \frac{5x^2 + 10x - 4x + 12}{(x - 3)(x + 2)^2}\) \(= \frac{5x^2 + 6x + 12}{(x - 3)(x + 2)^2}\)[/tex]
So, the difference between the two rational expressions is [tex]\(\frac{5x^2 + 6x + 12}{(x - 3)(x + 2)^2}\).[/tex]

Brooke paints the outsides of the square walls and triangular ceilings of her treehouse. What area does she paint?
Answer:
Broke paints [tex]216\ ft^{2}[/tex]
Step-by-step explanation:
we know that
The area of the outsides of the square walls and triangular ceilings of her tree house is equal to the area of four squares and four triangles
so
[tex]A=4[(6)^{2} +\frac{1}{2}(6)(6)]\\ \\A=4[36+18]\\ \\A=216\ ft^{2}[/tex]
The surface area of the square walls and triangular ceiling she painted is 216 ft²
How to find the surface area of the painted region?
The surface area of the painted region can be found as follows:
area of the square = l²
where
l = side lengthTherefore,
l = 6 ft
area of the square = 6² = 36 ft²
Area of the triangular region = 1 / 2 bh
where
b = baseh = heightTherefore,
area of the triangular region = 1 / 2 × 6 × 6 = 36 / 2 = 18 ft²
Therefore,
area of the painted region = 18(4) + 36(4) = 144 + 72 = 216 ft²

The losing candidate in a mayoral election received 10,200 votes, which represented 30% of all votes cast in the election.
A. Dorian claims that the total number of votes cast in the mayoral election was 3,060. Dorian made a mistake in his calculations. Why is his claim not reasonable? Explain your answer.
B. Find the total number of votes cast in the mayoral election. Explain how you found your answer.
well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.
B)
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x[/tex]
A)
Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.
Final answer:
Dorian's claim is incorrect because dividing 10,200 votes by 30% (or 0.30) gives 34,000 votes, which is the correct total number of votes cast in the mayoral election. Therefore, the calculation shows that the total votes are much higher than Dorian's claim of 3,060 votes.
Explanation:
A. Dorian's claim that the total number of votes cast in the mayoral election was 3,060 is not reasonable because if the losing candidate received 10,200 votes which represented 30%, then the total votes should be much higher than 3,060. To find the total, you would divide the number of votes the candidate received by the percentage they represent.
B. To find the total number of votes cast in the mayoral election, you would set up the equation 10,200 = 0.30 * Total Votes. Dividing 10,200 by 0.30 gives the total number of votes cast, which is 34,000.
Equation: Total Votes = 10,200 votes / 0.30 = 34,000 votes

Find the surface area of the regular hexagonal pyramid. Round your answer to the nearest hundredth. A. 69.18 m^2 B. 79.18 m^2 C. 89.18 m^2 D. 99.18 m^2
Answer: OPTION B
Step-by-step explanation:
Use the following formula:
[tex]SA=\frac{pl}{2}+B[/tex]
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
The perimeter is:
[tex]p=6*s=6*3m=18m[/tex]
Where s is the lenght of a side.
The slant height is given:
[tex]l=6,2m[/tex]
The area of the base is:
[tex]B=\frac{3\sqrt{3}s^2}{2}=\frac{3\sqrt{3}(3m)^2}{2}=23.382m^2[/tex]
Where s is the length of a side.
Substitute values. Then, the result is:
[tex]SA=\frac{(18m)(6.2m)}{2}+23.382m^2=79.18m^2[/tex]
Answer:
The correct answer option is B. 79.18 m^2.
Step-by-step explanation:
We are given a diagram of a regular hexagonal pyramid with height 5.6 m, slant height 6.2 m and base edge length 3m.
We know that the surface area of a regular hexagonal pyramid is given by:
[tex]\frac{PI}{2} +B[/tex]
where P = perimeter of the base, I = slant height and B = base area.
Perimeter of base = [tex]3 \times 6[/tex] = 18 m^2
Base area (area of hexagon) = [tex]\frac{3\sqrt{3} }{2} a^2[/tex] = [tex]\frac{3\sqrt{3} }{2} 3^2[/tex] = 23.38 m^2
Surface area of hexagonal pyramid = [tex]\frac{18 \times 6.2}{2} +23.38[/tex] = 79.18 m^2
The measures of the three angles of a triangle are given by 3x + 1, 2x − 3, and 9x. What is the measure of the smallest angle?
Answer:
23°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
3x + 1 +2x - 3 + 9x = 180 ( simplify left side )
14x - 2 = 180 ( add 2 to both sides )
14x = 182 ( divide both sides by 14 )
x = 13
The 3 angles are
3x + 1 = (3 × 13) + 1 = 39 + 1 = 40°
2x - 3 = (2 × 13) - 3 = 26 - 3 = 23° ← smallest angle
9x = 9 × 13 = 117°
help with 11a please?? (25 points)
Answer:
so A = 45degrees because tan^-1(1) = 45 and c = 30 because the half triangle is a 30-60-90 triangle so d = 105
Since its a 30-60-90 triangle and you know that one of the sides is 6, you can now infer that the rest of the sides are 8, and 10.
Also using the 6 side you can use a 3-4-5 triangle by dividing 6 by 4 wich equals 1.5 then multiply that by 3 to get the other sides by using Pythagorean therom. so the sides are 10, 7.5 and 12.5 witch gives you the bas and since area = 1/2bh area= 1/2(12.5 times 6)= 37.5
A = 37.5
The first morning Courtney walked on a beach for 20 minutes . She finished 30 minutes before high tide at what time did Courtney start her walk
Martha walked for 0.67 hours.
Here's how we can calculate it:
Total time spent hiking:
12:30 AM - 11:30 PM = 1 hour (since 12:30 AM is midnight and the same as 00:30 AM)
Convert hours to minutes: 1 hour * 60 minutes/hour = 60 minutes
Time spent running:
Subtract the walking time from the total time: 60 minutes - 20 minutes = 40 minutes
Convert running time to hours:
Divide minutes by minutes per hour: 40 minutes / 60 minutes/hour = 0.67 hours
Therefore, Martha walked for 0.67 hours.

Complete the square and write the equation in standard form. Then give the center and radius of the circle. 10x2 + 10y2 = 100
2 + y2 = 10 (0, 0), r = 10
x2 + y2 = 100 (0, 0), r = 10
x2 + y2 = 10 (0, 0),
r = 10‾‾‾√
(x - 10)2 +(y - 10)2 = 10 (10, 10),
r = 10‾‾‾√
Answer:
Center: (0,0)
Radius: [tex]r=\sqrt{10}[/tex]
Step-by-step explanation:
The given circle has equation
[tex]10x^2+10y^2=100[/tex]
In order to complete the square, we must make sure the coefficient of the quadratic terms are unity.
We divide through by 10 to obtain;
[tex]x^2+y^2=10[/tex]
The coefficient of the linear terms of both variables are zero.
Therefore the equation can be rewritten as;
[tex](x-0)^2+(y-0)^2=10[/tex]
Comparing to [tex](x-h)^2+(y-k)^2=r^2[/tex]
We have (h,k)=(0,0) to the center of the circle and [tex]r=\sqrt{10}[/tex] to be the radius of the circle.
Answer:
Equation: x² + y² = 10
center = (0, 0)
radius = √10
Step-by-step explanation:
The general equation of a circle is ;
(x - a)² + (y - b)² = r²
Where (a, b) is the coordinate of the center of the circle, and r is its radius.
Where the center is (0,0), the equation becomes,
x² + y² = r²
In our case we have;
10x² + 10y² = 100
dividing both side by ten,
x² + y² = 10
∴ center = (0, 0)
radius = √10
Select the domain and range of F. F = {(x, y ) | x + y = 10}. Domain: {10} Range: {10} Set F is not a function and does not contain a domain or range Domain: All Real Numbers Range: All Real Numbers
The equation x + y = 10 represents a linear relationship that spans all real numbers in both x and y directions. Thus, the domain and the range for this function are both all real numbers.
Explanation:The equation for the set F is x + y = 10, which is a straight line on a graph. This line extends infinitely in both directions, meaning that there is no restriction on the possible values of x (the domain) and y (the range). Therefore, the correct answer for both domain and range would be 'All Real Numbers'.
To visualize this, imagine you plug in any number for x and solve the equation for y. Similarly, you can do the same, guessing a y-value and solving for x. No matter the number chosen, there will always be a corresponding number on the other side, whether positive, negative, or zero.
Remember that a domain is the set of all inputs (or 'x' values) that a function can accept, and a range is the set of all possible outputs (or 'y' values) that the function can produce. In this example, the function can handle and generate all real numbers, so its domain and range are all real numbers.

A jewelry store is having a going-out-of-business sale. All merchandise is marked 40% off the regular price. The regular price of a watch is $59.95 what is the amount of the discount and the sale price
Answer:
$35.97
Step-by-step explanation:
the regular price is 59.95
40% discount so
let's say the price now is x and i am gonna do fractions
x/59.95 = 40%/100
100 x X = 100x
59.95 x 40 = 2398
i divide 2398 by 100 which equal 23.98
40% is 23.98 and then i do 59.95 - 23.96 = 35.97
DONE!
The discount amount on the watch is $23.98 and the sale price after applying the 40% discount off the regular price of $59.95 is $35.97.
When a jewelry store is having a going-out-of-business sale, and all merchandise is marked 40% off the regular price, we can calculate the amount of the discount and the sale price using percentage formulas. For example, if a watch has a regular price of $59.95, we multiply this price by 40% (or 0.40) to find the discount amount.
To find the discount amount: $59.95 times 0.40 = $23.98
Next, to find the sale price, we subtract the discount amount from the regular price.
To find the sale price: $59.95 - $23.98 = $35.97
Therefore, the discount amount is $23.98, and the sale price of the watch is $35.97.
What is the degree of the function f(x)= x(x+1)2 (2x-3)(x+2)2
