Answer:
The length of the shorter piece is 13 inches
Step-by-step explanation:
Let's represent the longer piece of pipe with the variable L and the shorter piece of pipe with variable S.
Since the pipe is going to be the length of L and S together, we can make this equation:
L+S=52
Also we know that the longer piece is three times the shorter piece or
L=3S
Substitute the second equation into the first equation.
L+S=52
3S+S=52
4S=52
Divide both sides by 4
4S/4=52/4
S=13 inches
The length of the shorter piece is 13 inches....
To find the length of longer piece, put the value S=13 in L=3S
L=3S
L=3(13)
L=39 inches
The length of the longer piece is 39 inches....
What is the factored form of the expression over the complex
numbers?
16x2 + 9y2
Answer:
(4x -3yi) (4x+3yi)
Step-by-step explanation:
We have a^2 + b^2
Over the complex number, this is equal to
(a-bi) (a+bi)
(4x -3yi) (4x+3yi)
Answer:
(4x -3yi) (4x+3yi)
Step-by-step explanation:
The expression 16x^2 + 9y^2 is a sum of squares, and it can be factored over the complex numbers using the difference of squares formula:
a^2 + b^2 = (a + bi)(a - bi)
In your expression:
a = 4x
b = 3y
So, applying the difference of squares formula:
16x^2 + 9y^2 = (4x + 3yi)(4x - 3yi)
This is the factored form of the expression 16x^2 + 9y^2 over the complex numbers.

I don't understand how to prove that this is an isosceles triangle.
Check the picture below.
so, two tangents to the same circle, whenever they meet outside the circle, they'll be congruent, namely, AB = AX and CB = CY and DX = DY.
well, we know AB = BC, and we know that AB = AX and CB = CY, therefore
AB = BC = AX = CY = 10.
an isosceles needs twin sides, well, we know DX = DY, and we know that AX = 10 then the triangle's side AD = AX + DX = 10 + DX.
the triangle's side of CD = CY + DY = 10 + DY.
but but but, we know DX and DY are tangents to a common circle meeting outside, so they're equal, so whatever length DX and DY are, is the same, so
10 + DY = 10 + DX
meaning the triangle's sides AX = CD, and for an isosceles, is all you need, twin sides.

The diameter of a circle is given by the two points (5,-2) and (1,-2). What is the length of the diameter? What is the radius of the circle? What’s the equation of the circle?
Answer:
Diameter: 4
Radius: 2
Equation: ( x-3 ) + ( y + 2) = 4
Final answer:
The length of the diameter is 4 units, the radius of the circle is 2 units, and the equation of the circle, with its center at (3,-2), is (x - 3)² + (y + 2)² = 4.
Explanation:
The diameter of a circle is the distance between two points on the circumference of the circle which pass through the center of the circle. The two points given are (5,-2) and (1,-2), which both lie on a horizontal line since their y-coordinates are the same. To find the length of the diameter, you calculate the distance between these two points using the distance formula:
d = √((x2 - x1)² + (y2 - y1)²)
For these points, it becomes:
d = √((1 - 5)² + (-2 - (-2))²) = √((-4)² + (0)²) = √(16) = 4
Therefore, the length of the diameter of the circle is 4 units.
To find the radius of the circle, which is half the diameter, divide the diameter by 2:
r = d / 2 = 4 / 2 = 2 units
The equation of a circle in the standard form is (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. Given that the center is the midpoint between (5,-2) and (1,-2), which is (3,-2), the equation of the circle with a radius of 2 would be:
(x - 3)² + (y + 2)² = 2²
(x - 3)² + (y + 2)² = 4

Find the area of the trapezoid
A. 150 ft^2
B. 300 ft^2
C. 45 ft^2
D. 75 ft^2
Answer: 75
Step-by-step explanation:
The area formula for a trapzoid is area= 1/2 (a+b) h
In this equasion, the substitution would be area=1/2 (10+15) 6
Following PEMDAS, enter the numbers within the parenthases (10+15)
Divide the 25 in half, then multiply by 6. This comes out to 75.
For this case we have that by definition, the area of a trapezoid is given by:
[tex]A = \frac {1} {2} (B + b) * h[/tex]
Where:
B: It is the major base
b: It is the minor base
h: It's the height
According to the figure we have the following data:
[tex]B = 15ft\\b = 10ft\\h = 6ft[/tex]
Substituting in the formula:
[tex]A = \frac {1} {2} (15 + 10) * 6\\A = \frac {1} {2} (25) * 6\\A = \frac {1} {2} 150\\A = 75[/tex]

A shipping box in the shape of a cube has an edge length of 8 inches. It can hold 8 mugs with no extra space between them. If the dimensions of the shipping box are all doubled, what is the maximum number of mugs that the larger box can hold? 16 24 48 64
Answer:
64
Step-by-step explanation:
Volume of a cube is:
V = s³
When s = 8 in:
V = (8 in)³ = 512 in³
When s is doubled (s = 16 in):
V = (16 in)³ = 4096 in³
Now we can write a proportion:
8 mugs / 512 in³ = x mugs / 4096 in³
x = 64
The maximum number of mugs that the larger box can hold is:
64
Step-by-step explanation:The edge length of box is: 8 inches.
This means that the volume of box is: 8×8×8=512 cubic inches.
Also, the number of mugs a box of edge length 8 in. can hold is: 8
Hence, volume of 1 mug= Volume of box/Number of mugs
Volume of 1 mug= 512/8=64 cubic inches
Now, if the dimension of the box is doubled.
This means that the Volume of new box= 8×Volume of old box
Volume of new box=8×512=4096 cubic inches
Let n be the number of mugs that the new box can hold.
Volume of new box=n×Volume of 1 mug
⇒ 4096=n×64
⇒ n=4096/64
⇒ n=64
Hence, the answer is:
64

Step-by-step explanation:
1702/152: 11.1973684211
about 11 in each box
11 x 152 = 1672
1702 - 1672 = 30

The perimeter of a rectangular field is 26 yards. The length is 4 more yards than twice the width. Find the length and width of the field.
A. Length = 8 yards; Width = 4 yards
B. Length = 10 yards; Width = 3 yards
C. Length = 13 yards; Width = 9 yards
D. Length = 8.5 yards; Width = 4.5 yards
The formula for perimeter is P = 2length + 2width (P = 2L + 2W)
You know that the length is 4 more yards then twice the width. In equation form this would be:
length = 4 + 2w
Plug what you know into the perimeter formula:
26 = 2(4 + 2w) + 2w
First you must distribute the 2 to the numbers inside the parentheses, which would be 4 and 2w...
26 = (2 * 4) + (2 * 2w) + 2w
26 = 8 + 4w + 2w
Now you must combine like terms. This means that first numbers with the same variables (w) must be combined...
26 = 8 + 4w + 2w
4w + 2w = 6w
26 = 8 + 6w
Now bring 8 to the left side by subtracting 8 to both sides (what you do on one side you must do to the other). Since 8 is being added on the right side, subtraction (the opposite of addition) will cancel it out (make it zero) from the right side and bring it over to the left side.
26 - 8 = 8 - 8 + 6w
18 = 0 + 6w
18 = 6w
To isolate w divide 6 to both sides
18 / 6 = 6w / 6
w = 3
We know that the width is 3 ft
Now you must find the length. To do this plug 3 where you see w in the equation:
length = 4 + 2w
l = 4 + 2(3)
l = 4 + 6
l = 10
We know that length is 10 ft

Match the key aspect of a functions graph with its meaning.
The key aspect of a function's graph in Mathematics is its ability to visually illustrate relationships, patterns, and comparisons. Different types of graphs, like line, bar, and pie, provide different ways to interpret the data. Understanding these graphs helps in mathematical analysis and solving problems.
Explanation:The question involves analyzing functions' graphs and matching them with their meanings. In Mathematics, a function's graph can represent different types of information based on its structure. For example, a line graph signifies a linear relationship between two variables denoted on the horizontal and vertical axis. The height of the curve at any point on the graph represents the value of the function at that point.
Three distinct types of graphs are the line, bar, and pie graph. A line graph shows the relationship between two variables with one variable being represented on the horizontal axis and the other on the vertical axis. A bar graph utilises the height of the bars to signify a relationship, with each bar representing a distinct entity like a group of people or a country. A pie graph is used to show how something is distributed, with each slice representing the corresponding percentage of the whole.
Deciphering this information from a graph includes recognizing patterns, comparisons, and trends, providing an intuitive sense of relationships in the data.

Here are the matches: f(x) > 0: Intervals of the domain where the graph is above the x-axis. f(x) < 0: Intervals of the domain where the graph is below the x-axis. Y-intercept: Location on the graph where the output is zero. X-intercept: Location on the graph where the input is zero.
In a function f(x), when f(x) > 0, it indicates the intervals on the domain where the function's values are positive, corresponding to regions above the x-axis. Conversely, when f(x) < 0, it denotes intervals where the function's values are negative, representing areas below the x-axis.
The y-intercept is the point where the graph intersects the y-axis, highlighting where the output (function value) is zero. On the other hand, the x-intercept is where the graph crosses the x-axis, signifying the point where the input (x-value) is zero, resulting in a zero output. These aspects provide valuable insights into a function's behavior and characteristics.

Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
x + 3y = 10
y = x + 2
Answer:
x = 1
y = 3
Step-by-step explanation:
We can solve this problem by inputting the second equation into the first equation by replacing the y variable with the second equation.
x + 3y = 10
y = x + 2
x + 3(x + 2) = 10
Now, distribute three with x and 2
3 * x = 3x
3 * 2 - 6
x + 3x + 6 = 10
4x + 6 = 10
Subtract 6 from both sides
4x = 4
So, x = 1
Solve for y by replacing x in the second equation with 1.
y = 1 + 2
y = 3
The solution to the system of equations is x = 1 and y = 3.
To solve the system of equations using the substitution method, we can start by substituting the value of y from the second equation into the first equation. Let's proceed step by step:
Step 1: Given equations:
1) x + 3y = 10
2) y = x + 2
Step 2: Substitute the value of y from equation (2) into equation (1):
x + 3(x + 2) = 10
Step 3: Distribute the 3 on the left side of the equation:
x + 3x + 6 = 10
Step 4: Combine like terms:
4x + 6 = 10
Step 5: Move the constant term to the other side of the equation:
4x = 10 - 6
Step 6: Simplify the right side:
4x = 4
Step 7: Divide both sides by 4 to solve for x:
x = 4/4
x = 1
Step 8: Now that we have the value of x, substitute it back into equation (2) to find y:
y = x + 2
y = 1 + 2
y = 3
Step 9: Check the solution by substituting the values of x and y into the original equations:
Equation 1: 1 + 3(3) = 10
1 + 9 = 10 (True)
Equation 2: 3 = 1 + 2
3 = 3 (True)
The solution to the system of equations is x = 1 and y = 3.

Alfred, Brandon and charles are the three participants in a race. In how many different ways can the three finish if it's possible for two or more participants to finish in a tie ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
Answer:
There are 13 different ways to finish the race
Step-by-step explanation:
To identify the number of different ways to finish the race we should categorized the types of win:
1. Without tie: the ways that are possible in this option are defined by the rule of multiplicación. There are 3 participants and 3 places, there are 3 possibles participant that can occupy the first place, then 2 possibles participants that can occupy the second place and one participant that can occupy the last place.
3 x 2 x 1 = 6
first place second place third place
So, there are 6 different ways to win without tie.
2. Double tie in the second place: This time there are 3 participant that can occupy the first place and the other participant are going to occupy the second place. So there are only 3 ways in this option, every option is defined by the winner. that's mean: the winner is Alfred, or is Brandon or is Charles.
3. Double tie in the first place: This option is like option 2, there are only 3 ways because every option is defined by the person that is in the second place. That's mean: the second place is occupy by Alfred, or by Brandon or by Charles.
4. All the participants end in tie: There are just one possibility in this option, all are the winners.
Finally there are 13 ways to end this race, 6 ways without tie, 3 ways with double tie in second place, 3 ways with double tie in first place and 1 way with all the participants in the same place.
Final answer:
Alfred, Brandon, and Charles can finish the race in 13 different ways, considering the possibilities of no ties, two-way ties, and a three-way tie. This is calculated by adding 6 permutations for no ties, 6 combinations for two-way ties, and 1 possibility for a three-way tie.
Explanation:
We need to calculate in how many different ways Alfred, Brandon, and Charles can finish a race given that there is the possibility of a tie. There are three scenarios to consider for the finishes: no ties, two-way ties, and a three-way tie.
No ties: This is a simple permutation of 3 participants, which gives us 3! (3 factorial) ways to finish, or 3 x 2 x 1 = 6 ways.
Two-way ties: For the two-way tie, we have 3 possible pairs (Alfred & Brandon, Alfred & Charles, Brandon & Charles), and for each pair, there is one person who does not tie, resulting in 2 finishing orders per pair, so 3 pairs x 2 orders = 6 ways.
Three-way tie: There is only 1 way that all three can tie.
Adding up the possibilities from each scenario, we get 6 (no ties) + 6 (two-way ties) + 1 (three-way tie) = 13 different ways they can finish the race.
