Answer:
D) Isometría
Step-by-step explanation:
Hola, D es la respuesta correcta porque la isometría no es una transformación isométrica, veamos por qué.
Una Transformación Isométrica es el cambio de forma, pero no por tamaño ni forma de la figura.
A. La traslación es una transformación isométrica porque desliza la figura a otro lugar, sin afectar su forma o tamaño.
B. La simetría es una transformación isométrica porque técnicamente es un reflejo, una vez más no afecta el tamaño o la forma de la figura.
C. La rotación es una transformación isométrica porque gira la figura, sin afectar el tamaño o la forma de la figura.
E. La teselación es una transformación isométrica porque une la misma forma, sin afectar el tamaño o la forma de la figura.

A company needs two loads of sand to make an indoor beach area when employee picnic one load of sand weigh 4 tons and the other load Waze 7500 pounds what is the total weight of sand in pounds
Answer:
15500 pounds
Step-by-step explanation:
The weight of one load is 4 tons and the weight of other load is 7500 pounds.
We know that, 1 ton = 2000 pounds
4 tons = 8000 pounds
Total weight = 8000 pounds + 7500 pounds
Total weight = 15500 pounds
So, the total weight of sand is 15500 pounds.
Which interval notation represents the set of all numbers from -9 to 0, inclusive?
Answer:
[-9,0]
Step-by-step explanation:
You use brackets to indicate that the numbers, in this case -9 and 0, are included in the interval.
You use parentheses to indicate that the numbers are excluded from the interval.
Since we want to include the numbers in the interval, we use the brackets.
The answer is [-9,0]

Answer:
£7448
Step-by-step explanation:
Simple interest (I) is calculated as
I = [tex]\frac{PRT}{100}[/tex]
P is principle ( amount invested), R is rate of interest and T is time in years.
Here P = £5600, R = 11 and T = 3 , thus

Given that a rectangle has a length of 5/2x + 10 with a width of 5/2x + 5, formulate an expression to represents the area of the rectangle.
Answer:
A = ²⁵/₄x² + ⁷⁵/₂x + 50Step-by-step explanation:
L = ⁵/₂x + 10
W = ⁵/₂x + 5
A = L•W
A = (⁵/₂x + 10)(⁵/₂x + 5)
A = ⁵/₂x•⁵/₂x + ⁵/₂x•5 + 10•⁵/₂x + 10•5
A = ²⁵/₄x² + ²⁵/₂x + ⁵⁰/₂x + 50
A = ²⁵/₄x² + ⁷⁵/₂x + 50
Or if yoy mean:
L = 5/(2x) + 10
W = 5/(2x) + 5
A = [5/(2x) + 10][5/(2x) + 5] = 25/(4x²) + 75/(2x) + 50

The second side of a triangular deck is 3 feet longer than the shortest side, and the third side is3 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 52 feet, what are the lengths of the three sides?
Answer:
13, 16, 23
Step-by-step explanation:
The first side is x.
The second side is x + 3
The third side is 2x - 3
(x) + (x +3) + (2x - 3) = 4x
4x = 52
x = 13
If m∠XWZ = 90, what is x?
Right angle X W Z is divided into 2 acute angles labeled 5 x plus 5 degrees and 2 x plus 8 degrees.
Answer: x=11
Step-by-step explanation:
If m∠XWZ = 90 and is divided into 2 acute angles labeled 5x+5 degrees and 2x+8 degrees then the value of x is 11.
Given,
m∠XWZ = 90.
Right angle ∠XWZ is divided into 2 acute angles labeled as:
- 5x + 5 degrees
- 2x + 8 degrees.
We need to find the value of x.
What is an acute angle?An acute angle means angles that are less than 90 degrees.
If an angle is divided, the sum of the divided angles must be equal to the angle divided.
Find the right angle.
m∠XWZ = 90
Find the acute angles that are being divided.
= 5x + 5° and 2x + 8°
Find x.
Since m∠XWZ is divided we have,
90° = 5x + 5° + 2x + 8°
Now,
Add the like terms.
90 = 7x + 13
Subtract 13 on both sides.
90 - 13 = 7x
77 = 7x
Divide both sides by 7.
11 = x
x = 11
We can crosscheck the angles:
90° = 5x + 5° + 2x + 8°
90 = 5x11 + 5 + 2x11 + 8
90 = 55 + 5 + 22 + 8
90 = 60 + 30
90 = 90
Thus if m∠XWZ = 90 and is divided into 2 acute angles labeled 5x+5 degrees and 2x+8 degrees then the value of x is 11.

You want to put a logo on each cell phone holder you make. Sew-on logos cost 2.30 for 10. Stick-on logos cost 9.40 for 100. Divide the cost by the number of logos for both types
Answer:
[tex]Rate = \$0.23[/tex] and [tex]Rate = \$0.094[/tex]
Step-by-step explanation:
Given
Sew-on logos
Cost = $2.30
Units = 10
Stick-on logos
Cost = $9.40
Units = 100
Required
Divide cost by units, in both cases
When we divide cost by units, it gives the unit rate.
i.e.
[tex]Rate = \frac{Cost}{Units}[/tex]
FOR SEW-ON LOGOS
Substitute $2.30 for Cost and 10 for Units
[tex]Rate = \frac{\$2.30}{10}[/tex]
[tex]Rate = \$0.23[/tex]
FOR STICK-ON LOGOS
Substitute $9.40 for Cost and 100 for Units
[tex]Rate = \frac{\$9.40}{100}[/tex]
[tex]Rate = \$0.094[/tex]
Hence, the solution is
[tex]Rate = \$0.23[/tex] and [tex]Rate = \$0.094[/tex]

82, 77, 72, 67, 62 ....... The recursive pattern in the sequence above is latex-_ (be sure to show if it is positive or negative). The 4th term in the sequence is . An explicit formula that I can use to write for this sequence is latex-_ . The value of the 100th term is .
Answer:
a. It is a negative pattern
b. Fourth term is 67
c. Explicit formula is Tn = 87 - 5n where n is the number of the term.
d. The value of the 100th term is -413
Step-by-step explanation:
1.Firstly, we want to know if the pattern is positive or negative.
Looking at the pattern, we can see our first term as 82, second as 77, third as 72.
What this show is that the pattern is decreasing as we move on from one term to another. So we can say it is a negative recursive pattern.
2. We are asked which term is the 4th.
This is quite obvious from the spelt out pattern.
82 77 72 67
1....2......3.....4
67 is the fourth term.
3. We want an explicit formula for the sequence.
What this question is asking us is a formula such that we can use at any point in time to calculate the value of the term at that point.
Firstly we have the first term as 82.
We need the common difference.
Mathematically this is the second term minus the first term which is same as the third term minus the second term.
That would be; 77-82 = 72-77 = -5
Mathematically the nth term of an arithmetic sequence is;
Tn = a + (n-1) d
Where in this case a is 82 and d is -5
Substituting these values, we have;
Tn = 82 + (n-1)-5
Tn = 82 -5n + 5
Tn = 82 + 5 -5n
Tn = 87 -5n
Where Tn is the term we are looking for while n is the number of the term.
4. Value of the 100th term
Simply substitute the value of 100 for n in the explicit formula.
That would be;
87 -5(100) = 87-500 = -413

What are exponents and powers?We use exponents and powers when we want to write very large numbers or very small numbers in a simplified manner.
Example:
8 = 2 x 2 x 2 = [tex]2^{3}[/tex].
Where 2 is the base and 3 is the exponents.
72 = 8 x 9 = [tex]2^{3} \times3^{2}[/tex].
Here we have two bases 2 and 3 and two exponents 3 and 2.
8 / 9 = [tex]\frac{2^{3} }{3^{2} }[/tex] = [tex]2^{3} \times3^{-2}[/tex].
Here the bases are 2 and 3 and exponents are 3 and -2.
We have
[tex]3\sqrt[4]{z}~.~3z^{\frac{3}{4} }[/tex]
Here,
[tex]\sqrt[4]{z}[/tex] can be written as [tex]z^{\frac{1}{4} }[/tex].
[tex]z^{\frac{1}{4} }~.~z^{\frac{3}{4} }[/tex] can be written as :
[tex]z^{\frac{1}{4} +\frac{3}{4} }\\\\ z^{\frac{4}{4} } \\\\z^{1} = z[/tex]
Now we have,

3 x 3 x z
[tex]3^{2}[/tex] x z
9 x [tex]z^{1}[/tex]
So, comparing with k . [tex]z^{n}[/tex]
we have,
k = 9 and n = 1.

A washer and a dryer cost $600 combined. The cost of the washer is three times the cost of the dryer. What is the cost of the dryer?
Answer:150
Step-by-step explanation:
600/4=150 (150)3=450 450+150=600
Answer: 150 dollars
Step-by-step explanation: Because the dryer is equal to washer divided by 3 you can substitute Washer/3 in the equation
W+ W/3=600
multiply both sides by 3
3W+W=1800
4W=1800
Divide both sides by 4
The answer to W is 450 dollars which you then divide by three to get 150 dollars

Answer:
x = -7/2
Step-by-step explanation:
(1/4) ^ (x+1) = 32
Rewriting 32 as 2^5 and 1/4 and 2^-2
2^-2 ^ (x+1) = 2^5
We know that a^b^c = a^ ( b*c)
2 ^ (-2x-2) = 2 ^ 5
Since the bases are the same, the exponents have to be the same
-2x-2 = 5
Add 2 to each side
-2x = 7
Divide by -2
x = -7/2
