When translating a figure using a combination of two translations, is the resulting figure congruent to the original figure?
When translating a figure using two translations, the end result is a figure that is congruent to the original. This is due to the fact that translations move the shape without altering its size or orientation.
Explanation:Yes, when translating a figure using a combination of two translations, the resulting figure is congruent to the original figure. When a figure is translated, it is moved without being turned or flipped, the size and shape remains the same, hence making it congruent. For example, consider a parallelogram. If two different vectors A and B are chosen to translate it, following the rules of vector summation, the figure moved, known as the resultant vector retains the dimensions and angles of the original parallelogram, albeit in a different location.

how many square feet of outdoor carpet will we need for this hole
Answer: 36 sq
Step-by-step explanation: you add 24 to 12 and get 36
Answer:
[tex]36\text{ inch}^2[/tex]
Step-by-step explanation:
We have been given an image of outdoor carpet needed for a hole. We are asked to find the area of outdoor carpet needed for this hole.
We can see that there are two pieces needed to cover the given hole.
One pieces equal 24 square inches and another pieces equal 12 square inches.
[tex]\text{Area of carpet needed to cover the hole}=24\text{ inch}^2+12\text{ inch}^2[/tex]
[tex]\text{Area of carpet needed to cover the hole}=36\text{ inch}^2[/tex]
Therefore, [tex]36\text{ inch}^2[/tex] of carpet is needed to cover the given hole.
a plane is traveling due south. The wind is blowing 30° east of south at 50 miles/hour.if the plane resultant speed due to the wind is 180 miles/hour,what is the plane's actual speed. rounded to the nearest integer
The plane's actual speed is 135 miles/hour if the plane is traveling due south. The wind is blowing 30° east of south at 50 miles/hour option (C) 135 miles/hour is correct.

The complete question is:
A plane is traveling due south. The wind is blowing 30° east of south at 50 miles/hour. If the plane's resultant speed due to the wind is 180 miles/hour, what is the plane's actual speed, rounded to the nearest integer?
120 miles/hour130 miles/hour135 miles/hour140 miles/hourFrom the data given in the question:
Using Cosine Law:
c² = a² + b² - 2 ac cos C
180² = 50² + x² - (2×50)x cos 150°
32400 - 2500 - x² = 86.6x
29,900 - x² = 86.6 x
x² + 86.6x - 29900 = 0
After solving the above quadratic equation:
x = 135 miles/hour
Thus, the plane's actual speed is 135 miles/hour if the plane is traveling due south. The wind is blowing 30° east of south at 50 miles/hour option (C) 135 miles/hour is correct.

Add or subtract. Show your work for each problem
a. (x^2-4x+5)+(7x^2+2x-3) b. (7x^2+4x-6)-(2x^2-3x+1)
To solve this problem you must apply the proccedure shown below:
a) You must sum terms with same exponents, therefore, you have that the sum of these two polynomials is:
[tex] (x^{2}-4x+5)+(7x^{2}+2x-3) [/tex]
[tex] 8x^{2} -2x+2 [/tex]
b) First, you must mulitply the signs of the second polynomial by the negative sign, and them, you apply an algebraic sum. Therefore, the result is:
[tex] (7x^{2}+4x-6-2x^{2}+3x-1) \\ 5x^{2} +7x-7 [/tex]
The answers are: a)[tex] 8x^{2} -2x+2 [/tex]; b) [tex] 5x^{2} +7x-7 [/tex]
a)
x² - 4x + 5 + 7x² + 2x - 3
8x² - 2x + 2
b)

Tennis balls are sold in tubes that hold 3 tennis balls each. A store stacks 2 rows of tennis ball tubes on its shelf. Each row has 7 tubes in it. How many tennis balls are there in all?
There are a total of 42 tennis balls on the shelf.
To determine the total number of tennis balls on the shelf, we first need to find out how many tennis ball tubes are there. Each row has 7 tubes and there are 2 rows:
Number of tubes per row = 7
Number of rows = 2
Total number of tubes = 7 tubes/row × 2 rows = 14 tubes
Since each tube contains 3 tennis balls, we multiply the total number of tubes by the number of tennis balls per tube:
Number of tennis balls per tube = 3
Total number of tennis balls = 14 tubes × 3 tennis balls/tube = 42 tennis balls
Therefore, the store has a total of 42 tennis balls on the shelf.
What is Eleven less than two times a number is equal to 27
11 less implies: -11
two times a number (x) implies: 2x
equal to 27 implies: = 27
Set the equation together.
2x - 11 = 27 is your equation.
Solve for x. Note the equal sign. What you do to one side you do to the other. Add 11 to both sides
2x - 11 (+11) = 27 (+11)
2x = 38
Isolate the x. Divide 2 from both sides.
2x/2 = 38/2
x = 19

Pedro was simplifying four over seven divided by five over eight. and his work is shown below. Identify where he made his error. Original problem: four over seven divided by five over eight. Step 1: four over seven multiplied by eight over five . Step 2: four times five over seven times eight. Step 3: twenty over fifty-six. Step 4: five over fourteen.
Answer: it's the 2nd step
Pedro made an error in step 2, he crossed multiplied instead of multiplying.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
Pedro was simplifying four over seven divided by five over eight.
= (4/7)/(5/8)
= (4/7)x(8/5)
= 32/35
In Step 2 Pedro made mistake, he crossed multiplied instead of multiplying the numerators, and then the denominators.
Thus, Pedro made an error in step 2, he crossed multiplied instead of multiplying.
