Is Triangle M'S'V' a reduction or an enlargement of the original Triangle MSV?
Answer:
Reduction
Step-by-step explanation:
In this problem, there are 2 triangles: the solid lines represent the preimage and the dotted lines represent the image. All of the vertices of the dotted lines are inside the solid line. This means that the preimage is larger than the image. If the preimage is larger, then a reduction has occurred.
There are 2 ways to tell that this is a reduction. The simplest is to just say that the image is inside the preimage and therefore smaller. More mathematically, you could also see that all of the coordinate pairs are closer to the origin by a scale factor of 2/3. Thus, the triangle must be smaller and reduced.
Which statement is sometimes true:
1. A square is a rhombus
2. A trapezoid is a parallelgram
3. A rectangle is a parallelogram
4. A rectangle is a square
Answer:
4. A rectangle is a square
Step-by-step explanation:
A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.

Answer:
15 strips of border will be needed
Step-by-step explanation:
First, convert each dimension for a mixed number into an improper fraction, We can now divide the length of the border into the length of the kitchen wall to find the number of strips needed, We can now use this rule for dividing fractions to evaluate the expression, and you get your answer.
Answer:
Therefore, 15 strips of border will be needed.

Store Y is offering $5 off the price of the shoes. Store Z is offering a 15 discount off the price of the shoes. Which statement about the sale price of these shoes is true?.
Leo should buy the shoes from the store Z, as store Z has the best selling price of $28. Statement 2 is true.
What is percentage ?Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.
Leo wants to buy some shoes. He found the shoes at three different stores for a price of $35.
The final price of store X-
As store X is offering 15% off the price of the shoes and the price of shoes is $35. Thus the selling price of store X is,
[tex]P_x=35-35\times\dfrac{15}{100}\\P_x=35-5.25\\P_x=29.75[/tex]
As store Y is offering $5 off the price of the shoes and the price of shoes is $35. Thus the selling price of store Y is,
[tex]P_y=35-35\times\dfrac{5}{100}\\P_y=35-1.75\\P_y=23.25[/tex]
As store Z is offering a 1/5 discount off the price of the shoes and the price of shoes is $35. Thus the selling price of store Z is,
[tex]P_y=35-35\times\dfrac{1}{5}\\P_y=35-7\\P_y=28[/tex]
Thus, Leo should buy the shoes from the store Z, as store Z has the best selling price of $28. Statement 2 is true.

Answer:
MY ANSWER IS THIS. IS. A. QUIZ.
Step-by-step explanation:
The cost of the apples is a function of their weight is true about the functional relationship shown in the graph. Correct option is c.
In the graph, the horizontal axis represents the weight (in pounds) of the apples, and the vertical axis represents the cost (in dollars) of the apples. As the weight of the apples increases, the cost also increases. This relationship shows that the cost of the apples is dependent on their weight, making it a functional relationship of "cost as a function of weight."

What is 40% of a circle of radius 225 feet
Answer:
About 63,617 ft²
Step-by-step explanation:
[] The area of a circle is equal to πr²
π(225)² ≈ 159,043
[] To find 40%, we can multiply our whole by 40%
-> 40% divided by 100, 0.4, becomes a decimal
159,043 * 0.4 = 63,617
-> Don't forget to add on the units once you are done, this problem was done in feet, since it is an area we used feet squared

Step-by-step explanation:
x is the hypotenuse of the triangle, for which one leg is given. Either the sine or the cosine relation can be used. We choose to use the cosine relation:
Cos = Adjacent/Hypotenuse
cos(53°) = 21/x
x = 21/cos(53°) ≈ 34.9

A two-sample z -interval for a difference between population proportions
A two-sample z -interval for a population proportion
A one-sample z -interval for a difference between population proportions
A one-sample z -interval for a population proportion
According to the hypothesis test, the option that gives the most appropriate method for creating such an estimate is:
A one-sample z-interval for a population proportion.
What is the hypothesis test?He will test if there is enough support to build a new middle school, that is, if the population proportion that supports the building of a new middle school is greater than a threshold.
Only one sample is taken from the district residents, hence the correct option is:

The volume of a rectangular solid is given by the polynomial 3x^4-3x^3-33x^2+54x. If the length of the solid is 3x and the width of the solid is x-2 Find the height?
Answer:
[tex]\mathsf{height}=x^2+x-9[/tex]
Step-by-step explanation:
Volume of a cuboid = L x w x h
(where L is the length, w is the width and h is the height)
[tex]\implies \mathsf{height=\frac{volume}{width \times length} }[/tex]
Given:
[tex]\mathsf{volume}=3x^4-3x^3-33x^2+54x[/tex]
[tex]\mathsf{width}=x-2[/tex]
[tex]\mathsf{length}=3x[/tex]
[tex]\implies \mathsf{height}=\frac{3x^4-3x^3-33x^2+54x}{3x(x-2)}[/tex]
Factor expression for volume
Factor out common term [tex]3x[/tex]: [tex]3x(x^3-x^2-11x+18)[/tex]
Factor [tex]x^3-x^2-11x+18[/tex]: [tex]3x(x-2)(x^2+x-9)[/tex]
[tex]\implies \mathsf{height}=\frac{3x(x-2)(x^2+x-9)}{3x(x-2)}[/tex]
Cancel the common factors [tex]3x(x-2)[/tex]:
[tex]\implies \mathsf{height}=x^2+x-9[/tex]
