A polygon is translated according to the rule (x,y) - (x – 3, y) to create a new polygon. Which statement is true?
Answer: D
Step-by-step explanation:
This is a translation, so this means side lengths are preserved because a translation is a rigid motion. If all the side lengths are the same, then the perimeters must be the same.

Sarah has two similar regular pyramids with pentagon-shaped bases. The smaller has a scale factor of 2:3 when compared to the larger. Only the smaller pyramid is shown.
She calculates the area of the base of the pyramid (through long, hard work) to be 220.22 square units. The height of the pyramid is 15 units. Now she needs to calculate the volume of the pyramid.
(a) Calculate the volume of the pyramid for Sarah.
(b) "Oh, no!" Sarah exclaims. "Now I have to go through all this hard work again to find the volume of the larger pyramid!" Does she? Explain.
(c) Calculate the volume of the larger pyramid for Sarah.
Answer:
a) The volume of the pyramid 440.44 cube units
(b) No she doesn't
(c) The volume of the larger pyramid is 1,486.485 cube units
Step-by-step explanation:
The given parameters are;
The scale factor of the pyramids, S.F. = 2:3
The base area of the small pyramid, = 110.11 square units
The height of the small pyramid, h₁ = 12 units
(a) The volume of a pyramid, V = (1/3) × Area of base × The height of the pyramid
Therefore;
The volume of the small pyramid, V₁ = (1/3) × 110.11 square units × 12 units
V₁ = 440.44 cube units
The volume of the small pyramid, V₁ = 440.44 cube units
(b) No she does not have to go through all the hard work again to find the volume of the larger pyramid
She only has to make use of the scale factor relationships of the two pyramid to calculate the volume of the larger pyramid
The volume scale factor = (The linear scale factor)³
(c) The linear scale factor of the pyramids = 2:3 = 2/3
Therefore;
The volume scale factor of the pyramids = (2/3)³ = 8/27
To find the volume of the larger pyramid, V₂, from the volume of the smaller pyramid, V₁, we multiply the volume of the smaller pyramid, V₁, by 27/8 as follows;
V₂ = V₁ × (27/8)
Therefore;
The volume of the larger pyramid, V₂ = 440.44 cube units × (27/8) = 1,486.485 cube units
The volume of the larger pyramid, V₂ = 1,486.485 cube units.
100 POINTS!!! Which statement about rational numbers is correct?
Rational numbers have decimal expansions that are non-repeating.
Rational numbers have decimal expansions that repeat or terminate.
Rational numbers do not have decimal expansions.
Rational numbers only have decimal expansions that terminate.
Answer: Rational numbers have decimal expansions that repeat or terminate.
Step-by-step explanation:
The explanation of this is the non-terminating but repeating decimal expansion means that although the decimal representation has an infinite number of digits, there is a repetitive pattern to it. The rational number whose denominator is having a factor other than 2 or 5, will not have a terminating decimal number as the result.

Inventory Heung-Soo is responsible for checking a shipment of technology equipment that contains laser printers that cost $700 each and color monitors that cost $200 each. He counts 30 boxes on the loading dock. The invoice states that the order totals $15,000. Write a system of two equations that represents the situation outlined above. How many laser printers and how many color monitors were delivered?
Answer:
P + M = 30
700P + 200M = 15000
Number of laser printers = 18
Number of color monitors = 12
Step-by-step explanation:
Let P = number of laser printers
Let M = number of color monitors
Given total number of boxes = 30
⇒ P + M = 30
Given:
$700 = cost of laser printer$200 = cost of color monitor$15000 = total cost of order⇒ 700P + 200M = 15000
Rewrite P + M = 30 to make P the subject:
⇒ P = 30 - M
Substitute into 700P + 200M = 15000 and solve for M:
⇒ 700(30 - M) + 200M = 15000
⇒ 21000 - 700M + 200M = 15000
⇒ 500M = 6000
⇒ M = 12
Substitute found value for M into P = 30 - M and solve for P:
⇒ P = 30 - 12 = 18

Express 50grams into ounces
Answer:
1.7637
Step-by-step explanation:
Welcome to 50 grams to ounces. If you have been wondering about how many ounces in 50 grams, then you are perfectly right here. 50 grams can also be written as 50 g, and the symbol for ounces is oz. In other words, this article is about the conversion of 50 g to oz, to the unit international avoirdupois ounce to be exact, but we also explain you the conversion into the international troy ounce. Read on to learn everything about 50 grams in ounces.
To change 50 g to oz divide the mass in grams by 28.349523125. The 50 grams to ounces formula is [oz] = [50] / 28.349523125. Thus, we get (all results rounded to 2 decimals):
50 g to oz = 1.76 oz
50 g to ounces = 1.76 ounces
50 grams to ounces = 1.76 oz
Fifty grams to ounces equal 1.76 international avoirdupois ounces, the unit used to measure grocery products (mass) in retail stores in the United States for example.
The result also applies to 50 g in oz for dry foods in bulk, but is not valid for liquids, whose volumes are measured in fluid ounces: 50 grams to ounces ≠ 50 grams to fluid ounces.
Finally, 50 grams to troy ounces results in 1.61 oz as the formula is [troy oz] = [50] / 31.1034768. Thus, 50 gram gold to ounces is 1.61 international troy ounces when converted.

In the similarity transformation of ABC to DEF, ABC was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [(x-5, y+1)]
How to complete the similarity transformation?From the figure, we can see that the side lengths of the triangle DEF are twice the side lengths of ABC
This means that ABC must be dilated by a scale factor of 2
Also, both triangles are on either sides of the x-axis.
This means that ABC must be reflected across the x-axis
Lastly, the triangle must be translated 5 units left and 1 unit up

(2, 0)
(0, 3)
(0, 2)
(3, 0)
(0, 0)
(5, 0)
The graph of the function is a linear function
The graph has no critical point
How to determine the critical points
The points on the lines of the graphs are:
(x,y) = {(0,2) (4,0)}
Start by calculating the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{0-2}{4 - 0}[/tex]
[tex]m =-0.5[/tex]
So, the linear equation is:
[tex]y = -0.5x + 2[/tex]
The above function is a linear function, and a linear function has no critical point
Hence, the graph has no critical point

An isosceles triangle has an angle that measures 90°. Which other angles could be in that isosceles triangle? Choose all that apply.
Answer:
Step-by-step explanation:
If one angle = 90 degrees, then the other 2 added together must also = 90.
There is only 1 answer to this, since the triangle is isosceles..
x + x = 90 Combine
2x = 90 Divide by 2
x = 90/2
x = 45
So both acute angles = 45 degrees.
Can u solve it?
Find x,y,v and u.
Explanation:
Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.
the optimal way is to do it with Cramer's rule.
First, find the determinant and then find the determinant x, y, v, u.
Afterward, simply divide the determinant of variables by the usual determinant.
eg. [tex]\frac{Dx_{} }{D}[/tex] and etc.
I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.

A survey found that women spend on average $146.21 on beauty products during the summer months. Assume the standard deviation is $29.44. Find the percentage of women who spend less than $160.00. Assume the variable is normally distributed.
see the attached image.
The percentage of women who spend less than $160.00 is 68.03%.
What is Standard Deviation?The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
standard deviation = $29.44.
A survey found that women spend on average $146.21
so, the z- score
= 160 - 146.21 / 29.44
= 13.79/ 29.44
= 0.4684
Now, P( z< 0.4684)= 0.6803= 68.03%
