Answer:
220 ft
Step-by-step explanation:
Given that:
Length of each curtain = 48 inches
Number of curtains required for Abby's curtain company = 55
Fabric of curtains is sold by the fabric store foot by foot.
Unit for conversion:
1 inch = [tex]\frac{1}{12}[/tex] foot
To find:
The fabric (in feet) needed by Abby.
Solution:
First of all, let us convert the length of each curtain (which is given in inches) to feet.
As per given hint:
1 inch = [tex]\frac{1}{12}[/tex] foot
48 inches = [tex]\frac{1}{12}[/tex] [tex]\times[/tex] 48 ft = 4 ft
So, length of one curtain is 4 ft.
Now, number of curtains required are 55.
Therefore, total length of curtains required can be found by multiplying the number of curtains with the length of one curtain.
Total length of curtain required = 55 [tex]\times[/tex] 4 = 220 ft
can someone please help? the question is an equilateral triangle is sometimes/always/never similar to a scalene triangle, because we can sometimes/always/never map one onto the other using only dial actions rigid transformations.
Answer:
An equilateral triangle is never similar to a scalene triangle, because we can never map one onto the other using only dilations and rigid transformations.
======================================================
Explanation:
An equilateral triangle is one where it has all three sides the same length. "Equi" means "equal" while "lateral" means "side". Any equilateral triangle also has all three angles the same measure (we consider it equiangular). Each angle is 60 degrees.
In contrast, a scalene triangle has all of its sides different, so consequently that means all of its three angles must be different as well. If you had exactly two angles congruent to one another, then the opposite sides would be a congruent pair of sides, but then that leads to an isosceles triangle. Also, if all three angles were the same, then we'd get back to an equilateral triangle. So in short, any scalene triangle has all of its angles different.
------------------
Let's consider two cases
Case 1) The scalene triangle has one angle that is 60 degrees, while the other two angles are not 60 degrees.Case 2) The scalene triangle doesn't have any angles that are 60 degrees.If case 1 happens, then we could match up one pair of 60 degree corresponding angles between the equilateral triangle and the scalene triangle. However, we won't have any more matches. This is because the other two angles aren't 60 (if they were then the triangle isn't scalene). Therefore case 1 leads to dissimilar triangles.
If case 2 happens, then we get the same conclusion as case 1. This time we don't have any angles matching up. Similar triangles must have corresponding angles match up and be congruent. Put another way: similar triangles are the same shape but not necessarily the same size.
------------------
After completing both cases, we can see that it is impossible to have an equilateral triangle be similar to a scalene triangle. In terms of transformations, we cannot apply any of the following
TranslationReflectionRotationDilationand have one triangle turn into the other. Again, it's all because the angles do not match up. We may have one matching pair, but we need all three pairs to match.
Yin wants to create figure Y′ that is similar to figure Y. Yin begins by reflecting figure Y across the y-axis.
Which of the following should Yin do next to get a figure similar to figure Y?
A. Yin should rotate the figure 90°.
B. Yin should dilate the figure by a scale factor of 2.
C. Yin should reflect the figure across the x-axis.
D. Yin should translate the figure 3 units to the left.
Answer: B) Dilate by scale factor of 2
====================================================
Explanation:
Your teacher isn't saying this directly, but I'm assuming s/he wants you to find a similar figure that isn't congruent to the original. Informally, your teacher seems to want you to find a figure that is the same shape but not the same size as the original.
If so, then any dilation will shrink or enlarge the image depending on the scale factor. So the new image will not be the same as the old one. In this case, a dilation with scale factor 2 means the new figure is twice as large (each side is twice as long). But the old image is similar to the new image. The angles keep their values and therefore we get the same shape. This is why choice B is the answer. Again this is assuming what I mentioned in the first paragraph.
Choices A, C, and D are all known as rigid transformations and they preserve the same size of the figure. Applying any of those operations will lead to the same figure (just rotated, reflected or shifted somehow). In other words, applying operations A,C, or D will have us get two congruent triangles. If two triangles are congruent, then they are automatically similar, but not vice versa. This is why we can rule out A,C, and D.
Answer:
B
Step-by-step explanation:
The table below shows all of the possible outcomes for rolling two six-sided number cubes.
A table with 36 possible outcomes. There are 9 desired outcomes.
What is the probability of rolling an even number first and an odd number second?
1/9
1/6
1/4
1/2
C. 1/4
There is a table with 36 possible outcomes. 9 of them are desired outcomes because they have an even number rolled first and then an odd number rolled second (a few random examples from the table would be 2,1, 2,3, 4,1, 4,5, 6,3 etc.)
All we have to do is make a fraction of the desired outcomes over the total number of possible outcomes. 9/36. That can be simplified into 1/4 and voilà, there is your answer.
Hope this helped ッ
My Answer:
The of getting an even number in first and an odd number second is 1/4.
That would be option C.
I just took the quiz in math on edge 2020/2021

Enny is selling candles for $3 each at a fund-raiser. If she starts selling with $4 to help her make change, how many candles, x, will she have to sell to end up with $19?
Answer:
5 candles
Step-by-step explanation:
Enny is selling candles for $3 at a fund raiser
She starts selling $4 to help her make change
Therefore the number of candles x that will be sold to get $19 can be calculated as follows
3x + 4= 19
3x = 19-4
3x= 15
x = 15/3
x= 5
Hence 5 candles must be sold to get $19

Answer:
y = 3( [tex]0.5^{x}[/tex] )
Step-by-step explanation:
Exponential function has the form f(x) = k [tex]b^{x}[/tex] where b > 0 and b ≠ 1
~~~~~~
3 = k × [tex]b^{0}[/tex] ⇒ k = 3
1.5 = 3( [tex]b^{1}[/tex] ) ⇒ b = 0.5
Thus, y = 3( [tex]0.5^{x}[/tex] )

Step-by-step explanation:
A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y = -8x2 + 242x – 1056
Answer:
774 dollars
Step-by-step explanation:
Given the amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation
y = -8x^2 + 242x – 1056
The company made her maximum profit when dy/dx = 0
dy/dx = -16x + 242
0 = -16x + 242
16x = 242
x = 242/16
x = 15.125
Get the maximum amount of the profit
Substituting x = 15.125 into the function we have:
y = -8(15.125)^2 + 242(15.125) – 1056
y = -8(228.77)+3,660.25-1056
y = -1,830.09+3,660.25-1056
y = 773.91
Hence the maximum amount of profit the company can make, to the nearest dollar is 774 dollars
Some simplify this plz 12x + 1.5x - 2-7
Answer:
13.5x + 5
Step-by-step explanation:
12x + 1.5x - 2 - 7 (you always want to work left to right)
13.5x - (2 - 7) (you are free to use the associative property here to isolate like terms)
13.5x - (-5) (remember a number less in value subtracted from a higher value will result in a negative value; giving you this value for instance.)
13.5x + 5 (now since it was basically subtracting a negative from 13.5x you can technically say the same thing by turning the negative value to a positive however you must do the opposite of subtraction as well.)

find two fraction with the same
denominator that are equivalent to 7/8 and 5/12
Answer:
21/24 and 10/24
Step-by-step explanation:
7/8 is equaivalent to 7*2/8*2 = 14/16 also to 7*3/8*3=21/24
5/12 is equivalent to 5*2/12*2= 10/24
so the denominators are 16 and 24 so are not the same so keep looking
the denominators 24 and 24 are same so your answer is
7/8 and 5/12 are same and have the same denominator to 21/24 and 10/24
