Answer: Your answer is 30 percent
Answer:
30%
Step-by-step explanation:
Make a fraction
6/20
There a few different ways to find a percentage, but in this case, I will change the fraction to be out of 100
20 × what = 100?
20 × 5 = 100
Multiply the denoninator by 5
6 / 20 × 5
What we do to the denominator, we must also do to the numerator
6 × 5 / 20 × 5
30/100
Percentages are out of 100, meaning if the fraction has the denominator "100," the numerator is the answer
30%
Ms.Keller is racing bob to see who can read the book faster. the book has 342 pages ms. Keller has already completed 300 pages. If she reads 2 pages per min how mint min will it take her to Finnish the book
Answer:
21 minutes
Step-by-step explanation:
Ms.Keller is speed reading a book that has 342 pages, she has already completed 300 of them and can read 2 pages per minute. The question is asking how long it'll take her to finish this book.
So we know the vital information that Keller reads two pages per minute and she only has 42 pages left of the book, this is all we need to answer the question.
All we need to do is divide 42 by 2 :
42 / 2
21
Therefore, it'll take Ms.Keller 21 minutes to finish the book at the constant speed
Write the equation of the parabola in vertex form.
Vertex:(4,4)
Point :(2,-8)
Answer:

y = a(x-4)^2 + 4
Plug in (2,-8) and solve for a:
-8 = a(2-4)^2 + 4
a = -3
y = -3(x-4)^2 + 4

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]
it is given that
area of the rectangle = y
width of the rectangle = x
so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]
perimeter = 64
What is the perimeter of a rectangle?Perimeter is the sum of all four sides of the rectangle.
we can say that,
2(length + breadth) = 64
[tex]2( \frac{y}{x} + x)=64\\\\[/tex]
[tex]\frac{y}{x} + x= 32[/tex]
[tex]\frac{y + x^{2} }{x} = 32[/tex]
[tex]y+x^{2} = 32x[/tex]
[tex]y = -x^{2} +32[/tex]

The scale used is 1 inch : 8 feet.
What is the scale?The blueprint is a smaller version of an original larger image. The scale would be used to reduce the size of the actual dimensions of the rectangle.
In order to determine the scale, divide the actual dimensions of the rectangle by the dimensions of the rectangle. #
Scale = 96 feet / 12 inches = 8

Answer:
87
Step-by-step explanation:
Here g is equalling -1, so substitute -1 for g in the equation. The equation is now 59 - 28(-1) = blank. Multiply 28 by -1 to get -28.
The equation is now 59 - (-28). There are two negatives in a row, so that becomes a plus sign. That makes it 59 + 28. Simply add to get 87 as your answer.

Step-by-step explanation:
we know that (x-5) and (y-6) must add up to 129 because 180-51 is 129
now let's plug in the values to see
51-5= 66 63-6 = 57
57+66 is 123, not this one, let's repeat the same step
77-5 is 72, 63-6 is 57, these added is 129

Pythagorean Method
Trapezoid ABCD has vertices A(-5,9) B(-2,9) C(-8,0) D(1,0) after a translation of 2 units right and 3 units down followed by a dilation with a scale factor of 2/3. What are the vertices of trapezoid RSTU
Answer:
(-2,4), (0,4), (-4,-2) and (2,-2)
Step-by-step explanation:
Given
[tex]A = (-5,9)[/tex]
[tex]B = (-2,9)[/tex]
[tex]C = (-8,0)[/tex]
[tex]D = (1,0)[/tex]
[tex]Translation: 2\ units\ right\ \& \ 3\ units\ down[/tex]
[tex]Dilation: \frac{2}{3}[/tex]
Required
Determine the vertices of the image RSTU
When a coordinate (x,y) is translates b units right, the new coordinate is: (x + b, y)
So, translation 2 units right gives:
[tex]A = (-5,9)[/tex] ---> [tex]A' = (-5 + 2,9) = (-3,9)[/tex]
[tex]B = (-2,9)[/tex] ---> [tex]B' = (-2 + 2,9) = (0,9)[/tex]
[tex]C = (-8,0)[/tex] ---> [tex]C' = (-8 + 2,0) = (-6,0)[/tex]
[tex]D = (1,0)[/tex] --- > [tex]D' = (1 + 2,0) = (3,0)[/tex]
When a coordinate (x,y) is translates b units down, the new coordinate is: (x, y-b)
So, translation 3 units down gives:
[tex]A' = (-3,9)[/tex] ---> [tex]A" =(-3,9-3) =(-3,6)[/tex]
[tex]B' = (0,9)[/tex] --> [tex]B" =(0,9-3) =(0,6)[/tex]
[tex]C' = (-6,0)[/tex] --> [tex]C" =(-6,0-3) = (-6,-3)[/tex]
[tex]D' = (3,0)[/tex]--> [tex]D"=(3,0-3) = (3,-3)[/tex]
Lastly, dilation of 2/3 gives:
[tex]New = Old * \frac{2}{3}[/tex]
[tex]R = (-3,6) * \frac{2}{3} = (-2,4)[/tex]
[tex]S = (0,6) * \frac{2}{3} = (0,4)[/tex]
[tex]T = (-6,-3) * \frac{2}{3} = (-4,-2)[/tex]
[tex]U = (3,-3) * \frac{2}{3} = (2,-2)[/tex]
Hence, the coordinates of RSTU are: (-2,4), (0,4), (-4,-2) and (2,-2)
