Answer:
$3.60 per pound
Step-by-step explanation:
you can set up a proportion: $ / lbs = $ / lb
let 'x' = cost of 1 pound of chicken:
9 / 2.5 = x / 1
cross-multiply:
2.5x = 9
x = 9/2.5
x = 3.6
on a girls volleyball team 9 out of 12 team members have played in previous years based on this information if 80 girls are in a volleyball league than how many could be expected to have played the year before?
Answer: I believe the answer is 60
Step-by-step explanation:
9/12 = 3/4
If we do cross multiplying x over 80 times 3/4 it equals 60.

Answer:
1. a) The scale factor that transform ΔKLP to ΔK'L'P' is a dilation of 3/2
b) The rule represented is that if the scale factor is larger than 1, the image formed is larger than the preimage
2. a) The scale factor of the dilation is 3/4
b) The rule represented by the dilation is a scale factor of less than 1 produces an image with a distance from a given point which is less than the distance of the preimage from the given point
Step-by-step explanation:
1. The coordinates of the triangle ΔKLP are;
K(-4, 2), L(2, 6), P(4, -6)
The coordinates of the points of triangle ΔK'L'P' are;
K'(-6, 3), L'(3, 9), P'(6, -9)
The length of segment KL = √((2 - (-4))² + (6 - 2)²) = 2·√13
The length of segment LP = √((4 - 2)² + (-6 - 6)²) = 2·√37
The length of segment KP = √((4 - (-4))² + (-6 - 2)²) = 8·√2
The length of segment K'L' = √((3 - (-6))² + (9 - 3)²) = 3·√13
The length of segment L'P' = √((6 - 3)² + (-9 - 9)²) = 3·√37
The length of segment K'P' = √((6 - (-6))² + (-9 - 3)²) = 12·√2
Therefore, K'L'/KL = 3·√13/(2·√13) = L'P'/LP = (3·√37/(2·√37)) = K'P'/KP =(12·√2/(8·√2)) = 3/2
Therefore, the scale factor that transform ΔKLP to ΔK'L'P' is a dilation of 3/2
The rule represented is that if the scale factor is larger than 1, the image formed (here ΔK'L'P') is larger than the preimage (ΔKLP)
2. The location of the preimage, W(-12, -4), the location of the image after the dilation W'(-9, -3)
Taking the origin O(0, 0), as the center of dilation, we have;
The length of the preimage W(-12, -4) from the origin = √((-12 - 0)² + (-4 - 0)²) = 4·√10
The length of the image W'(-9, -3) from the origin = √((-9 - 0)² + (-3 - 0)²) = 3·√10
Therefore, the scale factor of the dilation = W'O/WO = 3·√10/(4·√10) = 3/4
The scale factor of the dilation = 3/4
The rule represented by the dilation is that for a scale factor less than 1, the distance between the point of the image from a given point is less than the distance of the point of the preimage from the same point
Which equation represents a line that passes through (2, -1/2) and has a slope of 3?
A) y-2=3(x+1/2). B)y-3=2(x+1/2)
C)y+1/2=3(x-2)
D)y+1/2=2(x-3)
Answer:
C
Step-by-step explanation:
The line passes through the point (2, -1/2) and has a slope of 3.
We can use the point-slope form, given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where (x₁, y₁) is a point, and m is the slope.
Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:
[tex]\displaystyle y-\Big(-\frac{1}{2}\Big)=3(x-(2))[/tex]
Simplify:
[tex]\displaystyle y+\frac{1}{2}=3(x-2)[/tex]
Therefore, our answer is C.

5. Reflection: Marissa wants to describe the relationship between the scale factor and perimeter of an image and its pre-image and between the scale factor and area of an image and its pre-image. What should she say about the relationship between the scale factor and perimeter of an image and its pre-image? What should she say about the relationship between the scale factor and the area of an image and its pre-image?
Answer:
see below
Step-by-step explanation:
Answer in your own words:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape. Which can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.
• The scale factor of a dilated figure is denoted by 'r' or 'k'.
• If the scale factor is more than 1 (k > 1), the image is enlarged.
• If the scale factor is less than 1 (0< k <1), the image is contracted.
• If the scale factor is 1 (k = 1), the image remains the same.
• The scale factor cannot be zero.
Scale factor = k
Pre-image lengths: a, b
(perimeter = 2a + 2b)
Image lengths: ka, kb
(perimeter = 2ka + 2 kb or k (2a + 2b))
Marissa needs to say that the perimeter of the image is the perimeter of the pre-image times the same scale factor.
area of the pre-image = ab
area of the image = (ka)(kb) or k^2 (ab) (The area of the image is the area of the preimage times the square of the scale factor)
Scale factor 5 (then repeat it with scale factor 6)
length of the pre-image = 3 x 4
(perimeter = 2 (3 + 4) = 2(7) = 14)
length of the image = (3x5) x (4x5) = 15 x 20= 300
(perimeter = 2 (15 + 20) = 2 (35) = 70 or 14 x 5 = 70
area of the pre-image = 3 x 4 = 12
area of the image = 15 x 20 = 300
12 x (5^2) = 12 x 25 = 300
Please help me. I need how to do the problem too
Answer: Choice A. (8, 4)
==========================================================
Explanation:
Because x = 2y, we can replace every copy of x with 2y
Let's do so in the second equation
3x - 4y = 8
3(x) - 4y = 8
3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y
6y - 4y = 8
2y = 8
y = 8/2 ..... divide both sides by 2
y = 4
Use this y value to find x
x = 2y
x = 2*4
x = 8
So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

Answer:
That means the missing side length is 15
Step-by-step explanation:
We use the Pythagorean theorem to find the hypotenuse. The hypotenuse for this triangle is 17. The equation for the Pythagorean theorem is a^2 + b^2 = c^2. Our equation is x^2+64 = 289. We can now subtract 64 from both sides and get 225. The square root of 225 will be 15.
Answer:
hi
Step-by-step explanation:
[tex] {c}^{2} = {a}^{2} + {b}^{2} \\ {8}^{2} + {b}^{2} = {17}^{2} \\ {b}^{2} = {17}^{2} - {8}^{2} \\ {b}^{2} = 289 - 64 \\ {b}^{2} = 225 \\ b = \sqrt{225} \\ b = 15[/tex]

Joe has read 30% of a book. He has 14 more pages to finish. How many pages are there in the book?
Since Joe has read 30% of the book, that means that 14 pages is 70% of the book. That means that two pages equals 10%. Therefore, the book has 20 pages.
70% = 14
so 30% = 6
total pages = 14+6=20
