The coordinates of C' are [tex]C'(x,y) = (0.25, -3.5)[/tex].
Step-by-step explanation:
The statement is incomplete, we present the complete statement below: Triangle ABC is dilated using the dilation rule [tex]D = 0.5\cdot (x,y)[/tex] to form triangle A’B’C’. Point A is located at [tex]A(x,y) = (10, 7.5)[/tex], point B is located at [tex]B(x,y) =(-5,2)[/tex], and point C is located at [tex]C(x,y) =(0.5,-7)[/tex]. What are the coordinates of A’? What are the coordinates of B’? What are the coordinates of C’?
We proceed to calcultate the coordinates of the triangle A'B'C' hereafter:
What are the coordinates of A'?
[tex]A'(x,y) = 0.5\cdot A(x,y)[/tex] (1)
[tex]A'(x,y) = 0.5\cdot (10, 7.5)[/tex]
[tex]A'(x,y) = (5, 3.75)[/tex]
The coordinates of A' are [tex]A'(x,y) = (5, 3.75)[/tex].
What are the coordinates of B'?
[tex]B'(x,y) = 0.5\cdot B(x,y)[/tex] (2)
[tex]B'(x,y) = 0.5\cdot (-5,2)[/tex]
[tex]B'(x,y) = (-2.5, 1)[/tex]
The coordinates of B' are [tex]B'(x,y) = (-2.5, 1)[/tex].
What are the coordinates of C'?
[tex]C'(x,y) = 0.5\cdot C(x,y)[/tex] (3)
[tex]C'(x,y) = 0.5\cdot (0.5,-7)[/tex]
[tex]C'(x,y) = (0.25, -3.5)[/tex]
The coordinates of C' are [tex]C'(x,y) = (0.25, -3.5)[/tex].

Tasks: Find the price per pound of each turkey. Stater Bros.: Ralphs: Food for Less: Which store has the best price? Store name:
Answers
Answer: See explanation
Step-by-step explanation:
At Stater Bros., she found an 18 lb turkey for $21.42. The cost per pound will be:
= $21.42 / 18
= $1.19 / lb
At Ralphs, she found a 20 lb turkey for $24.20. The cost per pound will be:
= $24.20 / 20
= $1.21 / lb
At Food for Less, she found a 17 lb turkey for $18.36. The price per pound will be:
= $18.36 / 17
= $1.08 / lb
Based on the explanation, Food for Less has the best price as it's cheaper than others.

A recipe for chicken marinade says, ''Mix 3 parts oil with 2 parts soy sauce and 1 part orange juice. ''if you need 42 cups of marinade in all,how much of each ingredient should you see?
Answers
Answer:
Parts of oil in 42 cups of marinade = 21 cups
Parts of soy sauce in 42 cups of marinade = 14 cups
Parts of orange juice in 42 cups of marinade = 7 cups
Step-by-step explanation:
Given that:
Parts of oil = 3
Parts of soy sauce = 2
Part of orange juice = 1
Total cups of marinade = 42
To find:
How much of each ingredient should be there ?
Solution:
This problem can be solved by taking the ratio of ingredients into account.
The ratio is:
Oil : Soy Sauce : Orange Juice = 3 : 2 : 1
So, we can let the parts of oil = [tex]3x[/tex]
Parts of soy sauce = [tex]2x[/tex]
Parts of orange juice = [tex]x[/tex]
As per the question statement:
[tex]3x+2x+x=42\\\Rightarrow 6x=42\\\Rightarrow x =7[/tex]
So, parts of oil in 42 cups of marinade = 3 [tex]\times[/tex] 7 = 21 cups
Parts of soy sauce in 42 cups of marinade = 2 [tex]\times[/tex] 7 = 14 cups
Parts of orange juice in 42 cups of marinade = 7 cups

Which set of values could be the side lengths of a 30-60-90 triangle?
A. (5,5,√2,10)
B. (5,5,√3,10)
C. (5,5,10,√2)
D. (5,10,10,√3)
Answers
Answer:
B
Step-by-step explanation:
In a right triangle, the three angles are 30, 60 and 90 respectively. Let the side opposite the 30 degree Angle be A. The hypotenuse is 2a.
According to Pythagorean theorem, the other side is equal to the square root of 4a -a = sqrt 3A.
And then we get: the side opposite the 30 degrees over the other side over the hypotenuse is equal to 1: sqrt 3:2.
So it will be B, 5, 10, 5sqrt3
The set of values that could be the side lengths of a 30-60-90 triangle is (5, 10, 10√3). The answer is option D.
What is a triangle?A triangle is a closed two-dimensional geometric figure with three sides and three angles. It is the simplest polygon and is made up of three line segments that intersect at three points called vertices. The sum of the angles in a triangle is always 180 degrees.
In a 30-60-90 triangle, the side lengths are in the ratio:
1 : √3 : 2
So, if one side is x, then the other sides are x√3 and 2x.
Now, let's check the given sets of values:
A. (5, 5, √2, 10)
This set does not satisfy the ratio of the side lengths for a 30-60-90 triangle.
B. (5, 5, √3, 10)
This set does not satisfy the ratio of the side lengths for a 30-60-90 triangle.
C. (5, 5, 10, √2)
This set does not satisfy the ratio of the side lengths for a 30-60-90 triangle.
D. (5, 10, 10, √3)
This set satisfies the ratio of the side lengths for a 30-60-90 triangle, where the shortest side is 5, the longer leg is 5√3, and the hypotenuse is 10.
Therefore, the set of values that could be the side lengths of a 30-60-90 triangle is (5, 10, 10√3). The answer is option D.

Glen is making accessories for the soccer team. He uses 536.25 inches of fabric on headbands for 37 players and 2 coaches. He also uses 325.97 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answers
Answer:
For Headband
Each player used 13.75 inches of fabric
For Wristband
Each player used 8.81 inches of fabric
Step-by-step explanation:
Glen is making accessories for the soccer team.
For head bands :
He uses 536.25 inches of fabric on headbands for 37 players and 2 coaches.
Let the inches of fabric used be represented by x
536.25 = 37 x + 2x
536.25 inches = 39x
x = 536.25 inches/39
x = 13.75 inches of fabric.
For Wristbands
He also uses 325.97 inches of fabric on wristbands for just the players.
Let y represent the inches of fabric used for players
We have 37 players
Hence:
325.97 = 37y
y = 325.97 inches/37
y = 8.81 inches
Therefore:
For Headbands
Each player used 13.75 inches of fabric
For Wristbands
Each player used 8.81 inches of fabric

Answer:
[tex]t=\frac{4}{3} \\\\t=1.333333333333333....\\\\t=1\frac{1}{3}[/tex]
Step-by-step explanation:
A triangle's angles are always 180° total degrees.
The given triangle has the three little marks showing that the lengths are the same, so this means that the angles are also congruent. That means that the triangle is an equilateral triangle.
Set an equation where the given angle of F represents every angle and whose sum is 180°:
[tex](30t+20)+(30t+20)+(30t+20)=180\\\\3(30t+20)=180[/tex]
Solve for t. Use the distributive property:
[tex]90t+60=180[/tex]
Work to isolate the variable. Use inverse operations to cancel out the 60. Subtract 60 from both sides:
[tex]90t+60-60=180-60\\\\90t=120[/tex]
Use inverse operations to isolate t. Divide both sides by 90:
[tex]\frac{90t}{90} =\frac{120}{90} \\\\t=\frac{4}{3}[/tex]
The value of t is [tex]\frac{4}{3}[/tex].

Engineering=120+22x; Business=105-4x;Biology=98+6x; how many years will it be before Engineering has twice as many students as Business; how many years will it be before Engineering has twice as many students as Biology.
Answers
Answer:
Step-by-step explanation:
Given
Engineering=120+22x;
Business=105-4x;
Biology=98+6x;
If Engineering has twice as many student as biology then,;
120+22x = 2(98+6x)
Expand
120+22x = 196+12x
Collect like terms
120-196 = 12x-22x
-76 = -10x
x = -76/-10
x = 7.6
Hence it will take like 7 and a half years before engineering has twice as many student as biology
Lydia has 400$ in her bank account. Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account. Which inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300$ ?
Answers
Answer:
400 - 15x < 300
Step-by-step explanation:
We are told that she has 400$ in her bank account.
Now, Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account.
Total total withdrawal each week = 10 + 5 = $15
If number of weeks she has been withdrawing is x, then would have withdrawn $15x after x number of weeks.
Thus, amount left after x number of weeks is:
400 - 15x
We want to find the inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300.
Thus;
400 - 15x < 300
