Answer:
25.) Slope of AB = 5
Slope of CD = -1/5
Perpendicular
26.) Slope of EF = -3/5
Slope of GH = -3/5
Parallel
Step-by-step explanation:
Use this formula to find slope. [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Parallel lines have the same slope
Perpendicular lines have the opposite reciprocal and sign
25.)
Plug in AB slope is 5
2 - 7/ 3 - 4 = -5/-1 = 5
Plug in for CD slope is -1/5
3 - 4/ 2 - -3 = -1/5 = -1/5
The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.
26.)
Plug in EF slope is -3/5
1 - 4/ 3 - -2 = -3/5 = -3/5
Plug in GH slope is -3/5
-5 - -2/ 4 - -1 = -3/5 = -3/5
The lines EF and GH are parallel lines because they have the same slopes.
Hope this helps ya!

Which table does NOT show direct variation?
Answer:
Tables 3. The one in the bottom left corner.
Step-by-step explanation:
The values of table C is not in variation.
What is variation?Two sorts of quantities typically exist in a mathematical equation when a relationship is established for a certain type of parameter. One is a constant that stays the same regardless of how the other variables in the equation vary, and the other is a variable that changes depending on the circumstances. Variation is the term used to describe the changing of variables.
Given tables,
A direct variation is a straightforward relationship between x and y. To find a direct relationship, either use the formula y = kx or divide y over x (y/x).
Relation for table A
y /x = -3/1 = -3
y /x = -9/3 = -3
y /x = -18/6 = -3
y /x = -36/12 = -3
relation is in variation.
Relation for table B
y /x = 3/1 = 3
y /x = 9/3 = 3
y /x = 18/6 = 3
y /x = 36/12 = 3
relation is in variation.
Relation for table C
y /x = 4/1 = 4
y /x = 6/3 = 2
y /x = 9/6 = 3/2
y /x = 15/12 = 5/3
Equation doesn't have a direct relationship between x and y.
Relation for table D
y /x = 2/1 =2
y /x = 6/3 = 2
y /x = 12/6 = 2
y /x = 24/12 = 2
relation is in variation.
Hence the table C is not in variation.

A car dealership sold 84 cars in April. The dealership wants to increase the number of cars sold by 25% in May. How many cars will the dealership need to sell to reach their goal?
Answer: 105 Cars
Step-by-step explanation: To get an increase of 25% you need to multiply 84 by .25 then add the product of that to 84 to get 105
The number of cars dealership need to sell to reach their goal is, 105 cars
What is the percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
Given that,
A car dealership sold 84 cars in April,
The dealership wants to increase the number of cars sold by 25% in May
The number of cars dealership need to sell to reach their goal = ?
This represents a 25% increase, which is the same as adding one quarter to the original number of cars sold.
The car dealership wants to increase the number of cars sold by 25% in May, which means that they want to sell,
⇒ 84 x 1.25 = 105 cars
So, the dealership will need to sell 105 cars in May in order to reach their goal of increasing the number of cars sold by 25%.

Answer:
45 miles
Step-by-step explanation:
Use the Pythagorean Theorem. Imagine a line connecting the ends of the right angle you made by driving. It would make a right triangle. You are trying to find the hypotenuse. Use the formula [tex]a^{2} +b^{2} =c^{2}[/tex]. Square 27, or multiply 27 by 27, to get 729. Add this to the square of 36, 1296. So [tex]c^{2}[/tex] = 2025. Find the square root of 2025. [tex]\sqrt{2025}[/tex] = 45. Hope this helped ^^

Directions; Write a system of equations for each of the descriptions below, and then solve the systems. Hint: you can graph the equations to find the solutions.
There is a number that is three-fifths the total of the other number. When four is added to one of the numbers their sum will be equal to the other number. There are two pairs of numbers that satisfy these descriptions. What are they?
Answer:
6 and 10
Step-by-step explanation:
Let a = the first number(3/5 of the second number namely b)
Let b = the number that is 5/3 of a
a=3/5 b
Assuming they are both positive integers, obviously you will have to add 4 to a.
4+a = b
4 + 3/5 b = b
2/5 b = 4
b = 10
a=6

1. ADEA has vertices D(8,4), E(2, 6), and F(3, 1). What are the vertices of the image after a dilation with a scale factor of 5 using the origin as the center of dilation? TO
Answer:
The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)
Step-by-step explanation:
If the point (x, y) dilated by a scale factor k using the origin as a center of dilation, then its image is (kx, ky)
Let us use this rule to solve our question
∵ The vertices of ΔDEF are D (8, 4), E (2, 6), and F (3, 1)
∵ ΔDEF dilated by a scale factor 5
∴ k = 5
∵ The origin as the center of dilation
→ That means, multiply the coordinates of every point by 5
∴ D' = (8 × 5, 4 × 5)
∴ D' = (40, 20)
∴ E' = (2 × 5, 6 × 5)
∴ E' = (10, 30)
∴ F' = (3 × 5, 1 × 5)
∴ D' = (15, 5)
∴ The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

The cookies in a jar contain a total of 1000 chocolate chips. All but one of these cookies contains the same number of chips; it contains one more chip than the others. The number of cookies in the jar is between one dozen and three dozen. What is the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip? (Hint: using factorization) (A) 65 (B) 64 (C) 63 (D) 66 (E) 67
Answer:
65
Step-by-step explanation:
From the given information:
Let consider p to be the total numbers of the cookies
If there are 1000 chocolate chips in the jar;
The number of chocolate chips if we remove one chocolate chips = 1000 -1
= 999
The number of available choco chips on each cookie except for the one having an extra chocolate chip = 999/p
Thus, to achieve a whole number, p is required to be a factor of 999
By factorization of 999, we get:
36 > p > 12; Thus, the value for "p" lies between 36 and 12, and which must be by 999 is 27
Thus, the number of cookies in the jar "p"= 27
However, the number of chocolate chips on with the extra chocolate chip
= 999/p + 1
= 999/27 + 1
= 37 + 1
= 38
Thus, the sum of the number of cookies in the jar + the number of chocolate chips on with the extra chocolate chip
= 27 + 38
= 65

Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets. Manny would like a mixture of 60 detergent and 40% water in a 5 gallon buckets. To make this he combined some 80/20 mixture with some pure water in each 5 gallon bucket. How much gallons of pure water does Manny add to each 5 gallon bucket.
Answer:
1.67 gallons
Step-by-step explanation:
Given that:
Original mixture contains 80% detergent and 20% water in a 15 gallon bucket.
New Mixture to contain 60% detergent and 40% water of 5 gallon bucket.
To find:
Volume of Pure water to be added to each 5 gallon bucket to obtain the new mixture.
Solution:
First of all, let us calculate the answer by adding pure water to 15 gallon bucket.
Let the number of gallon of water to be added = [tex]x[/tex]
New volume = (15+[tex]x[/tex]) gallons
Now, let us compare the number of gallons of water in the mixture before and after.
[tex]15\times 20\% + x = (15+x)\times 40\%\\\Rightarrow (3+x)\times 5 = (15+x)\times 2\\\Rightarrow 15+5x=30+2x\\\Rightarrow 3x=15\\\Rightarrow x =5\ gallons[/tex]
Therefore, to a 15 gallon bucket (80% detergent and 20% water)of detergent mixture, if we add 5 gallons of pure water , it will become 60% detergent and 40% water.
To a 5 gallon bucket, the number of gallons of water to be added = [tex]\frac{5}{3} =\bold{1.67\ gallons}[/tex]

The Pasadena High school biology club is planning a trip to Yosemite National Park. The trip will cost $300 per club member plus and $800 deposit. Which of the following graphs models the total average cost of the trip per club member?
Answer:
Answer: D (the last graph)
Step-by-step explanation:
In this item, we are given that each student is to pay an amount equal to $300 on top of the $800 that is assumed to be divided by the total number of students who will join the field trip. In this case, the more number of students, the lesser would be the amount the student will pay from the deposits.
If there are infinite number of students, one student will partake almost $0 in the deposit. The answer to this item therefore is the last graph.
