The relationship of the angles are:
1. ∠5 and ∠6 are linear pairs.
2. ∠3 and ∠2 are vertically opposite angles.
3. ∠4 and ∠8 are corresponding angles.
Given that,
In the picture there are parallel lines with a transversal.
We have to find the relation between,
1. ∠5 and ∠6?
2. ∠3 and ∠2?
3. ∠4 and ∠8?
Take the 1st angles.
∠5 and ∠6 are linear pairs.
A linear pair of angles is formed when two lines intersect at a single point. If the angles follow the spot where the two lines come together in a straight line, they are said to be linear. In a pair of linear equations, the sum of the angles is always 180°.
Take the 2nd angles.
∠3 and ∠2 are vertically opposite angles.
When two straight lines collide at a particular vertex, they create angles that are perpendicular to one another vertically. Angles that are perpendicular to one another vertically are equal. These are occasionally referred to as vertical angles.
Take the 3rd angles.
∠4 and ∠8 are corresponding angles.
The angles that meet two other straight lines in the same vicinity. If the two lines are parallel, the comparable angles are also equal.
Therefore, The relationship of the angles are:
1. ∠5 and ∠6 are linear pairs.
2. ∠3 and ∠2 are vertically opposite angles.
3. ∠4 and ∠8 are corresponding angles.

How many gallons each of 25% alcohol and 10% alcohol should be mixed to obtain 15 gal of 21% alcohol?Gallons ofPure AlcoholGallons ofSolutionХy15Percent(as a decimal)25% = 0.2510% = 0.121% =How many gallons of 25% alcohol should be in the mixture? gal
Answers
Answer
11 gallons of the 25% alcohol is required for the mixture.
4 gallons of the 10% alcohol is required for the mixture.
Explanation
Let the number of gallons of 25% alcohol required be x
Let the number of gallons of 10% alcohol required be y
The total amount of gallons required is 15 gallons. In mathematical terms,
x + y = 15
The alcohol content of the 15 gallons is to be 21%.
21% of 15 gallons = 3.15 gallons
From the first statements,
Let the number of gallons of 25% alcohol required be x
Let the number of gallons of 10% alcohol required be y
25% of x gallons = 0.25x gallons
10% of y gallons = 0.10y gallons
0.25x + 0.10y = 3.15
We can then bring these two equations together to solve simultaneously
x + y = 15
0.25x + 0.10y = 3.15
Solving this simultaneously with the calculator, we obtain
x = 11 gallons
y = 4 gallons

Quinn needs to collect at least 90 toys for a toy drive to earn community service credit. He has already collected 16 toys.
Answers
Let's define the next variable:
t: number of toys that Quinn still needs to collect
The number of toys that he already collected plus the number of toys that Quinn still needs to collect is: 16 + t
Quinn needs to collect at least 90 toys, then 16 + t must be greater than or equal to 90, that is,
16 + t ≥ 90
or
90 ≤ 16 + t
Subtracting 16 at both sides, we get:
90 - 16 ≤ 16 + t - 16
74 ≤ t
A plane flew 1225 mi in 5 hr with the wind. It would take 7 hr to travel the same distance against the wind. What is the speed of the plane in still air and the speed of the wind?
Answers
Answer:
wind speed 35 miles per hour
plane speed 210 miles per hour
Explanation:
Let us call p the place speed and w the wind speed.
We know that
p + w = 1225/5 = 245
p - w = 1225/7 = 175
adding the two equations above gives
2p = 245 + 175
2p = 420
dividing both sides by 2 gives
p = 210 miles per hour.
putting in the value of p in p + w = 245 gives
210 + w = 245
w = 245 - 210
w = 35 miles per hour

enter the value of y for which LMNO must be a parallelogram
Answers
In a parallelogram, opposite sides are equal.

OL = y-6
NM= 1/3 x
ON= 5x-8

First, solve for x
ON = LM
5x - 8 = 9x - 26
-8 + 26 = 9x - 5x
18 = 4x
18/4 = x
x = 4.5
Replace x=4.5 on NM, and solve for y:

Determine the value of k for which the inequality $0.5<-4x+k\le12-k$ has the solution set $\left\{x|1.25\le x<2\right\} Need the answer ASAP.
Answers
The value of k for which the inequality has the given solution set is:
k = 8.5.
How to obtain the value of k?The inequality is presented as follows:
0.5 < -4x + k ≤ 12 - k.
Two inequalities compounded, hence the and operation is applied, which means that the solution set is composed by the elements that respect both conditions.
The solution set of the inequality is:
1.25 ≤ x < 2.
The lower bound of the solution is of 1.25, hence:
-4x + k ≤ 12 - k.
-4x + 2k ≤ 12
4x ≥ 2k - 12
x ≥ 0.5k - 3
Hence:
0.5k - 3 = 1.25
0.5k = 4.25
k = 4.25/0.5
k = 8.5.
The upper bound of the solution is of 2, hence:
-4x + k > 0.5
-4x > 0.5 - k
x < -0.125 + 0.25k
Hence:
-0.125 + 0.25k = 2
k = 2.125/0.25
k = 8.5. -> Which confirms the solution.

In order to solve the previous equation, proceed as follow:
4x - 3 = 2x + 5 subtract 2x both sides
4x - 2x - 3 = 5 add 3 both sides
4x - 2x = 5 + 3 simplify like terms
2x = 8 divide by 2 both sides
x = 8/2
x = 4

you have a job wich pays double time when working more than 40 hours a week. last week you worked 55 hours and earned $840. what is your regular pay rate?
Answers
Explanation
The salary with regular pay rate is calculated as:
[tex]S_{\text{regular}}=R\times h[/tex]S is the salary, R is the regular pay rate and h is the number of hours worked.
The salary with over time is:
[tex]S_{\text{overtime}}=2\text{Rxh}_{\text{overtime}}[/tex]Because it pays double after 40 hours.
So the first 40 hours worked you'll get
[tex]S_{\text{regular}}=40R[/tex]The amount of overtime hours is 15 (55-40 = 15), so the overtime salary is:
[tex]S_{\text{overtime}}=2R\times15=30R[/tex]The total Salary is the sum of the regular and the overtime salaries:
[tex]S=S_{\text{overtime}}+S_{\text{regular}}[/tex]If the total salary was $840, then the regular pay rate R is:
