in the taxi. Find the domain and range.
Answers
The situation is a function, & the independent and dependent variables are the number of miles and total fee, respectively
a. Does the situation represent a function? If so, identify the independent and dependent variables.The given parameters are
Initial Fee = $2.80
Rate = $3.50 per mile
Let the number of miles be x and the total fee be y
So, we have
Total fee = Initial Fee + Rate * Number of miles
This gives
y = 2.8 + 3.5x
This means that the situation is a function, & the independent and dependent variables are the number of miles and total fee, respectively
b. You have enough money to travel at most 20 miles in the taxi. Find the domain and range.Here, we have
Maximum number of miles = 20
This means that the domain is 0 <= x <= 20
Substitute 20 for x in y = 2.8 + 3.5x
y = 2.8 + 3.5 x 20
Evaluate
y = 72.8
This means that the range is 0 <= x <= 72.8

The best statement and reason that completes the proof is option D that is,
statement- 2. ∠1 is supplementary to ∠2
reason- 2. linear pair theorem
To prove ∠1 ≅ ∠ 3, we can use the congruent supplements theorem. According to the congruent supplements theorem, If two angles are supplements of the same angle then two angles are congruent.
Line a and line b intersect (given)
∠3 is supplementary to ∠2 because of linear pair theorem (given)
So, if we take ∠2 as the common angle
And ∠1 is supplementary to ∠2 by linear pair theorem ( option D)
Then, ∠1 is supplementary to ∠2 which is supplementary to ∠3
Therefore, ∠1 ≅ ∠3 (according to the congruent supplements theorem)
Hence proved.

Option D, which is the following, is the finest statement and justification for concluding the proof.
statement 2. 1 is an addition to 2
2. The linear pair theorem
We can apply the congruent supplements theorem to demonstrate 1 and 3. The congruent supplements theorem states that two angles are congruent if they are supplements of the same angle.
Lines a and b come together (given)
Because of the linear pair theorem, 3 is an addition to 2 (given)
Thus, if we consider 2 to be the common angle
And the linear pair theorem enables 1 to be an addition to 2 ( option D)
Then, 1 is an addition to 2 which is an addition to 3
Consequently, 1 + 3 (according to the congruent supplements theorem)
So it was proved.

According to a recent survey, 62 % of the population owns a cat. 37 Percent of cat owners are married, while 44 % of non-cat owners are married. If you randomly select a person, what is the probability that she/he is married?
Answers
Answer:
There are two possibilities that you need to take into account:
1) having a cat and being married
2) not having a cat and being married
P(having a cat) = 0.19
P(no cat) = 1 - P(having a cat) = 1 - (0.19) = 0.81
Since 9% of cat owners are married: (0.19)(0.09) = 0.0171
Since 11% of non-cat owners are married: (0.81)(0.11) = 0.0891
Probability of randomly selected person being married = 0.0171 + 0.0891 = 0.1062

A department store advertises a sale where the customer chooses the discount. A customer may choose a flat discount of $20 off any purchase or 20% off the total purchase price. The final purchase price of an item was $175.
a. What are the possible prices of the item before each discount?
b. Which discount represents a bigger savings in cost for the customer?
Answers
The answers will be :
A. The possible prices at flat discount of $ 20 will be $195 and at flat discount of 20% will be $218.75
B. The discount of flat 20 % gives a bigger savings in cost for the customer.
What do you mean by discount ?
The discount is the difference between the purchase price and the item's par value or simply deduction from the cost price of a good.
It is given that the final purchase price of the item is $175.
A.
Let's try to find out the possible price of item before each discount.
So , price before discount can be calculated by using formula which is :
Price before discount = Discount + Final purchase price
As in first case the flat discount is of $20 , so :
Price before discount = $20 + $ 175
Price before discount = $195
Now as per the question , there is a flat discount of 20% off the total purchase price .
So , let's assume if price before discount is P then :
[ P - ( 20P / 100) ] = 175
P - 0.2 P = 175
0.8 P = 175
or
P = $ 218.75
B.
From the above calculations which we have done , we can conclude that the discount of 20 % represents a bigger savings in cost for the customer because customer is saving an amount of $218.75 which is greater than $195.
Therefore , the answers will be :
A. The possible prices at flat discount of $ 20 will be $195 and at flat discount of 20% will be $218.75
B. The discount of flat 20 % gives a bigger savings in cost for the customer.

All you have two unmarked cups 6 ounces and 10 ounces respectively how can you use the two cups to obtain exactly 8 ounces of liquid in the 10 ounce cup
Answers
I don’t know the rules but here it goes.
I would fill up the 10-oz glass with liquid and use it to fill the 6-oz glass.
Now I have 4-oz left in the 10-oz glass.
Empty the liquid from the 6-oz glass and pour the 4-oz remaining from the 10-oz glass to the 6-oz glass.
Now I have 4-oz.
Then, I would fill up the 10-oz glass again and use it to fill up the 6-oz glass that has 4-oz in it.
There are 4 oz in the glass already, so I can only add 2-oz more.
10 oz minus 2 oz = 8 oz left in the 10-oz glass.
