B) a line segment that is congruent to a given line segment
C) a perpendicular bisector of a line segment
D) a line parallel to a given line through a point not on the line
Answer:
A) a line perpendicular to a given line through a point on the line.
Step-by-step explanation:
Perpendicular means at a 90 degree angle.

Each block in Ton's neighborhood is 2/3 mile long. If he walks 4 1/2 blocks,how far dose he walk?
Ton walks a total of 3 miles when he covers 4 1/2 blocks in his neighborhood, where each block is 2/3 mile long.
If Ton walks 4 1/2 blocks and each block in his neighborhood is 2/3 mile long, we can calculate the total distance he walks by multiplying the number of blocks by the length of each block. To find the distance Ton walks, you perform the following calculation:
First, convert the mixed number 4 1/2 into an improper fraction: 4 1/2 = (4 imes 2 + 1) / 2 = 9/2.
Multiply the improper fraction representing the blocks walked (9/2 blocks) by the fraction that represents the length of each block (2/3 mile): (9/2)imes (2/3) = 9/2 imes 2/3.
Simplify the multiplication by canceling out common factors: 9/2 imes 2/3 = (9 imes 2) / (2 imes 3) = 9/3 = 3 miles.
Therefore, Ton walks a total distance of 3 miles.

A computer password is to consist of 6 letters, none of which are used more than once. For security reasons, the letters Q and Z are not to be used in the first position. How many different passwords are possible?
The total number of possible 6-letter computer passwords, without repetition and with restrictions on the first letter, is 7,893,600.
Explanation:The question involves finding out the number of possible combinations for a 6-letter computer password where no letter is repeated and the letters 'Q' and 'Z' are not allowed in the first position.
For the first letter, we have 24 options (26 letters in the alphabet minus the two restricted letters, 'Q' and 'Z'). For the second letter, since the first letter has already been chosen and cannot be repeated, there are 25 options left. This pattern continues, reducing by one each time, leaving 24 options for the third, 23 for the fourth, 22 for the fifth, and 21 options for the sixth letter. The total number of possible passwords is calculated by multiplying all options together; hence, the answer will be 24 * 25 * 24 * 23 * 22 * 21.
The calculation yields a result of 7,893,600 possible passwords.
To find the number of different passwords possible, multiply the number of choices for each position: 24 * 25 * 24 * 23 * 22 * 21 = 39,825,600.
Explanation:To find the number of different passwords that are possible, we can break down the problem into steps:
First position: Since Q and Z cannot be used in the first position, there are 24 possible letters that can be used.Second position: Once the first position is determined, there are 25 letters remaining to be used in the second position (since Q and Z can now be used).Third position: There are 24 letters remaining to be used in the third position, since one letter has already been used in the first position.Fourth position: There are 23 letters remaining to be used in the fourth position.Fifth position: There are 22 letters remaining to be used in the fifth position.Sixth position: There are 21 letters remaining to be used in the sixth position.To find the total number of possible passwords, we multiply together the number of choices for each position: 24 * 25 * 24 * 23 * 22 * 21 = 39,825,600. Therefore, there are 39,825,600 different passwords that are possible.

Pedro buys 4 books at the fair for $7 each. Pedro hands the cashier 3 ten dollar bills. how much change would he receive? write an equation to solve. use c to represent the unknown.
The problem involves calculating the change received when Pedro buys four books at $7 each and pays with $30. The equation to solve this is c = $30 - $28. Therefore, Pedro receives $2 change.
Explanation:The subject of this question is a straightforward mathematics problem involving buying books and receiving change. We know that Pedro buys 4 books that each cost $7 and that he gives the cashier $30. To find out the change, represented as c , Pedro will get, we first figure out the total cost of the books: 4 books x $7 per book equals $28. Pedro pays with $30 so the calculation for the change would be: $30 (the amount Pedro paid) - $28 (the total cost of the books). This gives us the equation c = $30 - $28. Therefore, Pedro would receive $2 in change.

Pedro buys 4 books for $28 and pays with $30, so he would receive $2 in change. The equation to represent this is: c = $30 - $28.
To calculate the change Pedro receives, we can set up an equation where c represents the unknown change. Pedro buys 4 books at $7 each, so the total cost of the books is 4 books x $7/book = $28. He hands the cashier 3 ten dollar bills, which equals $30. The equation to find the change is then:
c = $30 - $28
Solving this equation, we get:
c = $2
So, Pedro would receive $2 in change after buying the books.

if g(x) = 2x-1 and h(x) = sqrt x find (g o h)(9)
Answer:
(g o h)(9) =5
Step-by-step explanation:
Given :[tex]g(x) = 2x-1[/tex]
[tex]h(x) = \sqrt{x}[/tex]
To Find: (g o h)(9)
Solution:
[tex]g(x) = 2x-1[/tex]
[tex]h(x) = \sqrt{x}[/tex]
To find (g o f)(x)=g(h(x))
[tex]g(h(x)) = 2\sqrt{x}-1[/tex]
Now substitute x = 9
[tex]g(h(9)) = 2\sqrt{9}-1[/tex]
[tex]g(h(9)) = 2(3)-1[/tex]
[tex]g(h(9)) = 6-1[/tex]
[tex]g(h(9)) = 5/tex]
(g o h)(9) =5
Hence the value of (g o h)(9) is 5
