No not all diagonal lines are lines of symmetry! Because if you take a piece of notebook paper and fold it in half the side do not match up! hope this helps :)

No, they are not. Here's an example.

The image attached is a hexagon. All of the lines drawn in are some of the diagonals. The diagonal with the arrow, however, is not a line of symmetry. Therefore, not all diagonals are lines of symmetry.

if an office of 36 typist uses 12 dozen envelopes per day how many dozen envelope would an office of 125 typists of use?

Pani-rosa [81]

Assuming the envelope consumption is proportional to the number of typists, you have ...
(12 dz)/36 = x/125
125*(12 dz)/36 = x = 41 2/3

An office of 125 typists would use 41 2/3 dozen envelopes per day.

Write an inequality to represent the phrase: the difference of a number and 9 is no more than 95

Sliva [168]

Answer:

$x-9\leq 95$

Step-by-step explanation:

Let

x ----> the number

we know that

The phrase " the phrase: the difference of a number and 9" is equal to

subtract the number 9 from the number x

(x-9)

The phrase" no more than 95" means "less than or equal to 95" (≤95)

The inequality that represent this situation is

$x-9\leq 95$

William and his three friends went out for lunch. The bill was $34 and they left a 15% tip. They want to split the bill equally.

slavikrds [6]

Answer:

Each person will pay $9.78

Step-by-step explanation:

Given that:

Amount of bill = $34

Tip = 15%

Amount of tip = $\frac{15}{100}*34$

Amount of tip = 0.15 * 34

Amount of tip = $5.10

Amount after bill = 34 + 5.10 = $39.10

Number of people = William + three friends = 4

Per person share = $\frac{39.10}{4}$

Per person share = $9.775

Rounded to two decimal places

Per person share = $9.78

Hence,

Each person will pay $9.78

Two functions, P and Q, are described as follows: Function P y = 5x + 3 Function Q The rate of change is 2 and the y-intercept i

Svetach [21]

Function P . . . . . y = 5x + 3

Function Q . . . . . y = 2x + 4

Function P rate of change = 5
Function Q rate of change = 2

The first one is => 3 <= more than second one.
