Answer:

24 pages

Step-by-step explanation:

It is given that;

72 pages : 3 hours

One must solve for the unit rate of, how many pages per hour. This can be done by dividing both sides of the equation by 3, that way the unit for the parameter (hours) will be reduced to one. Thus, one gets the answer to the question.

72 pages : 3 hours\\/3\\\\24pages : 1 hour

Regarding your (1/10 divided by 2/5):  I'm going to regard this as

(1/10) divided by (2/5).  

First, write 

 1
---         
10

Invert the fraction 2/5 and then multiply 1/10 by 5/2:

1(5)
-------- = 1/4, after reducing  5/10.
10(2)

Thus, <span>−34+(1/10÷2/5) yields -34 + 1/4, or   -33 3/4.</span>

Help.... and thanks
Archy [21]

Answer:

π

Step-by-step explanation:

The *period* of a function is the length it takes before it repeats. Usually, the period of the sine function is 2π; it takes a full rotation around the unit circle for it to repeat. When we replace the input x with -2x, this does a few things:

- Changes the rotation direction

- Makes the rotation go twice as fast

If we rotate around the unit circle twice as fast, it’ll take us half of 2π, or just π to complete a cycle.

Answer:

number of $20 bill = 4

Number of $5 bill = 5

Step-by-step explanation:

Given that:

Total number of $5 and $20 bills = 9

Let :

Number of $5 bills = x

Number of $20 bills = y

Combined worth of all bills = $105

x + y = 9 - - - (1)

5x + 20y = 105 - - - (2)

From (1)

x = 9 - y

Substitute x = 9 - y into (2)

5(9 - y) + 20y = 105

45 - 5y + 20y = 105

15y = 105 - 45

15y = 60

y = 60/15

y = 4

x = 9 - y

x = 9 - 4 = 5

Hence,

number of $20 bill = 4

Number of $5 bill = 5
