A radio station spends 1/40 of each 24 hours on public service announcements. How much time is spent on public service announcements each day?

Answers

Answer: They spent 0.6 hours =36 minutes on public service announcements each day.

Step-by-step explanation:

Since we have given that

Number of hours in a day = 24 hours

Fraction of hour a radio station spends on public service announcements = $(1)/(40)$

So, Number of hours spent on public service announcements each day would be

$(1)/(40)* 24\n\n=(24)/(40)\n\n=0.6\ hours$

As we know that

1 hour = 60 minutes

0.6 hours = 0.6×60 = 36 minutes

Hence, they spent 0.6 hours = 36 minutes on public service announcements each day.

Start by calling the time spend on announcements 'A'. We can then set up an equation to represent the problem:

$A=24hours * (1)/(40)$

and then solve by multiplication to get:

A=0.6hours

We could also convert this into minutes:

$A=0.6hours * (60mins)/(1hour) = 36mins$

A wooden board 100 centimeters long is cut into two pieces.One piece is 16 centimeters longer than the other. What are the lengths of the two pieces?

Answers

legnth are x and y
x+y=100

one is 16 more than other
x is 16 more than y
x=16+y

x=16+y therefor we can put 16+y for x
(16+y)+y=100
16+y+y=100
16+2y=100
minus 16 both sides
2y=84
divide by 2
y=42

sub back
x=16+y
x=16+42
x=58

the legnsh are
42 cm and 58cm

One piece is 66 cm and the other piece is 34 cm

Name four fractions whose
values are between 1/7 and 1/5

Answers

Answer:

21/140, 22/140, 23/140, 24/140

Step-by-step explanation

7 and 5 have a common multiple of 140.

140/7 = 20 , 20/140

140/5 = 28, 28/140

21, 22, 23, 24, 25, 26, and 27 are all numbers between 20 and 28.

Final answer:

Four fractions that fall between 1/7 and 1/5 are 2/14, 3/21, 4/28 and 5/35. These fractions simplify to 1/7 when simplified but can serve as a reference. You could also use fractions like 2/13, 2/12, 2/11, and 2/10, which all fall between 1/7 and 1/5.

Explanation:

To find four fractions whose values are between 1/7 and 1/5, we can increase the denominator while keeping the numerator constant or slightly increase the numerator. Some examples include 2/14, 3/21, 4/28, and 5/35. Let's analyze these:

In fraction 2/14, if we simplify it, we get 1/7. This is not strictly between 1/7 and 1/5 but is a good starting point.
In fraction 3/21, if we simplify it, we get 1/7. This is not strictly between 1/7 and 1/5 but it's a good reference.
Next, we have 4/28 which simplifies to 1/7. Again, it's not strictly between, but it's a good reference.
Finally, we have 5/35. This simplifies to 1/7, it's not strictly between, but it's a good reference.

Please note that you could also find fractions by increasing the numerator slightly, such as 2/13, 2/12, 2/11, and 2/10 where all these fractions will lie between 1/7 and 1/5.
