Rashid can do a piece of work in 8 days, which Tipu can finish in 12 days. If they work at it on alternate days with Rashid beginning, in how many days, the work will be finished?
Answer:
The work will be finished in 10 days.
Step-by-step explanation:
Rashid can do a piece of work in 8 days
This means that each day he works, Rashid does [tex]\frac{1}{8}[/tex] of the work.
Tipu can finish in 12 days.
This means that each day he works, Tipu does [tex]\frac{1}{12}[/tex] of the work.
Each 2 days:
Each 2 days they work, the amount done is given by:
[tex]\frac{1}{8} + \frac{1}{12} = \frac{3 + 2}{24} = \frac{5}{24}[/tex]
Each 2 days, 5/24 of the work is done:
The number of periods of 2 days that is needed to finish the work(100% = 1 completed), is given by:
[tex]d = \frac{1}{\frac{5}{24}} = \frac{24}{5} = 4.8[/tex]
2*4.8 = 9.6
Rounding up
The work will be finished in 10 days.

Answer:

Step-by-step explanation:
3(x-2)+9=3x+20 pls solve fully
Result:
[tex]0=17[/tex]
The input is a contradiction: it has no solutions
Step-by-step explanation:
Distribute:
[tex]3(x-2)+9=3x+20[/tex]
[tex]3x-6+9=3x+20[/tex]
Add the numbers:
[tex]3x[/tex][tex]-6+9=3x+20[/tex]
[tex]3x+3=3x+20[/tex]
Subtract [tex]3[/tex] from both sides of the equation:
[tex]3x+3=3x+20[/tex]
[tex]3x+3[/tex][tex]-3=3x+20[/tex][tex]-3[/tex]
Simplify:
Subtract the numbers:[tex]3x+3[/tex][tex]-3=3x+20-3[/tex]
[tex]3x=3x+20-3[/tex]
Subtract the numbers:[tex]3x=3x+20[/tex][tex]-3[/tex]
[tex]3x=3x+17[/tex]
[tex]3x=3x+17[/tex]
Subtract [tex]3x[/tex] from both sides of the equation:
[tex]3x=3x+17[/tex]
[tex]3x[/tex][tex]-3x=3x+17[/tex][tex]-3x[/tex]
Simplify:
Combine like terms:[tex]3x[/tex][tex]-3x=3x+17-3x[/tex]
[tex]0=3x+17-3x[/tex]
Combine like terms:[tex]0=-3x+17[/tex][tex]-3x[/tex]
[tex]0=17[/tex]
[tex]0=17[/tex]

Answer:
the answer is simply 17/24
Answer:
The first option [tex]\frac{17}{21}[/tex]
Step-by-step explanation:
In order to solve this question we have to add the three fractions. In order to add the fraction we need them to have the least common dinoinator. For 3, 7, and 21 it is 21. So...
[tex]\frac{2}{3} - \frac{4}{7} + \frac{15}{21} = \frac{14}{21} - \frac{12}{21} + \frac{15}{21} = \frac{17}{21}[/tex]

There are 20 books in 4 boxes. How many books are there in 1 box?
Answer:
There are 5 books in 1 box
Step-by-step explanation:
It is quite easy to solve. You have to use division to figure out how many books go in each box. Our division equation will be: 20 ÷ 4 = ?
We will divide 20 by 4 and our answer is 5.
We can double-check our answer by doing multiplication. 5 x 4 = 20, leading us back to the original 20 books that are in boxes.
So, there are 5 books in each box.

Given:
Quadrilateral IJKL is similar to quadrilateral MNOP.
To find:
The measure of side NO.
Solution:
If two figures are similar, then the corresponding sides are similar.
Quadrilateral IJKL is similar to quadrilateral MNOP. So,
[tex]\dfrac{IL}{MP}=\dfrac{JK}{NO}[/tex]
Putting the given values, we get
[tex]\dfrac{9}{35}=\dfrac{16}{NO}[/tex]
[tex]9\times NO=16\times 35[/tex]
[tex]9NO=560[/tex]
Divide both sides by 9.
[tex]NO=\dfrac{560}{9}[/tex]
[tex]NO=62.222...[/tex]
[tex]NO\approx 62.2[/tex]
Therefore, the measure of side NO is 62.2 units.
