A family is taking a picture, with everyone in the family standing in a row. In the family, there are two sets of twins. In how

Wittaler [7]

Answer:

376320.

Step-by-step explanation:

Given:

There are two sets of twins in a family.

Total family member = 9

Solution:

Let family members = AA BB C D E F G

<u>AA and BB are two set of twins .</u>

First of we will find the arrangements of 5 family member ( 9 - 4 = 5 )

No of ways 5 family member can seat = $^{5}P_{5}$

Now, we will find the arrangements of BB.

As given that nobody is sitting next to their twin, means A twins cannot seat together.

Therefore, they can seat in these blank places given below:

......B.......B......C......... D...... E........ F........ G.......... in $^{8}P_{2}$

Similarly, B twins cannot seat together.

Therefore, they can seat in these blank places given below:

......A.......A......C......... D...... E........ F........ G.......... in $^{8}P_{2}$

Total number of arrangements of all family members = $^{5}P_{5}$ $\times$ $^{8}P_{2}$ $\times$ $^{8}P_{2}$

$=\frac{5!}{5-5!} \times\frac{8!}{8-2!} \times\frac{8!}{8-2!}\\=\frac{5!}{0!}\times\frac{8!}{6!} \times\frac{8!}{6!}\\\\=5!\times\frac{8\times7\times6!}{6!} \frac{8\times7\times6!}{6!}$

$=5\times4\times3\times2\times1\times56\times56\\=376320$

Therefore, Total number of arrangements of all family members is 376320.

When working in the GreenHab, it takes me 120 minutes to report 20 tomato plants. How many plants can I report in 30 minutes?

Lyrx [107]

Answer:

Numbers of Tomato plants to be reported in 30 minutes = 5 unit

Step-by-step explanation:

It is given that ,

Time taken to report 20 Tomato plants (P1) = 120 minutes (T1)

Let number of plants to be reported in 30 minutes (T2) = P2

Now , $\frac{T2}{P2} = \frac{T1}{P1}$

$\frac{30}{P2} = \frac{120}{20}$

So, P2 = 5 unit

Hence the number of plant to be reported in 30 minutes = 5 unit Answer

Which of the given values is a solution to the equation 8c+3=−40c−10?

solniwko [45]

Answer:

$\boxed{\bold{C \ = \ \frac{-13}{48} \ or \ -0.27083333333}}$

Explanation:

8c + 3 = −40c − 10

[ Step 1: Add 40c to both sides ]

8c + 3 + 40c = −40c − 10 + 40c

48c + 3 = −10

[ Step 2: Subtract 3 from both sides ]

48c + 3 − 3 = −10 − 3

48c = −13

[ Step 3: Divide both sides by 48 ]

48c / 48 = −13 / 48

C = -13 / 48 or -0.27083333333
