First generation: 3

Second generation: 3\times2.2

Third generation: 3\times2.2\times2.2=3\times2.2^2

Fourth generation: 3\times2.2\times2.2\times2.2=3\times2.2^3

And so on. The general formula for the nth generation is 3\times2.2^{n-1}. So by the 15th generation, you should expect around 3\times2.2^{15-1}\approx186655 geese.

50 POINTS<br><br>Need help with these 3 questions. ​
mr_godi [17]

Answer:

1st: 1/x (6mins). 2nd: 12. 1 day.

Step-by-step explanation:

1st:

One person can do a certain job in ten minutes, and another person can do the same job in fifteen minutes. How many minutes will they take to do the job together?

One person's rate:: 1/10 job/hr

Other person's rate:: 1/15 job/hr

Together rate:: 1/x job/hr

If x represents how many minutes to do the job together, then how much of the job does the slowest person do? 6 minutes.

-------------------

2nd:

Given : The sum of one-third of a number and three-fourths of the number exceeds that number by one.

To find : Which equation could be used to find the number

Let a number  = n

One third of a number = .

Three - fourths of the number  =  .

Sum of their is  exceeds that number by one.

+  = n +1.

Taking common denominator

= n+1 .

= n+1.

On subtracting n both sides.

-n = 1

Taking common denominator

= 1

= 1

On multiplying by 12 both sides

n= 12.

-------------------

3rd:

Person A can finish job in 6 days

Person B can finish job in 2 days

Person C can finish job in 3 days.

So let us present it this way.

x/6 + x/2 + x/3 = number of days

Find common denominator which is 6.

x/6 +3x/6 + 2x/6 = days

6x/6 = days

x = 1 day.

Quadrilateral abcd is inscribed in a circle. M angle C is 64 degrees, M angle B is (6x+4) degrees, M angle C is (9x-1) degrees.
djverab [1.8K]
We are given that angle C is (9x - 1) degrees, and that this is equal to 64 degrees. Therefore,
9x - 1 = 64
9x = 65
x = 65/9
This means that angle B is (6x + 4) = 6(65/9) + 4 = 47 and 1/3 degrees.
In a cyclic quadrilateral, opposite angles add up to 180 degrees, so angle D + angle B = 180
angle D = 180 - angle B
angle D = 180 - (47 1/3)
angle D = 132 2/3 degrees
