The total number of fungal spores can be found using an infinite geometric series where a1 = 8 and the common ratio is 4. Find the sum of this infinite series that will be the upper limit of the fungal spores.

Answers

Answer 1
Answer: The formula for infinite geometric series is equal to a1 / (1-r) where in this problem a1 is equal to 8 and r is equal to 4. In this case, r is not equal to less than 1. This means the sum should be infinity and cannot be determined definitely. 
Answer 2
Answer:

Answer:

This infinite geometric series is divergent and thus we cannot find the sum. The sum is infinity.


Step-by-step explanation:

There are two types of geometric series: convergent and divergent.

The sum of an infinite geometric sequence is given by the formula:

Sum = (a)/(1-r)

Where,

r is the common ratio and

|r|<1


If absolute value of r is NOT less than 1, then the series is divergent and sum cannot be found.

For our given problem, r=4 ,  clearly  |4|=4 , which is NOT less than 1, so the series is divergent and sum cannot be found.

How many pink beads are in Jadas storage box

Answers

The probability of getting a pink bead out of the storage box containing a sum total of 175 beads is 0.1428

As per the question statement, we are supposed to find the probability of getting a pink bead out of the storage box containing a sum total of 175 beads.

It is given that there are 25 pink beads in the storage box.

Probability = Favorable outcome / Total value

Probability = 25/175

Probability = 0.1428

Hence, the probability of getting a pink bead out of the storage box containing a sum total of 175 beads is 0.1428

  • Probability: The chances of happening or not happening of any event.

It takes 32 minutes for 3 people to paint 4 walls. How many minutes does it take 4 people to paint 7 walls?

Answers

we order these data:

32 minutes------------------------3 people------------------4 walls
x--------------------------------------4 people------------------7 walls
The minutes and the people are variables inversely proportional , therefore, we multiply in parallel
32 minutes*3 people=x*4 people

The minutes and the walls are variables directly proportinal; therefore, we  multiply cross.
32 minutes*7 walls=x*4 walls

Therefore:
32 minutes*3 people*7 walls=x*4 people*4 walls
x=(32 minutes*3 people*7 walls) / (4 people* 4 walls)
x=42 minutes.


Answer: the time will be 42 minutes.

Answer:

25 metres per second

Step-by-step explanation:

just divide 100 by 4 and you will get the answer.☺️☺️

Answer:

25 m/s

Step-by-step explanation:

train a travels at 12.5 m/s and will arrive at 100m in 7s.

train b arrives at the same distance, 100m, in 4s. so that means train b is going at 100m/4s and then simplify that

therefore train b is moving at 25m/s

The division property of equality could be used to solve which of the following equations?a. 5x= 30
b. x+ 3 = 7
c. (x+ 2) (x- 2) = 0
d. = 16

Answers

If you would like to know which of the above equations could be solved by the division property of equality, you can find this using the following steps:

a. 5 * x = 30     /5
    x = 30 / 5
    x = 6
b. x + 3 = 7      /-3
    x = 7 - 3 = 4
c. (x + 2) * (x - 2) = 0
    1. x = -2
    2. x = 2
d. = 16

The correct result would be a. 5 * x = 30 can be solved by the division property of equality.

Answer:

Option a is correct that is 5x=30 will use division property of equality.

Step-by-step explanation:

We have been given four different equations we need to tell which one could be used to solve by division property:

In Option a:

x can will be solved by division property

5x=30

5 will divide 30 on right hand side by the transformation rule which is

when multiplication is shifted to the other side of the equation it will be in division on the other side.

x=6

Therefore, option a is correct.


Convert 70% to a number when the whole is 150

use hundred n available positions,in this case 70 is the percentage and 150 is the whole so multiply the percent by hundered and then divide by 150 to get ur answer

What's this answer???

Answers

Youn could test all of the options by putting 8 and 3 in for a and b.

A.    a - b = 5
       8 - 3 = 5
            5 = 5

B.   a + b = 5
      8 + 3 = 5
            11 ≠ 5

C.   a - b = 8
      8 - 3 = 8
           5 ≠ 8

D.   a + b = 8
      8 + 3 = 8
            11 ≠ 8

As you can see, the only one that works is A. a - b = 5.
