Given;
6Ln (x + 2.8) = 9.6 

We will transpose 6 in the Ln, so that we will leave Ln alone.
Ln (x + 2.8) = 9.6/6 = 1.6 

we divide the 9.6 to 6 and we get 1.6

x + 2.8 = e^1.6 
e^ for the substitution of Ln

x = e^1.6 - 2.8 
insert the e^(1.6) in the calculator and you will get 4.95303242439511 and subtract 2.8 and you will get the answer.

x = 2.153 
2.153 is the final answer in this question.

I think the answer is 80 because I’m point 2 it’s is 40 and in point 3 is 60 and in point 5 is 100 so I am guessing each goes by 20 so what is between 60 and 100 if you can’t by 20s would be 80 I don’t know if I am correct tho

A square park has an area of 6561 square meters. If you walk around the park what is the distance that you would have walked?
Paraphin [41]
First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a   ==>  A=a^2 where a is length of the side.
From this formula we can find
a= \sqrt{A}
a=\sqrt{6561} =81 - 1 side
Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer

Gardener has 780 plants. He wants to plant there in such a way that the number of rows and the numbers of columns remains same.
AleksAgata [21]

Answer:

<em>Gardener will need 4 more plants.</em>

Step-by-step explanation:

Gardener has 780 plants and wants to plant them in an array of n rows and n columns.

The number of plants needed to do that is:

n*n=n^2

He actually has 780 plants, thus it should occur:

n^2=780

Taking the square root:

n=27.9

Since n needs to be an integer, we round up n to get

n=28

But 28^2=784, 4 more than the actual number of plants, thus:

Gardener will need 4 more plants.

Note: There are other possible results for n. If we set n=29, then n^2=841 and Gardener would need 841-780=61 more plants, but the question asked for the minimum number of plants.
