Answer:
$121.82
Step-by-step explanation:
Okay, this is kind of complex, so let's go step by step.
First, we want to find the area of the rectangular lawn - we can do this by multiplying the length and width. The length is 100 and the width is 45 so 
m² is the area of the rectangle.
However, there are 3 ponds in which the grass seeds will not be going - so we need to find the area of all 3 of these circles and subtract it from 4500 (our rectangle area).
The area of a circle is represented by the formula 
The diameters are given here, which is double the radius, so to find the radius of each circle let's divide the diameters by 2.
First circle's radius: 
Second circle's radius: 
Third circle's radius: 
Now let's find the area of each circle.
<em>First Circle</em>: 
<em>Second Circle</em>: 
<em>Third Circle:</em> 
Adding all of these values gets us 412.125.
Now we can subtract from this from 4500 to get us 4087.875
If the grass seeds that cost £1.49 cover 50m² each, then we need 
bags.
Each bag costs £1.49, so the total cost is 
Hope this helped!!
2000+1400+1000+2300+1900=8600, so the answer would be about 8600 miles. Sorry, I couldn't see the picture if that is what it was. I did not see any multiple choices. If you can, comment the choices.
The logarithmic function when the temperature is 64 degrees is given as
ln f(x) = x ln 2.
<h3>
What is a logarithmic function?</h3>
A logarithmic function is the inverse of an exponential function. It is to be noted that all exponential functions can be written as logarithmic functions.
Hence, to convert the mathematical statement above into a logarithmic function we say:
f(x) = 2ˣ
ln f(x) = ln 2ˣ
ln f(x) = x ln 2
Ln 64 = x Ln 2
Let f(x) = 64;
Hence,
Ln 64 = x ln 2
Divide both sides by ln 2 to get x
ln 64/ln 2 = x
Hence,
x = ln 64/ln 2
= 6

Answer:
180 seconds is equal to 3 minutes because there is 60 seconds in a minute and 60 times 3 is 180
Step-by-step explanation:
So if it needs to be 180 seconds MORE than 3 minutes it would be 6 minutes
Answer:
log(2)
Step-by-step explanation:
property of logs says
Log(60) - Log(30) = Log(60/30) = Log (2)
