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!!
The largest triangle and the triangle whose hypotenuse is x are similar. So:
(21 + 4)/x = x/4
Cross multiply:
x^2 = 100
x = 10
Your answer is incorrect. It should be 10, not 20.
Hi!
Slope intercept form is in the form y=mx+b
m is the slope, and that is given so we can plug that into the equation
y = -5x + b
We are also given the y-intercept (0,2) and we can plug that into the equation as well, to find b
2 = 5(0) + b
2 = b
So now that we know both m and b, plug only those two into the equation.
y = -5x + 2
That is your equation

Answer:
-2
Step-by-step explanation:
From the position of 2 on the x axis, just trace down to the graph.
Where the trace intersects the graph, then trace this point to the y-axis
This gives -2
