Answer:
Hey there!
For this question, we write a proportion.
![\frac{40}{0.6}=\frac{250}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B0.6%7D%3D%5Cfrac%7B250%7D%7Bx%7D)
![40x=150](https://tex.z-dn.net/?f=40x%3D150)
![x=3.75](https://tex.z-dn.net/?f=x%3D3.75)
Thus, the nurse to give the patient exactly 3.75 ml of the solution.
Let me know if this helps :)
Answer:
is = 92
Step-by-step explanation:
To answer this question substitute n = 10 in the formula of the given equation.
So, we have
![a_n = 10n - 8\\a_{10} = 10*(10) - 8\\a_{10} = 100 - 8\\a_{10} = 92](https://tex.z-dn.net/?f=a_n%20%3D%2010n%20-%208%5C%5Ca_%7B10%7D%20%3D%2010%2A%2810%29%20-%208%5C%5Ca_%7B10%7D%20%3D%20100%20-%208%5C%5Ca_%7B10%7D%20%3D%2092)
The answer is 6 pi because you have to divide 18 by 3. That gives you 6.

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 ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
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: ![20\div2=10](https://tex.z-dn.net/?f=20%5Cdiv2%3D10)
Second circle's radius: ![10\div2=5](https://tex.z-dn.net/?f=10%5Cdiv2%3D5)
Third circle's radius: ![5\div2=2.5](https://tex.z-dn.net/?f=5%5Cdiv2%3D2.5)
Now let's find the area of each circle.
<em>First Circle</em>: ![\pi \cdot10^2 = \pi\cdot100=3.14\cdot100=314](https://tex.z-dn.net/?f=%5Cpi%20%5Ccdot10%5E2%20%3D%20%5Cpi%5Ccdot100%3D3.14%5Ccdot100%3D314)
<em>Second Circle</em>: ![\pi\cdot5^2 = \pi \cdot25 = 3.14\cdot25=78.5](https://tex.z-dn.net/?f=%5Cpi%5Ccdot5%5E2%20%3D%20%5Cpi%20%5Ccdot25%20%3D%203.14%5Ccdot25%3D78.5)
<em>Third Circle:</em> ![\pi \cdot 2.5^2 = \pi \cdot6.25 = 3.14\cdot6.25=19.625](https://tex.z-dn.net/?f=%5Cpi%20%5Ccdot%202.5%5E2%20%3D%20%5Cpi%20%5Ccdot6.25%20%3D%203.14%5Ccdot6.25%3D19.625)
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 ![81.7575\cdot1.49\approx121.82](https://tex.z-dn.net/?f=81.7575%5Ccdot1.49%5Capprox121.82)
Hope this helped!!
