The correct answer is "Linear Pair Theorem". The theorem states that if 2 angles make a linear pair, then they are supplementary (add up to 180).
Step-by-step explanation:
please sorry to barge into your question without any reasonable answer all I want to say is that this is a graph and I think that the domain and range this is increasing to calculate like the unit for example you have - 9 and - 3 you should calculate how many units are between -9 and -2 I'm not sure and I just really need marks now point where I can get on with my procedure so sorry for just barging in like that I'm so sorry
Answer:
4.5
Step-by-step explanation:
The equation of an area of a circle is A=πr² where r is the radius.
The radius is also half the diameter. So the radius of the quarter is 1.2
A=π(1.2)²
A=π(1.44)
A=4.52389
Answer:
48 bags
Step-by-step explanation:
step 1
Find the area of the path
we know that
The area of the path is equal to the area of the outer circle minus the area of the inner circle
![A=\pi [rb^{2}-ra^{2}]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Brb%5E%7B2%7D-ra%5E%7B2%7D%5D)
we have
----> the radius is half the diameter
----> the radius is half the diameter
substitute
![A=3.14 [19^{2}-16^{2}]](https://tex.z-dn.net/?f=A%3D3.14%20%5B19%5E%7B2%7D-16%5E%7B2%7D%5D)
step 2
Find out the number of sand bags needed
we know that
One bag of sand can cover 7 yd^2
so
Divide the total area by 7 to determine the number of bags
Round up
Take both sides as powers of 4:
Do it again:
