Answer:
How much soil for a raised bed?
Answer: The cost to fill a raised bed with bagged fertile soil (planting mix) adds up quickly. The volume of soil you need is 12 feet times 4 feet times 1.5 feet (length times width times depth equals volume), which comes to 72 cubic feet
Step-by-step explanation:
Given:
The inequality is:
![y](https://tex.z-dn.net/?f=y%3C%5Csqrt%7Bx%2B3%7D%2B1)
To find:
The domain and range of the given inequality.
Solution:
We have,
![y](https://tex.z-dn.net/?f=y%3C%5Csqrt%7Bx%2B3%7D%2B1)
The related equation is:
![y=\sqrt{x+3}+1](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx%2B3%7D%2B1)
This equation is defined if:
![x+3\geq 0](https://tex.z-dn.net/?f=x%2B3%5Cgeq%200)
![x\geq -3](https://tex.z-dn.net/?f=x%5Cgeq%20-3)
In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.
So, the domain of the given inequality is x>-3.
We know that,
![\sqrt{x+3}\geq 0](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B3%7D%5Cgeq%200)
![\sqrt{x+3}+1\geq 0+1](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B3%7D%2B1%5Cgeq%200%2B1)
![y\geq 1](https://tex.z-dn.net/?f=y%5Cgeq%201)
The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.
So, the domain of the given inequality is y>1.
Therefore, the correct option is A.
Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x
![\frac{x}{3x} \times 120 \\ =40](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3x%7D%20%20%5Ctimes%20120%20%5C%5C%20%3D40)
![\frac{2x}{3x} \times 120 \\= 80](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B3x%7D%20%20%5Ctimes%20120%20%5C%5C%3D%2080)
40 and 80 are in the ratio 1:2 of 120.
Hope it helps!!!
Pemdas, ok first 17 plus 8 is 15, 6 times 2 is 12 , so 15 minus 12 is 3. answer is 3
Answer:
see explanation
Step-by-step explanation:
(a)
AB = AO + OB = - a + b = b - a
(b)
OP = OA + AP = a +
(b - a ) = a +
b -
a =
