Answer:
180?
Step-by-step explanation:
Answer:
We need 5 bags of Vigoro Ultra Turf and 4 bags of Parkers Premium fertilizer.
Step-by-step explanation:
Let's first list the percentage compositions of each fertilizer type:
<u>Vigoro Ultra Turf:</u>
Nitrogen (N) = 29 kg
Phosphoric Acid (P2O5) = 3 kg
Potash (K2O) = 4 kg
<u>Parkers Premium</u>
Nitrogen (N) = 18 kg
Phosphoric Acid (P2O5) = 25 kg
Potash (K2O) = 6 kg
We can set up simultaneous equations to find out the amount of 100 kg bags of each fertilizer needed:
x = Vigoro Ultra turf (one bag)
y = Parkers Premium (one bag)
29x + 18y = 217 -Equation 1
3x + 25y = 115 -Equation 2
4x + 6y = 44 -Equation 3
Solving for x and y, we get:
x = 5
y = 4
This means we need 5 bags of Vigoro Ultra Turf and 4 bags of Parkers Premium fertilizer.
Answer: 1/50, or 0.02
Step-by-step explanation:
I'm assuming this is 5*10/25/100. if you just follow the equation, you get 50/25/100, which is 2/100, or 1/50.
Answer: g(-3) is 9 .
Step-by-step explanation:
So there are two functions and the first function says that to get the solution x has to be greater than 4 and -3 which is the input is not greater than 4 so you can't use that function to solve for g(-3).
using the second function , it says that x has to be less or equal to 4. And -3 is indeed less than 4 so you have to use the second function to solve for g(-3)
g(x) = -2x + 3 Input -3 and solve
g(-3) = -2(-3) + 3
g(-3) = 6 + 3
g(-3) = 9
