Answer:
3.6 for tomatoes and 8.4 for lettuce
Step-by-step explanation:
70% of 12=8.4
30% of 12=3.6
check: 3.6+8.4=12
Your formula for this is
and
. Get everything on one side of the equals sign, set it equal to 0 and factor. When you do this you get (x-3)(x+27). The Zero Product Property rule tells us that either x-3 = 0 or x+27 = 0 and that x = 3 and -27. The only thing in math that will NEVER be negative besides time is distance/length, therefore, x cannot be 27 and has to be 3.
Answer: 39 25/50
Step-by-step explanation:
0.78 ( 78% ) = 39/50
0.79 ( 79% ) = 39/50 + 1/2
25 is half of 50
39 25/50
Answer:
400m of fencing is required to surround the area.
Step-by-step explanation:
First we need to find one side of the square. We know the area of a square is:
A = x²
We can use this information to find the length of a side of the square.
10000m² = x²
x = √10000m²
x = 100m
Now that we know what the length of the square yard is, we can calculate the perimeter. The perimeter of a square is:
P = 4x
For our problem:
P = 4(100m)
P = 400m
400m of fencing is required to surround the area.
