Step-by-step explanation:
1. x² = V12²+16²
= V144+256
= V400
x² = 20
2. x² = V14²-11²
= V196-121
= V75
x = V25×3
= 5V3
3. x² = V9²-7²
= V81-49
= V32
x = V16×2
= 4V2
Answer: C. 50 2/3
Step-by-step explanation: Multiply 9 1/2 and 5 1/3.
Answer:
D. He should add between 2 cups and 3 cups of dirt.
Step-by-step explanation:
First we need to take the ratio of dirt to peat moss.
8 parts dirt : 3 parts peat moss.
Now we take the ratio and find the value of dirt.
8 : 3 = 
x : 1 = 

We now multiply both sides by 1.



So now we substitute x.
2.67 Cups Dirt : 1 Cup Peat Moss
