Anna has 196 pepper plants that she wants to plant in a square formation how many pepper plants should she plant in each row
skad [1K]

She should plant 14 plants in each row

Step-by-step explanation:

Given

Total pepper plants = 196

As the plants have to be in square shape, the number of rows and the plants in each row will be equal

Let x be the number of rows

Then

x^2 = 196\\

Taking square root on both sides

\sqrt{x^2} = \sqrt{196}\\x = 14

Hence,

She should plant 14 plants in each row

I need help with this question

Since the angle is positive, you can find any coterminal angle by applying:


Angle + x = 2π ==> 7π/6 + x = 2π ==> x = 2π - 7π/6

x= 12π/6 -7π/6 = 5π/6

So the angle 5π/6 is the coterminal of 7π/6
