Answer:

I think the answer should be 54 pi centimeters but I can't see all the options, area of a circle is pi r^2 so if the diameter is 18, diameter = 2r so the radius is 9. pi 9^2 is 81 pi, then the same for the 3 unshaded ones and just subtract the area of the 3 white circles (27 pi) out of 81 pi.

A farmer is going to divide her 30 acre farm between two crops. Seed for crop A costs $5 per acre. Seed for crop B costs $10 per
jenyasd209 [6]

Answer:

30 acres of A

0 acres of B

Step-by-step explanation:

On forming the equations we get

Acres = A+B \leq 30  .............(1)

Seed = 5A + 10B \leq 200 ...........(2)

Profit = 160A+50B

Upon rearranging this we get

A= 30-B     sing equation (1)

A=40-2B   using equation (2)

 On plotting these inequalities on the cartesian planes we will get the following points of intersection (0,20) (20,30) (30,0)

Now using these coordinates (A,B) to get Maximum profit

P= $1000 for (0,20)

P=$4700 for (20,30)

P= $4800 for (30,0)

clearly for (30,0) we will get the maximum profit on the crops

Type a digit that makes this statement true.<br><br> 768,72<br> is divisible by 6.<br><br> Help Me
kiruha [24]

Answer:

6

Step-by-step explanation:

Rule for divisibilty of 6:

  • sum of place values is a multiple of 3
  • an even number

Step 1: dd the integers

  • 7 + 6 + 8 + 7 + 2 + x
  • 30 + x

Now, we have a couple options:

  • x = 3
  • x = 6
  • x = 9

You can use any of these three values,

But the number has to be even, so the last digit has to be even. The correct answer is 6.
