Answer: Option 'b' is correct.
Step-by-step explanation:
Since we have given that
Total number of birds = 14000
Let the number of birds on X be 'x'.
Let the number of birds on y be 14000-x
After one year, 20 percent of the birds on X have migrated to Y, and 15 percent of the birds on Y have migrated to X.
but The number of birds on each of the islands X and Y remains constant from year to year.
So, the equation would be
Hence, there are 6000 birds on island X.
Hence, Option 'b' is correct.
A negative sign in front of any expression, is in effect a factor of -1, so -7 for example is really the same as saying -1 * 7, because the -1 is multiplying it right in front of it, therefore
Answer:
42 square inches
Step-by-step explanation:
Area of a triangle = (1/2)(base)(height)
A = 1/2(12)(7)
A = 1/2(84)
A = 42
40% = 0.40
20 * 0.40 = 8
Solution: you answered 8 incorrectly
