Answer:

The perimeter of the rectangle is represented by p = 32\cdot d + 9, measured in centimeters.

Step-by-step explanation:

The perimeter (p) of a rectangle, measured in centimeters, is represented by this formula:

p = 2\cdot (w+l)

Where w and l are width and length, measured in centimeters.

If w = 6.8\cdot d-4.2 and l = 9.2\cdot d+8.7, the expression that represents the perimeter is:

p = 2\cdot (16\cdot d +4.5)

p = 32\cdot d + 9

The perimeter of the rectangle is represented by p = 32\cdot d + 9, measured in centimeters.

Find the value of y to the nearest tenth.
Jobisdone [24]

Step-by-step explanation:

the easiest approach seems to be the law of sines :

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and the angles are always opposite of each other.

we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.

10/sin(90) = 10/1 = 10 = y/sin(37)

y = 10×sin(37) = 6.018150232 ≈ 6.0

a man made lake is stocked with 10,000 fish. This population is expected to decline by an annual rate of 15%. Predict the fish p
Rasek [7]
I got 2,500 left after 5 years.
10,000*15% = 1,500 or you could do 10,000*.15 = 1,500

That is a loss of 1,500 fish per year.
If you want to think of this as a proportion then you would do
Year/fish lost

1/1,500 = 5/x
X=5*1,500
X=7,500

The population of the fish after 5 years equals
10,000-7,500 = 2,500
So your answer is 2,500 fish are left
