Answer:
w = 18; l = 62
Step-by-step explanation:
The formula for perimeter of a rectangle is P = 2l + 2w, where l represents length and w represents width
We know that the length can be found using the equation l = 3w + 8
Plugging this in for l in the original formula for perimeter gives us 160 = 2 * (3w + 8) + 2w
160 = 6w + 16 + 2w
160 = 8w + 16
144 = 8w
18 = w
Plugging 18 in for the second equation gives us 3 * 18 = 54 + 8 = 62 = l
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
Answer:
The sales tax is $19.80
The total cost is $349.80
Step-by-step explanation:
To find the sales tax, multiply 330 by 0.06 (6%)
To find the total cost add the sales tax, 19.80 with 330
For the axis of symmetry it will be -b/2a but in this case the axis of symmetry is going to be y=4. the x intercept will be the roots (2,0) and (6,0) and for the y intercept it will be (0,3) since the parabola crosses the y axis at (0,3)
