Area covered by the forest in the beginning = 1500km²
Decrease in area each year = 5.8% = 5.8/100 × 1500 = 87km²
Decrease in the area of the forest in <em>t</em> years = 87t
Area of forest now = y
y = 1500 - 87t
The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13
The two lines can be anything as long as they give this solution
For example, if you wrote x + y = 16 (you know their values already)
Then write another y - x = 10
From here you have your equations, turn them into the f(x) form.
x + y = 16 can be turned into y = 16 - x which is f(x)=16-x
y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x
Answer:
8 hours
Step-by-step explanation:
rental fee = 12 + 4/hr
spent = 44
44 = 12+4(hr)
32 = 4(hr)
32/4 = hr
hr = 8
Answer:
x=28
Step-by-step explanation:
4(x-5)=92
4x-20=92
add 20 to both sides
4x=112
divide 4 on both sides
x=28
Answer:
<h2>The answer is 56 m</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
To find the area we must first find the length of the rectangle using it's area.
That's
Area = length × height
From the question
Area = 96 m²
height = 4 m
So we have
96 = 4l
Divide both sides by 4
length = 24 m
Now we have
Perimeter = 2(24) + 2(4)
= 48 + 8
We have the final answer as
<h3>56m</h3>
Hope this helps you
