Answer:
how long is the shelf
Step-by-step explanation:
Answer:
(1, -2)
Step-by-step explanation:
Subtracting the first equation from the second gives ...
(5x +y) -(3x +y) = (3) -(1)
2x = 2 . . . . . collect terms
x = 1 . . . . . . . divide by 2
Then substituting into the first equation, we have ...
3·1 +y = 1
y = -2 . . . . . . subtract 3
The solution is (x, y) = (1, -2).
Answer:
Part a) The area of the actual fish pond is 
Part b) The length of the fence will be 
Step-by-step explanation:
we know that
The scale drawing is

step 1
Find the actual dimensions of the fish pond
To find the actual dimensions divide the measure of the drawing by the scale drawing
step 2
Find the area of the actual fish pond
The area of the fish pond is equal to the area of a circle p[lus the area of rectangle

we have



substitute

step 3
Find the length of the fence around the entire fish pond
The perimeter of the fish pond is equal to the circumference of a complete circle plus the length of 75 ft two times
so

we have

substitute
