Answer:
-0.4x - 0.30 or
Step-by-step explanation:
Change all the fractions to decimals.
-2/5 = -0.4 Distribute that over x and 0.8 1/50 = 0.02
you get -0.4x -0.32 + 0.02
Change all the decimals to fractions.
0.8 is 8/10 so -2/5 times 8/10 is -16/50
-2x/5 - 16/50 + 1/50 add or subtract the fractions to get -15/50 Then reduce (÷5)
-2x/5 - 3/10
Answer:
Approximate length of the diagonal fencing needed is 45.25 cm.
Step-by-step explanation:
Here, each side of the square shaped land = 32 ft
Now, the diagonal fencing is made in side the plot so that the land is divided into two right triangles.
<u>In the triangle:</u>
Base side of the triangle = 32 cm
Perpendicular length of the triangle = 32 cm
Let us assume the hypotenuse of the triangle = k cm
⇒The length of the diagonal in the square = k cm
by <u>PYTHAGORAS THEOREM</u> in a right angled triangle:
⇒
or, k = 45.25 cm
Hence,the approximate length of the diagonal fencing needed to fence the square land is 45.25 cm.
