First we need to find out the area of the square. Since 1/2 of the square( the triangle) is .32 square units, multiply .32 by 2 to find the area.

.32*2=64

Now, find the square root of .64

The square root of .64 is .8.

The side length of the original square is .8 units.

Hope this helps!

Answer:

0.8

Step-by-step explanation:

Let's say s is the side length of the square.  When the square is cut diagonally, each triangle has a base of s and a height of s.

Area of a triangle is:

A = ½ bh

Given A = 0.32, b = s, and h = s:

0.32 = ½ (s)(s)

0.64 = s²

s = 0.8

The side length of the square is 0.8 units.

Which property of operation could you use to show whether 7y + 7b + 3y and 7(y x b) + 3b are equivalent or not
Dmitry_Shevchenko [17]

Answer and explanation:

They are not equivalent because if we simplify the second expression, the result isn't the same:

7(y×b)+3b

= 7(yb)+3b

=7yb + 3b

Therefore 7yb+3b≠7y+7b+3y

And even though you meant

7(y+b)+3b

=7y+7b+3b

=7y+10b

7y+10b≠10y+7b

You have a 45-gallon jug and a 124-gallon jug. neither of the jugs has any markings (although you do know their capacities). des
Alja [10]
Pour 4  times of 124-gallon into a big jug.
Amount of water = 124 x 4 = 496 gallons

Then use the 45-gallon jug to scoop out the water 11 times.
Amount of water scooped out = 11 x 45 = 455 gallons

Water remaining = 496 - 450 = 1 gallon.
