Answer:

The perimeter of one of the trapezoids is equal to (16+8\sqrt{2})\ in

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of a square is

P=4b

where

b is the length side of the square

step 1

Find the length side of the smaller square

16=4b

b=16/4=4\ in

step 2

Find the length side of the large square

48=4b

b=48/4=12\ in

step 3

Find the height of one trapezoid

The height is equal to

h=(12-4)/2=4\ in

step 4

Remember that in this problem, one trapezoid is equal to one square plus two isosceles right triangles.

Find the hypotenuse of one isosceles right triangle

Applying Pythagoras Theorem

c^{2}=4^{2} +4^{2} \\ \\c=4\sqrt{2}\ in

step 5

Find the perimeter of one of the trapezoid

The perimeter is equal to

P=(4\sqrt{2} +4+4\sqrt{2}+12)\\ \\P=(16+8\sqrt{2})\ in

Solve 3x^2=-12-6x by completing the square​
Lelu [443]

Answer:

x = - 1 ± i \sqrt{3}

Step-by-step explanation:

Given

3x² = - 12 - 6x ( add 6x to both sides )

3x² + 6x = - 12 ( divide through by 3 )

x² + 2x = - 4

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = - 4 + 1

(x + 1)² = - 3 ( take the square root of both sides )

x + 1 = ± \sqrt{-3} = ± i \sqrt{3} ( subtract 1 from both sides )

x = - 1 ± i \sqrt{3}

each time kim pour water from a jug into a glass, exactly 10% of the water remaining in the jug is used. What is the minimum num
Gnoma [55]

The <em><u>correct answer</u></em> is:

At least 7 times.

Explanation:

Since 10% of the water in the jug is removed each time, this means that 100-10=90% of the water remains.

After two times, we would have 0.9(0.9) = 0.81 = 81% of the water; each time she pours, the number of times 0.9 is multiplied by itself changes.  This makes this an exponential inequality (it is not an equation, as we want "less than half of the water"):

0.5 < 0.9^x

To solve this, we will use logarithms:

\log_{0.9}(0.5)
