Answer:

Canadian railcars show weight figures in both imperial and metric. Canadian railways also maintain exclusive use of imperial measurements to describe train length and height in feet and train masses in short tons. Canadians typically use a mix of metric and imperial measurements in their daily lives.

A book costs $25 .Marilyn bought the book during a sale with 15% discount. How much did she pay for the book

belka [17]

Original cost of the book = $25
Percentage of discount got by Marilyn while buying the book = 15%
Amount of discount got by Marilyn while buying the book = (15/100) * 25
= 375/100
= 3.75 dollars
So
The amount paid by Marilyn for buying the book = (25 - 3.75) dollars
= 21.25 dollars
<span>So the total amount paid by Marilyn for buying the book is $21.25. I hope the procedure for doing this problem is clear to you.</span>

The areas of the squares adjacent to two sides of a right triangle are 32units^2 and 32 units^2

adoni [48]

Answer:

x = 8 units.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

<em>The areas of the squares adjacent to two sides of a right triangle are 32 unit square and 32 units square. Find the length,x, of the third side of the triangle</em>

My answer:

Let a is the side length of the 1st square

The area of the 1st square is equal to 32 units square

<=> $a^{2} = 32$

<=> a = $4\sqrt{2}$ units

Let b is the length of the 2nd square

The area of the 2nd square is equal to 32 units square

<=> $b^{2}$ = 32

<=> b = $4\sqrt{2}$ units

Find the value of x

Applying the Pythagoras Theorem, we have:

$x^{2} = a^{2} + b^{2}$

<=> $x^{2} = 32 + 32$

<=> $x^{2} = 64$

<=> x = 8 units

Hope it will find you well.

How would you simplify this? Please help

$8^{\frac{4}{3}} = \sqrt[3]{8^4} = \sqrt[3]{(2^3)^4} = \sqrt[3]{2^{3*4}} = 2^4 = 16$

Answer: C (16).

$2\sqrt{6} - 6\sqrt{54} = 2\sqrt{6} - 2 * 3 * \sqrt{6} * \sqrt{9} = 2\sqrt{6}(1-3\sqrt{9}) = 2\sqrt{6}(1-3*3) = 2\sqrt{6}(1-9)=2*\sqrt{6}*(-8) = -16\sqrt{6}$
