Answer:
Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
Step-by-step explanation:
<span>The equations that show a direct variation between x and y when solved for y are:
</span><span>A. -10+y=3x-10
B. y=-1/8x
</span>
Since k is constant (the same for every point), we can find k when given any point by dividing the y<span>-coordinate by the </span>x<span>-coordinate. For example, if </span>y varies<span> directly as </span>x , and y<span> = 6 when </span>x<span> = 2 , the constant of </span>variation<span> is k = = 3 . Thus, the equation describing this </span>direct variation<span> is </span>y<span> = 3x .</span>
Recognize that "( ) over 2^3" means ( ) • 2^-3. Use the rule of exponents
.. (a^b)^c = a^(b•c)
= 2^-16•5^10•19^-2 • 5^-8*2^-12 • 2^28
Now, you can use the rule of exponents
.. (a^b)*(a^c) = a^(b+c)
= 2^(-16 -12 +28) • 5^(10 -8) • 19^-2
= 5^2 • 19^-2
= 5^2 / 19^2
= 25/361
Answer:
because the square root of 10 is an irrational number, and only rational numbers are integers. integers are whole numbers and have no fractions or decimels... hope it helps
2/4 is equal to 3/6 because they both are equal to 1/2
