Answer:
$4.75 for 1 pint of pint. The unit rate is the amount per pint.
Step-by-step explanation:
Part A is irrational, but Parts B and C are both rational.
We know that Part A is irrational because an irrational number added to a rational number is still irrational. Also, an irrational number multiplied by a rational number is still irrational.
With Part B, we have an irrational number in the square root of 7. However, it is then squared to give us 7. This leaves us with 7 times a^2 which is rational. Two rational numbers multiplied still give us a rational number.
Finally, Part C only involves adding and multiplying rational numbers. Since that can only yield rational numbers, it must be rational.

Answer:
672
Step-by-step explanation:
Okay so, the surface area of a figure is just all the areas of the faces added together. The front face ( 9x16 ) would be 144. The back face would be 12x9 or 109. The base would be 20x9 or 180. Now, this is where it might get tricky. The triangles will be 12x20x0.5 or 1/2. The answer for that would be 120. Now since there are two, multiply the 120 by two. ( Technically, since there are two of the same triangles you would not need to multiply by 0.5, but just to be safe i'll do it here. ) Finally, add all the areas together. The final answer is 672. Hope this helps!
Answer:
-6m-54, and y-x
Step-by-step explanation:
1: if m is less than 9, and 9•6 is 54, then 6m -54 will be less than 54
that means it will be negative. so you take |6m-54| out of absolute value, and make it negative: -6m-54
2: for this one, y is greater than x, so the overall answer must be positive. remove the absolute value sign, but don't change the equation.
|y-x|=y-x
