Answer:
Step-by-step explanation:
Leaving aside that we don't know how much the carton weighs, the answer is 42 * 3.6 ounces (those are very big erasers).
W(carton) = 42*3.6 = 151.2
Answer:
y = -0.25x + 2.25
Step-by-step explanation:
First, you can simplify the equation of the line it's perpendicular to (2y = 8x - 6) by dividing both sides by 2. This means you would get y = 4x - 3. From that you can conclude that the slope of that line is 4.
Lines always have a slope that is the negative reciprocal of the slope of the line they are perpendicular to, so you know the slope of the line is going to be -1/4.
So far, you have the equation y = -1/4x + b and you have to find b.
You can substitute in the point (-3, 3) so you would have 3= -1/4 * -3 + b
Solving,
3 = 3/4 + b
b = 2 and 1/4
Therefore the equation is y = -1/4x + 2 1/4 or y = -0.25x + 2.25
Answer:

Step-by-step explanation:
<h2>
Hello!</h2>
The answer is:
C. ![0.25\frac{g}{cm^{3} }](https://tex.z-dn.net/?f=0.25%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D)
<h2>
Why?</h2>
The density is the relation between the mass and the volume of an object. We are given four options to chose, and we can find the correct one by doing the following calculations:
![Density=\frac{mass}{volume}=\frac{5g}{20cm^{3}}=0.25\frac{g}{cm^{3}}](https://tex.z-dn.net/?f=Density%3D%5Cfrac%7Bmass%7D%7Bvolume%7D%3D%5Cfrac%7B5g%7D%7B20cm%5E%7B3%7D%7D%3D0.25%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%7D)
So, the correct options is C. ![0.25\frac{g}{cm^{3} }](https://tex.z-dn.net/?f=0.25%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D)
Have a nice day!
