Answer:
The weight of the wood before he chopped it is 245 N
Step-by-step explanation:
The law of conservation of mass states that for a given isolated system, mass (or matter) can not be created neither can it be destroyed, but it can be transformed into different forms
Therefore, whereby all the wood Chuck chops is taken as firewood, (wood which is dry is about 100% consumable as firewood) the mass of the wool before he chopped the wood = The mass of the firewood he had after chopping the wood = 25 kg
Weight = Mass × The acceleration due to gravity, g
g = Constant = 9.8 m/s²
The weight of the wood before he chopped it = 25 kg × 98 m/s² = 245 N.
Answer:
P(-4,-8)
Step-by-step explanation:
Given two lines:
![y = 4x + 8;$ and $ \\y = -0.25x - 9](https://tex.z-dn.net/?f=y%20%3D%204x%20%2B%208%3B%24%20and%20%24%20%5C%5Cy%20%3D%20-0.25x%20-%209)
To determine the point of intersection P of the lines, we equate the two lines and solve for (x,y).
![4x + 8= -0.25x - 9\\4x+0.25x=-9-8\\4.25x=-17\\$Divide both sides by 4.25$\\x=-4\\$Recall:$\\y = 4x + 8\\=4(-4)+8\\=-16+8\\=-8](https://tex.z-dn.net/?f=4x%20%2B%208%3D%20-0.25x%20-%209%5C%5C4x%2B0.25x%3D-9-8%5C%5C4.25x%3D-17%5C%5C%24Divide%20both%20sides%20by%204.25%24%5C%5Cx%3D-4%5C%5C%24Recall%3A%24%5C%5Cy%20%3D%204x%20%2B%208%5C%5C%3D4%28-4%29%2B8%5C%5C%3D-16%2B8%5C%5C%3D-8)
Therefore, the intersection point P of the lines is: P(-4,-8)
Answer:
1/10
Step-by-step explanation:
P( 1st out of ink) = out of ink/total
=2/5
Then we have 4 pens left, 1 out of ink
P( 2nd pen out of ink) = out of ink/total
=1/4
P(2 pens out of ink) =P( 1st out of ink) * P( 2nd pen out of ink)
= 2/5* 1/4
=1/10
