Answer: 8
Step-by-step explanation:
distributive property = -18 + 3r = 6
cross river = 3r = 6 + 18
add = 3x = 24
lastly, divide = 8
For a good cut of the edge ,The wood chisel ,who is cutting edge, the angle must be always less than 90°.
→ When angle between Axe and the point of contact on the edge is less than 90 degrees it will take less time to cut the edge.
→ When angle is small, the pressure on Wood chisel's body will be more , which will make him tired and take longer time to cut the edge at the point from where he or she wants to cut the edge.
So, for a perfect cut angle should be between the limits:
45< Angle < 90.
From my point of Correct option should be (D) 60°.
I think The best way to test this hypothesis would be to measure the total energy of the aquarium before feeding and the energy of the food fed to the fish. Then measure the energy in the aquarium after feeding and determine the difference.
Question 3:
If the diver is being pulled up at 25 feet every minute, in 10 minutes they would have been pulled up 10 times that
10*25=250
The diver is now 200 feet below, but 10 minutes ago they would have been 250 feet deeper so:
200+250=450
450 feet
40(12.62) + 7(12.62(1.5)) = 504.80 + 7(18.93) = 504.80 + 132.51 =
637.31 <===
