First, let’s divide 365 by 7 to find out how many weeks are in a year. (52) Then we can divide that number by 40768 and we get answer choice 784.
Answer:
20 square units
Step-by-step explanation:
B * H
height = 5
base = 4
4 * 5
20
42 (1- 25/100) = 63/2 = 31.5 dollars
answer is $31.50
hope it helps
Answer:
18.7939 m
Step-by-step explanation:
-Let x be the distance between John and clock tower.
-Let y be the vertical distance from the eyes of the two men standing to the top of the clock tower.
#Taking the right triangle ACD:
#Taking the right triangle ABD:
#We equate the two yo solve for x and y;
Hence, John's distance from the tower's base is 18.7939 m
If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.
With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).
The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.
If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.
