The correct question is
<span>how many times as large is the approximate radius of a mercury atom, 1.50*10^-11 meter, as the approximate radius of a hydrogen atom, 2.5*10^-11
</span>
Since both are conveniently --------> *10^-11
<span>we can just divide 2.5 by 1.5
</span>2.5/1.5-------> 1.6666
<span>So a hydrogen atom is 1.67 times larger than a mercury atom</span>
Answer:
a
Step-by-step explanation:
this is a partA because t
Time taken by Julian to complete 24 km trip to Guelph at 12 km/h =
hours
Time taken by Julian for return trip at 8 km/h = 
hours
As given, the total distance is 24 + 24 = 48 km.
And the total time is 2 + 3 = 5 hrs.
Hence, the average speed for the entire trip is = 
The answer is 9.6 km/hour.
Answer:
63 sandwiches
Step-by-step explanation:
Pete and his friend Danny volunteered to bring sandwiches for lunch at a homeless shelter
They brought 7 loaves of bread
Each loaves have 18 slices
They used 2 slices each to make the sandwich
The first step is to calculate the total number of slices
Sinces 7 loaves of bread are used and each of them contain 18 slices then, the total number of slices can be calculated as follows
= 7 ×18
= 126 slices
Therefore since 2 slices of bread is used to make one sandwich then, the number of sandwiches that was made can be calculated as follows
= 126/2
= 63
Hence 63 sandwiches were made for the shelter
Answer:
Step-by-step explanation:
The domain of the function y=tan(x) ) is all real numbers except the values where cos(x) is equal to 0 , that is, the values π2+πn for all integers n . The range of the tangent function is all real numbers.
