Answer:
The answer to your question is: # of times = 60.7
Step-by-step explanation:
data
7.4 billion people
each person occupied 13 inches
Earth circumference = 25000 miles
length of the lines = 13 in x 7.4 billion people
= 13 x 7 400 000 000
= 9.62 x 10 ¹⁰ in
Convert in to miles
1 mile --------------- 63360 in
x mi --------------- 9.62 x 10 ¹⁰ in
x = 1518308.1 mi
Now divide, the line of people by the circumference
# of times = 1518308.1 mi / 25000 mi = 60.7
7:45-5:51 gives you the difference in times remember 60sec per min (1:54)
turn it into only seconds so 60+54=114s and 7x60+45=645s
114/645 gives you the percentage of difference
You need to put the parentheses around (1+2)
Your Answer should look like
(1+2)x3=9
These are the elements of the matrix
Elements of the first row are h11 h12 h13, of the second row h21 h22 h23.
Than we can conclude that element h23 worth 75.
Good luck!!!
Answer:
((x * 7) - 4) = 8 + x
Step-by-step explanation:
X - is a number
if you need to solve it:
x * 3 = 8 +x
3x = 8 + x
2x = 8
~~(x=4)~~
Hope this helped
