Answer:
219,000
Step-by-step explanation:
How many 6 hour periods are in a day?
24 divided by 6 is 4.
150 times 4 equals 600
finally 600 times 365 equals 219,000 planes a year
Answer:
The third number is 180.
Step-by-step explanation:
Let the third number be 9x where x is an integer.
48 = 2*2*2*2*3
264 = 2*2*2*3*11
9x = 3*3*x
2*2*2*2*3*3*11*x = 7920y where y is an integer
1584x = 7920y
so x = 7920y / 1584= 5y.
Now the GCD is 12 so x must have 4 as one of its factors.
Also x is a multiple of 5 so it could be 20 then y would be 4.
If x = 20 then the third number is 9*20 = 180.
This checks out OK.
Complimentary angles, when added, will equal 90 degrees
so < DFG and < JKL, when added = 90
x + 5 + x - 1 = 90
2x + 4 = 90
2x = 90 - 4
2x = 86
x = 86/2
x = 43
< DFG = x + 5......43 + 5 = 48 degrees <==
< JKL = x - 1........43 - 1 = 42 degrees <==
Answer:the library checks out 2 times more fiction books than the nonfiction books.
Step-by-step explanation:
Total number of fiction books that the Library checks out in an hour is 4.
Total number of non fiction books that the Library checks out in an hour is 2.
To determine how many times more fiction books that they check out than the nonfiction books, we would divide the total number of fiction books that the Library checks out in an hour by the total number of non fiction books that the Library checks out in an hour. It becomes
4/2 = 2
Answer:
5x + 9
Step-by-step explanation:
f(x) = 3x+4
g(x) = 2x + 5
(f+g)(x)
(3x+4) + (2x + 5)
= 5x + 9
