Natral whole rational irrational
Algebra is a very important branch of math.
Algebra is a lot like arithmetic which means it follows all the rules of arithmetic, and it still uses the four main operations that arithmetic is built on.
In arithmetic, the only thing that was unknown was the answer to the problem. For example, 39 + 2 = 41. In algebra, we use a variable to represent the number. A variable is a letter that represents any number. The most common variable is "x".
Answer:
- arc second of longitude: 75.322 ft
- arc second of latitude: 101.355 ft
Explanation:
The circumference of the earth at the given radius is ...
2π(20,906,000 ft) ≈ 131,356,272 ft
If that circumference represents 360°, as it does for latitude, then we can find the length of an arc-second by dividing by the number of arc-seconds in 360°. That number is ...
(360°/circle)×(60 min/°)×(60 sec/min) = 1,296,000 sec/circle
Then one arc-second is
(131,356,272 ft/circle)/(1,296,000 sec/circle) = 101.355 ft/arc-second
__
Each degree of latitude has the same spacing as every other degree of latitude everywhere. So, this distance is the length of one arc-second of latitude: 101.355 ft.
_____
<em>Comment on these distance measures</em>
We consider the Earth to have a spherical shape for this problem. It is worth noting that the measure of one degree of latitude is almost exactly 1 nautical mile--an easy relationship to remember.
((6)^3 (g^5)^3 (h)^3 + (-4)^3)
(216 x g^15 x h^3 - 64
216g^15h^3 - 64
Answer:
1) 
.
2) 
hence, answer is 7/12.
3) We have to divide £72 in the ratio 2:3:1
the total of the ratio is=2+3+1=6
so on dividing 72 into 6 parts we have 72/6=12
First '2' parts=2×12=24
second '3' part=3×12=36
last '1' part=1×12=12
so dividing £72 in the ratio 2:3:1 is: £24,£36 and £12
4) 39 people out of 65 have blonde hair.
Number of people who do not have blonde hair=65-39=26
percentage people who do not have blonde hair is given by:
Hence, percentage people who do not have blonde hair is 40%
5) 20% of 90= (20/100)×90
=18
Hence, 20% of 90 is 18.
6) Factorise
7) Expand
8)
.
9)
10)
11) x= -4 y=3
and z=4 x-y^3
z=4×(-4)-3^3
z= -43
12) 
13) 
Hence x= -2
14) 5,10,15,20,....
Hence, nth term is 5n.
15) (63×128)/32.9=245.106.
16) 938×21=19698.
