If the third term of the aritmetic sequence is 126 and sixty fourth term is 3725 then the first term is 8.
Given the third term of the aritmetic sequence is 126 and sixty fourth term is 3725.
We are required to find the first term of the arithmetic sequence.
Arithmetic sequence is a series in which all the terms have equal difference.
Nth term of an AP=a+(n-1)d
=a+(3-1)d
126=a+2d--------1
=a+(64-1)d
3725=a+63d------2
Subtract second equation from first equation.
a+2d-a-63d=126-3725
-61d=-3599
d=59
Put the value of d in 1 to get the value of a.
a+2d=126
a+2*59=126
a+118=126
a=126-118
a=8
=a+(1-1)d
=8+0*59
=8
Hence if the third term of the arithmetic sequence is 126 and sixty fourth term is 3725 then the first term is 8.

15 5/8 divided by 5
First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8
125/8 divided by 5/1 (which is equal to 5)
Next, we do Keep Change Flip.
Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.
1 * 125 = 125
8 * 5 = 40
Then, we get 125/40 = 3 5/40 BUT WAIT
We can reduce it once more! Divide 40 by 5

Answer:
14/18 = 0.778
Step-by-step explanation:
14 divided by 2 = 7
18 divided by 2 = 9
7/9 is the same as 7 divided by 9
= 0.778
Answer:
D
Step-by-step explanation:
you multiply by 180/pi
usually in my calculator i would always type 8(1/180) so i dont know why its saying this but u said u were gonna cry so i looked it up and it came up w this.
"To convert from radians to degrees, multiply the radians by 180°π radians ."
