First you take 29 over 185 and x over 100 and you cross multiply which gives you 185x is equal to 2900 then you take 185x and 2900 and you divide both by 185 and you end up with x equals 15.68 or 15.68% which is letter B
Answer: d=5
Step-by-step explanation:
Arithmetic progression
An=a1+d(n-1)
An= nth term
A1= first term
D= common difference
N= nth position
We are given the 4th and 7th terms
For 4th term,n=4
A4=a1+d(4-1)
A4= 16
16= a1+d(4-1)
16= a1+3d........equation 1
For the 7th term,n=7
A7=a1+d(7-1)
A7= 31
31=a1+6d......equation 2
Bring them together
16=a1+3d
31=a1+6d
Subtract equation 1 from 2
So we have
15=3d
D=15/3
D=5
Therefore, the common difference is 5
Answer:
5.9× 10^4
Step-by-step explanation:
I'm assuming that by "104" you actually meant "10^4," which reads "fourth power of 10." Please be sure to use the symbol " ^ " to express exponentiation.
The sum of 2.5 × 10^4 and 3.4 × 10^4 is (2.5 + 3.4)×10^4
or
5.9× 10^4
<span>I think the answer would be:
B) y= 4 cos 2 theta</span>
Answer:
I'm assuming you meant arithmetic progression. If the common difference is d and because 18 - 8 = 10 we can write 17 + 10d = 13. Solving for d we get d = -0.4 or -2/5.
