Answer:
B. 47
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =3 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
5-3 =2
d=2
n = the term number we are looking for
an = 3 + 2(n-1)
We are looking for the 23rd term so n=23
a23 = 3 +2(23-1)
= 3 +2(22)
= 3+44
= 47
You would take the amount of increase and divide it by the amount of total cost over the time period of certain months. Then you would multiply that number by the percentage of increase gained, and subtract 96.12 to get your answer.
Answer:
y = 95° and x = 21°
Step-by-step explanation:
y + 85° = 180° { being co-interior angles }
y = 180° - 85°
y = 95°
y = 4x + 11°[ being vertically opposite angles ]
95° = 4x + 11°
4x = 95° - 11°
4x = 84°
x = 84° / 4
x = 21°
