The 70th term of an arithmatic sequence is 121.5 the common difference is 1.5. Find a12. (write a rule to find a12)WILL GIVE BRAINLIEST
Answers
Answer:
12th term = 34.5
Step-by-step explanation:
l = a + (n-1)*d
d = 1.5
70th term = 121.5
a + 69 * 1.5 = 121.5
a + 103.5 = 121.5
a = 121.5 - 103.5
a = 18
12 th term = 18 + 11 * 1.5 = 18 + 16.5 = 34.5
Answer:
= 34.5
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given = 121.5, then
a₁ + (69 × 1.5) = 121.5
a₁ + 103.5 = 121.5 ( subtract 103.5 from both sides )
a₁ = 18
Hence
= 18 + (11 × 1.5) = 18 + 16.5 = 34.5

Only A
Only B
Both A and B
Neither A nor B
Answers
Answer:
Both A and B
Step-by-step explanation:
A = {(3, −5), (4, 6), (−3, 9), (2, 7)}
-Each x goes to a different y so this is a function
B = {(2, 4), (−1, −7), (5, 6), (4, 3)}
-Each x goes to a different y so this is a function
Both!!
If you look at it, none of the x values are repeating with a differnt outcome, so you know that they both are correct.

The number of days the packet of food last is A = 50 days
What is unit conversion?
In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the number of days the packet of food last be A
And , from the unit conversion
1 kg = 1000 grams
The total amount of food in the packet = 1.5 kilograms
And , the amount Remi feeds her Guinea pig per day = 30 grams
So , number of days A = total amount of food in the packet / amount Remi feeds her Guinea pig per day
On simplifying , we get
A = 1500 / 30
A = 50 days
Hence , the number of days is 50
