A is the answer because if it is 2.50 each day then the answer is 2.50d
Answer:
200 and 546
Step-by-step explanation:
dejar a = Primer periodo (first term)
dejar d = Diferencia común (common difference)
dejar 100th término = T100
dejar 273 término = T 273
utilizando
Tn = a + (n - 1)d
T100 = 2 + (100 - 1) 2
= 2 + 99 ×2
= 2 + 198
= 200
T273 = 2 + (273 - 1) 2
= 2 + 272 × 2
= 2 + 544
= 546
In 36 days will the science and math teachers both give tests on the same day again.
<u>Step-by-step explanation:</u>
Here we have , The 6th grade science teacher gives a test every 12 days and the math teacher gives a test every 9 days. Today, both the science and math are giving tests. We need to find In how many days will the science and math teachers both give tests on the same day again . Let's find out:
It's given that science teacher gives a test every 12 days and the math teacher gives a test every 9 days . In order to find the number of days after which they'll give test at same day , we will find LCM of 12 & 9 . i.e.
⇒
and ,
⇒ 
Hence , LCM of 12 and 9 is 36 . Therefore , In 36 days will the science and math teachers both give tests on the same day again.
