Answer:
The correct answer is t < 60.
Step-by-step explanation:
Lauren wants to keep her cell phone bill below $60 per month.
Lauren's current cellphone plan charges her a fixed price of $30 and per text price for one text is $0.50.
Let Lauren sends t texts in a complete month.
Total money spent on texts in a month is given by $ (0.50 × t)
Therefore Lauren's total spent in a month is given by $ (30 + (0.50 × t)).
But this amount should be under $60 as per as the given problem.
∴ 30 + (0.50 × t) < 60
⇒ (0.50 × t) < 30
⇒ t <
⇒ t < 60.
So in order to keep her phone monthly bill under $60, Lauren should keep her number of texts below 60.
Answer:
The standard form of is 0.0000002
Step-by-step explanation:
Answer:
+
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as
// use the to transform the expression
Convert to
=
(here a = 2, n = 5, m = 2)
Then convert to
=
(here a = 3, n = 10, m = 1)
Now we get =
+
. This is the simplified form, which is the answer.
