39.99*.3=
$12 off of the original price
17.99*.06=
$1.08 is the sales tax
17.99+1.08= the total price
$19.07 is the final answer
19 dollars and seven cents is what he paid for the headphones.
The tax was 1 dollar and eight cents.
Use Pythagoras’ theorem:
a^2+b^2=c^2
But we rearrange this formula to make it
c^2-a^2=b^2
So 25^2-15^2=b^2
625-225= b^2 = 400
You now need to find the square root of 400 to find the square root of b
sqrt of 400 is 20
So 20 is the missing length in this triangle

A: How many text messages would you have to send or receive in order for the plans to cost the same each month?
Answer: 100
Step-by-step:
$.20x100=$20
$40+$20=$60
b: If you send or receive an average of 50 texts each month, which plan would you choose?Why?
Answer: A
Because $.20x50=$10
$40+$10=$50
200 meters per minute.
A minute is 60 seconds. 60 divided by 3 is 20. 20 Times 10 is 200.
