Answer:
398-cent stamp for postage.
Step-by-step explanation:
For one letter, Travis needs 37-cent stamp
For four letters, Travis needs 37-cent stamp x 4 letters
= 148-cent
Again,
For one postcard, he needs 25-cent stamp
For ten postcards, he needs 25-cent stamp x 10 postcards
= 250-cent
Therefore, he will spend = (148-cent + 250-cent) = 398-cent stamp for postage.
√72 can be written as 3√8 , √128 as 4√8.. Here, we have to solve √72 -√8 +√128 .. i.e, 3√8 - √8 + 4√8.. which is equal to 6√8 or can be written as 12√2 //
Answer:
x = 3
Step-by-step explanation:
In a 30-60-90 triangle the side between 60 and 90 degree angle is a, the side between 30 and 90 degree angle is a√3, and the hypotenuse is 2*a.
Given that the side that is supposed to be a is currently √3, we know that the missing side x must be:
a√3 (We know that a, in this case, is √3, so substitute)
x = (√3) * (√3)
x = 3
I am almost positive that the answer is the first one.
