When Javier and his father went to dinner, the bill was $34. If they tipped the waiter 20%, how much did they spend in total?

Kamila [148]

Answer:

Not sure if this is right, but I got $40.8.

Step-by-step explanation:

I first turned 20% into a decimal. (0.20).

Then I multiplied 0.20 and 34 which is 6.8.

I then added 34 since it’s the original cost to 6.8 since that’s the tip amount.

After that, you should get $40.8.

Classify the sequence arithmetic , geometric, or neither

Feliz [49]

Answer:

Geometric

Step-by-step explanation:

Given terms are {3, -1, 1/3, -1/9............}

If we have common difference between the terms then it is arithmetic

If we have common ratio between the terms then it is Geometric

Difference of 3 and -1 is 4

Difference of 1/3 and -1 is -4/3

Common difference it not same so it is not Arithmetic

Now we check common ratio

we divide second term by first term

first term is 3 and second term is -1

$\frac{-1}{3}$

now we check with next two terms

$\frac{\frac{1}{3}}{-1}=\frac{-1}{3}$

common ratio is -1/3

So this is Geometric
