At a music store, the price of a set of speakers is $245, plus the sales tax of 6.5%. What is the total cost of the speakers, including the sales tax?

Answers

In order to find out what the additional value of the sales tax would be,which is 6.5%, you have to find 1% of $245. Which is $2.45. As you're looking for 6.5%, you have to multiply $2.45 by 6.5, which gives you $15.93 (rounded). In order to find the cost including the sales tax, you have to add $15.93 to the original price of $245, which gives you $260.93.Therefore, the price of the speakers, including a sales tax of 6.5% is $260.93Hope this helps :)
So,

The total cost = cost + sales tax

cost + sales tax = x or total cost

1. cost = $245

2. sales tax = 0.065(cost)

245 + 0.065(cost) = x

Simplify
245 + 15.925 = x

Round to the nearest hundredth
245 + 15.93 = x

Collect Like Terms

260.93 = x

The total cost of the speakers, including tax, is $260.93.

What is the solution to the equation?12y + 6 = –18

A. y=-2
B. y=-1
C. y=1
D. y=2

Answers

You have to get Y alone on one side of the equals sign. Start by subtracting 6 from both sides (remember Inverse Operations?) Now you have 12y = -24 Now divide both sides by 12 and you get A. Y= -2!!!!! Hope this helps and, if you are able to do so, please mark Brainliest! Thanks!

In the Fibonacci Sequence, each term after the first two terms is the sum of the preceding two terms. If the first two terms are 1 and 1, then what is the tenth term?

Answers

If the first two terms are 1 and 1, then what is the tenth term?

Answer:

The 10th term will be 55

Explanation:

In the Fibonacci Sequence, we add the previous digits to get the next digit. So, here 1st term is 1.

First term= 1

Second term = 0+1= 1

Third term= 1+1=2

Fourth term= 1+2= 3

Fifth term= 2+3= 5

Sixth term= 3+5= 8

Seventh term= 5+8 = 13

Eighth term= 8+13= 21

Ninth term= 13+21= 34

Tenth term= 21+34 = 55

So, the 10th term is 55.

If you want to watch a 2 hour movie that starts at 4PM and you want to watch a 3 hour movie that starts at 2PM,there is a schedule conflict.

true, if you start the three hour movie at 2pm then you will be done with that one at five, while the other one starts at four so you would miss an hour of it

1/2 times 9/9=9/18
8/9 times 2/2=18/16

(9/18+16/18)/2=(25/18)/2=25/18 times 1/2=25/36
