There are a total of 128 teams at the start of a citywide 3-on-3 basketball tournament. half the teams are eliminated after each round. write and solve an exponential equation to determine after which round, x, there are 16 teams left.

'after the third round'.

Step-by-step explanation:

Let T be the number of teams after n rounds.

T=128\times(\frac{1}{2})^{n}

When T = 16, we get:16=128\times(\frac{1}{2})^{n}

Dividing both sides by 128, we get:

\frac{1}{8}=(\frac{1}{2})^{n}

Therefore n = 3

The answer is 'after the third round'.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
