A restaurant has a total of 30 tables which are of two

Anna007 [38]

Answer:

Total number of tables of first type = 23.

Total number of tables of second type = 7

Step-by-step explanation:

It is given that there are 30 tables in total and there are two types of tables.

Let's call the two seat tables, the first type as x and the second type as y.

∴ x + y = 30 ......(1)

Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:

2x + 5y = 81 .....(2)

To solve (1) & (2) Multiply (1) by 2 and subtract, we get:

y = 7

Substituting y = 7 in (1), we get x = 23.

∴ The number of tables of first kind = 23

The number of tables of second kind = 7

How do I do this. I don’t understand how to move place values

Drupady [299]

For this case we must indicate the value of the following expression, expressed in scientific notation:

$(1.2 * 10^{-3}) * (1.1 * 10^{8}) =$

We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:

$a ^ n * a ^ m = a ^ {n + m}$

Then, rewriting the expression we have:

$(1.2 * 1.1) * 10 ^{- 3 + 8} =\\1.32 * 10 ^ 5$

Answer:

$1.32 * 10 ^ 5$

Before a new video game is released, it is tested by a number of volunteer gamers. During testing, the experimental probability

sesenic [268]

Answer:

2000 players will complete the game with a perfect score.

Step-by-step explanation:

The testing phase tells us that $\frac{1}{500}$ is the probability that a person will finish with a perfect score.

This means 1 out of 500 people will be able to finish with perfect score.

Now,

the game is given to 1,000,000 (1 million) people and how much do we expect to finish with perfect score?? Simple! It would be $\frac{1}{500}$ the of 1 million!

We do the calculation shown below:

$\frac{1}{500}*1,000,000=2000$

So, 2000 players will complete the game with a perfect score.
