Answer:

54 chaperones

Step-by-step explanation:

The basic idea behind this kind of question is that you want to keep the proportions equal. When there are 11 students, there are 2 chaperones. If there are now 297 students, how many chaperones must there be keep the proportions equal?

When answering this sort of question, you should construct an equation in which the basic ratio is equal to the proportions you're interested in. In this case:

2 chaperones / 11 students = X chaperones / 297 students

To find the value of X, you then cross-multiply and solve for X.

Cross-multiplying means that you multiply the numerator (top) on one side by the denominator (bottom) on the other, and vice versa.

Here,

2 chaperones x 297 students = 11 students x X chaperones

You then solve for X.

First, multiply the left side:

594 = 11X

Now, divide 594 / 11 to solve for X.

X = 54.

Because X stood for the number of chaperones, the answer is 54 chaperones.

A cube's side measures 6xy inches whet is the volume
liubo4ka [24]
For a cube, V = s^3.

The volume is the cube of the side length.

V = s^3

V = (6x^6y^8)^3

To raise a product to an exponent, raise each factor to the exponent.

V = (6^3) \times (x^6)^3 \times (y^8)^3

To raise a power to a power, multiply powers.

V = 216x^{18}y^{24}

The chart has been completed in the picture attached.

Step-by-step explanation:

Step 1:

It is given that the number of bacteria doubles every 6 hours.

So if there are 1 million now, in 6 hours there would be double that i.e. 2 million and it will go on.

Step 2:

As the first column says the number of 6-hour periods, the second column is the actual number of hours.

So the second column is multiples of 6 so the second column is filled with;

0, 6, 12, 18, 24, 30, 36, 42 and 48.

Step 3:

The current population is calculated by multiplying the previous population by 2.

For 0 hours, the population = 3 million,

For 6 hours, the population = 2(3) = 6 million,

For 12 hours, the population = 2(6) = 12 million,

For 18 hours, the population = 2(12) = 24 million,

For 24 hours, the population = 2(24) = 48 million,

For 30 hours, the population = 2(48) = 96 million,

For 36 hours, the population = 2(96) = 192 million,

For 42 hours, the population = 2(192) = 384 million, and

For 48 hours, the population = 2(384) = 768 million.

So at the end of 48 hours, there will be approximately 768 million bacteria on the pinhead.
