Write the prime factorization of 18. Use exponents when appropriate and order the factors from least to greatest (for example, 
Vsevolod [243]
Prime factorization is when the numbers are divided until they cannot be divided anymore.

For example, the number 18.

18/2 = 9

9/3 = 3

So the prime factorization is 2,3,3

As it says use exponents: There are 2 threes. 3 x 3 is the same as 3²

3² x 2 should be your answer

hope this helps

Dirrens' oven only measures in degree Fahrenheit (°f).show that 200°C would be 392°F.
Ainat [17]

I think you shouldn't memorize any formula to solve it. But you should know that on the fahrenheit thermometer freezing point is 32 and the boiling point is 212. And in celcius, it is 0 and 100. So we can make the inference that changing 100 units in celcius corresponds to a change of 180 units in fahrenheit. Thus, we should ask that if celcius increase from 0 to 200, what would happen to fahrenheit.

Basic math:

While celcius increase 100, fahrenheit increase 180,

While celcius increase 200, fahreinheit increase 360.

And you shouldn't forget that fahrenheit's freezing point is 32.

32+increase(360)=392

What is the average (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive?
NeX [460]

Answer:

letter C: 100

Step-by-step explanation:

This problem can be configured as an arithmetic progression:

The first value is 10, the ratio is also 10 (the multiples of ten are 20, 30, 40, ...) and the number of terms is 19 (10, 20, 30, ... , 180, 190 -> total of 19 numbers).

So, we can use the following formula to calculate the sum of all these numbers:

Sn = n(a1 + an) /2

where Sn is the sum, n is the number of terms, a1 is the first term and an is the last one.

The result we want is the average of the sum, so we need to divide Sn by n:

Average = Sn/n = n(a1 + an) /2n = (a1 + an) /2 = (10+190)/2 = 200/2 = 100

The correct option is letter C.

Solve r = cs/d for c
Nady [450]
r=\frac{cs}{d}\\\\\frac{cs}{d}=r\ \ \ \ |multiply\ both\ sides\ by\ d\\\\cs=dr\ \ \ \ \ \ |divide\ both\ sides\ by\ s\\\\\boxed{c=\frac{dr}{s}}
