Identify the correct solution for the expression:<br> −10 + (−16) − 10

DiKsa [7]

To convert a number from scientific notation to standard form, consider 1.5625 x 10^4. First, focus on the exponential number, which is 10^4. Multiply the base number, which is 10, by itself the number of times indicated by the exponent, which is four. You would do that like this:

10 x 10 x 10 x 10 = 10, 000

Plug the product -- which is 10,000 -- into the original equation to get this:

1.5625 x 10,000 = 15, 625

Therefore, the standard form of this number is 15,625.

For a number in expanded form, convert the number, using basic addition. For example, consider the expanded number 10,000 + 2000 + 100 + 10 + 9. Add up these numbers to get the standard form. Your equation would look like this:

10,000 + 2,000 + 100 + 10 + 9 = 12,119

Therefore, the standard form of the number is 12,119.

Use prime factorization to reduce each fraction 1. 22/165 2. 35/210

yKpoI14uk [10]

Lets find the prime factorization of 22, 165, 35 and 210. Prime factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number.

The prime factorization of the number 22 is:

$22=2\times11$

Similarly, for 165, 35 and 210 we have

$\begin{gathered} 165=3\times5\times11 \\ 35=5\times7 \\ 210=2\times3\times5\times7 \end{gathered}$

Then, we can solve the given questions.

Question 1.

$\frac{22}{165}=\frac{2\times11}{3\times5\times11}$

so we can cancel out the number 11 and get

$\frac{22}{165}=\frac{2}{3\times5}=\frac{2}{15}$

Then, the answer is

$\frac{2}{15}$

Question 2.

$\frac{35}{210}=\frac{5\times7}{2\times3\times5\times7}$

and we can cancel out the number 5 and 7, then we obtain

$\frac{35}{210}=\frac{1}{2\times3}$

then, the answer is

$\frac{1}{6}$

RoseWind [281]

Okay so 3 hours*60 minutes= 180
45 minutes?
so 180/45=4
so in three hours she has had four sessions
and in six it will be 8
in nine it will be 12
and in 12 it'll be 16
sixteen sessions
hope i am right
