Vladimir79 [104]

Answer

The answer to your question is  2 x 2 x 5 x 5 or 2² 5²

Step-by-step explanation:

Process

1.- To find the prime factors of a number, we must divide the number by prime numbers like 2, 3, 5, 7, 11, etc. starting from the lowest number.

                         100     2

                           50     2

                           25     5

                             5      5

                              1

Then  100 = 2 x 2 x 5 x 5 or 2² 5²

Dorothy types 120 words per minute. How many words does Dorothy type in 1.75 minutes?
nirvana33 [79]
As you are looking for 1.75 minutes (or 105 seconds), the best thing to do is to find how many words she can type in 0.25 minutes (this is a quarter, and you can divide 1.75 by this). To find a quarter, you have to divide by 4, 120/4= 30. Therefore, every 15 seconds, Dorothy can type 30 words. As you've got 105 seconds, divide this by 15, and this gives you 7. Then multiply 30 by 7, and this gives you 210.
Dorothy can type 210 words in 1.75 minutes
Hope this helps :)

3(2^x) = 6^2x <br>How do you solve this?
iragen [17]
3(2^x)=6^{2x}
3(2^x)=(3\times2)^{2x}
3(2^x)=3^{2x}2^{2x}
\ln(3(2^x))=\ln(3^{2x}2^{2x})
\ln3+\ln2^x=\ln3^{2x}+\ln2^{2x}
\ln3+x\ln2=2x\ln3+2x\ln2
\ln3=2x\ln3+2x\ln2-x\ln2
\ln3=x(2\ln3+\ln2)
x=\dfrac{\ln3}{2\ln3+\ln2}
