Given:
Multiply both sides by 3/2, we get
Cancel out the common multiples, we get
The solution of the given equation is
or
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 :)
Answer:
Step-by-step explanation:
We are told that the average human heart beats 
times per day and there are 
days in one year.
To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.
Now we will solve this problem using exponent properties.
Our answer is in scientific notation we can represent it in standard form as 
times.
Therefore, average human heart beats in one year or 41975000 times.
