Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so will become
.
Now we do 75 times /
So, there are 125 total pages in the book.

Answer:
Step-by-step explanation:
When you have exponents above a like term and they are being multiplied together, you add them.
For example:
So let's group like terms in the numerator:
We can add terms like in the example.
Let's rearrange the denominator.
Now we have:
Cancel like terms
4/8 = 1/2
= 1 So it cancels
= s Since s is raised to the -1 it goes on top and becomes s.
Now we combine everything back together:
Answer:
Yes
Step-by-step explanation:
the function that gives the alcohol level is:
where x is the number of hours.
we need to know if after 4 hours an average person is legally drunk, thus:
and we substitute this in the function:
solving these operations we obtain:
the alcohol level after 4 hours is 3.24.
Since a person is considered to be legally drunk if the level exceeds 1.5, and we obtained 3.24 which is greater than 1.5, a person who has been drinking for 4 hours under the conditions indicated by the problem would be considered legally drunk.
