Answer: 5.3
Step-by-step explanation: Do 9.8 (Friend swim depth) - 4.5 (dolphin jump height) to get your answer.
I know for sure it’s not B or D so I believe it is A.
Answer:
It will take them 3.43 hours.
Step-by-step explanation:
Let T denote the total cookies that need to be cocked. Observe that:
- If Rosanne finishes the cookies in 6 hours, that means that she can make
cookies per hour. - If Dorothy finishes the cookies in 8 hours, that means that she can make
cookies per hour.
Then, by 1) and 2), if they work together would we able to make

cookies per hour.
Therefore, in order to finish the T cookies they will need 
Answer: 5=log_{2}(32)5=log
2
(32)
Step-by-step explanation:
1. By definition, you have if y=b^{x}y=b
x
, then x=log_{b}(y)x=log
b
(y)
2. Keeping this on mind, you must follow the proccedure shown below:
- You have that:
2^{5}=322
5
=32
Where:
\begin{lgathered}x=5\\y=32\\b=2\end{lgathered}
x=5
y=32
b=2
- Substitute values into x=log_{b}(y)x=log
b
(y) . Then, you obtain:
5=log_{2}(32)5=log
