Frank can mow lawns at a constant rate of 6/5 lawns per hour. what is the ratio of lawns to hours?
1 answer:
Answer:
6 : 5
Step-by-step explanation:
Rate =
But Rate is also equal to number of lawns mowed in a certain amount of time.
Since ratio should always be in terms of simple whole numbers.
If 6/5 lawns are mowed in 1 hour, then,
6 lawns will be mowed in:
=
= 5 hours.
therefore, 6 laws will be mowed in 5 hours.

Answer: b.14
Step-by-step explanation:
We have two shelves, the top shelf and the bottom shelf
.
Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:
(1)
Then, we are told there are 12 books on the bottom shelf:
(2)
Substituting (2) in (1):
(3)
(4)
(5) This is the number of books on the top shelf
Hence, the correct option is b.
Answer: A) The initial number of bacteria is 350.
Step-by-step explanation:
Exponential growth equation: , where A=Initial value, r= growth rate. (i)
Given: A bacteria sample can be modeled by the function which gives the number of bacteria in the sample at the end of x days.
Here,
Compare this equation to (i) , we get A = 350 and r= 0.20 = 20% (growth rate)
So, the best interpretation of one of the values in this function are:
A) The initial number of bacteria is 350.
