Answer: 300/91
Step-by-step explanation:
1. Convert 4 1/3 to an improper fraction
13/3
2. Divide, using the keep, change, flip method to divide fractions
- Keep the first fraction the same (100/7)
- Change the division sign to a multiplication sign
- Flip the second fraction (13/3 -> 3/13)
3. Plug-in and evaluate
100/7 * 3/13
300/91
If you are looking for the solution as a mixed number, it is 3 27/91
4. Simplify, if applicable. This fraction cannot be simplified any further.
Answer:
21
Step-by-step explanation:
The first thing you need to do is add and then subtract
Answer: a) 800
b)
Step-by-step explanation:
The exponential growth function is represented by :-
, where A is initial value , b is the multiplicative rate of change and t is the time period.
Given : A bacteria culture starts with 100 bacteria and doubles in size every half hour.
i.e. A = 100 and b=2
Then, the exponential growth function to find the number of bacteris after t hours :_
At x=3
Hence, the there are 800 bacteria after 3 hours.
Let x and y be the number of pounds of apples and peaches, respectively. With this representation, two equations are generated.
(1) x + y = 165
(2) 1.75x + 2.50y = 337.50
Simultaneously solving for the values of x and y gives an answer of x = 100 and y = 65. Thus, Mo sold 65 pounds of peaches.
