Step-by-step explanation:
1 acre times 2 1/2 lb per 1/8 acre
1 * ( 2 1/2 / 1/8) = 20 pounds
The number of entries in the domain and range of a function can be different. Some inputs in the domain may have the same output in the range, or some outputs in the range may have no corresponding inputs in the domain.
In a function, the number of entries in the domain and range can be different. This happens when there are multiple inputs that map to the same output or when there are outputs with no corresponding inputs.
For example, consider the function f(x) = . The domain can be any real number, but the range is only non-negative real numbers (including zero). So, there are more entries in the domain than in the range.
When this is the case, it means that some inputs in the domain have the same output in the range, or some outputs in the range have no corresponding inputs in the domain.

Answer:
60 minutes
Step-by-step explanation:
Given the schedule above :
Red line arrives every 4 minutes
Blue line arrives every 5 minutes
Yellow line arrives every 6 minutes
All three just arrives at the train station ; when next will they all arrive at the train station at the same time.
Obtain the lowest common multiple of each arrov time :
Lowest common multiple of 4, 5, 6
_2___4___5___6
_2___2___5___3
_3___1___ 5 __ 3
_5___1___ 5 __ 1
_____1 ___1 ___1
Hence, lowest common multiple :(2 * 2 * 3 * 5) = 60
Hemce, they all arrive at the train station at the same time after 60 minutes
Answer:
3.54 and 1.04
Step-by-step explanation:
Given:
Two towns are 1,100 miles apart.
A group of hikers Starts from each town and walks down the trail toward each other..
They meet after a total hiking time of 240 hours.
If one group travels 2 1/2 mile per hour slower than the other group.
Question asked:
Find the rate of each group.
Solution:
Let speed of faster hiker =
Speed of slower hiker =
As we know:
Total distance between two town = Total combined speed of both hikers Total combined time taken
Speed of faster hiker = = 3.54 miles per hour.
Speed of slower hiker = =
Therefore, speed of faster hiker is 3.54 miles per hour and speed of slower hiker is 1.04 miles per hour.
The original price of the play equipment is $2000, if the price of it has been reduced by 25% to become $1500.
This question is about calculating the original price of a product considering a discount percentage. If the reduced price of the play equipment is $1500 after a 25% discount, to find the original price, you need to consider the reduced price as 75% of the original price (since the price is reduced by 25% from the original).
Therefore, you can set up the equation like this: 0.75 × original price = $1500. To find the original price, divide both sides of the equation by 0.75. The calculation would be $1500 / 0.75 = $2000. Thus, the original price of the play equipment is $2000.
