Answer:
The perimeter of the larger sign : 144*1,25= 180 inches
Side of the triangle= 180/3= 60 inches
square of the height= 60^(2) - 30^(2)= 2700 ( Pythagoras' theorem)
height= square root ( 2700)= 51,96
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Let be "x" the lenght in feet of rope that you can buy with 30 dollars.
According to the information provided in the exercise, you can buy a piece of rope of 2 feet with 20 cents.
Remember that 
Knowing this, you can write the following proportion:
FInally, solving for "x", you get this result:
Answer:
sensitivity analysis
Step-by-step explanation:
The ability to examine the variability of a solution due to changes in the formulation of a problem is an important part of the analysis of the results. This type of analysis is called Sensitivity analysis.
It helps us figure out the robustness of a system or model in the presence of an uncertainty
It also increases the relationship between the inputs and outputs from the system or model
Our distance is x
We know each week she rides a total distance greater than 10 km and less than or equal to 30 km
We can write this like the following:
x > 10
x <= 30
It also tells us the distance is always an even number and a multiple of 3. Ask your self, what are some numbers between 10 and 30 and is a multiple of 3.
12, 18, 24 and 30
So the possible distances are 12, 18, 24, 30
Notice each number is an even number and you can divide the number by 3 evenly so they are numbers with 3 being a multiple.
