Answer:
48 square units
Step-by-step explanation:
Let the length of the rectangle be x units.
By Pythagoras theorem:
Length of rectangle = 8 units
Area of rectangle
= Length * width
= 8 * 6
= 48 square units
Answer:
If the kid walks for the dotted line, the distance is 36ft.
Now, you can see that this is a triangle rectangle, then we must have that:
x^2 + (x + 6)^2 = 36^2 (the Pythagorean theorem)
Now we must solve this for x.
x^2 + x^2 + 2*6*x + 36 = 36^2
2*x^2 + 12*x -1260 = 0
The solutions for this equation are:
the solutions are:
x = (-12 - 101.1)/4 = -28.78
x = (-12 + 101.1)/4 = 22.3
Then we have x = 22.3 ft
The lenght of the path following the cathetus is:
D = x + x + 6 = 2*22.3ft + 6ft = 50.6ft
Then the difference between the distances is:
Diff = 50.6ft -36ft = 14.6ft
Answer:
-27/5
Step-by-step explanation:
[x*4 + 3(x-1)]\12=2+x
4x+ 3x -3 =12(2+x)
7x -3 =24 +12x
7x-12x =24 +3
-5x =27
x = (-27/5)
Answer:
The answer is d. categorical data
Step-by-step explanation: The reason is because categorical data are used to represent characteristics such as a person's state, religion, country, marital status, gender, etc.
Other names for categorical data are Qualitative data or Yes/No data.
The reason why Arithmetic operations can not be used for these kind of data is because the data are not numerical. For example, you can not add or subtract genders, neither can you multiply religions, and so on.
