A because you subtract 15from 20 and it =5 or 1/4
The answer is that it cannot be modeled with a rectangle.
Y=25*3^x
1170=25*3^x
25*3^x=1170
3^x=1170/25
3^x=46.8
Log10(3^x)=LOg10(46.8)
x*log10(3)=log10(46.8)
x=(log10/46.8))/(log10(3))
x=1.60724585307/0.47712125472
x=3.50067375233
x=3.50
Answer:
The system has infinite solutions
Step-by-step explanation:
For a system of two linear equations it is always true that if one equation is a linear combination of another, then the system will have infinite solutions.
Suppose we have the following system:
If there is a number n for which it is fulfilled that
Then the system has infinite solutions.
In this case the system is:
Observe that:
Then 
The system has infinite solutions
Answer:
Answer in explanation
Step-by-step explanation:
In this question, we would be examining the validity of some statements on the number π(pi)
π Is a whole number?
This is wrong, π is a fraction of 22 to 7 parts I.e 22/7
π Is double the radius?
This is wrong. It is the diameter that is double the radius
π Is approximately 3.14?
This is correct to an extent. The actual value in decimal is around 3.142857142857143 which makes the 3.14 somehow correct
π represents the ratio of the circumference of the circle to the diameter?
This is correct.
Mathematically, circumference C = π * diameter D
Hence C/D = π
π Is approximately 22/7?
This is correct. This is the ratio used for π
