Answer:
B
Step-by-step explanation:
I added all of then and then subtracted 47 from the 50.
b must be equal to -6 for infinitely many solutions for system of equations and
<u>Solution:
</u>
Need to calculate value of b so that given system of equations have an infinite number of solutions
Let us bring the equations in same form for sake of simplicity in comparison
Now we have two equations
Let us first see what is requirement for system of equations have an infinite number of solutions
If and are two equation
then the given system of equation has no infinitely many solutions.
In our case,
As for infinitely many solutions
Hence b must be equal to -6 for infinitely many solutions for system of equations and
Answer:
The approximated height of the tree is of 112 meters.
Step-by-step explanation:
The height of a tree with a base diameter of d meters is approximated by the following formula:
In this question:
Base diameter of 3.2m, so , and the height is in meters.
The approximated height of the tree is of 112 meters.
The answer is:
212/100
=(200/100)+(12/100)
=2.00+0.12
=2.12
