Well, scence you don't know how many quarters are in a stack of 5mm, ill give a variable answer...there's 10x as many quarters in the stack of cm than the stack of millimeters, because 5mm=1/2 cm, and 5/.5=10
Start with the formula: h=k \t
Substitute the values :<span> 2=k\65
</span><span>
then solve for</span> k: k=130
Answer:
Area of the self will be 
Step-by-step explanation:
We have given that self is 4 feet wide and 
feet deep
So length pf the shelf l = feet
And width = 4 feet
We have to find the area of the self
We know that area is given by
Area = length × width
So area of the self will be
Answer:
21.73
Step-by-step explanation:
calculator
(a) Answer: One solution.
Explanation: two lines that have same slope with opposite sign will necessarily cross each other at a single point, as one is "pointing uphill" and the other "downhill."
(b) Answer: Infinitely many solutions.
Explanation:
2x + 3y = 5.5
4x + 6y = 11 | divide by 2
-->
2x + 3y = 5.5
2x + 3y = 5.5
--> equations are identical.
2x + 3y = 2x + 3y
so any (x,y) will satisfy this equation. This means infinitely many solutions.
(c) Answer: One solution
Explanation:
Continuing the two lines it becomes obvious they will cross at one point (the solution)
(d) Answer: No solution
Explanation: If the two lines are parallel, they will never cross (by definition of "parallel"). Therefore there will be no solution to the corresponding linear system.
