Janine has 93 beads. She uses 7 beads for each bracelet. She makes as many bracelets as possible. How many beads will Janine have left over?

The difference between constructing and drawing geometric figures is as follows:

To construct geometric figure you use many tools like protractor, compass, ruler, scale, square, among others. So you need an accurate representation of the geometric figure. On the other hand, to draw a geometric figure you only need a pencil to do that. You don't need an accurate representation of the geometric figure.

A real-world example of each:

Think about an civil engineer who is constructing a building. He would need many tools to do that. In fact, he would need an building which is an accurate representation of the drawings he made using a software. He would need the accurate measurements and the correct location of each characteristic points of the building. So, this is the construction. On the other hand, when starting with the project, the civil engineer maybe took a paper and began drawing an sketch of his building, he only needed a pencil to do that, so this is the drawing made by hand.

The value of y is 5

Given,

2x+z=2y

2x+2y+z=20

Now,

From equation substitute the value of 2x,

2x = 2y -z

substitute the value in second equation,

2y -z + 2y + z = 20

Now solve the terms with like variables,

4y = 20

y = 5

Step-by-step explanation:

I can help :D

For this case, what we must do is solve the following system of equations:  tan (50) = h / x  tan (40) = h / (x + 50)  

Solving the system we have:  (x + 50) * tan (40) = h  (x) * tan (50) = h  

Matching:  (x + 50) * tan (40) = (x) * tan (50)  

Rewriting:  x (tan (50) - tan (40)) = 50 * tan (40)  x = 50 * tan (40) / (tan (50) - tan (40))  x = 118.9692621  

Substituting:  h = (x) * tan (50)  h = (118.9692621) * tan (50)  h = 141.7820455
