Let us consider the number of edges = x
we know that a triangle will have 3 edges and a square will have 4 edges. Using this details we can form an equation.
3x + 4x = 8484
7x = 8484
x = 8484/7
= 1212
Then
Number of square tiles = 1212/4
= 303
So there are 303 square tiles in the box. I hope the procedure is clear enough for your understanding. You can always use this method for solving similar problems.
Answer:
60 degrees
Step-by-step explanation:
a+b+c= 180 degrees therefore 5x + x + 3x = 9x
9x=180 (divide) --> x=20
since c = 3x substitute in 20 for x --> 3(20) = 60 degrees for angle c
Answer:
Slope = ⅚
Step-by-step explanation:
Using the coordinates of two points in the graph, say (0, 0) and (6, 5).
The slope of the graph is ⅚.
The slope represents the ratio of proportion of yellow paint to blue paint that must be mixed together to produce green paint.
This means, to make green paint, for every 5 parts of yellow paint, 6 parts of blue paint is required to be added as a mixture.
The equation is <span>h(t) = -16t2 + 1600</span>.
When the package hits the ground, h(t) = 0: 0 = -16t2 + 1600 To solve by factoring: 0 = -16(t2-100)0 = -16(t+10)(t-10) t = -10 and +10 seconds.
Since we aren't interested in negative time, t = 10 seconds.
