For glass, calculate the average rate of change between 1970 and 1980. Then interpret what this value means.
a.
From 1970 to 1980, the number of pounds of glass per person per day decreased by 0.002 per year.
c.
From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.
b.
From 1970 to 1980, the number of pounds of glass per person per day decreased by 0.11 per year.
d.
From 1970 to 1980, the number of pounds of glass per person per day increased by 0.11 per year.
The correct option regarding the average rate of change for glass is given by:
c. From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.
What is the average rate of change of a function?It is given by the change in the output divided by the change in the input.
Looking at the table, in the 10 years from 1970 to 1980, the amount of glass changed from 0.34 pounds to 0.36 pounds, hence the rate is given by:
r = (0.36 - 0.34)/10 = 0.02/10 = 0.002.
Which means that option c is correct.

Answer:
(b) 7720 mm² of paper
Step-by-step explanation:
The central horizontal rectangle of the net is 80 mm high and ...
40 + 5.5 + 40 + 5.5 = 91
mm long. Its area 9 is ...
(80 mm)(91 mm) = 7280 mm²
__
The two pieces of the net not accounted for above are the "flaps" above and below the central rectangle. Each of those two has an area of 40 mm by 5.5 mm, so their total area is ...
2(40 mm)(5.5 mm) = 440 mm²
Then the area of paper needed for the wrapper is ...
total area = 7280 mm² + 440 mm²
total area = 7720 mm²

Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G (1,3) H (4,3) J (5,1) and K (2,1)
Answer: (3,2)
Step-by-step explanation: Diagonal is a line connecting two opposite points of a form. In parallelograms, there two diagonals and they bisect each other, i.e., the point where the diagonals meet divide them into two segments with the same measure. In short, diagonals meet at their midpoint.
The way to determine midpoint is given by
(x,y) = [tex]{\frac{x_{1}+x_{2}}{2} },\frac{y_{1}+y_{2}}{2}[/tex]
(x,y) = [tex]{\frac{1+5}{2} },\frac{3+1}{2}[/tex]
(x,y) = (3,2)
The coordinates where diagonals of parallelogram GHJK intersect are (3,2).

Answer:
wheres the graph which is provided by the question?
Step-by-step explanation:
The y-intercept of George's equation is positive. Then George's equation is correct.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Chrissie says that the equation of the line shown on the graph is y = 1/2x -5. George says that the equation of the line is y = 1/2x + 5.
From the graph, the y-intercept of George's equation is positive then George's equation is correct.

Step-by-step explanation:
Answer:
C. 35 sq. units
Step-by-step explanation:
in order to find the area of a triangle you have to use the formula
1/2 b h
b as in base
h as in height
so if we use the measurements on the triangle and we plug that in we will get
1/2 x 14 (the base) x 5 (the height)
therefore giving us 35 sq. units.
