D.)18 in. by 27 in.
Answer:
B.)36 in. by 54 in.
Step-by-step explanation:
It's a 1 to 6 ratio, so I did the dimensions(6 and 9) and multiplied each by 6.
y = –6x+2

Valerian split up the area of a rectangle to help her solve a division equation.
area model split into 2 parts, each with a width of 9 units. From top to bottom the parts have a height of 800 units and an area of 7,200 square units; a height of 54 units and an area of 486 square units.
Thomas decides to use the method of proportions and similar
triangles to find the height of a lamppost. He measures the length of
the post's shadow and finds it is 5 feet long. Then, he holds a 1-foot
ruler perpendicular to the ground and finds that it casts a 2-inch
shadow. How tall is the lamppost?
a. 2.5 ft c. 30 ft
b. 12 ft d. 60 ft
Answer:
The lamppost is 30 ft tall.
Step-by-step explanation:
You need to draw a diagram of the problem. Refer to attachment.
Now you need to convert the measurements that are in feet to in. The 1 foot ruler is now 12 in. and the 5 foot post's shadow is now 60 in.
The next step is to create a proportion between both angles. [tex]\frac{x}{1} =\frac{60}{2}[/tex]
x over 1 is simplified to x and 60 divided by 2 is just 30. So the lamppost is 30 ft tall.
Hope that helped. :)

The table shows the approximate height of a football after it is kicked. Tell whether the rates of change for successive time intervals are constant or variable
Answer: 36, 13, -10
The rates of change are variable.
Step-by-step explanation:
The rates of changes of the heights of a football after it is kicked with respect to the time for this case are 34, 12 and -10 . The rates of changes are variable.
What is a variable and a constant?A variable is a quantity that changes in its value, but a constant remains fixed.
How to measure the rate of change of something as some other value changes?Suppose that we have to measure the rate of change of y as x changes, then we have:
[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where we have
[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]
Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)
For this case, we get the rates as:
For rate between first two values,
[tex]Rate_1 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{17-0}{0.5-0} = 34[/tex]
For rate between second two values,
[tex]Rate_2 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{30-17}{1.5-0.5} = 13[/tex]
For rate between third two values,
[tex]Rate_3 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{25-30}{2-1.5} = -10[/tex]
We see that the rate of change of height of the football considered with respect to time is changing, so its a variable.
Thus, the rates of changes of the heights of a football after it is kicked with respect to the time for this case are 34, 12 and -10 . The rates of changes are variable.
