Answer:
length/width = 1/1 = 1
Step-by-step explanation:
(3x)(2x) = 12150
6x^2 = 12150
x^2 = 2025
x = 45
Length is 135 ft, width is 90 ft, perimeter is 450 ft
Geometric mean: 135 : x :: x : 90
x^2 = 12150
x = 45√6
The second rectangular piece of land is a square !
length/width = 1/1 = 1
Answer:
I can't see the graph.....
Step-by-step explanation:
Answer:
Y = 3/4x - 2
Step-by-step explanation:
Slope = (1 - - 5)/(4 - - 4 =6/8 = 3/4
b = -5 - (3/4)(-4)
b = -5 + 3 = -2
y = 3/4x - 2
Answers:
- A) The equation is d = 2t
- B) Independent variable = time; dependent variable = amount of cookies
=========================================================
Explanation:
The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.
The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.
The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.
