Answer:
Rate of Change = -77.9 feet/year
My interpretation: "Is Bad."
Step-by-step explanation:
The rate of change is the number of feet that Lake Powell dropped, divided by the number of years the drop took place. We want a value with a unit of feet/year.
<u>Year</u> <u>Feet</u>
1999 3893
2005 3425.6
<u>Change</u>
Year = (2005 - 1999) or 6 years
Feet = (3425.6 - 3893) or -467.4 feet
Rate of Change = (-467.4 feet)/(6 years)
Rate of Change = -77.9 feet/year
=======================
FYI: Lake Powell is 22.39 feet lower today (June 23, 2022) than it was 1 year ago.
Answer:
Length= 50
Width=17
Step-by-step explanation:
length= n+8
Since n= 42, Just plug it in. So it would be 42+8 which is 50 for the length
Widith: 1/2n-4
basically since N is given for 42, you do 1/2 multipied by 42 which is 21.
Since you also have to subtract 4 inches it would be 17 for the length
1 inch = 2.54 cm
3 inches = 3 * 2.54 = 7.62 cm
Answer:
3
Step-by-step explanation:
21x + 6 = 3x + 60 subtract 3x from both sides
(21x-3x) + 6 = 60
18x + 6 = 60 subtract 6 from both sides
18x= 60-6
18x= 54 divide by 18
x =3
