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:
b = 10
Step-by-step explanation:
a) Solve by inspection. b=10 makes both fractions equal to 1.
Both the numerator and denominator of the fraction on the right are 2 greater than those of the fraction on the left. The fractions will be equal when numerator and denominator are equal.
__
b) Multiply by 60 and solve in the usual way.
6b = 5(b+2)
b = 10 . . . . . . . . . . subtract 5b
__
c) Expand the fraction on the right, subtract the variable term.
b/10 = b/12 + 2/12
b(1/10 - 1/12) = 1/6
b/60 = 1/6 . . . . simplify
b = 60/6 = 10 . . . . multiply by 60

<em>Comment on the question</em>
There is no "y", so you cannot solve for y. This is another example of poor quality control (editing) of math curriculum materials. It is my sincere wish that you not have to put up with that. Math is tough enough without this added confusion.
Answer:
Janice needs 1$ more.
Step-by-step explanation:
Multiply both price rates by 5.
(.80x5)+(1.40x5)
(4)+(7)
Add to find the total cost.
11$
Subtract the cost from the budget.
11-10=-1$
Janice needs 1$ more.
These are independent so probability of one does not affect the other.
1. P = 1/8 * 1/6 = 1/48
2. P=1/8 * 3/6 = 3/48 or 1/16
3. P= 4/8 * 1/6 = 4/48 or 1/12
4. P= 4/8 * 3/6 = 12/48 or 1/4
5. P= 5/8 * 2/6 = 10/48 or 5/24
6. P= 4/8 * 2/6 = 8/48 or 1/6
