Answer:
The cost in 2015 will be $283.45.
What is the reference point (t=0)?
d. The year 2005.
Step-by-step explanation:
The exponential growth model for the cost is the following:
In which C(t) is the cost after t years, 
is the initial cost and r is the decimal inflation rate
In this problem, we have that:
What will it cost in 2015 assuming the rate of inflation remains constant?
2015 is 10 years after 2005, so this is C(10).
The cost in 2015 will be $283.45.
The reference point is the year in which t = 0, so the year 2005.
1. 11663
2. 98
3. 46 days
4. 1121
5. 29 pounds
Set variables for the quantities we want to find. Let x = number of applesLet y = number of oranges Next, we use these variables to write equations that describes the whole story. Since the total price is $7.75 and each type of fruit has their own price, we can say 0.40x + 0.35y = 7.55 The other equation will represent the total number of fruits bought all together, as Mark mentioned. Once you have those equations, you solve the system using substitution and elimination methods to solve for the variables x and y.
Answer:
D. The geodesics connecting the North and South Poles intersect at both of the Poles
Step-by-step explanation:
Take the mixed number apart and have a whole number and a fraction
1+4 and 5/8 + 7/8
1+4=5
5/8 + 7/8 = 12/8
12/8 = 1 4/8
Add 5 to 1 4/8
5 + 1 4/8 = 6 4/8
1 5/8 + 4 7/8 = 6 4/8
In simplest term, the answer is also 6 1/2
-------------------------------------------------
Another way to solve it is by turning both 1 5/8 and 4 7/8 into improper fractions.
1 5/8 = 13/8
4 7/8 = 39/8
Add them.
13/8 + 39/8 = 52/8
Turn 52/8 into a mixed number.
52/8 = 6 4/8
Simplify it to get 6 1/2.
