In one year, the CPI increased from 106.3 to 108.9. How much money was required at the end of the year in order to have the same purchasing power as $1,000 at the beginning?
Answers
Based on the increase in CPI, the amount that would be required at year end to have the same purchasing power at the beginning of the year is $1,024.46.
How to find the change in purchasing power?First, find the inflation rate:
= (Current CPI - Beginning CPI) / Beginning CPI
= (108.9 - 106.3) / 106.3
= 2.446%
This means that the amount of money at the beginning of the year has lost a value of 2.446%.
In order to remain the same as the value of $1,000, a person would need:
= 1,000 x (1 + 2.446%)
= $1,024.46

(Note 1.25 cubic feet = 1 bushel)
Answers
Answer:
Volume = 2268 ft³
1814.4 bushels of corn
Explanation:
The volume of the corn crib can be calculated as:
Volume = Length x Width x Height
Then, the volume is equal to:
Volume = 21 ft x 9 ft x 12 ft
Volume = 2268 ft³
Finally, to know the number of bushels of corn that can be stored, we need to divide the volume of the corn crib by the volume of each bushel of corn. So:
[tex]\frac{2268ft^3}{1.25ft^3}=1814.4\text{ bushels of corn}[/tex]Therefore, the volume of the corn crib is 2268 ft³ and it can store 1814.4 bushels of corn.

The coordinates of a point on a circle with radius 18 corresponding to an angle of 190° are (-17.73, -3.13).
What is transforming coordinates?
Polar coordinates (r,θ) are transformed into Cartesian coordinates (x, y) using the formulas x = r cos(θ), and y = r sin(θ).
This problem is under the concept of transforming polar coordinates (r,θ) to cartesian coordinates (x, y).
For this problem the polar coordinates are r = 18 and θ = 190°.
Convert these polar coordinates into a cartesian coordinates as,
x = r cos(θ) = 18 cos(190°) = -17.73
y = r sin(θ) = 18 sin(190°) = -3.13

Write a system of equations to represent this situation let x represent the number of Lucky Horseshoe Stables $12 equipment fee plus hour 259 Calories What is the solution to the system of equations? What does the solution represent?
Answers
8A) Let x represent the number of hours of horseback riding.
Let y represent the total cost of the package
If Lucky horseshoe stables is used for x hours, the equation for the total cost would be
y = 7x + 12
If Go galloping horseshoe rides is used for x hours, the equation for the total cost would be
y = 10x + 6
Thus, the equations are
y = 7x + 12
y = 10x + 6
B) To solve the system of equations, we would substitute the first equation into the second equation. It becomes
7x + 12 = 10x + 6
10x - 7x = 12 - 6
3x = 6
x = 6/3
x = 2
y = 7x + 12 = 7 * 2 + 12
y = 14 + 12
y = 26
The solution of the system of equations is (2, 26)

so fill in 6 wherever you see a y.
2(3x - 6) - 5y
fill in -2 for x and 6 for y.

Work on parentheses first. Multiply before adding or subtracting.

A road sign is in the shape of a regular pentagon. What is the measure of each angle on the sign? Round to the nearest tenth. 540 252 54 Od 108
Answers
Internal angles of a polygon
The triangle has n=3 sides, and the sum of its internal angles is 180°
The rectangle has n=4 sides, and the sumo of its internal angles is 360°
There is a general formula to calculate the sum of the internal angles of any polygon of n sides:
Sum = 180° ( n -2 )
For a pentagon (n=5), the sum of angles is:
Sum = 180° ( 5 -2 ) = 180° * 3 = 540°
We are required to find the measure of each internal angle. Since the pentagon is regular, all of its internal angles measure the same, thus:
The measure of each angle = 540° / 5 = 108°

The number of solutions that this equation have is: A. zero solutions.
What are zero solution?Generally speaking, an equation is said to have zero solution or no solution when the left hand side and right hand side of the equation are not the same or equal. This ultimately implies that, an equation would have zero solution or no solution when both sides of the equal sign are not the same and the variables cancel out.
How to determine the number of solutions?In order to determine the number of solutions that this equation have, we would simplify the equation by opening the bracket and then compare both sides of the equation as follows:
6(c+4) = 6c + 30
6c + 24 = 6c + 30
