Refer to Table 24-1. If Year 1 is the base year, then the inflation rate in Year 2 was
a. 2.10 percent.
b. 1.40 percent.
c. –3.90 percent.
d. –1.40 percent.
Answer:
c
Step-by-step explanation:
If Year 1 is the base year, then the inflation rate in Year 2 was 2.10 percent. The correct option is a.
What is inflation rate?Inflation rate is the rate at which the general level of prices for goods and services in an economy is increasing over a certain period of time, typically one year.
To calculate the inflation rate, we need to compare the price level in Year 2 to the price level in Year 1.
Using the data from Table 24-1, we can see that the price index in Year 2 is 102.1 and the price index in Year 1 is 100.0.
The inflation rate can be calculated using the following formula:
Inflation rate = (Price index in Year 2 - Price index in Year 1) / Price index in Year 1 * 100%
Plugging in the values, we get:
Inflation rate = (102.1 - 100.0) / 100.0 * 100%
Inflation rate = 2.1%
Therefore, the correct answer is (a) 2.10 percent.

Parallelogram MNOP with vertices M(1, 7),
N(8, 5), O(4, 2), and P(-3, 4): and it rotates 180° What will be the new coordinates
The new coordinates are M'(-1, -7), N'(-8, -5), O'(-4, -2), and P'(3, -4)
What is a 180 degrees rotation?A 180 degrees rotation denoted by R(180, 0) is a rotation that has the same effect as the 180 degrees counterclockwise of a figure.
And it has the algebraic rule of its rotation to be changed from (x, y) to (-x, -y) i.e (x, y) ⇒ (-x, -y)
How to determine the image of the rotation?The coordinates of the parallelogram are given as
M(1, 7), N(8, 5), O(4, 2), and P(-3, 4)
The rotation is given as 180° rotation
As mentioned above,
We have (x, y) ⇒ (-x, -y)
Substitute M(1, 7), N(8, 5), O(4, 2), and P(-3, 4) in (x, y) ⇒ (-x, -y)
So, we have
M'(-1, -7), N'(-8, -5), O'(-4, -2), and P'(3, -4)
Hence, the coordinates of the image are M'(-1, -7), N'(-8, -5), O'(-4, -2), and P'(3, -4)

Ben measures the length of the street he lives on to be 80 000 cm. What is the street length in kilometres?
(1km 100 000 cm)
Answer:
.8Km
Step-by-step explanation:
There is exactly 100,000 CM in every KM, if someone such as Ben was to measure out 80,000, to convert to KM you'd take the given value and divide by the appropriate values.
80,000cm / 100,000cm = .8 KM

When the greatest common divisor and least common multiple of two integers are multiplied, the product is 180. How many different values could be the greatest common divisor of the two integers
The different values that could be be the greatest common divisor of the two integers are; 1, 2, 3, 4, 6
How to find the greatest common divisor?
Let the numbers be a, b. Thus, the product of the GCD(a, b) and the LCM(a, b) will be ab.
Now, for us to get something to be a factor of the GCD we need to make it be a factor of both a, b. Thus, its' square must be a factor of 180.
Therefore, the only numbers whose square is a factor of 1800 are 1, 2, 3, 4, 6 and as such they are the only GCDs possible.

A worker at a snack stand opened a new box of spoons. The first day, the worker used 25 spoons from the box. The second day, the worker used 15% of the remaining spoons in the box. A total of 140 spoons were used on the second day. What was the original number of spoons in the box before any spoons were used?
The original number of spoons is 958
Let the total number of spoon be x.
The first day, 25 spoons were removed.
So, the remaining spoon (r) is:
\(r =x -25\)
15% of the remaining spoon were used.
So, we have:
\(15\% \times r =15\% \times (x -25)\)
This 15% represents 140 spoons.
So, the equation becomes
\(15\% \times (x -25) = 140\)
Express 15% as decimal
\(0.15 \times (x -25) = 140\)
Divide both sides by 0.15
\((x -25) = 933\)
Remove brackets
\(x -25 = 933\)
Add 25 to both sides
\(x= 958\)
Hence, the original number of spoons is 958

aking into account identical letters, how many ways are there to arrange the word PARVAMONSTRA that both begin and end with consonants? (consonants are the non-vowel letters. In this word the consonants are R, P,V, M, N, S, and T)
There are 2,520 ways to arrange the word "PARVAMONSTRA" such that it begins and ends with consonants.
To arrive at this number, we need to consider the arrangement of the consonants at the beginning and end, as well as the arrangement of the remaining letters in the middle.
To determine the arrangement of the consonants at the beginning and end, we have 7 consonants to choose from.
Since the first and last letters must be consonants, we have 7 choices for the first letter and 6 choices for the last letter.
For the middle letters, we have 10 letters in total (including the remaining consonants and vowels). However, since some of these letters are repeated, we need to account for the repeated letters.
In "PARVAMONSTRA," the letters A and R are repeated twice. Therefore, we have 10!/(2!2!) ways to arrange the middle letters.
Multiplying the choices for the first and last letters (7 * 6) and the number of ways to arrange the middle letters (10!/(2!2!)), we get a total of 2,520 ways to arrange the word "PARVAMONSTRA" with consonants at both the beginning and end.
Therefore, there are 2,520 different ways to arrange the word "PARVAMONSTRA" such that it starts and ends with consonants, taking into account the repetition of the letters A and R.

A pair of gamma rays emitted from the same annihilation event collide with sensors, but their collisions occur 0.33 nanoseconds apart. What is the minimum distance the annihilation could have occurred from the center of the machine
The minimum distance the annihilation event could have occurred from the center of the machine is approximately 98.94 nanometers.
To determine the minimum distance the annihilation event could have occurred from the center of the machine, we can use the speed of light as a constant and the time difference between the collisions of the gamma rays.
The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).
Since the time difference between the collisions of the gamma rays is given as 0.33 nanoseconds, we need to convert this time to seconds. One nanosecond is equal to 1 × 10⁻⁹seconds.
0.33 nanoseconds is equal to 0.33 × 10⁻⁹ seconds.
Now, we can calculate the minimum distance using the equation:
Distance = Speed of light × Time
Distance = 299,792,458 m/s × 0.33 × 10⁻⁹ seconds
Distance ≈ 98.94 nanometers
