Suppose the cpi was 110 last year and is 121 this year. instructions: in part a, enter your answer as a whole number. in part b, round your answer to 1 decimal place. if you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers.
a. what is this year’s rate of inflation?
The rate of inflation from last year to this year is calculated by finding the 'change in CPI' which is then divided by the 'old CPI' and multiplied by 100 to convert it into percentage. The change in CPI is the new CPI minus the old CPI. By following the steps, we find that the rate of inflation is 10%.
Explanation:To calculate the rate of inflation, we first need to determine the 'change in CPI', which will then be divided by the 'old CPI'. The formula is:
(New CPI - Old CPI) / Old CPI x 100%
The 'change in CPI' is the new CPI (this year's CPI) minus the old CPI (last year's CPI). This will be:
121 (this year's CPI) - 110 (last year's CPI) = 11
Now, we'll divide 'change in CPI' by old CPI, which is:
11 (change in CPI) / 110 (old CPI) = 0.1
To convert the value into percentage, we should multiply it by 100:
0.1 x 100 = 10
So, this year's rate of inflation is 10%.

Divide and write the result in standard form: 3-i/1+5i
A. 1/13 +8/13i
B. -1/13+8/13i
C. 1/13-8/13i
D. -1/13-8/13i
Final answer:
The division of the complex numbers (3 - i) by (1 + 5i) results in the standard form -1/13 - 8/13i, by multiplying both the numerator and denominator by the conjugate of the denominator. The correct answer is option D.
Explanation:
To divide the complex number 3 - i by 1 + 5i, we should multiply numerator and denominator by the conjugate of the denominator to get rid of the imaginary part in the denominator:
Multiply both top and bottom by the conjugate of the denominator, which is 1 - 5i.(3 - i) * (1 - 5i) = 3 - 15i - i + 5i2
Since i2 = -1, it simplifies to:
3 - 16i - 5 = -2 - 16i
(1 + 5i) * (1 - 5i) = 1 - 5i + 5i - 25i2
Similarly, it simplifies to:
1 + 25 = 26
Divide the top result by the bottom result:(-2 - 16i) / 26 = -2/26 - 16i/26
Simplify the fractions:
-1/13 - 8/13i
The standard form of the result is -1/13 - 8/13i, which corresponds to option D.

The planet Mars has two moons – Phobos and Deimos. Phobos has a mass of 10.8 × 1015 kilograms, and Deimos has a mass of 2.0 × 1015 kilograms. How much greater is the mass of Phobos than the mass of Deimos?
Answer:
mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.
Step-by-step explanation:
The planet Mars has two moons Phobos and Deimos.
Mass of Phobos = 10.8 × 10¹⁵ Kilograms
Mass of Deimos = 2 × 10¹⁵ Kilograms
So the difference in the masses of the moons
= 10.8 × 10¹⁵ - 2 × 10¹⁵
= (10.8 - 2) × 10¹⁵
= 8.8 × 10¹⁵ Kilograms
Therefore, mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.
rearrange w=3(2a+b)-4 to make A the subject
To make A the subject in the equation w = 3(2a + b) - 4, the rearranged equation is: a = (w + 4 - 3b) / 6.
To rearrange the equation w = 3(2a + b) - 4 to make A the subject, we need to isolate A on one side of the equation. Here's how we can do it step by step:
Step 1: Distribute the 3 to the terms inside the parentheses:
w = 6a + 3b - 4.
Step 2: Move the 3b and -4 terms to the other side of the equation:
w + 4 = 6a + 3b.
Step 3: Rearrange the terms to isolate a:
6a = w + 4 - 3b.
Step 4: Divide both sides of the equation by 6 to solve for a:
a = (w + 4 - 3b) / 6.
Now, a is the subject of the equation. We have successfully rearranged the equation to express a in terms of w and b.
The probable question maybe:
rearrange w=3(2a+b)-4 to make A the subject in the equation.
The rearranged equation solving for [tex]\( a \)[/tex] is : [tex]\[ a = \frac{{w + 4}}{6} - \frac{{b}}{2} \][/tex]
This equation expresses [tex]\( a \)[/tex] as a function of [tex]\( w \)[/tex] and [tex]\( b \)[/tex], where [tex]\( w \)[/tex] is multiplied by [tex]\( \frac{1}{6} \) and \( b \)[/tex] is subtracted and then divided by [tex]\( 2 \)[/tex]. This equation can be used to calculate the value of [tex]\( a \)[/tex] given [tex]\( w \) and \( b \).[/tex]
To rearrange the equation [tex]\( w = 3(2a + b) - 4 \)[/tex] to solve for [tex]\( a \)[/tex], the first step is to isolate the term containing [tex]\( a \)[/tex] on one side of the equation.
1. Start by distributing the [tex]\( 3 \)[/tex] on the right side:
[tex]\[ w = 6a + 3b - 4 \][/tex]
2. Next, move the constants to the other side of the equation by adding [tex]\( 4 \)[/tex] to both sides:
[tex]\[ w + 4 = 6a + 3b \][/tex]
3. Now, to isolate [tex]\( a \)[/tex], divide both sides by [tex]\( 6 \):[/tex]
[tex]\[ \frac{{w + 4}}{6} = a + \frac{{3b}}{6} \][/tex]
4. Simplify:
[tex]\[ \frac{{w + 4}}{6} = a + \frac{{b}}{2} \][/tex]
5. To solve for [tex]\( a \)[/tex], subtract [tex]\( \frac{{b}}{2} \)[/tex] from both sides:
[tex]\[ \frac{{w + 4}}{6} - \frac{{b}}{2} = a \][/tex]
So, the rearranged equation solving for [tex]\( a \)[/tex] is:
[tex]\[ a = \frac{{w + 4}}{6} - \frac{{b}}{2} \][/tex]

Final answer:
The Long family spent $38.62 for school supplies and $215.78 for new school clothes. To find the total amount spent, add the cost of school supplies and new school clothes. To calculate the sales tax, multiply the total amount spent by the sales tax rate.
Explanation:
To find the total amount spent, we need to add the cost of school supplies and new school clothes. The Long family spent $38.62 on school supplies and $215.78 on new school clothes, so the total amount spent is $38.62 + $215.78 = $254.40. Now, to calculate the sales tax, we need to find the percentage of the total amount spent. Let's assume the sales tax rate is 8%. To find the sales tax amount, we multiply the total amount spent by the sales tax rate as a decimal: $254.40 x 0.08 = $20.35.

The formula d = rt gives the distance traveled in time t at rate r. A bicyclist rides for 1.5 hours and travels 25 miles.
What was her average speed?
Answer:
16 2/3
Step-by-step explanation:
The bicyclist's average speed was 16.67 miles per hour
The student asks about the average speed of a bicyclist who traveled for 1.5 hours and covered 25 miles. The average speed can be found using the formula v = d/t, which suggests speed (v) equals distance (d) divided by time (t). To solve for the bicyclist's average speed, we'll insert the given values into the formula.
Here's the step-by-step calculation:
Identify the given variables: d = 25 miles and t = 1.5 hours.
Substitute the values into the formula: v = 25 miles / 1.5 hours.
Calculate the quotient to find the average speed: v = 16.67 miles per hour (rounded to two decimal places).
Therefore, to find the bicyclist's average speed, divide the distance traveled, 25 miles, by the time spent, 1.5 hours, which yields an average speed of 16.67 miles per hour.
