Which number produces an irrational number when added to 0.4
Answers
To find an irrational number when added to 0.4, you need to add an irrational number. One example is adding the square root of 2 to 0.4.
To find a number that produces an irrational number when added to 0.4, let's consider a rational number like 0.6.
Irrational numbers are infinite in nature and cannot be represented accurately as a finite decimal or fraction. They exist along with rational numbers, forming the set of real numbers on the number line.
0.4 + 0.6 = 1, which is rational.Rational + Irrational = Irrational, so to get an irrational number, you need to add an irrational number.One example of an irrational number you can add to 0.4 to get irrational is √2 - 0.4, where √2 is irrational.PLEASE HELP A flight across the US takes longer east to west then it does west to east. This is due to the plane having a headwind flying westward (thus slowing it down) and a tailwind flying eastward (thus pushing it along faster). Suppose you are flying from Philadelphia, PA to San Diego, CA. The distance between the cities is 2,400 miles and the plane's speed is 450 mi/hr. What is the speed of the wind?

where
[tex]d[/tex] is distance
[tex]v[/tex] is speed
[tex]t[/tex] is time
1. Let [tex]v_{w}[/tex] be the speed of the wind, [tex]t_{w}[/tex] be time of the westward trip, and [tex]t_{e}[/tex] the time of the eastward trip. We know from our problem that the distance between the cities is 2,400 miles, so [tex]d=2400[/tex]. We also know that the speed of the plane is 450 mi/hr, so [tex]v=450[/tex]. Now we can use our equation the relate the unknown quantities with the quantities that we know:
Going westward:
The plane is flying against the wind, so we need to subtract the speed of the wind form the speed of the plane:
[tex]d=vt[/tex]
[tex]2400=(450-v_{w})t_{w}[/tex]
Going eastward:
The plane is flying with the wind, so we need to add the speed of the wind to the speed of the plane:
[tex]d=vt[/tex]
[tex]2400=(450+v_{w})t_{e}[/tex]
We can conclude that you should complete the chart as follows:
Going westward -Distance: 2400 Rate:[tex]450-v_w[/tex] Time:[tex]t_w[/tex]
Going eastward -Distance: 2400 Rate:[tex]450+v_w[/tex] Time:[tex]t_e[/tex]
2. Notice that we already have to equations:
Going westward: [tex]2400=(450-v_{w})t_{w}[/tex] equation(1)
Going eastward: [tex]2400=(450+v_{w})t_{e}[/tex] equation (2)
Let [tex]t_{t}[/tex] be the time of the round trip. We know from our problem that the round trip takes 11 hours, so [tex]t_{t}=11[/tex], but we also know that the time round trip is the time of the westward trip plus the time of the eastward trip, so [tex]t_{t}=t_w+t_e [/tex]. Using this equation we can express [tex]t_w[/tex] in terms of [tex]t_e[/tex]:
[tex]t_{t}=t_w+t_e [/tex]
[tex]11=t_w+t_e[/tex] equation
[tex]t_w=11-t_e[/tex] equation (3)
Now, we can replace equation (3) in equation (1) to create a system of equations with two unknowns:
[tex]2400=(450-v_{w})t_{w}[/tex]
[tex]2400=(450-v_{w})(11-t_e)[/tex]
We can conclude that the system of equations that represent the situation if the round trip takes 11 hours is:
[tex]2400=(450-v_{w})(11-t_e)[/tex] equation (1)
[tex]2400=(450+v_{w})t_{e}[/tex] equation (2)
3. Lets solve our system of equations to find the speed of the wind:
[tex]2400=(450-v_{w})(11-t_e)[/tex] equation (1)
[tex]2400=(450+v_{w})t_{e}[/tex] equation (2)
Step 1. Solve for [tex]t_{e}[/tex] in equation (2)
[tex]2400=(450+v_{w})t_{e}[/tex]
[tex]t_{e}= \frac{2400}{450+v_{w}} [/tex] equation (3)
Step 2. Replace equation (3) in equation (1) and solve for [tex]v_w[/tex]:
[tex]2400=(450-v_{w})(11-t_e)[/tex]
[tex]2400=(450-v_{w})(11-\frac{2400}{450+v_{w}} )[/tex]
[tex]2400=(450-v_{w})( \frac{4950+11v_w-2400}{450+v_{w}} )[/tex]
[tex]2400=(450-v_{w})( \frac{255011v_w}{450+v_{w}} ) [/tex]
[tex]2400= \frac{1147500+4950v_w-2550v_w-11(v_w)^2}{450+v_{w}} [/tex]
[tex]2400(450+v_{w})=1147500+2400v_w-11(v_w)^2 [/tex]
[tex]1080000+2400v_w=1147500+2400v_w-11(v_w)^2[/tex]
[tex](11v_w)^2-67500=0[/tex]
[tex]11(v_w)^2=67500[/tex]
[tex](v_w)^2= \frac{67500}{11} [/tex]
[tex]v_w= \sqrt{\frac{67500}{11}} [/tex]
[tex]v_w=78[/tex]
We can conclude that the speed of the wind is 78 mi/hr.

Darrin lives in Washington, D.C., which has a sales tax of 6%. He just bought a video camera whose full price was $620, but after sending in a rebate form, he later received a check in the mail for $95. What was the total amount that Darrin ended up paying after receiving the rebate? A.$562.20 B.$556.50 C.$525.00 D.$657.20
Answers
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Cost of video camera = $620
Rate of sales tax = 6%
Amount of sales tax is given by
[tex]\dfrac{6}{100}\times 620\\\\=\$37.2[/tex]
Total amount after sales tax is given by
[tex]\$620+\$37.2\\\\=\$657.20[/tex]
Amount of rebate = $95
So, final amount that Darrin ended up paying after receiving the rebate is given by
[tex]\$657.20-\$95\\\\=\$562.20[/tex]
Hence, option 'A' is correct.

Samuel paid $720 for a new music system. The list price for the music system was $800. What was his rate of discount?
Answers
Samuel received a 10% discount on the music system, calculated by finding the difference between the list price ($800) and the sale price ($720), then dividing that by the list price and multiplying by 100.
Explanation:The question at hand is about calculating the rate of discount Samuel received on his new music system. Initially, the list price of the music system was $800, but Samuel paid $720 for it. To find the rate of discount, we first need to determine the discount amount which is the difference between the list price and the sale price.
List Price = $800Sale Price = $720Discount Amount = List Price - Sale Price = $800 - $720 = $80Next, to find the rate of discount, we use the formula:
Rate of Discount = (Discount Amount / List Price) × 100
Substituting the values we have:
Rate of Discount = ($80 / $800) × 100 = 10%
Therefore, Samuel received a 10% discount on the music system.

Which rule can be used to describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3?
Answers
"Which rule ..." suggests you have some rules to choose from to describe the growth. Since you refer to "each interval from x=-1 to x=3", we assume your rule is concerned with more than one interval. With no further clues as to what you may be looking for, we can compute the factor by which the function grows from x=-1 to x=3.
The growth factor over that interval is the ratio of final value to initial value:
.. (12^3)/(12^-1) = 12^(3 -(-1)) = 12^4 = 20,736
Answer:
The rule "multiply by 12" describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3.
Step-by-step explanation:
The given function is
[tex]y=12^x[/tex]
The initial value is 1 and the growth factor is 12.
It is an exponential function.
At x=-1
[tex]y=12^{-1}=\frac{1}{12}[/tex]
At x=0
[tex]y=12^{0}=12^{-1}\times 12=1[/tex]
At x=1
[tex]y=12^{1}=1 \times 12=12[/tex]
At x=2
[tex]y=12^{2}=12 \times 12=144[/tex]
At x=3
[tex]y=12^{3}=144 \times 12=1728[/tex]
Therefore the rule "multiply by 12" describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3.
Claire created a pie chart to show how she spent her time on Monday She spent 8 hours at school, 4 hours playing basketball, 2 hours doing homework, 8 hours sleeping, and 2 hours doing chores. Which statements describe how the pie chart will look? Check all that apply
Answers
The pie chart showing Claire's daily activities will have five sections representing school, basketball, homework, sleeping, and chores. Each section will portray the fraction of 24 hours that she spends on that activity. For example, School and Sleeping will both occupy 1/3 of the pie chart each.
Explanation:The subject in question is related to pie charts in Mathematics, specifically fractions and percentages. Claire has a total of 24 hours in the day and her activities are school for 8 hours, basketball for 4 hours, homework for 2 hours, sleep for 8 hours, and chores for 2 hours. In the pie chart, her spent time in a day can be shown as fractions of the total time, 24 hours.
For instance, Claire spent 8/24 or 1/3 of her time at school; the pie chart will show a section occupying 1/3 of the circle representing this. Similarly, she spent 4/24 or 1/6 of her time playing basketball, 2/24 or 1/12 of her time doing homework, 8/24 or 1/3 of her time sleeping, and 2/24 or 1/12 of her time doing chores. Each of these fractions will be a section on the pie chart. Hence, the chart will have five different sections, each representing a different activity.

Answers
Answer:
The theoretical probability of obtaining letter 'r' at the 14th spin is:
[tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
It is given that:
A spinner has 8 equal sectors with different letters for each sector.
The sectors are labeled b, y, g, p, o, v, m, and r.
Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.
We are asked to find the theoretical probability that we will get letter r at the 14th spin.
The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.
Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:
[tex]\dfrac{1}{8}[/tex]
( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)
