The peak wavelength that Earth emits as a blackbody is approximately equal to 9.657 × 10⁻⁶ m.
How to determine the peak wavelength that Earth emits as a blackbody radiator
The Wien's displacement law is a consequence of Planck's radiation law, that states the brightness of a radiative body is a function of wavelength at a given temperature. Wien's displacement law states that peak wavelength is inversely proportional to the temperature (T), in Kelvin. The Wien's displacement law is represented by the following formula:
λ' = b / T
Where:
λ' - Peak wavelength, in meter-Kelvin.T - Temperature, in Kelvin.λ' - Peak wavelength, in meters.If we know that b ≈ 2.897 × 10⁻³ m · K and T ≈ 300 K, then the peak wavelength of the Earth is:
λ' = (2.897 × 10⁻³ m · K) / (300 K)
λ' ≈ 9.657 × 10⁻⁶ m

The length of rectangular room is 9.5 meter.
The width of rectangular room is 5 meter.
What is Perimeter of rectangular?
The perimeter of a rectangle is two time the sum of length and width of rectangle.
Given that;
The perimeter of rectangular room = 29 meter
The length of rectangular room is 1.9 times as long as it is wide.
Now, Let the width of rectangular room = x
Then Length of rectangular room = 1.9x
Since, Perimeter of rectangular room = 2 ( length + width)
⇒ 29 = 2 (1.9x + x)
⇒ 29 = 2 * 2.9x
⇒ x = 5
Hence, The length of rectangular room = 1.9x
= 1.9 * 5
= 9.5 meter
The width of rectangular room is = x
= 5 meter.
So, The length of rectangular room is 9.5 meter.
The width of rectangular room is 5 meter.

In a warehouse, there are 2 robots that work together. They move in the same direction concurrently, so if one moves North, they both North. The robots will follow any instructions they’re given and will collect any objects they find along the way. They only take instructions by the points of the compass and can only move in 4 directions (N, E, S, W).
For example, if the 2 robots are given the directions: “N, E, S”, then Robot A will collect a ball and Robot B will collect a hat.
Write the directions the robots would need to follow to collect the following objects, remembering that both robots get the same directions, and assuming that for each question they start off in the same (pictured above) positions:
1. Robot A: ball Robot B: ball
2. Robot A: hat, ball Robot B: box, hat
3. Robot A: ball, ball Robot B: hat, ball
1. For collecting balls by both Robot A and B the direction will be N->E->E
2. For collecting hat and ball by Robot A and box and hat by Robot B, the direction will be N->N->S->E->E
3. For collecting both the balls by Robot A and a hat and ball by Robot B, the direction will be E->E->N
The direction that both Robot A and Robot B can take are N, E, S and W
For Part 1:
Robot A and Robot B need to collect the ball which is in the 2nd row 5th column for Robot A and 4th row 3rd column for Robot B, therefore the direction will be:
=N->E->E
For Part 2:
Robot A needs to collect a hat and ball which are in the 1st-row third column and 2nd row 5th column respectively. Robot B needs to collect a box and a hat which are in the 3rd row 1st column and 4th row 3rd column respectively. Therefore, the direction will be:
= N->N->S->E->E
For Part 3:
Robot A needs to collect both the balls which are in the 3rd-row 4th column and 2nd row 5th column respectively. Robot B needs to collect a hat and a ball which are in the 5th row and 2nd column & 4th row 3rd column respectively. Therefore, the directions will be:

After that she has to pay 5 % sales tax:
$186.375 x 1.05 = $195.70
Answer:
The total cost of the items is $195.70.
Dana has driven her car 95,598 miles. She estimates she can
drive the car another 5000 miles before the mileage reaches
100,000 miles. Use the rules for estimating differences to
explain if Dana is correct.
Answer: Dana estimation is incorrect because difference = 598 miles
Step-by-step explanation:
Given data,
Dana has driven her car 95,598 miles.
She estimates she can
drive the car another 5000 miles.
she can,
drive the car another 5000 miles before the mileage reaches
100,000 miles.
Estimated Mileage of the car is equal to 100,000 miles.
That is,
Estimated Mileage of the car is = 100,000 miles.
So,
We can write,
Total distance Dana has to travel = already driven + additional miles to cover
Total distance Dana has to travel = 95,598 + 5,000 miles
Total distance Dana has to travel = 1,00,598 miles.
As per mileage of car is 100,000 miles.
So, Dana has to travel = 1,00,598 miles.
So, Dana estimation is incorrect because difference is = 100,598 - 100,000
Therefore,
Dana estimation is incorrect because difference = 598 miles

The shelf life of a battery produced by one major company is known to be normally distributed with a mean life of 3.5 years and a standard deviation of 0.75 years. What percent of batteries last between 1.25 and 5.75 years?
The percentage of batteries that last between 1.25 and 5.75 years will be 99.73%.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
One significant manufacturer's batteries are known to have a shelf life that is regularly distributed, with an average life of 3.5 years and a standard deviation of 0.75 years.
The value of the z-score will be
z = (1.25 - 3.5) / 0.75, (5.75 - 3.5) / 0.75
z = -3, 3
The percentage of batteries that last between 1.25 and 5.75 years will be
P(1.25 < x < 5.75) = P(- 3 < z < 3) x 100
P(1.25 < x < 5.75) = 0.9973 x 100
P(1.25 < x < 5.75) = 99.73%
The percentage of batteries that last between 1.25 and 5.75 years will be 99.73%.

Monica sold 3 pairs of her old Slick Sprinter sneakers at the Re-Laced secondhand store. Before she left, Monica spent $13 of her earnings on a used pair of boots. She had $8 remaining. How much did Monica receive for each pair of sneakers?
Monica received $ 7 amount of money for each pair of sneakers she sold.
We are given that:
Remaining amount with Monica = $ 8
She spent on earing = $ 13
The total amount she had = $ 13 + $ 8
The total amount she had = $ 21
Now, she sold 3 pairs of sneakers and gained $ 21
So, the price of each snicker will be calculated by using division.
So, we get that:
Monica receive for each pair of sneakers = $ 21 / 3 = $ 7
Therefore, Monica received $ 7 amount of money for each pair of sneakers she sold.

Aleka: f(x) = 2500(1.025)x
Helene: g(x) = 1500(1.025)x + 200x
Which function represents the difference, h(x) = f(x) – g(x), between the value of Aleka’s and Helene’s total savings after x years?
h(x) = –1000(1.025)x + 200x
h(x) = 1000(1.025)x + 200x
h(x) = 1000(1.025)x – 200x
h(x) = 4000(1.025)x + 200x
The function that represents the difference, h(x) = f(x) – g(x), between the value of Aleka’s and Helene’s total savings after x years is C. h(x) = 1000(1.025)x – 200x.
How to illustrate the function?It should be noted that Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account.
The function for Aleka will be:
= 2500 (1.025)^x

U= ({a,b,c,d,e,f.g.h}
A = {f,g,h}
B={a,g,h}
C={a,b,c,d,e)
Answer:
{a}
Step-by-step explanation:
You want the set A'∩(B∪C') given the definitions of each of the sets U, A, B, C.
Inverse setsThe inverse of a set is the set of elements of the universal set that are NOT in the given set.
A' = {a, b, c, d, e, f, g, h} - {f, g, h} = {a, b, c, d, e}
C' = {a, b, c, d, e, f, g, h} - {a, b, c, d, e} = {f, g, h}
UnionThe union of two sets is the list of elements in either of the two sets.
B∪C' = {a, g, h} +{f, g, h} = {a, f, g, h}
IntersectionThe intersection of two sets is the list of elements common to both:
A'∩(B∪C') = {a, b, c, d, e} ∩ {a, f, g, h} = {a}
