Step-by-step explanation:
The rational number can be written in the form of fraction that can be simplified into a integer.The irrational number cannot be written in the form of fraction.-4/5 is a rational number.
Reason: It is in the fraction form with -4 in the numerator and 5 in the denominator. .
√2 is irrational.
Reason: since it cannot be written as a fraction.
2.5 is rational number.
Reason: It can be written in the form of fraction such as 5/2.
0.4 is represented with a bar above the 4 which means that 4 gets repeated. It is a rational number
Reason: because it an integer.
√16 is rational.
Reason: It can be simplified as +4 or -4 which are integers.
Add 3 to x subtract the result from 1 then double what you have
If you add 3 to x you have [tex]3+x[/tex]
Subtract this from 1: [tex]1-(3+x)=1-3-x=-2-x[/tex]
Double this: [tex]2(-2-x)=-4-2x[/tex]
The required answer is 4 + 2x.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
The given expression is,
Add 3 to x subtract the result from 1 then double
Convert it to the numerical expression,
Add 3 to x = 3 + x
subtract the result from 1 = 3 + x - 1
⇒ subtract the result from 1 = 2 + x
Now double of result = 2(2 + x)
⇒ double of result = 4 + 2x
this is the required solution.
Thus, the required answer is 4 + 2x.

Deion Sanders can run the 40 yard dash in 4.19 seconds. At this rate, how long would it take him to run a mile?
**hint** There are 1760 yards in a mile.
Approximately 3:07 minutes Approximately 184.36 minutes Approximately 420 seconds Approximately 7 minutes
Answer:
184.36
Step-by-step explanation:
If you times 40×45=1760 so you have to times 4.19×44= The answer/ 184.36
Deion Sanders would approximately take 3 minutes and 7 seconds to run a mile at his 40 yard dash pace of 4.19 seconds, calculating his speed and using the number of yards in a mile to find the total time needed.
To calculate the time it would take Deion Sanders to run a mile at his 40 yard dash pace, we first determine his speed over that distance. We know he runs 40 yards in 4.19 seconds, so we can calculate his speed as follows:
Speed = distance / time
Speed = 40 yards / 4.19 seconds
Speed = 9.55 yards/second (approximately)
Since there are 1760 yards in a mile, to find out how long it will take to run a mile, we divide the total yards in a mile by the speed:
Time to run a mile = distance / speed
Time to run a mile = 1760 yards / 9.55 yards/second
Time to run a mile = 184.293 seconds (approximately)
Converting seconds to minutes yields approximately:
184.293 seconds = 3.07155 minutes (184.293 seconds / 60 seconds per minute)
This result shows that at Deion Sanders' 40 yard dash speed, it would take him approximately 3 minutes and 7 seconds to run a mile.

1. Mrs. Brown had $16 dollars in her
wallet. After shopping at the store, she
now has $8. How much money did
Mrs. Brown spend at the store?
Final answer:
Mrs. Brown spent $8 at the store, which is found by subtracting her remaining amount of $8 from her initial amount of $16.
Explanation:
The amount of money Mrs. Brown spent at the store can be calculated by subtracting the amount she had after shopping from the amount she had before going to the store. Mrs. Brown had $16 before shopping and was left with $8 after shopping. Therefore, to calculate how much money she spent, we would perform the following subtraction:
$16 (before shopping) - $8 (after shopping) = $8 (spent)
Hence, Mrs. Brown spent $8 at the store.
Savannah drove 716 miles on Monday. She drove another 572 miles one Tuesday. About how many more miles did she drive on Monday than Tuesday?
Final answer:
Savannah drove 144 more miles on Monday than she did on Tuesday, calculated by subtracting Tuesday's mileage from Monday's.
Explanation:
The student is asking how many more miles Savannah drove on Monday than Tuesday. To calculate this, we simply subtract the number of miles driven on Tuesday from the number of miles driven on Monday.
Miles driven on Monday: 716 miles
Miles driven on Tuesday: 572 miles
To find the difference in miles, we use the following equation:
716 miles (Monday) - 572 miles (Tuesday) = 144 miles
Therefore, Savannah drove 144 more miles on Monday than on Tuesday.

How do u find the density of a sphere
Answer:
Step-by-step explanation:
The formula to find density of a sphere is mass/volume.
Density in simple words means the relation between weight and size of a substance. It is basically related to the compactness of a substance.It is a very useful characteristic and every material has density.
To calculate density, we must calculate the mass and volume of the substance.
p=m/v
where p= density, m= mass of substance, v= volume of substance
Formula to calculate the volume of a sphere = 4/3 [tex]\pi r^{3} \\[/tex]
Therefore, density p =[tex]m/4/3\pi r^{3}[/tex]
p = 3m/4 [tex]\pi r^{3} \\[/tex]

Between the time Iko woke up and lunchtime, the temperature rose by 11 degrees. Then by the time he went to bed, the temperature dropped by 14 degrees.
Write an addition expression for the temperature relative to when Iko woke up.
Answer:
[tex]T_t=x\textdegree-3\textdegree[/tex]
Step-by-step explanation:
let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let [tex]T_t[/tex] be temperature at time t The temperature relative to time of waking up can be expressed as:
[tex]T_t=x\textdegree \pm \bigtriangleup T\textdegree\\\\T_t=x\textdegree + 11\textdegree -14\textdegree\\\\T_t=x\textdegree-3\textdegree[/tex]
Hence, temperature relative to time of waking up is expressed as

Answer:
width = 12.1
equation : P = 4w + 4.6
Answer:
The width of the rectangle is 12.1 meters
Step-by-step explanation:
Step 1: Find the width
2w + 2(w + 2.3) = 53
2w + 2w + 4.6 = 53
Step 2: Combine like terms
2w + 2w + 4.6 = 53
4w + 4.6 = 53
Step 3: Subtract 4.6 from both sides
4w + 4.6 - 4.6 = 53 - 4.6
4w = 48.4
Step 4: Divide both sides by 4
4w / 4 = 48.4 / 4
w = 12.1
Answer: The width of the rectangle is 12.1 meters

A rectangular park is 6x + 2 ft long and
3x + 7 ft wide. In the middle of the park is
a square turtle pond that is 8 ft wide. What
expression represents the area of the park not
occupied by the turtle pond? SEE EXAMPLE 6
The area of the park not occupied by the turtle pond= [tex]18 x^{2} + 48x -50 ft^2[/tex]
The length of the rectangular park given here is = [tex]6x + 2[/tex]
The breadth of the rectangular park given here is = [tex]3x + 7[/tex]
To calculate the area of the park (rectangle), firstly you are required to do = Length * breadth
So as per the values given in the question, you need to do = [tex](6x+2)(3x+7)[/tex]
After multiplying the above-given values, you will get
= [tex]18 x^2 + 42x + 6x+14 -64[/tex]
After simplifying the above value, you will get the final value or the area of the park not occupied by the turtle pond = [tex]18 x^2 + 48x -50 ft^2[/tex]

https://brainly.com/question/8663941
To calculate the area of the park not occupied by the pond, first compute the total area of the park as (6x + 2)(3x + 7). Then subtract the area of the square pond, 64 sq. ft, to get the final expression for the unoccupied park area: (6x + 2)(3x + 7) - 64.
Explanation:The subject of this question is Algebra, specifically forming an expression for the area of a rectangle and subtracting the area of a square. First, calculate the total area of the rectangular park. The area of a rectangle is given by the product of its length and width. So, the total area of the park is (6x + 2)(3x + 7).
Second, find the area of the turtle pond. Since it's a square with a side length of 8ft, its area is 8*8 = 64 sq. ft.
Finally, to find the area of the park that is not occupied by the turtle pond, subtract the area of the pond from the total park area. So, the final expression is (6x + 2)(3x + 7) - 64.
