Answer:
A rational number is an integer that either doesn't have a decimal or has a decimal that either repeats or terminates (ends). Basically, if these square roots come out to be an integer, they're rational.
The first one comes out to be 42.6028168083, so obviously not rational.
The second one comes out to be 55, so it is rational.
Consider the provided numbers.
√1,815 and √3,025
The value of √1,815 = 48.60281680.....
The value of √3,025 = 55
Now consider the definition of rational and irrational number.
Rational number: A number is said to be rational, if it is in the form of p/q. Where p and q are integer and denominator is not equal to 0.
Irrational number: A number is irrational if it cannot be expressed be expressed by dividing two integers. The decimal expansion of Irrational numbers are neither terminate nor periodic.
The number √1,815 is an irrational number as the decimal expansion of numbers is neither terminate nor periodic.
The number √3,025 is a rational number as it is in the form of p/q.

Farmer John walks his pet pig around his barn every day. The barn is 25
meters by 12 meters. If we walks the pig around the barn three times, how
many meters did farmer John and his plg walk?
Answer:
900m
Step-by-step explanation:
A=wl
W=25
L=12
A=25 x 12
A= 300
300 meters x 3 laps = 900 meters walked
Farmer John and his pig walks 222 meters distance if he walks the pig around the barn three times.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
Give that,
The length of Barn = 25 meters.
And width of Barn = 12 meters.
The perimeter of barn = 2 (12 + 25) = 2 x 37 = 74 meters.
Since, farmer walks the pig around the barn 3 times,
So the total distance covered by farmer John and his pig
= 3 x perimeter of barn
= 3 x 74
= 222 meters.
Hence, farmer and his dong covers 222 meters distance.

How many minutes are there in 2.35 years?
Answer:
1235160
Step-by-step explanation:
Everyone knows that there are 24 hours in a day and 60 minutes in an hour. So you do 24 x 60 which is 1440. And then do 365 x 1440 ( because there is 365 days in a year) which is 525600 and then you multiply that by 2.35. Your final answer is 1235160.
DS=3x+10 and SE=6x-2. What is the value of DE?
Answer:
9x+8
Step-by-step explanation:
Given DS = 3x+10 and SE = 6x-2_ the value of DE is expressed as shown;
DE = DS+SE
Substitute the given functions into the formula to get DE
DE = (3x+10)+(6x-2)
Open the parentheses
DE = 3x+10+6x-2
Collect the like terms
DE = 3x+6x+10-2
DE = 9x+8
Hence the value of DE is 9x+8

one number is 2 less than a second number. twice the second number is 22 more than 5 times the first
Answer:
The first number is -6. The second number is -4.
Step-by-step explanation:
Let the second number be x.
"one number is 2 less than a second number"
Second number: x
First number: x - 2
"twice the second number is 22 more than 5 times the first"
2x = 5(x - 2) + 22
Distribute on the right side.
2x = 5x - 10 + 22
Subtract 5x from both sides. Combine like terms on the right side.
-3x = 12
Divide both sides by -3.
x = -4
x - 2 = -4 - 2 = -6
The first number is -6. The second number is -4.
What is x in this equation? -2x - 4 + 5x =8
10 + 2x – 4 = 2x + 1 + x ?
Answer:
x = 5
Step-by-step explanation:
10 + 2x - 4 = 2x + 1 + x
First, we can subtract 2x from both sides:
10 - 4 = 1 + x
We can simplify 10-4 to 6:
6 = 1 + x
Now, we can subtract 1 from both sides:
5 = x
x = 5
Answer:
x=5
Step-by-step explanation:
10+2x=4=2x+1+x (Then subtract 2x from both sides)
-2x. -2x
10-4=1+x (Simplify)
1+x=10-4 (Switch sides)
1+x=6 (Then subtract the numbers: 10-4=6)
1+x=6 (Subtract 1 from both sides)
-1 -1
x=5
When is a quadrilateral both a trapezoid and a parallelogram? Complete the explanation.
When there are (select: no pairs, one pair, two pairs) of parallel lines, which are lines with (select: the same slope, different slopes)
Answer:
TWO PARALLEL LINES AND LINES WITH EQUAL LENGTHS
Step-by-step explanation:
As we all know a quadrilateral is a polygon with four sides(edges and corners). Trapezoid is a four-sided shape with opposite sides parallel while parallelogram is also a for sided shape that has its opposite sides paralleled.
NOW, a quadrilateral is said to be both a trapezoid and a parallelogram when there are two opposite parallel lines, which are lines with equal lengths.

Answer:
7b, 8a
Step-by-step explanation:
using the equation y=m(x)+b, m(x) is the slope, and b is the y intercept. Oky so for 7, its a slope of negative 2, and it has a y-intercept of 5, and if you look at graph b a slope of -2 and would be a y-intercept of 5.
looking at equation a, its a Quadric function, f(x)=x^2, but it doesn't match the graph... strange because the graph for that equation would look like the image included. Hopefully this helps!
