The area of a square is 400 square units. Select all the statements that would be true if the length of each side of the square increased by one unit.
A-The area of the square would be a rational number.
B-The area of the square would be an irrational number
C-Each side length would be a perfect square.
D-The area of the square would be a perfect square.d
E -The area of the square would be a nonterminating, nonrepeating decimal.
PLEASE ANSWER ASAP!!!! WILL GIVE BRAINLIEST!
Answer:
A and D
Step-by-step explanation:
Given that the area of a square = 400 units² = s²
Where s is one side length of the square.
It means that the side length (s) = √400 = 20
If the length of each side length increase by 1 units, new side length = 21 units
Area of new square = 21² = 441
The following statements would be true if the side length was increased by 1 units:
A. "The area of the square would be a rational number"
441 is a rational number, because a rational number is a quotient of two integers.
441 and 1 are two integers. Their quotient = 441. I.e. 441 ÷ 1 = 441
D. "The area of the square would be a perfect square".
A number is considered a perfect square if it can be expressed as a product of two equal integers.
441 can be expressed as 21*21

Factor 3xy+21x+9 completely
- 3x(y+7x+6)
- 3(xy+7x+3)
- Prime (Not Factorable)
- xy+2x+3
Answer:
Hence the second option is the correct answerStep-by-step explanation:
In this problem we are required to factor out the given terms as stated in the expression, what is obtainable is that we look for terms(greatest terms) that are common to all the terms in the expression and factor it out.
here is a way to do it
given the following expression
[tex]3xy+21x+9[/tex]
From the expression above we can see that 3 is common to all the terms of the expression so that we have
[tex]3(xy+7x+3)[/tex]
hence the second option is the correct answer

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?
Answer : The correct option is, (B) 1500 cubic yards.
Step-by-step explanation :
Formula used to calculate the volume of square pyramid is:
[tex]V=\frac{a^2\times h}{3}[/tex]
where,
V = volume of pyramid
a = base edge of pyramid
h = height of pyramid
Given:
Base edge of pyramid = 15 yards
Height of pyramid = 20 yards
Now putting all the given values in the above formula, we get:
[tex]V=\frac{a^2\times h}{3}[/tex]
[tex]V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}[/tex]
[tex]V=1500\text{ yards}^3[/tex]
Therefore, the volume of pyramid is 1500 cubic yards.

For the function f(x)=|4x−2|+10, evaluate f(−3).
Answer:
[tex]f(-3)=24[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=|4x-2|+10[/tex]
To find f(-3), substitute -3 for x:
[tex]f(-3)=|4(-3)-2|+10[/tex]
Multiply within the absolute value:
[tex]f(-3)=|-12-2|+10[/tex]
Subtract:
[tex]f(-3)=|-14|+10[/tex]
The absolute value of -14 is 14. Thus:
[tex]f(-3)=14+10[/tex]
Add:
[tex]f(-3)=24[/tex]

This is in the slope-intercept form, where:
[tex]y=mx+b[/tex]
Here, m is the slope and b is the y-intercept.
From the original equation, m is 3 and b is -2.
In other words, our slope is 3.
So, the slope of the equation is 3.

Use known logical equivalences to prove that a → (b → c) is logically equivalent to (a ^ b) → c.
Answer:-
a ∨ ( b ∨ c ) ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c
Step-by-step explanation:
Explanation :-
we know that b→ c ⇔ b∨c
Replacing b→ c ⇔ b ∨ c , we get
a → b ∨ c ,
By the same rule b→ c ⇔ b∨c
⇒ a ∨ ( b ∨ c )
Now
a ∨ ( b ∨ c ) ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c

1. 3x = 2x + 2
2. 3x + 5 = 4x + 1
3. 6x + 3 = 3x + 12
Step-by-step explanation:
3x = 2x + 23x - 2x = 2
x = 2
2. 3x + 5 = 4x + 1
4x - 3x = 5 - 1
x = 4

6x - 3x = 12 - 3
3x = 9
x = 3
Margaret drove to a business appointment at 90 mph. Her average speed on the return trip was 80 mph. The return trip took 1/4
hr longer because of heavy traffic. How far did she travel to the appointment?
Distance = speed x time
Let the time to the appointment = x
The time home would be x + 1/4 hour
set up an equation you have 90x = 80(x + 1/4)
Simplify:
90x = 80x + 20
Subtract 80x from both sides:
10x = 20
Divide both sides by 10:
x = 2 hours
Distance = 90 x 2 = 180 miles

The value after simplifying the expression 3² + 8 ÷ 2 - (4 + 3) is 6 by using PEMDAS rule.
To simplify the expression 3² + 8 ÷ 2 - (4 + 3), follow the order of operations (PEMDAS/BODMAS):
P - Parentheses first
E - Exponents (i.e., powers and square roots, etc.)
MD - Multiplication and Division (left to right)
AS - Addition and Subtraction (left to right)
Start with the exponent:
3² = 3 × 3 = 9.
Next, perform the division:
8 ÷ 2 = 4.
Now, deal with the parentheses:
(4 + 3) = 7.
Finally, perform the addition and subtraction from left to right:
9 + 4 - 7
= 6.
So, the simplified expression is 6.

As of mid-2016, the world's population was about 7.4 billion people. The population of Country A was 226 million. In mid-2016, what percent of the world's population was the Country A population? Round your answer as a percentage to one decimal place.
Answer:
The percentage of country A population to the world population
= 3.05%
Step-by-step explanation:
Country A population as of 2016
= 226 million
= 226000000
The world population as of 2016
= 7.4 billion
= 7400000000
The percentage of country A population to the world population
= Country A population /The world population
The percentage of country A population to the world population
= 226000000/7400000000
The percentage of country A population to the world population
= 0.03054
Now multiplying by 100
= 3.05%
The percentage of country A population to the world population is 3.05%
Given that,
As of mid-2016, the world's population was about 7.4 billion people. The population of Country A was 226 million.Based on the above information, the calculation is as follows:
[tex]= 226000000\div 7400000000[/tex]

Why is the square root of a non perfect square always irrational number ?
Answer:
The square root of any prime number must be an irrational number. For example, because of this proof we can quickly determine that √3, √5, √7, or √11 are irrational numbers...
Answer:
Yes, unless X is a perfect square, sqrt(X) is irrational
Step-by-step explanation:
The proof where X= 2 is an example of the general proof: Supposesqrt(X) is rational, then there exists integers p and q such that (p/q)^2 = 2, we can cancel any common factors out of p and q so these are the simplest integers which satisfy the equation.
