Two numbers have square roots about 40 apart. What could they be?
The two numbers such that their square roots about 40 apart will be 2401 and 81.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Let's consider the number 8² = 64
Now, 64 - x = 40
x = 64 -40 = 24 and it is not a square of any number.
Take, 7² = 49
49 - x = 40
x = 9 it is a square of 3.
Thus, 7² - 3² = 40
So, 49² = 2401 and 9² = 81
Hence "The two numbers such that their square roots about 40 apart will be 2401 and 81".

Elliott is counting the change from a class fundraiser. He has half as many quarters as nickels, and he has 7 fewer dimes than nickels. The total value of coins is $5.90. He wrote the equation 0.10 (7 minus x) + 0.5 (x) + 0.25 (one-half x) = 5.90. Which statements identify Elliott’s errors? Check all that apply.
He should have written the expression for the number of dimes as x – 7.
He should have written the coin values as 5, 10, and 25 and not as 0.5, 0.10, and 0.25.
He should have written the coin value for the nickel as 0.05.
He should have translated the scenario as value of all dimes = value of all nickels and value of all quarters = value of all nickels.
He should have written the expression for number of nickels as 2x.
Answer: He should have translated the scenario as value of all dimes = value of all

In what ways is it useful to develop an algorithm for adding and subtracting rational numbers?
Answer:
To add or subtract these rational numbers, you first need to change your rational numbers so that they share a common denominator. Once you have a common denominator, you can then go ahead with the addition or subtraction of just the numerator part
Step-by-step explanation:
The algorithm is shown below
What is Algorithm?An algorithm in math is a procedure, a description of a set of steps that can be used to solve a mathematical computation.
For example, a step-by-step procedure used in long divisions is a common example of a mathematical algorithm.
To add or subtract these rational numbers,
First make sure that both the rational number must have same denominator. After that having common denominator proceed with subtraction or addition.The subtraction or addition only be performed with numerator not with denominator.Learn more about rational number here:

Solve for X
X=..........................
Answer:
(3x -5)°+ (2x- 15)°=180°[sum of co- Interrior angles of a triangle is 180°]
or, 3x- 5 + 2x - 15=180°
or,5x - 20 = 180°
or, 5x = 180°+20
or, x = 200÷ 5
•°•x = 40°
Answer:
X = 40
Step-by-step explanation:
3x + 2x -5 -15 = 180
5x + -20 = 180
then u add 20 on both sides
5x + 0 = 200
ya the 0 is not necessary but I was showing u add 20 on both sides lol
then u divide 5 on both sides to get the x by itself
x = 40

A negative integer and a positive integer
Step-by-step explanation:
You want to build this bookshelf. Given that a∥ b and m∠3=x and m∠2=x+30. Find the measure of ∠4, ∠5, and ∠6
m<4= ___ Degrees
m<5= ___ Degrees
m<6= ___ Degrees
Answer:
[tex]\huge\boxed{m \angle 4 = 105 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 5 = 75 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 6 = 105 \textdegree}[/tex]
Step-by-step explanation:
We can use basic angle relationships to find the measures of m∠4, m∠5, and m∠6.
We know that angles m∠3 and m∠2 are supplementary. This means their angle lengths add up to 180°. Since we know the expression for both, we can add them and solve for x.
[tex](x) + (x+30)=180[/tex] [tex]2x+30=180[/tex] [tex]2x=150[/tex] [tex]x = 75[/tex]So x = 75°, aka m∠3 is 75°. This means m∠2 is going to be [tex]75+30=105[/tex]°.
m∠4 is an opposite angle to m∠2. This means their angle lengths are the same. Therefore, m∠4 is 105°.
We also know that m∠3 and m∠5 are alternate interior angles, meaning their angle lengths are the same. Since m∠3 is 75°, m∠5 is also 75°.
We also know that m∠6 is a corresponding angle to m∠2. This means their angle lengths are the same. Since m∠2 is 105°, m∠6 is also 105°.

3. The points (15,21) and (25,35) form a proportional relationship.
a) Find the slope of the line through the points.
b) Which graph represents this relationship?
Answer:the letter is c because it the only one that is lined up and I got it right trust me
Step-by-step explanation:
The slope of the line passing through (15,21) and (25,35) is 7/5.
What is slope?The slope of a line is a measure of its steepness.
Given that, the points (15,21) and (25,35) form a proportional relationship.
Slope = (y2-y1)/(x2-x1)
= (35-21)/(25-15) = 14/10 = 7/5
The equation of a line passing through these two points are;
y - y1 = [(y2−y1)/(x2−x1)](x - x1)
y - 21 = 7/4(x - 25)
y = 7x/4 - 14
Hence, the slope of the line = 7/5

The dimensions of a rectangular dining room are 18 feet by 16 feet. If a scale factor of One-fourth is used to make a scale model of the dining room, what is the area of the dining room in the scale model?
18 square feet
36 square feet
48 square feet
72 square feet
Given -
The dimensions of a rectangular dining room are 18 feet by 16 feet. i.e, length (l) = 18 feet and breadth (b) = 16 feetScale factor of One-fourth is used to make a scale model of the dining room.To find -
the area of the dining room in the scale model (A)Solution -
As we know, the area of rectangle = length of the rectangle × breadth of the rectangle
To state the dimensions of the scale model we will multiply 1/4 with the already given dimensions of a rectangular dining room. Hence, dimensions of scale model is 18/4 by 16/4.
Now,
Area = length × breadth
Area = 18/4 × 16/4 square feet
Area = 18 square feet
Therefore, the area of the dining room in the scale model (A) is 18 square feet.
Answer:

How do you write 5y<3 without exponents?
Answer:
When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.

In complete sentences explain why you can sometimes add square roots with different radicands. Give an example where you can add square roots with different radicands and an example where you cannot add square roots with different radicands.
Answer:
Just as with "regular" numbers, square roots can be added together. But you might not be able to simplify the addition all the way down to one number. Just as "you can't add apples and oranges", so also you cannot combine "unlike" radical terms. In order to be able to combine radical terms together,
those terms have to have the same radical part.
