is a + b rational or irrational
Answer:
I think it would be rational
Answer and Step-by-step explanation:
It depends on the numbers that are inputted for a and b.
If the numbers that are inputted for both a and b are rational, then a + b would be rational.
If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.
If one of the variables is rational and the other is irrational, then a + b would be irrational.

Lines m and n are parallel solve for the following values of x. Tell which theorem you used.
Answer:
x=60°
Step-by-step explanation:
angle 135° and (2x+15)° are corresponding and thus are equal
Therefore (2x+15)°=135°
2x=135-15
2x=120°
X=60°
Each gallon of paint covers $200$ square feet. I have to paint one side of a wall that is $12$ meters tall and $80$ meters long. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?
The smallest whole number of gallons require to paint the wall is 52 gallons.
Given that, 1 gallon of paint = 200 ft², 1 foot = 0.3048 meters and dimension of wall is 12 meter by 80 meter.
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Converting the dimension to feet :
12/0.3084 = 39.370078 feet
80/0.3084 = 262.46719 feet
Hence, the area of the wall is
Area = Length × width
Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²
Let number of gallons required = x
Since, 1 gallon = 200 ft²
x gallons = 10093.516 ft²
Cross multiply :
200x = 10093.516
x = 10333.35374274082/200
x = 51.6667687137041 gallons
x = 52 gallons
Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint.

How many degrees is angle x?
Answer and Step-by-step explanation:
All triangles add up to 180, so to solve for x, add everything up and equal it to 180.
180 = 61 + 41 + x
180 = 102 + x
78 = x
78 is equal to x.

What is the triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.
The sum of all the angles in a triangle is add up to 180 degrees.
The sum of angle 1 is 61, and angle 2 is 41 degrees.
The value of x is;
[tex]\rm \angle x+61+41=180\\\\\angle x+102=180\\\\\angle x=180-102\\\\\angle x=78[/tex]

Mr. Powell rents a storage space that is 7 feet high, 5 feet long, and 4 feet wide.
How many containers, each one cubic foot in volume, can Mr. Powell fit into the storage space?
Answer:
To find how many 1 by 1 containers can fit in his storage space we must find the volume of the storage space in cubic feet. The formula for the volume of a rectangular prism aka the room is length x width x height. With this formula, all we need to do is plug in all the values given to the variables.
volume = length x width x height = 5 x 4 x 7 = 20 x 7 = 140
Final Answer: 140 one foot by one foot containers can fit in Mr. Powell's storage space

Nancy has a rectangular garden with length, I, width, w, and a perimeter of 28 feet The length of the rectangle is 2 less than 3 times the width. Choose the system of equations that can be solved to find land w
Answer:Perimeter =2l +2w
28=2(3x-2) + 2x
Width =4feet
Length =10feet
Step-by-step explanation:
Perimeter of rectangular garden =2(l+b)
Let the width be represented as X
And the length which is 3x-2
Such that the equation to solve for length and width be
Perimeter =2l +2w
28=2(3x-2) + 2x--- system of equation
Solving
28=2(3x-2) +2x
28=6x-4+2x
28=8x-4
28+4=8x
32=8x
X=32/8
X=4
Width =4
Length =3x-2=3x4-2=10

#5: Solve the
following
equation
60=5r-4r+14
(Show Work
Here)
Answer:
r = 46
Step-by-step explanation:
To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.
1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.
[tex]60 = 5r-4r + 14\\60 = r + 14[/tex]
2) Now, finally isolate r by subtracting both sides by 14.
[tex]60 = r + 14\\46 = r[/tex]
So, r = 46.

Gabriella's custom kitchen supplies sells handmade forks and spoons it costs the store 1.20 to buy the supplies to make a fork and 1.20 to buy the supplies to make a spoon the store sells forks for 4.60 and spoons for 4.00 last april her store spent 39.60 on materials for forks and spoons they sold the finishes products for a total of 140.40 how many forks and how many spoons did they make last
Answer:
14 forks and 19 spoons
Step-by-step explanation:
Let us represent:
Number of forks = x
Number of spoons = y
Gabriella's custom kitchen supplies sell handmade forks and spoons it costs the store 1.20 to buy the supplies to make a fork and 1.20 to buy the supplies to make a spoon. Last April her store spent 39.60 on materials for forks and spoons
Hence:
1.20x + 1.20y = 39.60.....Equation 1
The store sells forks for 4.60 and spoons for 4.00. They sold the finished products for a total of 140.40.
4.60x + 4.00y = 140.40......Equation 2
Hence:
1.2x + 1.2y = 39.6.....Equation 1
4.6x + 4y = 140.4....Equation 2
Multiply Equation 1 by 4 and Equation 2 by 1.2
4.8x + 4.8y = 158.4...Equation 3
5.52x + 4.8y = 168.48.....Equation 4
We subtract Equation 3 from 4
0.72x = 10.08
x = 10.08/0.72
x = 14 forks
Solving for y using Equation 1
x = 14
1.2x + 1.2y = 39.6.....Equation 1
1.2 × 14 + 1.2y = 39.6
16.8 + 1.2y = 39.6
1.2y = 39.6 - 16.8
1.2y = 22.8
y = 22.8/1.2
y = 19 spoons
Therefore, they made
14 forks and 19 spoons
Simplify.
