Stephanie is painting her room wich is 14' long by 9' wide and each wall is 10' tall. How many square feet of paint will she use? help.
Answer:
460 sq ft
Step-by-step explanation:
Assuming the room is a perfect rectangle and not accounting for doors and windows:
14 ft x 10 ft = 140 sq ft X 2 = 280 sq ft
9 ft x 10 ft = 90 sq ft x 2 = 180 sq ft
280 sq ft + 180 sq ft = 460 sq ft

Answer:
D: [-4, 2]; R: [-2, 4]D: (-∞, 5]; R: [0, 0]D: [0, 5); R: [0, 7)D: (-∞, ∞); R: [0, ∞)Step-by-step explanation:
The domain is the horizontal extent. The range is the vertical extent. An arrow on the end of the graph means it extends to infinity in the same direction. An open circle indicates a point that is not included in the graph. A square bracket in interval notation means the point is included in the interval; a round bracket (parenthesis) means the point is not included. By convention, infinity is indicated with a round bracket, because it is not a specific number.
1. D: [-4, 2]; R: [-2, 4]
2. D: (-∞, 5]; R: [0, 0]
3. D: [0, 5); R: [0, 7)
4. D: (-∞, ∞); R: [0, ∞)

1) Andy buys k packets of crisps. Laura buys 2 more packets of crisps than Andy.
a. Write an expression for the total number of packets of crisps.
Answer:
2k + 2
Step-by-step explanation:
It's said that Andy buys k packets of crisps, meaning this is an unknown variable. Since Laura buys two MORE bags of crisps than Andy, her total number of chips will be k + 2. To find the TOTAL number of crisps between the two of them, you would have to add Andy's crisps, k, to Laura's crisps, k + 2. This will give you k + k + 2, which is just 2k +2.

Question
Joanna wants to tile a square floor that measures 8 feet on one side. If each tile is a 6-inch square, how
many tiles will she need for the floor?
O 64 tiles
O 192 tiles
O 256 tiles
O 324 tiles
The number of tiles needed to cover the floor is 256 tiles.
The given parameter:
the length of a side of the floor = 8 feet
the length of a side of the tile, = 6-inches
To find:
how many tiles she will need for the floorConvert the unit of the floor to inches
1 ft = 12 inches
8 ft = (8 x 12) = 96 inches
The area of the floor = 96 in x 96 in
The area of the floor = 9216 in²
The area of a tile = 6 in x 6 in
The area of a tile = 36 in²
The number of tiles needed to cover the floor:
[tex]number \ of \ tiles = \frac{Area \ of \ floor}{Area \ of \ a\ tile} = \frac{9216}{36} = 256 \ tiles[/tex]
Thus, the number of tiles needed to cover the floor is 256 tiles.

The distance from the earth to the moon is two hundred thirty eight thousand, nine hundred miles. Write the distance in standard form and expanded form.
Answer:
Standard: 238,900
Expanded: 200,000 + 30,000 + 8,000 + 900
Step-by-step explanation:
The distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the distance from the earth to the moon is two hundred thirty-eight thousand, nine hundred miles.
The number in standard form will be written as below:-
Standard form = 238,900
The number in the expanded form will be written as below:-
Expanded form = 200,000 + 30,000 + 8,000 + 900.
Therefore, the distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.

plz help.............. radius is 10 inch
Answer:
314 in²
Step-by-step explanation:
The formula for the area of a circle is pi*r² or pi (3.14...)* radius²(squared).
If you plug in the radius given into the equation, you get 3.14*10² you can then solve this using systems of equations.
3.14*10²
10² = 10*10
3.14*(10*10)
10*10= 100
