Robert is preparing a poster board project he wants tk make eecor patern eith 10 squares to fill part of the poster the area of the poster board is 720 square inches to find how much soace robert will have left for his project if he uses 7-inches evaluate 720-10s2 when s=7
To find the area of one square, we can square the length of one side (squared), which is (7 squared) = 49 square inches.
Since Robert wants to make a pattern with 10 squares, the total area covered by the squares would be 10 times the area of one square = (10 * 49) = 490 square inches.
To find the space Robert will have left for his project, we can subtract the area covered by the squares from the total area of the poster board: (720 - 490) = 230 square inches.
Therefore, Robert will have 230 square inches left for his project.
Mr.rodriguez has a veggie garden that boarder blme he want put fence around it it cosf 7$ per yard for the materials evaluate 7(l+2w) where l=length w=width to find the cosf for a gwrden that has a length of 5 ywrd wnd width of 2 yard
To find the cost of the materials for the fence, we can substitute the given values of length (l) and width (w) into the expression 7(l+2w).
Using l = 5 yards and w = 2 yards, we have:
Cost = 7(5+2*2)
= 7(5+4)
= 7(9)
= 63 dollars
Therefore, the cost for a garden with a length of 5 yards and width of 2 yards would be 63 dollars.
Simplifg 8a-2a
To simplify the expression 8a - 2a, we can combine like terms.
8a - 2a can be rewritten as (8 - 2)a.
Simplifying the coefficient, we have (8 - 2)a = 6a.
Therefore, 8a - 2a simplifies to 6a.
To find out how much space Robert will have left for his project, we need to subtract the area of the squares from the total area of the poster board.
Given:
Total area of the poster board = 720 square inches
Number of squares = 10
Length of one side of a square = s = 7 inches
Area of one square = s^2 = 7^2 = 49 square inches
Total area of the squares = Number of squares × Area of one square
= 10 × 49 = 490 square inches
Now, we can calculate the remaining space for Robert's project by subtracting the area of the squares from the total area of the poster board:
Remaining space = Total area of the poster board - Total area of the squares
= 720 - 490
= 230 square inches
Therefore, Robert will have 230 square inches of space left for his project.
To find out how much space Robert will have left for his project, we first need to calculate the area of the 10 squares.
The formula for finding the area of a square is A = s^2, where A represents the area and s represents the length of one side of the square.
Given that s = 7 inches, the area of one square is A = 7^2 = 49 square inches.
Since Robert wants to make 10 squares, we multiply the area of one square by 10:
Total area of the 10 squares = 49 * 10 = 490 square inches.
Now, to find out how much space Robert will have left for his project, we subtract the total area of the 10 squares from the area of the poster board:
Space left for the project = Area of the poster board - Total area of the 10 squares
= 720 square inches - 490 square inches
= 230 square inches.
Therefore, Robert will have 230 square inches of space left for his project.
