A wall in Marcus's bedroom is 8 2/5 feet high and 16 2/3 feet long. If he paints 1/2 of the wall blue, how many square feet will be blue?
Answers
8 2/5 feet high * 16 2/3 feet long = 8 2/5 * 16 2/3 = 42/5 * 50/3 = 140 square feet
1/2 * 140 = 140/2 = 70 square feet
The correct result would be 70 square feet.
The area that will be painted blue is 69.97 square feet.
How to find the area that will be painted blue?
Remember that for a rectangle of length L and width W, the surface area is given by:
In this case we have:
- L = (8 + 2/5)ft
- W = (16 + 2/3) ft.
Replacing that in the area equation:
And we know that half the wall is painted, so the area that will be blue is:

The distance of salmon from the surface of the water is 8 feet.
What are mathematical operations?
Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
The distance of school of salmon for the surface of the river = 5 feet.
Since, to escape a hungry bear, the school of salmon went down to 3 feet.
The position of the salmon to the surface = 5 + 3 = 8 feet.
The required distance of school of salmon from the surface of water is 8 feet.

Answer:
8 Feet below the surface
Step-by-step explanation:
If the salmon were initially 5 feet below the surface, and then travelled down an additional 3 feet from the initial 5, then the new position would be 8 feet down relative to the surface.
You can write this as -5 + -3 = -8, assuming that 0 represents surface level.

Let us assume the total number of bowls of cereal that Nathan has eaten in a year = x
With each bowl of cereal, Nathan has 1/18 gallon of Milk.
In total the number of gallons of mulk in a year = 8 gallons,
Therefore, we frame the equation as shown below to calculate "x"
1/18 * x = 8
x = 18*8 = 144
Number of bowls of cereal Nathan ate in a year = 144 bowls

Step-by-step explanation:
We are given that an open box is to be constructed from a square piece of sheet metal by removing a square side 6 feet from each corner and turning up the edges.
We have to find the dimensions of the sheet metal
Let x feet be the side of square metal sheet
Length of box=x-12 feet (because 6 feet removed from each corner)
Width of box=x-12 feet
Height of box=6 feet
Volume of box=864 cubic feet
We know that volume of cuboid=
Box is in cuboid shaped
Therefore, volume of box=
Then ,
x=0 is not possible because side of square metal sheet can not be zero
Therefore, x=24
All sides of square metal sheet are equal.
Hence, side of square metal sheet =24 feet
Final answer:
The original sheet of metal from which an open box holding 864 cubic feet is constructed by removing 6-foot squares from each corner and folding up the edges should be a square with a side length of 26 feet.
Explanation:
To answer your question about the open box constructed from a square piece of sheet metal, let's assume the original side length of the sheet metal is x feet. When squares of length 6 feet are removed from each corner and the edges are turned up, we're left with a box with length and width of (x - 2*6) feet and height of 6 feet.
Given that the volume of the box is 864 cubic feet, we set up this equation to find x:
(x - 12 feet)(x - 12 feet)*6 feet = 864 cubic feet.
Solving this equation gives us a value for x, which is the side length of the original square piece of sheet metal. Doing the math, we find x = 26 feet. So, the dimensions of the original sheet metal are 26 feet by 26 feet.
