the number isn't large enough to round to the nearest ten thousandths.
that would be the 4th digit to the right of the decimal point, so we would need the 4th and 5th numbers to the right in order to round the answer.
Answer:
19
Step-by-step explanation:
The total area is 78 sq. ft.
Since the medal platform has different measurements, we need to individually compute the area of each polygon.
The top polygon is a square. Its sides measure 3 ft.
A₁ = a²
A₁ = 3 ft²
A₁ = 9 ft²
The middle polygon is a rectangle.
Its total width can be derived by adding the widths given and the width of the square above.
w = 3 ft + 3 ft + 3 ft
w = 9 ft
A₂ = width * height
A₂ = 9 ft * 2 ft
A₂ = 18 ft²
The bottom polygon is also a rectangle.
w = 4 ft + 9 ft + 4 ft
w = 17 ft
A₃ = width * height
A₃ = 17 ft * 3 ft
A₃ = 51 ft²
Total Area = A₁ + A₂ + A₃
T.A. = 9 ft² + 18 ft² + 51 ft²
T.A. = 78 ft²
10.5 in^2 is the skinny rectangle
104 in^2 is the boat
24 in^2 is the flag
Answer:
After 7 minutes both the tanks will have the same amount of water.
Step-by-step explanation:
The water is filling in a tank at the rate of 75 L/mins from an initial 550 L of water and water is removing from another tank at the same rate from the initial 1600 L of water.
Let us assume that the same amount of water will be there in both the tanks after t minutes.
Therefore, 550 + 75t = 1600 - 75t
⇒ 150t = 1050
⇒ t = 7
Therefore, after 7 minutes both the tanks will have the same amount of water. (Answer)
