Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm

Answer:
16
Step-by-step explanation:
Simplify the following:
4 + 3×2^3/2
3×2^3/2 = (3×2^3)/2:
4 + (3×2^3)/2
Combine powers. (3×2^3)/2 = 3×2^(3 - 1):
4 + 3×2^(3 - 1)
3 - 1 = 2:
4 + 3×2^2
2^2 = 4:
4 + 3×4
3×4 = 12:
4 + 12
4 + 12 = 16:
Answer: 16
Answer: 28/125
Step-by-step explanation: To divide two fractions, flip the second fraction and multiply. The equation will be:
4/25 x 7/5
Multiply the numerators by the numerators and the denominators by the denominators.
4 x 7 = 28 (numerator)
25 x 5 = 125 (denominator)
Put into a fraction.
28/125
the answer is kf=8 it took me a minute to see it
