A side of a square is 8 3/2  inches. Using the area formula A = s2, determine the area of the square.
Sedaia [141]
We are given that:
side length = 8 3/2 inches = 9.5 inches
the rule for the area is: A = s^2

Substitute with the side length in the rule given to get the area as follows:
Area = s^2 = (9.5)^2 = 90.25 inch^2

Determine whether each set of side lengths could be the sides of a right triangle. Drag and drop each set of side lengths to the
Neko [114]

Answer:

  • 10.5cm,20.8cm,23.3cm — yes
  • 6cm, 22.9cm,20.1cm — no

Step-by-step explanation:

If the sides form a right triangle, the sum of the squares of the shorter two sides will equal the square of the longest side.

1. 10.5^2 + 20.8^2 = 23.3^2 . . . . . true algebraic statement; right triangle

__

2. 6^2 +20.1^2 = 440.01 ≠ 22.9^2 = 524.41 . . . . . this is an obtuse triangle

Is 3/4 bigger than 11/16?
worty [1.4K]
Yes because if you simplify 11/16 you would not get 3/4. Or a bwtter way is if you times 4 by 4 to get 16 as a denominator, then multiply 3 by 4 it equals more than 11/16.

A room contains three urns: u1, u2, u3. u1 contains 3 red and 2 yellow marbles. u2 contains 3 red and 7 yellow marbles. u3 conta
Archy [21]

Answer:

\dfrac{11}{30}

Step-by-step explanation:

Urn U1: 3 red and 2 yellow marbles, in total 5 marbles.

The probability to select red marble is \dfrac{3}{5}=0.6.

Urn U2: 3 red and 7 yellow marbles, in total 10 marbles.

The probability to select red marble is \dfrac{3}{10}=0.3.

Urn U1: 1 red and 4 yellow marbles, in total 5 marbles.

The probability to select red marble is \dfrac{1}{5}=0.2.

The probability to choose each urn is the same and is equal to \frac{1}{3}.

Thus, the probability that the marble is red is

\dfrac{1}{3}\cdot 0.6+\dfrac{1}{3}\cdot 0.3+\dfrac{1}{3}\cdot 0.2=\dfrac{1.1}{3}=\dfrac{11}{30}.

Wpisz odpowiednie liczby: 1 cm2=...........mm2 9 cm2=...........mm2 5,2 cm2=............mm2 1 dm2 =...........cm2 17dm2=........
Tomtit [17]

Answer:

1 cm^2 = 100 mm^2

9 cm^2 = 900 mm^2

5.2 cm^2 = 520 mm^2


1 dm^2 = 100 cm^2

17 dm^2 = 1700 cm^2

4.3 dm^2 = 430 cm^2


1 m^2 = 10000 cm^2

7 m^2 = 70000 cm^2

2.5 m^2 = 25000 cm^2


1 km^2 = 1000000 m^2

50 km^2 = 50000000 m^2

8.5 km^2 = 8500000 m^2

Step-by-step explanation:

1 cm = 10 mm

1 cm^{2} = 10×10 mm^{2} = 100 mm^{2}

9 cm^{2} = 9×100 mm^{2} = 900 mm^{2}

5.2  cm^{2} = 5.20×100 mm^{2} = 520 mm^{2}


1 dm = 10 cm

1 dm^{2} = 10×10 cm^{2} = 100 cm^{2}

17 dm^{2} = 17× 100 cm^{2} = 1700 cm^{2}

4.3 dm^{2} = 4.3 × 100 cm^{2} = 430 cm^{2}


1 m = 100 cm

1 m^{2} = 100×100 cm^{2} = 10000 cm^{2}

7 m^{2} = 7×10000  cm^{2} = 70000 cm^{2}

2.5 m^{2} = 2.5×10000 cm^{2} = 25000 cm^{2}


1 km = 1000 m

1 km^{2} = 1000×1000 m^{2} = 1000000 m^{2}

50 km^{2} = 50×1000000 m^{2} = 50000000 m^{2}

8.5 km^{2} = 8.5×1000000 m^{2} = 8500000 m^{2}
