Answer:

125

Step-by-step explanation:

The total number of marbles is 6+10 = 16

P (black) = black / total

               = 10/16  = 5/8

With 200 draws, take the probability of P(black) times 200 since the marble is returned each time

200 * (5/8) = 125

We would expect to get 125 black marbles

Answer:

1) f

4 * ¼ = 1 (Multiplicative inverse property)

2) c

6 * 1 = 6 (Identity property of multiplication)

3) h

5 + 7 = 7 + 5 (Commutative property of addition)

4) j

If 5 + 1 = 6 and 4 + 2 = 6, then 5 + 1 = 4 + 2 (Transitive property)

5) a

4(x - 3) = 4x - 12 (Distributive property)

6) i

3(5) = 5(3) (Commutative property of multiplication)

7) k

Rules that allow us to take short cuts when solving algebraic problems.(Properties)

8) d

5 * (3 * 2) = (5 * 3) * 2 (Associative property of multiplication)

9) g

4 + (-4) = 0 (Additive inverse property)

10) e

2 + 0 = 2 (Identity property of addition)

11) b

A + (B + C) = (A + B) + C (Associative property of addition)

Find the surface area of the prism formed by the net
Lunna [17]
ANSWER

T.S.A=1960m^2

EXPLANATION

The diagram represents the net of a rectangular prism.

The dimensions are,

l=42m

w = 14m

and

h = 7m

The total surface area of a rectangular prism is given by:

T.S.A=2(lw + lh + wh)

We substitute the values to obtain,

T.S.A=2(42 \times 14 + 42 \times 7 + 14 \times 7)

T.S.A=2(980)m^2


T.S.A=1960m^2
