Answer

1.  13,828

2.  516

Step-by-step explanation:

Ver 1 :

2s^3 + r - t

2s^3 = 24^3

24^3= 13,824

13,824 + r - t = 13,824 + (-3) - (-7)  

13,824 + (-3) - (-7)  = 13,828

Ver 2:

2s^3 + r - t

2s^3 = 2 x 4^3

2 x 4^3 = 512

512 + r - t = 512 + (-3) - (-7)

512 + (-3) - (-7) = 516

A bag contains 15 marbles. The probability of randomly selecting a green marble is One-fifth. The probability of randomly select
dsp73

Given:

Total number of marbles = 15

Probability of randomly selecting a green marble = \dfrac{1}{5}.

Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble = \dfrac{2}{25}.

To find:

The number of blue marbles.

Solution:

Let the number of blue marbles be x.

\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}

P(Blue)=\dfrac{x}{15}

It is given that,

P(Green)=\dfrac{1}{5}

Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is \dfrac{2}{25}. So,

P(Green)\times P(Blue)=\dfrac{2}{25}

\dfrac{1}{5}\times \dfrac{x}{15}=\dfrac{2}{25}

\dfrac{x}{75}=\dfrac{2}{25}

Multiply both sides by 75.

\dfrac{x}{75}\times 75=\dfrac{2}{25}\times 75

x=2\times 3

x=6

Therefore, the number of blue marbles in the bag is 6.

Mr.Richard has an orchard of length and breadth 280m and 200m respectively. He wants to fence it with 4 rounds of barbed wire. F
sesenic [268]

Answer:

$109.71

Step-by-step explanation:

first we find the perimeter

=2(280+200)

=2×480

=960m

now we multiply it by 4 as he wants it 4 times around

960×4

3840

now we find the fencing cost

since 35 per meter we divide it by 35

3840/35

=$<u>109.71</u>
