Step-by-step explanation:

6. 0 ,234,560 is divisible by 2.

7. 389,570 is divisible by 5.

8. 630,620 is divisible by 10.

9. 6+1+1+8+1=17 +(1)

611,811 is divisible by 3.

10. 5+2+5+4+3=19

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.

Triangle IJK is similar to triangle LMN. Find the measure of side LM. Round your answer to the nearest tenth if necessary.

Andre45 [30]

Answer:

It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.

Step-by-step explanation:

Since they are similar, they are proportional.

54/11=4.90909091 or 4.9

Multiply 11 by 4.90909091 and you get 54

Multiply 8 by 4.90909091 and you get 39.3

if you multiply by 4.9 you get 39.2
