Answer:

The amount of acid in third container is =42%

Step-by-step explanation:

Given , one container is filled with a mixture that is 30% acid a second container filled with a mixture that is 50% acid and the second container 50% larger than the first .

Let, the volume of first container is = x

Then , the volume of second container = (x+ x of 50%)

                                                                 = x + 0.5 x

                                                                 = 1.5 x

Therefore the amount of acid in first container =x \times \frac{30}{100} = 0.3 x

The amount of acid in second container =1.5x \times \frac{50}{100}  = 0.75x

Total amount of acid= 0.3x + 0.75x = 1.05 x

Total amount  of solution = x+1.5x = 2.5x

The amount of acid in third container is = \frac{1.05x}{2.5x} \times 100% %

                                                                     = 42%

Solve the equation using the distributive property and properties of equality.
tamaranim1 [39]

Answer:

x=30

Step-by-step explanation:

1 / 2 ( x + 6) = 18

Distribute

1/2x +3 = 18

Subtract 3 from each side

1/2x +3-3 = 18-3

1/2x = 15

Multiply each side by 2

1/2x*2 =15*2

x = 30

What are the factors of 2x2 3x – 54? Select two options. 2x – 9 2x – 6 2x 6 x – 6 x 6.
Makovka662 [10]

The factors of expression 2x^{2} +3x-54 are (x+6) and (2x-9).

The given expression is: 2x^{2} +3x-54

<h3>What is a factor?</h3>

A factor is a number that divides another number leaving no remainder.

We can rewrite the given expression as:

2x^{2} +12x-9x-54 (middle term has been splitted)

Take 2 as common from first two terms while take -9 as common from last two terms.

2x(x+6)-9(x+6)

Take (x+6) as common

(x+6) (2x-9)

So, we got the factors (x+6) and (2x-9)

Therefore, The factors of expression 2x^{2} +3x-54 are (x+6) and (2x-9).

Reika [66]

Answer:

Probability=0.8413

So option A is correct.

Step-by-step explanation:

In order to find the probability that the criminologist will classify all of them as delinquents, we will proceed as following:

We are required to find:

P(m>=75|m-N(80,5))

it can be written as:

1-P(m<75|m-N(80,5))

P(m<75|m-N(80,5)) can be solved as

Z=(75-80)/5

Z=-1

Probability = 1-Z(-1)

Fromm distribution table:

Probability=1-0.15866

Probability=0.8413

So option A is correct.
