Answer:

I assume that this is a math question not a chemistry question...

In math I assume the answer is 1 liter....

total = 2 liters (1 liter water 1 liter ammonia )

If this is a chemistry question there is a difference between total

volume, and total weight, which would not result in the answer being 1 liter

Select the statement that describes this expression: 5 x 3 − (2 x 4) + 5.

Mashcka [7]

Answer:

It would be subtract the product of 2 and 4 from the product of 5 and 3, then add 5 because it’s parenthesis then you would multiply/devide then add/subtract whatever comes first

Step-by-step explanation:

5x3 - (2x4) + 5

5x3 - 8 + 5

15 - 8 + 5

7 + 5

A woman invested #600,000 in a bank at the rate of 10% for 2.5 years. a. Find the Interest. b. Calculate the amount at the given

kow [346]

Here,

Principal = 600000

Rate = 10%

Time = 2.5 years

Simple Interest = ?

Amount = ?

Now,

Simple Interest = (P*T*R)/100

= (600000*2.5*10)/100

= 150000

Amount = Principal + Interest

= 600000 + 150000

= 750000

I hope you understand...

It is a Right answer...

Thanks♥♥

Which equation is equivalent to StartRoot x EndRoot + 11 = 15?

Lerok [7]

The equivalent expression of $\sqrt x + 11 = 15$ is $\sqrt x = 15 - 11$

<h3>How to determine the equivalent expression?</h3>

The complete question is in the attached image

The expression is given as:

$\sqrt x + 11 = 15$

Subtract 11 from both sides of the equation

$\sqrt x + 11 - 11= 15 - 11$

This gives

$\sqrt x = 15 - 11$

Hence, the equivalent expression of $\sqrt x + 11 = 15$ is $\sqrt x = 15 - 11$

Find sin(A), cos(A), and tan(A) for the triangle pictured

konstantin123 [22]

Answer:

See below ~

Step-by-step explanation:

sin (A) = opposing side / hypotenuse

sin(A) = 5√29

cos(A) = adjacent side / hypotenuse

cos(A) = 2/√29

tan(A) = opposing side / adjacent side

tan(A) = 5/2 = 2.5
