a lab technician mixed a 690 ml solution of water and alcohol, if 3% of the solution is alcohol, how many milliliters of alcohol were used and how many milliliters of water were used?

Answers

Answer 1

Answer:

To get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do this, we will get 20.70, which means that 20.70 milliliters of alcohol were used. On the other hand, we can get the milliliters of water used through two ways: the first one is by simply subtracting 20.70 from 690, which will give us the answer 669.30. Another would be by multiplying 690 by 0.97, which will also yield the answer 669.30. The number of milliliters of water used was 669.30.

If 19 more than 2 times a number is 23, what is the number?

Answers

2 is the unknown number.

Let x be the unknown number.

2x + 19 = 23
2x = 23 - 19
2x = 4
2x/2 = 4/2
x = 2

to check:
2(2) + 19 = 23
4 + 19 = 23
23 = 23

The lengths of the sides of a triangle are 3, 4, 5. Can the triangle be a right triangle?

Answers

Yes, this is a typical pythagorean triad.

Since the theorem is: $c^(2) = a^(2) + b^(2)$
And by inspection, $5^(2)$ would be the hypotenuse,
$5^(2) = 3^(2) + 4^(2)$
25 = 9 + 16
RHS = 9 + 16 = 25 = LHS
Therefore, we have proved that the values fit into pythagoras' theorem, which means that the triangle is a right triangle (that is the central idea of this theorem).

Answer:

Yes

Step-by-step explanation:

James Smith and Bill Ross purchased a property together for their business venture with stated proportionate interest of 1/3 and 2/3 respectively without the right of survivorship. Each of them wants his share to be inherited by his wife. They are a partnership and not a corporation. James and Bill most likely took title as:_________A) joint tenants.
B) tenants in common.
C) in severalty.
D) a general partnership.

Answers

Answer:

B) tenants in common.

Explanation:

There were two men, first was James Smith, and second was Bill Ross who bought a property mutually for their business venture by declared proportionate interest of 1/3 as well as 2/3 sequentially without the right regarding survivorship. Both of them want their shares to be acquired by their spouses'. Both hold a partnership but not a company. James, as well as Bill, most likely took the title as tenants in common.Because tenants in common possess versatility in whence they divide control as well as assign the rights concerning survivorship. Joint tenants, on the different hand, keep the property in similar shares while a common partnership is a business unit serving separate sharers. Severalty, as asserted beforehand, is individual ownership.
