Simplify 7 square root 2535

Answers

Answer:

The value of 7 square root 2535 is 352.443 or $91√(15)$ .

Step-by-step explanation:

Consider the provided expression.

$7√(2535)$

The value of $√(2535)$ is 50.349 approximately or 13√15

Now substitute the value of $√(2535)$ in above expression.

$7* 50.349$ or $7* 13√(15)$

$352.443$ or $91√(15)$

Hence, the value of 7 square root 2535 is 352.443 or $91√(15)$ .

7*sqrt(3*5*13^2) = 91*sqrt(15) = 91*3.872983346 = 352.4414845

b. writing the Principia Mathematica

c. confirming that the earth revolves around the sun

Question 3.3. Which best describes the influence of Isaac Newton's theory of universal gravitation?

Answers

1. Which describes the work of Nicolaus Copernicus?
c. developing a heliocentric theory

2. Which was not an accomplishment of Galileo Galilei?

c. confirming that the earth revolves around the sun

3. Which best describes the influence of Isaac Newton's theory of universal gravity?

It showed that the universe follows a set of predictable rules

Final answer:

Nicolaus Copernicus developed the heliocentric theory. Galileo Galilei did not write the Principia Mathematica but he did confirm the earth revolves around the sun with his improved telescope. Isaac Newton's theory of universal gravitation significantly advanced our understanding of the physical universe.

Explanation:

Nicolaus Copernicus is renowned for developing the heliocentric theory, according to which the sun is the centre of the universe and the earth and other planets revolve around it. This answer corresponds to option C in your question. Galileo Galilei, on the other hand, did not write the Principia Mathematica. This work was written by Sir Isaac Newton, and thus corresponds to option B of your second question. Galileo is well-known for advancing the telescope technology, and his observations confirmed the heliocentric system.

As for your third question, Isaac Newton's theory of universal gravitation revolutionized our understanding of the physical universe. While it did lead to new insights into light, it's most significant contribution is perhaps its explanation of how objects in the universe are attracted to each other, demonstrating that the same forces are at work in the heavens and on earth.

How do you do the work for

$43 dinner; 18% gratuity

Answers

The total cost of the dinner with gratuity is $50.74Add the gratuity to the regular price. Method 2: Add the percent of gratuity to 100%. 100% + 18% = 118% The total cost is 118% of the bill. Method 1: Add gratuity to the regular price. Find the gratuity.

Start by calculating just the gratuity by itself. We know its 18% of $43. Another way to write 18% is 0.18 so:
$G=$43 * 0.18$
$G=$7.74$

So just the gratuity by itself is $7.74. If you want to know the entire bill you can add up the meal and the gratutiy like so

$T= Meal + Gratuity$
$T = 43 + $7.74 = $50.74$

Another way to do it is to recognize that you are paying for 100% of the meal and then paying antoher 18% AGAIN for a total of 118% or 1.18. If you do this you get the same answer:

$$43 * 1.18 = $50.74$
