Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)?

Answers

Answer 1

Answer: 6.8 x 10^13 = 68,000,000,000,000
9.46 x10 ^12 = 9,460,000,000,000

6.8 x 10^13 * 1 light year / 9.46 x 10^12 = 7.188 light years.

It affects the answer because parentheses signifies or implies that yoy are doing the operation inside of their that step comes first because if you forget about that step and move on it will affect your answer and you will get it wrong write this down

Hi there again! Anyways the answer is simple. The parenthesis r there for a reason. It is to show that that part is the one that u have to do first. So if the problem was (5-3)-1+2 u would have to do the parenthesis part first or u would get the wrong answer. I hope this helped u!

Find the percent cost of the total spent on each equipment $36, fees $158, transportation $59A. 14%, 62%, 23%
B. 15%, 60%, 35%
C. 10%, 70%, 20%
D. 11%, 62%, 27%

Answers

Answer: Therefore, Option 'A' is correct.

Step-By-Step explanation:

Since we have given that

Amount spent on equipment = $36

Amount spent on fees = $158

Amount spent on transportation = $59

Total amount spent by them is given by

$36+158+59=\$253$

Percent cost of equipment of the total amount is given by

$(36)/(253)* 100=14.2\%$

Percent cost of fees of the total amount is given by

$(158)/(253)* 100\n\n=62.45\%$

Percent cost of transportation of the total amount is given by

$(59)/(100)* 100\n\n=23.3\%$

Hence, Percent cost of the total spent on each is

14%, 62%, 23%.

Therefore, Option 'A' is correct.

How do I solve A B C ?

Answers

Answer:

see explanation

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

Thus CO = OA = a

(a)

CA = CO + OA = a + a = 2a

(b)

AB = AO + OB = - a + b = b - a

(c)

BC = BO + OC = - b - a

Answer:

(a) CA=CO+OA=a+a=2a

(b) AB=AO+OB=-a+b=b-a

Step-by-step explanation:

a) CA=CO+OA=a+a=2a

(b) AB=AO+OB=-a+b=b-a
