A light year is the distance that light travels in one year. Find the number of miles in a light-year if light travels 1.8x10^5 mi per sec.

Answers

Answer:

5.67648 * 10^12 miles

Step-by-step explanation:

Given that:

Speed of light = 1.8x10^5 mi per sec.

The number of miles in a light year will be :

Distance = speed * time

The time in seconds in a year is :

365 days * 24 hours * 60 mins * 60 sec = 31536000 seconds

Hence,

The number of miles in a light year :

1.8x10^5 * 31536000 = 5676480000000

= 5.67648 * 10^12 miles

Function g decreasing over the interval (negative infinity, 0) .
The range of function g is (3, infinity) .
Function g is positive over the interval (negative infinity, infinity) .

Answers

Answer:

A,B,D,E

Step-by-step explanation:

The statements which are true shown below,

Function g is 4 units above function f.Function g has a y-intercept of (0,4)The range of function g is (3, ∞).Function g is positive over the interval (-∞ , ∞ ).

From graph attached below, It is observed that

Graph of function g is 4 units above the graph of parent exponential function.Domain of the function is defined as all the input values for which function is defined. From graph of function g, the domain of function is (-∞ , ∞ )The y- intercept is the point at which graph of function crosses the y-axis. Graph of function g crosses y-axis at (0, 4). Therefore, Function g has a y-intercept of (0,4).Function g increasing over the interval (-∞, 0) .Range of function is known as output values of function. From graph, it is observed that the range of function g is (3, ∞).Since, graph of function g is above x- axis. Therefore, Function g is positive over the interval (-∞ , ∞ ).

Answer: a = -3

Step-by-step explanation:

first, we remove the parentheses.

4 - 9/5a - 12/5 = 7

then, we calculate.

8/5 - 9/5a = 7

next, we multiply both sides.

8 - 9a = 35

then, we move the constant to the right.

-9a = 35 - 8

next, we calculate.

-9a = 27

finally, we divide both sides.

a = -3

Answers

Answer:

$27.59

Step-by-step explanation:

You multiply 30 dollars by 0.85 (1-0.15, with the 0.15 being for the 15 percent off). Which gets you to $25.50, and you then multiply it by 1.082 (the 1.082 being the tax, and the .082 part equating to the 8.2% tax percentage).

Ally has 8 red marbles and 16 green marbles. She also has red bags and green bags. She wants to put marbles in the bags that match their color. Each bag will have the same number of marbles. What is the largest number of marbles she can put into each bag?

Answers

Answer:

The largest number of marbles she can put into each bag is 8 marbles.

Step-by-step explanation:

We solve the question above using Greatest common factor method

We find the factors of 8 and 16 and the Greatest number common to both factor is our answer.

Hence:

The factors of 8 are: 1, 2, 4, 8

The factors of 16 are: 1, 2, 4, 8, 16

Then the greatest common factor is 8.

Therefore, the largest number of marbles she can put into each bag is 8 marbles.

Over a one week period in the summer, the price of a gallon of gas increased from $2.35 to $2.82. By what percent did the price of gas increase over that week?

Answers

The price of gas increases from $2.35 to $2.82 or by $0.47 ($2.82 - $2.35 = $0.47).
The increase as a percentage of the original price is given by
($0.47/$2.35) x 100% = 20%

The answer is 20%
Hope this helps :)

The percentage increase from $2.35 to $2.82 over the week in summer is 20%

Given Data

Initial Value = $2.35

Final Value = $2.82

We know that the expression for Percentage increase is given as

% Increase = Increment/Initial Value *100

% Increase = 2.82-2.35/2/35 * 100

% Increase =0.47/2/2.35 * 100

% Increase =0.2* 100

% Increase = 20%

Hence the percentage increase is 20%
