Which rational number is one tick mark to the right of Negative 6 Over 4 on the number line below?
murzikaleks [220]

Answer:

The number line is missing, but as we are know that the number marked in the number line is -6/4, i will guess that the ticks are spearated by fourts (the distance between each tick is 1/4).

Now, for the number at the right of -6/4, we should add the distance for one tick, this means that the number at the right is:

-6/4 + 1/4 = -5/4.

Now i will give some other examples:

Now, if the distance between ticks is 2/4, then the number at the right will be:

-6/4 + 2/4 = -4/4 = -1

Now, if the distance between ticks is 3/4, the the number at the right will be:

-6/4 + 3/4 = -3/4.

The price of a gallon of unleaded gas has dropped to 2.84 today. Yesterday's price was 2.89. Find the percentage decrease. Round
goldfiish [28.3K]

Answer: Answer: 2.1 %

Step-by-step explanation:

Decrease = initial price - final price

% decrease = [ (initial price - final price)  / initial price ] *100

% decrease =[ (2.89 - 2.83) / 2.89] * 100 =  2.08, which can be rounded to 2.1

PLEASE HELP I ONLY HAVE AN HOUR ​
skelet666 [1.2K]

Answer:

A. I can't quite see the question, but I'm pretty sure it's A

Step-by-step explanation:

Sin(A) = 1/3

Sin^2(A) + Cos^2(A) = 1

(1/3)^2 + cos^2(A) = 1

1/9 + cos^2(A) = 1

cos^2(A) = 1 - 1/9

cos^2(A) = 8/9

cos(A) = √(8/9)

√8 = √(2 * 2 * 2) = 2√2

√9 = 3

cos(A) = 2√2/3

(275)x=6,050

x=6,050/275=\$22

The answer is there pls just show your work on how to do it
Vikentia [17]

Answer:

Y=2x+0

Step-by-step explanation:

First you have to find the slope of the graph or the rise over run, which in this case is 2

Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.

To double check our work take a random point on x axis. I chose the point 1,2

fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct
