Answer:

12.8% decrease

Step-by-step explanation:

if you find the unit rate for the sale, which would be 125 cents divided by 3 cans, equals around 43.6 cents per can. 43.6 cents is an x% decrease of 50 cents, and to find x easily i multiplied by 2. 43.6 x 2=87.2, and 50 x 2 = 100. that means that the sale price is 87.2 % of the original price, which is a 12.8% decrease.

Answer:

Total cost= $51

Step-by-step explanation:

Giving the following information:

Fixed cost= $5

From 0 to 40,000 gallons= $0.0007 per gallon

From 40,001 to infinity= $0.0009

We need to calculate the total cost for 60,000 gallons:

Total cost= 5 + 40,000*0.0007 + 20,000*0.0009

Total cost= $51

Reposting becuase it want let me edit my last one and somebody spam answered it.

Answer:

5Step-by-step explanation:

If you use the distance formula you can solve it pretty easily. The distance formula is:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2} \\$

The two points you want are A and D. A is (-1, -4) and D is (3, -1). Plug that into the formula...

d = $\sqrt{(3 - (-1))^2 + (-1 - (-4))^2}$

d = $\sqrt{4^2 + 3^2}$

d = $\sqrt{16 + 9}$

d = $\sqrt{25}$

I can solve it in a different way if you want me to.

Solve the inequality. Graph the solution set. 2r−9≤−6

Ahat [919]

We have that

2r−9≤−6------> 2r ≤ -6+9-------> 2r ≤ 3-----> r ≤ 1.5

the solution is the interval (-∞, 1.5]

using a graph tool
see the attached figure
