Indentify the percent of change as an increase or a decrease. Then find the percent of change. Round to the nearest tenth of a percent, if necessary. 5 cups to 8 cups

60 % - percent of increase

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

For the first part, because the original number of cups increases, the percent of change is an increase.

To find the number:

(new number -original number ) / (original number) =  

Replacing with the values given:

(8-5) /5 = 0.6 (decimal form)

To obtain the percentage we have to multiply it by 100:

0.6 x 100 =60%

In conclusion, we have a 60  percent of increase.

Feel free to ask for more if needed or if you did not understand something.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
