The table shows the number of words a person types of different amounts of time. What is the rate of words per minute?

35 words per minute.

Step-by-step explanation:

To find the answer you have to divide Minutes by Words Typed.  

105 ÷ 3 = 35.

175 ÷ 5 = 35.

315 ÷ 9 = 35.

Therefore, our answer is 35.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

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,
