I have 4 hard questions here: What is x% of x?

In how how many of the ordered pairs of positive integers ( x, y ) that satisfy 2x + 3y = 9 999 999 999 999 is a x a prime number?

Each of the letters t, h, a, n, k, and s is assigned a different one of the values 1, 2, 3, 4, 5, and 6. What is the least possible value of t to the 1st power, h to the 2nd power, a to the third power, n to the 4th power, k to the 5th power, and s to the 6th power?

How many integers greater then 1 million and less than 4 million are squares of integers?

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

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,
