Use the identity: a^3 + b^3 = (a + b)(a^2 - ab + b^2)
Replace b^3 by 27y^3
x^3 + 27b^3 = (x + 3y)(x^2 - 3xy + 9y^2)

Kruka [31]
Let's remember that V = lwh. If you are given two other measurements, you can multiply those two and divide V by that quantity to solve for the missing variable. Same process no matter the value:)

The list of numbers 41, 35, 30, X, Y, 15 has a median of 25. The mode of the list of numbers is 15. To the nearest whole number,
lara [203]

Answer:

C) 26

Step-by-step explanation:

41 , 35,30 , X , Y ,15

Number of data's = 6. So, median will be the average of (\dfrac{6}{2})^{th} \ and \ (\dfrac{6}{2}+1)^{th} \ term . 3 and 4th term

Median = \dfrac{30+X}{2}

\dfrac{30+X}{2}=25\\\\

30 + X = 25*2

30 + X = 50

       X = 50 - 30

X = 20

Mode is 15

So, Y = 15

41,35,30,20,15,15

Mean =\dfrac{41+35+30+20+15+15}{6}= \dfrac{156}{6}=26

Omlll I need help with all of these but like you don’t have to answer all of them lol
krok68 [10]

Answer:

For 17 the first answer is 1(1/20). The picture can be misleading because the flags are at the same height and the American flag's pole looks shorter. This is only because it is behind the Floridian flag and because the perspective isn't accurate to compare them.

Step-by-step explanation:

The mixed fraction would be 1(5/100) which can be simplified when you divide the fraction by 5 into 1(1/20).
