Answer:

8. \frac{8r^{2} }{q^{2} }

10. 12x^{-1} y^{6} z

Step-by-step explanation:

8. \frac{16p^{6}qr^{8}  }{2(p^{2}qr^{2})^{3}  } = \frac{16p^{6}qr^{8}  }{2p^{6}q^{3}r^{6}  }= \frac{8r^{2} }{q^{2} }

10. 4x^{2} y . 3 (-2x^{4} y)^{0} . x^{-3} y^{5} z = 4x^{2}y . 3(1) . \\x^{-3} y^{5}z = \\12x^{-1}yx^{6}z

648 ÷ 8 tell how you solved pls i need help
stira [4]

Answer:

The answer is 81

Step-by-step explanation:

All you have to do is create your long division chart with 648 inside and 8 on the outside 8 can not go into 6 but it can go into 64 so 8 goes on top of 4 you subtract 64 minus 64 becayse 8 times 8 is 64. Lastly you bring down the other 8 and 8 goes into 8 once so you put 1 on top. And so thats how you get 81.

Pls someone help me find the answers
Alecsey [184]

Answer:

x = 145°

Step-by-step explanation:

We know that y = 98°, so we can find ∠DBC:

180°-y = ∠DBC

180°-98° = 82°

We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.

∠DBC + z = x

82°+63° = x

x = 145°

Which of the following demonstrates how the 20 is calculated using the<br> combination pattern?
ZanzabumX [31]

Answer:

D

Step-by-step explanation:

The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.

The entry in the n^{th} row (start counting rows from 0) and k^{th} column (start counting columns from 0) of Pascal's triangle is denoted by

C^n_k=\left(\begin{array}{c}n\\ k\end{array}\right)

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.

Hence,

20=C^6_3=\left(\begin{array}{c}6\\ 3\end{array}\right)=\dfrac{6!}{3!(6-3)!}
