The answer is A because it's the only one that actually makes sense anyway
Answer:
B
Step-by-step explanation:
The answer is B because if you move two times to the right it gives you 0.09 like the eqution.
But scientific notation requires number without decimal, so the answer cannot be E because 0.9 is a decimal.
Just reminder: B and D have the same result!! just different coefficient
This is a ratio problem. You only need solve the ratio of the sand.
<u> 48 </u> <u /> = <u> n </u> <u />
1 156
(48)(156) = 1(n) (cross multiplying)<span>
</span>
7,488 pounds
To check: The pool deck is 156 times larger than the original amount of concrete so the amount of sand needs to be 156 times more.
Answer:
Step-by-step explanation:
125x^9 = (5x^3)^3
64y^12 = (4y^4)^3
If you want that factored it is
(5x^3 + 4y^4)( (5x^3)^2 - 5x^3*4y^4 + (4y^4)^2 )
(5x^3 + 4y^4)( 25x^6 - 20x^3y^4 + 16y^8)
