<span>Your answer is very simple. It is 550 decimeaters.
</span><span>A Hectometre (1 Hm) is 100 m so 0.55 Hm = 55 m; 1 decimetre = 0.1 m so 55 m = 55 x 10 dm = 550 dm</span>

The conversion from hectometers to decimeters may be done by proper dimensional analysis and the conversion factors. Each hectometer is composed of 100 meters and each meter is composed of 10 decimeter. From this,
                       (0.55 Hm) x (100 m / 1 Hm) x (10 dm / 1 m) = 550 decimeter
Thus, 0.55 hectometer is equal to 550 decimeters.

the total amount of flour in a bakery after receiving new stock equal to 3/10 of its current stock (x)
Ivenika [448]

If you're look for an equation to find how much flour there would be :

y would be the flour in the bakery after a certain number of stocks based on x, the number of times the flour has been stocked. The equation would require the initial amount of flour, though, which you have not provided.

the constant 1.3 will be used to show that the stock is increasing by 30% each time while including the initial amount of flour.

y= (initial amount of flour)(1.3)^x

Divide x4 + 7 by x - 3.. A] x³ - 3x² - 9x - 27 R 88. B] x³ + 3x² + 9x - 27 R -74. C] x³ + 3x² + 9x + 27 R 88

<span> divide a polynomial p(x) by (x-3). Add and subtract the multiple of (x-3) that has the same highest-power term as p(x), then simplify to get a smaller-degree polynomial r(x) plus multiple of (x-3). </span>

<span>The multiple of (x-3) that has x^4 as its leading term is x^3(x-3) = x^4 - 3x^3. So write: </span>

<span>x^4 + 7 = x^4 + 7 + x^3(x - 3) - x^3(x - 3) </span>
<span>= x^4 + 7 + x^3(x - 3) - x^4 + 3x^3 </span>
<span>= x^3(x - 3) + 3x^3 + 7 </span>

<span>That makes r(x) = 3x^3 + 7. Do the same thing to reduce r(x) by adding/subtracting 3x^2(x - 3) = 3x^3 - 9x^2: </span>

<span>= x^3(x - 3) + 3x^3 + 7 + 3x^2(x - 3) - (3x^3 - 9x^2) </span>
<span>= x^3(x - 3) + 3x^2(x - 3) + 9x^2 + 7 </span>

<span>Again to reduce 9x^2 + 7: </span>
<span>= x^3(x - 3) + 3x^2(x - 3) + 9x^2 + 7 + 9x(x - 3) - (9x^2 - 27x) </span>
<span>= x^3(x - 3) + 3x^2(x - 3) + 9x(x - 3) + 27x + 7 </span>

<span>And finally write 27x + 7 as 27(x - 3) + 88; </span>
<span>x^4 + 7 = x^3(x - 3) + 3x^2(x - 3) + 9x(x - 3) + 27(x - 3) + 88 </span>

<span>Factor out (x - 3) in all but the +88 term: </span>
<span>x^4 + 7 = (x - 3)(x^3 + 3x^2 + 9x + 27) + 88 </span>

<span>That means that: </span>
<span>(x^4 + 7) / (x - 3) = x^3 + 3x^2 + 9x + 27 with a remainder of 88</span>
