There are 29235 marbles and 371 jacks. If you want to know the percentage of jacks, do you divide the first number by the second

garik1379 [7]

Answer:

Correct answer: Two decimal places to the right

Step-by-step explanation:

We will set the classic proportion:

29,235 - 100%

371 - x%

29,235 : 371 = 100 : x ⇒ 29,235 · x = 371 · 100

x = (371/ 29,235) · 100 = 0.0127 · 100 = 1.27%

x = 1.27%

You divide first number by the second and then multiply with 100,

which is the same as moving the decimal point two places to the right.

God is with you!!!

Wind farms are a source of renewable energy found around the world. If a turbine generates 500kW in a 10m/s wind, how much power

Annette [7]

<span>Wind farms are composed of tens of wind mills that us electric generator to harness the power of the wind. The power that comes out of the electric generators should be proportional with the force or the wind which is also proportional to the speed of the wind. Considering that a 10 m/s generates 500 kW, than a 12 m/s wind should generate somewhere around 600 kW.</span>

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(

salantis [7]

Answer:

There are no simple factors to this expression. You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:

$y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}$

Convert 7 pounds 3 ounces to

svetoff [14.1K]

7 pounds and 3 ounces equal to 3.27 kg

Step-by-step explanation:

We need to convert 7 pounds and 3 ounces to kilograms.

We know:

1 lb = 16 oz

and 1 kg = 2.2 lb

where lb stands for pounds and oz stands for ounces and kg stands for kilograms.

$16\,\,oz = 1\,\,pound\\1\,\,oz = \frac{1}{16} \,\,pound\\3\,\,oz = \frac{1}{16} * 3\,\,pounds\\3\,\,oz = 0.1875\,\,pounds$

So, Total pounds = 7+0.1875 = 7.1875

Now, Converting Pounds to kg

$2.2\,\,pounds = 1\,\,kg\\1\,\,pound = \frac{1}{2.2} \,\,kg\\7.1875\,\,pounds = \frac{1}{2.2} * 7.18757.1875\,\,pounds = 3.27\,\,kg$

So, 7 pounds and 3 ounces equal to 3.27 kg
