A supermarket reduced the price per pound whole chicken by 20%. How many pounds of chicken can now be purchased for the amount o
nignag [31]

Answer:

25 pounds

Step-by-step explanation:

Let us assume that initially, 1 pound of whole chicken costs x.

So, initially 20 pounds of whole chicken costs 20x.

Now, the price is reduced by 20%.

That means that 1 pound of whole chicken now costs  x[1-\frac{20}{100} ]=0.8x

Therefore, with a 0.8x amount of money, we can now purchase 1 pound of the whole chicken.  

Hence, with a 20x amount of money, we can now purchase \frac{20x}{0.8x}=25 pounds of the whole chicken.

Complete the square to transform the quadratic equation into the form (x –p)2= q.X2-8x -10 = 18
spayn [35]

Answer:

(x-4)^{2}=44

Step-by-step explanation:

we have

x^{2}-8x-10=18

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2}-8x=18+10

x^{2}-8x=28

Complete the square . Remember to balance the equation by adding the same constants to each side

x^{2}-8x+16=28+16

x^{2}-8x+16=44

Rewrite as perfect squares

(x-4)^{2}=44

Which equation can be used to find x the length of the hypotenuse of the right triangle?
-BARSIC- [3]

Answer:

<h2>Explanation:</h2>

For any right triangle, the longest side is called the hypotenuse. Therefore, by Pythagorean theorem it is true that:

x^2=a^2+b^2

Where:

x: Hypotenuse

a, b: The other two sides.

For instance, if we have a right triangle whose sides measure:

a=3 \\ \\ b=4

Then, the hypotenuse can be found as:

x=\sqrt{3^2+4^2} \\ \\ c=\sqrt{25} \\ \\ c=5

Why don't we use the Richter scale anymore?
Ratling [72]

Answer:

The Richter scale was abandoned because it worked best for earthquakes in southern California, and only those hitting within about 370 miles (600 kilometers) of seismometers. These days, scientists detect temblors on the other side of the Earth. In addition, the scale was calculated from one type of earthquake wave, a kind that doesn't help much when measuring truly massive quakes, like Japan's magnitude-9 in 2011. So seismologists created a new scale, called the moment magnitude scale. The moment magnitude scale captures all the different seismic waves from an earthquake, giving a better idea of the shaking and possible damage.
