Answer:
21feet = h
The height of the pyramid is 21 feet
Explanation:
Like the volume of any pyramid and any tetrahedron, the volume is the area of the base by the height and divided by three.
a and b are the sides of the base, which is a rectangle, and therefore a*b is the area of the base.
Volume= a*b*h/3
1) The term we need to know is the h which is the height. What we are going to do is to leave alone the h in one side of the equation applying math properties.
3*V= a*b*h
What we did was to bring the 3 to the other side. It was dividing on the right side of the equiation. To go to the other side, it must multiply the term on the left.
2) Now, we need to bring the a*b to the left side. We take the term and pass it dividing the term on the left.
(3*V )/ (a*b) = h
3) Now we can use the equation to find the height.
(3*525f³) / (15f*5f) = h
21f = h
Is this a multiple choice question..?

Answer:
One reason that people may desire to migrate away from metropolitan areas is an overcrowding population.
Explanation:
While living in a metropolitan area has many benefits (career and education opportunities for example) most people end up leaving because the busy atmosphere isn't for them. Whether there is a lack of sanitation from overcrowding, noise at all hours of the night, or the size of the population isn't desirable.
I'm also going to assume this is for AP Human Geography, a test I took a few years ago and passed :)
Ang emperyo ng Tsina ay sinakop ng halos 120,000 Manchus. ... Noong 1644, sinamantala ng Manchus ang paghihimagsik at kaguluhan sa emperyo ng Tsina at lumipat sa timog. Bumubuo ng isang alyansa sa isang loyalistang heneral ng Ming, pumasok sila sa Beijing noong Hunyo at halos agad na kumuha ng kapangyarihan para sa kanilang sarili.
Ang Manchu Conquest ng Tsina ay na-spark noong Abril 1618 nang magpalabas ng proklamasyon ang pinuno ng tribong Jurchen na si Nurhaci mula sa rehiyon ng Manchurian na naglilista ng pitong mga hinaing laban sa naghaharing dinastiyang Ming.
