Ardie bought 547 acres of land for development. If 29 acres of his purchase is reserved for a park, how many two-acre building l
9966 [12]

Hey there!


First, is he used 29 out of the 547 for a park, he can't use them for two acre building lots, so we must subtract:


547-29 = 518


If we want to know how many 2 acre building lots we can sell, we can divide 518 by 2, as dividing it by 2 sees how many times 2 goes into 518- essentially how many two acre lots are in 518 acres.


This gives us 259 two-acre building lots.


Hope this helps!

amid [387]

Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle

Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.

The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
