Answer:

23% of Michael's rock collection is metamorphic rock.

Step-by-step explanation:

We are given the following in the question:

Percentage of igneous rock in the collection = 27%

Percentage of sedimentary rock in the collection = 50%

Remaining rocks are metamorphic rock.

Total collection = 100%

Percentage of metamorphic rocks =

=100\%-(27\%+50\%)\\=100\%-77\%\\=23\%

Thus, 23% of Michael's rock collection is metamorphic rock.

What is y - 8 = -1/2 (x + 4) in standard form (8th grade math)
Scilla [17]
This equation is in point-slope form. To change it to standard form, you must distribute -1/2 to (x+4) to get -1/2x-2. Your equation should now be y-8 = -1/2x-2. You should then add 1/2x to both sides (to cancel out -1/2x on the right side). Now, you should have y+1/2x-8 = -2. Finally, add 8 to both sides (to cancel out -8 on the left side) and flip the x and the y to get a final answer of 1/2x+y = 6.

Airida [17]

Step-by-step explanation:

gostĭ is “guest,” whereas that of Latin hostis is “enemy.” To explain the connection between “guest” and “enemy” it is usually supposed that both derived their meaning from “stranger,” a sense which is still attested in Latin. The notion “favorable stranger” developed to “guest”; that of “hostile stranger” to “enemy.”
