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%

Thus, 23% of Michael's rock collection is metamorphic rock.
Answer:
d. only the first equation is an identity
Step-by-step explanation:
3.2 x 10^-2 + 3.2 x 10^-4 + 2.8 x 10^-2
= 3.2 + 2.8
= 6 x 10^-2 + 3.2 x 10^-4
Convert 3.2 into fraction which is 16/5
And express with a positive exponent using “a^-n = 1/a^n” therefore
= 6 x 10^-2 + 16/5 x 1/10^4
= 6 x 1/10^2 + 16/5 x 10^4
= 6 x 1/100 + 16/5 x 10,000
Reduce 6 and 100 with the GCF ‘2’
Then reduce 16 and 10,000 with 16
= 3 x 1/50 + 1/5 x 625
Multiply
= 3/50 + 1/3125
Then add
The answer is
= 377/6250
= 0.06032

Answer:
=-23y
Step-by-step explanation:
(-3y3-5y-2)+(-7y2+5y+2)
=-3yX3-5y-2-7yX2+5y+2
=-3X3y-5y-7X2y+5y-2+2
=-3X3y-7X2y-2+2
=-9y-7X2y-2+2
=-9y-14y-2+2
=-23y-2+2
=-23y
I hope this helps!
