Answer:
Personal items=15
Step-by-step explanation:
We are given:
Total number of artifacts = 72.
We are told that 2/3 of total artifacts are shards of pottery.
We are also told that 1/8 of total artifacts are tools.
Now we will find out number of personal items by subtracting combined number of shards of pottery and tools from total number of artifacts.
Therefore, there are 15 personal items.
120
OA = OB
angle OAN = 90 degrees, so OAB and OBA is both 30 degrees.
Area shaded = Area big circle- Area of small circle;
200 pi= pi•(2x)^2 -pi•6^2;
200pi= pi•4x^2 -pi•36;
200pi=pi•4(x^2 -9) divide both sides by 4pi;
50=x^2 -9; So x=sqrt(59)~7.68cm
Answer:
3 hours
Step-by-step explanation:
Recall:
Distance = speed x time
we are given that speed = 18 km/h and distance = 54 km.
hence,
54 = 18 x time (divide both sides by 18 and rearrange)
time = 54/18 = 3 hours
<span>I will discuss polynomials. A polynomial can be
classified according to the number of expressions that it has in a given
equation. A monomial has only one expression having a coefficient (number) and
a variable (letter). A binomial has two expressions, same as the definition of
the monomial. And a trinomial has three expressions, same as the definition of
a monomial. We can determine the degree of a polynomial by looking at the
exponents of the given polynomial. If an expression has two variables with
different exponents, you can add their exponent to determine their degree.
