Answer:
48 minutes
Step-by-step explanation:
39% of 122 is ...
0.39 × 122 = 47.58 ≈ 48
Holly has watched about 48 minutes of the movie.
Bottom = 2x5 = 10ft
Middle = 2x6 ( 4+2) = 12
Top 4x2= 8
10ft+12ft+8ft= 30ft squared
-8/5x is the slope of the line.
Answer:
Yes. It is a vector space over the field of rational numbers 
Step-by-step explanation:
An element
of the set
has the form

where
are rational coefficients.
The operations of addition and scalar multiplication are defined as follows:


The properties that
, together the operations of vector addition and scalar multiplication, must satisfy are:
- Conmutativity
- Associativity of addition and scalar multiplication
- Additive Identity
- Additive inverse
- Multiplicative Identity
- Distributive properties.
This is not difficult with the definitions given. The most important part is to show that
has a additive identity, which is the zero polynomial, that is closed under vector addition and scalar multiplication. This last properties comes from the fact that
is a field, then it is closed under sum and multiplication.
the answer would be 1.52 because first, we would turn 60% into a decimal (.60) and then, we would multiply .95x.60 and we would get .57
next, we would add .95 and .57 together to get 1.52
