Answer:
0.35
Step-by-step explanation:
0.25 × 1.4 =
0.25×100=25
1.4 × 10 = 14
25×10=250
25×4=100
250+100=350
25×14=350
350÷1000(0.25》25, 1.4》14)
0.35
Answer:
A
Step-by-step explanation:
Change the mixed numbers to improper fractions
7
= 
6
= 
The subtraction is then
- 
Both fractions have a common denominator so subtract the numerators leaving the denominator
=
=
→ A
For the given vectors
and 
The dot product of vectors a and b is defined as = 
So, 

= -16+12
= -4
The circumcenter is where the perpendicular bisectors meet.
if you sketch the triangle, you will see that it is a right triangle, with the right angle vertex at (2,1)
one perpendicular bisector is x=1, another perpendicular bisector is y=3
they meet at (1,3)
so (1,3) is the answer.
