Answer:
A Book cover costs = 8.70
A Binder costs = 8.80
8.70 + 8.80 = $17.5
For Brianna
A Book cover costs = 13.75
A Binder costs = 16.75
13.75 + 16.75 = $30.50
For Britney
x = 20. 20% of 35 is also 7. (i am not 100% sure)
The complete question in the attached figure
we know that
When we know <span>two sides and the included angle the formula for calculate the area is
</span>Area=(1/2)*a*b*sin C
in this problem
let
a=20
b=12
C=68°
Area=(1/2)*20*12*sin 68°------> Area=111.26 units²-----> Area=111.3 units²
the answer is111.3 units²
Answer:
Number of Solutions
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.
