Answer: a = 110ᴼ
Step-by-step explanation:
The angles on each line of the figure add to equal 180ᴼ
180 - 70 = 110
a = 110ᴼ
b and 70ᴼ are vertical angles, so their measures are congruent.
b = 70ᴼ
180 - 70 = 110
c = 110ᴼ
Answer:
Jack - $28
David - $17
Step-by-step explanation:
Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.
2d-6+d=45
3d-6=45
3d=51
d=$17
We can then substitute back and find 2(17)-6=34-6=$28.

0.7 is the answer. Hope this helps
Answer: 8.3 feet
We know the area of 1 tile is:
(1)
We also know Jack used 103.75 tiles to cover the whole bathroom floor, which is a rectangle.
Remembering (1), we have that:
(2)
Which is also the area of the rectangle from which we only have the value of one of its sides, the width 
:
(3)
In addition, the area 
of a rectangle is given by the following equation:
(4)
Where 
is the length.
Substituting the value of the width written in (3) and the area (2) in equation (4):
(5)
We finally have the value of the length of the bathroom floor:
