Let:
Vbu= Volume of the buret
Vbk= Volume of the beaker
A buret initially contains 70.00 millimeters of a solution and a beaker initially contains 20.00 ml of the solution the buret drips solution into the Beaker. each drip contains 0.05 mL of solution, therefore:
x = Number of drips
a = volume of each drip
after how many drips will the volume of the solution in the buret and beaker be equal ? Vbu = Vbk:
13. 80 + 60 - 140. 180 - 140 = 40 degrees.
14. 90 + 160 + 85 = 275. 360 - 275 = 85 degrees.
16. 105 + 60 + 120 + 115 = 400. 450 - 400 = 50 degrees.
17. 180 - 110 -70 / 2 = 35. 180 - 35 = 145 degrees.
Hope this helps.

14.63
Step-by-step explanation:
Answer:
(or 2352637)
Step-by-step explanation:
(or 2352637 for exact value)
Firstly, we will find slope of the given lne
we can select any two points from the graph
(-4,-5) and (4,-1)
so, x1=-4 , y1=-5 m x2=4 , y2=-1
now, we can use formula
now, we can plug values
(B)
we are given
line parallel to the nline shown
and we know that
slope of two parallel lines are always equal
so, slope will also be
we have point as (3,4)
now, we can use point slope form of line
we can plug values
we get
(D)
we have point as (-3, 2)
and we know that
slope of perpendicular line is -1/m
so,
now, we can use point slope form of line
we get
