Answer: 3x3=9, 4x5=20, 8x9=72, and 7x3=21!
Step-by-step explanation:
Answer:
M is not parellel to N because they do not create supplementary angles with the lines that it passes through.
J and K are parallel to each other because they create supplementary angles with line m
supplementary angles add up to 180 and if parallel lines create supplementary angles with the line they cross then they are parallel to each other if that makes sense
105+75=180

Answer:
the answer is true
Step-by-step explanation:
(I would recommend changing the wording a bit.)
At 11 am Lacy get's paid around 50 dollars for something such as work. The money sits in her purse until 1:15pm when she pays for something such as food.
We are given with the following given
dV/dt = 35 m3/min
h = (3/2)D
What is asked is
dr/dt at t = 7 min
The volume of a cone is
V = (1/3)πr²h
From the given
h = (3/2)D
since D = 2r
h = 3r
Subsituting
V = πr³
At t = 7 min, the volume is
V = 35(7)
V = 245
and the radius is
245 = πr³
r = 4.27
Differentiating the volume
dV/dt = 3πr² dr/dt
From the given
dV/dt = 35
Subsituting
35 = 3πr² dr/dt
So,
dr/dt = 0.20 m/s
and
dh/dt = 0.60 m/s
