Answer:
(E) 9
Step-by-step explanation:
A= 4
B= 5
C= 0
a+b+c= 4+5+0= 9
a+b=9= 4+5=9
a+c=4= 4+0=4
b+c=5= 5+0= 5
According to the question requirements
v= 4/3*pi*r^3
dv/dt = 4*pi*r^2*dr/dt
when
d= 1.7
r= 0.85
and
dv/dt = 2
2= 4*pi*(0.85)^2*dr/dtthus the the speed of increasing of the balloon's diameter is
dr/dt = 1/(2pi*(0.85)^2)
=<span>0.2203 ft/min</span>
Answer:
6 is answer
Step-by-step explanation:
x+3=9
or, x=9-3(because we have to change sign)
therefore, x=6ans//
Answer:
1.76
Step-by-step explanation:
3.9-7.4x=-4.5x+9
-2.9x=5.1
x=1.758 or 1.76
