assume that tge volume,v, of a sphere is expanding at a rate of 100 inches cubex per minute, the volume of a sphere is given by

Zielflug [23.3K]

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\\\\
-----------------------------\\\\
\cfrac{dv}{dt}=\cfrac{4\pi }{3}\cdot 3r^2\cfrac{dr}{dt}\implies \cfrac{dv}{dt}=4\pi r^2\cfrac{dr}{dt}
\\\\\\
\cfrac{\frac{dv}{dt}}{4\pi r^2}=\cfrac{dr}{dt}\qquad 
\begin{cases}
\frac{dv}{dt}=100\\\\
r=8
\end{cases}\implies \cfrac{100}{4\pi 8^2}=\cfrac{dr}{dt}$

In a triangle, one of the angle measures 70°

Tanya [424]

Answer:

the two angles are 55° each

Step-by-step explanation:

Let the two equal angles be y each

Therefore,

70° + y + y = 180°

Collect like terms

2y = 180 — 70

2y = 110

Divide both side by the coefficient of y i.e 2

y = 110/2

y = 55°

Therefore, the two angles are 55° each
