How can i multiply 9 x 475 using expanded form and distributive property

weeeeeb [17]

Expanded form: 9+400+70+5
idk distributive property sorry but I'm pretty sure you can't because in distributive, you need to have a parantheses or you could just factor but I don't think that's the case.

Suppose the radius of the sphere is increasing at a constant rate of 0.3 centimeters per second. At the moment when the radius i

elixir [45]

<h2>At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.</h2>

Step-by-step explanation:

We have equation for volume of a sphere

$V=\frac{4}{3}\pi r^3$

where r is the radius

Differentiating with respect to time,

$\frac{dV}{dt}=\frac{d}{dt}\left (\frac{4}{3}\pi r^3 \right )\\\\\frac{dV}{dt}=\frac{4}{3}\pi \times 3r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}$

Given that

Radius, r = 24 cm

$\frac{dr}{dt}=0.3cm/s$

Substituting

$\frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi \times 24^2\times 0.3\\\\\frac{dV}{dt}=2171.47cm^3/min$

At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.

The carnival committee has purchased 985 small prizes. The prizes are to be divided equally among the 29 game booths

Vladimir [108]

Answer:

1 The first digit of the quotient is 3

2. 34 prizes per booth

3. 19 prizes left over

Step-by-step explanation:

We need to divide 985 by 29

29 goes into 98 3 times

29*3 = 87 with 13 left over

135 divided by 29

29*4 =116 135-116 =19

985÷29 = 34 with 19 left over
