We are given certain rule to identify number. We have to identify from the entries that can be interpreted as numbers.

a) 1.56e-9

This a number as there are no spaces, no comma, no units.

b) -4.99

This a number as there are no spaces, no comma, no units.

c) 40O0

This is not a number as 0 is substituted by O.

d) 1.9435

This a number as there are no spaces, no comma, no units.

e) 1.56 e-9

This is not a number as it contains a space.

f) $2.59

This is not a number as it contains a dollar sign.

g) 3.25E4

This is not a number as it contains alphabet.

h) 5,000

This is not a number as there is a comma in the given.

In the United States, 13 out of every 20 cans are recycled.What percent of cans are recycled?

Alex_Xolod [135]

65% (N=what percentage) because 13 over 20 divided by n over 100 = 20n = 13(100) = 20n=1300 and then to divide, 20n / 20 = 1300 / 20 = n= 65 or 65%

A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decr

Elena L [17]

Answer:

$0.0727 cm\: per\: second$

Step-by-step explanation:

The Volume of the cylinder is constant

Volume of a cylinder, $V=\pi r^2h$

Given:

$\frac{dh}{dt}=0.8 cm/sec\\ r=2cm\\h=11cm\\\frac{dr}{dt}=?$

$\frac{dV}{dt}=\pi r^2 \frac{dh}{dt} + 2\pi r h\frac{dr}{dt}$

$0=\pi* 2^2*0.8 + 2\pi*2*11\frac{dr}{dt}\\0=3.2\pi+44\pi\frac{dr}{dt}\\44\pi\frac{dr}{dt}=-3.2\pi\\\frac{dr}{dt}=\frac{-3.2\pi}{44\pi} \\\frac{dr}{dt}=-0.0727 cm\: per\: second$

The radius is decreasing at a rate of $0.0727 cm\: per\: second$
