To find a mixed number from a decimal u basically just keep the whole number and put everything to the right of the decimal point as the numerator. the denominator is just a 1 with however many digits there are. for example, 4.216 would be 4 216/1000. from there, u just simplify it :)

4.4 .
there is 5280 feet per mile. Meaning there is 15840 feet in three miles. Divide 15840 feet by 60(number of minutes in an hour and you get 264 , which is how many feet per minute. Divide 264 by 60(number of seconds in a minute) and you get 4.4, the number of feet per second

In a relay race, the probability of the galaxy team winning is 22%. in another unrelated relay race, the probability of the kome

lina2011 [118]

We know that
the probability of the Galaxy team winning is 22%------> 0.22
the probability of the Galaxy team losing is 100%-22%----> 78%-----> 0.78

the probability of the Komets team winning is 47%------> 0.47
the probability of the Komets team losing is 100%-47%----> 53%-----> 0.53

therefore
the probability of the comets losing their race and the galaxy winning theirs is
0.53*0.22=0.1166------> 11.66%

the answer is
11.66%

Anni [7]

Answer:

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.

Step-by-step explanation:

We are given the following information in the question:

A spherical balloon is designed to pop at the instant its radius has reached 3 centimeters.

The balloon is filled with helium at a rate of 10 cubic centimeters per second .

$\displaystyle\frac{dV}{dt} = 10~cm^3/sec.$

We have to find fast the radius is growing at the instant it pops.

Volume of spherical balloons =

$\displaystyle\frac{4}{3}\pi r^3$

Differentiating, we get,

$\displaystyle\frac{dV}{dt} = \frac{4}{3}\pi 3r^2 \displaystyle\frac{dr}{dt} = 4\pi r^2 \displaystyle\frac{dr}{dt}$

Putting the values, we get,

$10 = 4\times 3.14\times (3)^2\times \displaystyle\frac{dr}{dt}\\\\\frac{dr}{dt} = \frac{10}{4\times 3.14\times (3)^2} = 0.0884 \approx 0.09\\\\\frac{dr}{dt} = 0.09\text{ centimeter per second}$

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.
