Answer:

d=10568.76rads

Step-by-step explanation:

From the question we are told that:

Angular Velocity \omega=580rpm=>60.74rads/sec

Time t=2.9mins=>174sec

Generally the equation for distance d is mathematically given by

 d=\omega*t

 d=60.74*174

 d=10568.76rads

Find an expression equivalent to the one shown below.
TEA [102]

Answer:

  C)  1/6^32

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)^c = a^(b·c)

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

_____

Using these rules, your expression simplifies to ...

  6^8·6^(10(-4)) = 6^8·6^-40 = 6^(8-40) = 6^-32 = 1/6^32

A wildlife shelter is home to birds, mammals, and reptiles. If cat chow is sold in 30 lb bags, what is the least number of bags
kotykmax [81]

Answer:

26 bags

Step-by-step explanation:

A bag of cat chows = 30 lbs

Amount of cat chows needed in a week = 15 lbs = ½ bag of cat chow

There are at least 52 weeks in a year.

The least number of cat chows bags needed at the shelter in 1 year = 52 weeks × ½ bag of chow

= 52 × ½

= 52/2

= 26 bags of cat chow

At least, 26 bags would be needed in 1 year (52 weeks) at this wild life shelter if 15 lbs is consumed weekly.

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers, (k), she can drive with 12
solong [7]
99 km ... 9 liters
x km   ... 12 liters

If the relationship is proportional, we have

\frac{99}{x} = \frac{9}{12}

from where 

x =  \frac{99*12}{9}= \frac{1188}{9}=\bold{132}

The answer is 132 kilometers.
