blsea [12.9K]

Solution would be <span>30. By dividing 100 by 25 you realize that for every pound of ground beef you get 1 hamburger, in other words, 1/4 the number of burgers is the amount of ground beef. So what's 1/4 of 120 the answer should be 30.

The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in

Answer:

$\frac{dD}{dt}= 181\frac{168}{1600}$

Step-by-step explanation:

h= 1000 ft

dx/dt= 232 ft/sec

D= 1600 ft

First, we have to find a distance x ( shown in the figure)

applying pythagorus theorem

D^2= h^2+x^2................1

x^2= D^2-h^2

= 1600^2-1000^2

x^2= 1560000

x=1248.99 m

Now we can find out how fast the aircraft is receding from the trawler

( notice that the height is not changing)

so differentiating equation 1 w.r.t t we get

$\frac{d}{dt} (D^2)= \frac{d}{dt}(h^2+x^2)$

2DD'= 2hh'+2xx'

$D\frac{dD}{dt}= h\frac{dh}{dt}+x\frac{dx}{dt}$

now putting values we get

$1600\frac{dD}{dt}= 1000\times0+232\times1249$

$\frac{dD}{dt}= 181\frac{168}{1600}$

Answer:

D

Step-by-step explanation:

Count the number of places it takes to get one place past 3

There are 5 zeros in the given question. That gets you to just before the 3.

Add one more to get past the 3. That makes 5 zeros + 1 more place = 6

Since you are moving right, the 6 is minus. Your answer is 3 * 10^-6
