3/10 divided by 4/5 ... Divided then put into simplest form

1 answer:

5 0

The operation 3 / 10 ÷ 4/ 5, can also be written as (3 / 10) x (4 / 5). The operation can be done by multiplying the numerators and denominators which is equal to 12 / 50. This may be further simplified as 6/25.

The fish population of Lake Collins is decreasing at a rate of 5% per year. In 2004 there were about 1,350 fish. Write an expone

ad-work [718]

Answer:

Part 1) The exponential function is equal to $y=1,350(0.95)^{x}$

Part 2) The population in 2010 was $992\ fish$

Step-by-step explanation:

Part 1) Write an exponential decay function that models this situation

we know that

In this problem we have a exponential function of the form

$y=a(b)^{x}$

where

y ----> the fish population of Lake Collins since 2004

x ----> the time in years

a is the initial value

b is the base

we have

$a=1,350\ fish$

$b=(100\%-5\%)=95\%=0.95$

substitute

$y=1,350(0.95)^{x}$ ----> exponential function that represent this scenario

Part 2) Find the population in 2010

we have

$y=1,350(0.95)^{x}$

For $x=(2010-2004)=6\ years$

substitute

$y=1,350(0.95)^{6}=992\ fish$

Answer: Total old car is $2955.89, new car $1080.94 *for 3yrs

Step-by-step explanation:

Old= [(100/19)($2.36)(52)+$770]*3 = $2955.89

New=[(100/34)($2.36)(52)+20(12)]*3= $1080.94
