Herky found that 8 out of every 100 beans in his garden were nibbled by rabbits. How many beans can he expect to be damaged if t
jek_recluse [69]

Answer: 36 beans

Step-by-step explanation:

Make a proportion

For every 100 beans, 8 are damaged

8/100

For every 450 brand, x are damaged

x/450

Set the expressions equal to each other

8/100=x/450

100x=3600

Divide by 100 on both sides

x=36

So, out of 450 beans, 36 should be damaged

Hope this helped! :)

For the function f(x)=2−3x, find f(4).<br><br> A −10<br><br> B −5<br><br> C 12<br><br> D 14
lukranit [14]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

f(x)=2−3x

To find f(4) , substitute the value of x that's 4 into f(x). That is for every x in f(x) replace it with 4.

We have

f(4) = 2 - 3(4)

= 2 - 12

We have the final answer as

<h2>f(4) = - 10</h2>

Hope this helps you
