Answer: The required value of f(x) for x = 1 is 11.

Step-by-step explanation: We are given to evaluate f(x) for x = 1, where

$f(x)=3x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To evaluate the required value, we need to substitute x = 1 in expression (i).

So, putting x = 1 in (i), we get

$f(1)=3\times1+8=3+8=11.$

Thus, the required value of f(x) for x = 1 is 11.

Answer:

105% ?

Step-by-step explanation:

I'm not entirely sure if the 1 yard 'squared' is considered in the 30% but assuming it's not ... 1yd =30% 1yd^2=60% and 2yd=45% so 60%+45%=100%

In an upcoming race, the top 3 finishers will be recognized with the same award. There are 12 people entered in the race.

Answer:

220

Step-by-step explanation:

Given,

The total number of people = 12,

Out of which, top 3 finishers will be recognized with the same award,

So, the total possible way = total combination of 3 people out of 12 people

$=^{12}C_3$

$=\frac{12!}{3!(12-3)!}$

$=\frac{12\times 11\times 10\times 9!}{3\times 2\times 9!}$

$=\frac{1320}{6}$

$=220$

Hence, there are 220 ways the top 3 racers can be grouped from the 12 people.
