Nuetrik [128]

Answer

There are 170 ways the student can answer the test.

Explanation

If there are 20 multiple-choice questions with 5 choices each, the student has 100 choices. The first question has 5 choices to pick from. The second has 5 as well. So does the third. Hopefully now you realize that you have to multiply the number of choices by the number of questions.

The same thing goes with the true/false questions. There are 2 choices for each true/false question, and there are 35 of those. 35×2 is 70. There are 70 ways to answer on the true/false questions.

Now combine the number of choices on the first part and the second part; 100+70 is 170.

Ronch [10]
The perimeter = 2 length + 2 width 

the length = the width +47

314 = 2*(w+47) +2w

314 = 2w +94 +2w

220 =4w

w= 220/4 = 55

l = 55+47 = 102

the length = 102 ft

the width = 55 ft
