Answer:
There are 59,049 different ways of answering the exam.
Step-by-step explanation:
The first thing we need to count is the total number of selections, then we need to count the number of options for each one of these selections. The total number of combinations will be equal to the product between all the numbers of options.
Here, the selections are each one of the 10 questions, so we have 10 selections.
And each one of these selections has 3 options (true, false, blank)
So, we have 10 selections with 3 options each, then the total number of combinations will be:
C = 3*3*3*3*3*3*3*3*3*3 = 3^10
C = 59,049

Answer:
42 cm ^2
Step-by-step explanation:
The area of a triangle is 1/2 B x H ( one half base times height)
The base is 6 cm and the height is 14 cm. So the full equation now is
1/2 (6) (14)
First you multiple 6 times 14 which is 84. Next you just divide it by 2 because 1/2 is half of the number. 84 divided by 2 is 42. So your answer is
42 cm ^2 (centimetres squared)
