Amathematics competition consists of 30 multiple-choice questions. a
correct answer is awarded 4 marks while 1 mark is deducted for a wrong
answer. no marks will be awarded or deducted for questions not attempted.
a student skipped 3 questions and had a score of more than 44. find the
minimum number of correct answers obtained.

16

Step-by-step explanation:

let "x" be the number of correct questions and 37-x be the wrong questions,

4x-1(37-x)=44

4x-37+x=44

5x=81

x=16.2

hence,16 is the answer

420

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
