Answer:
EF = 6.6
Step-by-step explanation:
Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.
Answer:
The student scores 20 pts
Step-by-step explanation:
A student answers 10 Q's correct, this earns the student 30 points (3 x 10)
The other 5 Q's are presumably wrong since they did answer the question
If every question wrong loses 2 pts then the student lost 10 points from wrong answers (2x5) =10
Take the total amount of secured points and subtract the points for questions that the student got wrong
30 pts - 10 pts = 20 pts

Answer:
3.75 cm
Step-by-step explanation:
Corresponding sides are proportional.
CD/BC = BC/AB
CD = (BC)²/AB . . . . . multiply by BC
CD = (6 cm)²/(9.6 cm) = (36/9.6) cm
CD = 3.75 cm
