Answer:
7/10 hours
Step-by-step explanation:
her first assignment took 1/2 hour
her second assignment took 1/5 hour
so in total she took 1/2 + 1/5
we need to find a common denominator
the lcm(2,5)=10
so multiply 1/2 by 5/5 to obtain 5/10
multiply 1/5 by 2/2 to obtain 2/10
5/10 + 2/10 = 7/10
1 and .20 can be your answer i guess.

Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
