Given that DF/PR=FE/RQ=3/2, what additional information is needed to prove △DEF ~ △PQR using the SSS similarity theorem?A. DE ≅ PQ
B.C. DE/EF = 3/2
D. DE/PQ = 3/2

Answers

Answer:

Option D.

Step-by-step explanation:

Given information: $(DF)/(PR)=(FE)/(RQ)=(3)/(2)$ .

We need to find the additional information which is needed to prove △DEF ~ △PQR using the SSS similarity theorem.

According to the SSS similarity theorem, two triangles are similar if their corresponding sides are proportional.

Using SSS similarity theorem, both △DEF and △PQR are similar if

$(DE)/(PQ)=(E F)/(Q R)=(DF)/(PR)$

If can be written as

$(DE)/(PQ)=(FE)/(RQ)=(DF)/(PR)$

It is given that $(DF)/(PR)=(FE)/(RQ)=(3)/(2)$ .

So, the additional information which is needed to prove △DEF ~ △PQR using the SSS similarity theorem is $(DE)/(PQ)=(3)/(2)$ .

Therefore, the correct option is D.

The number 450 is increased by 75%. The result is then decreased by 90%. What is the final number?

Answers

Answer:

The final number is 78.75

Step-by-step explanation:

we know that

1) The number 450 is increased by 75%

The number 450 represent 100%

Remember that

$100\%+75\%=175\%=175/100=1.75$

The increased number is

$450(1.75)=787.5$

2) The result is then decreased by 90%

In this moment

787.5 represent the 100%

Remember that

$100\%-90\%=10\%=10/100=0.10$

The decreased number is

$787.5(0.10)= 78.75$

therefore

The final number is 78.75
