Jill got an 85% on a math test if there were 40 questions in total,how many did she get wrong?

Answers

Answer 1

Answer: You can solve this by setting up a proportion. You can put the number of items correct over the total number. and substitute the unknown number with x.

$(85)/(100)$ = $(x)/(40)$ Cross-multiply
3400 = 100x Divide both sides by 100
34 = x

40 - 34 = 6

So, Jill got 6 questions wrong.

Answer 2

Answer: yeah she got 6 questions wrong

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.
