At the begining of 6 grade the ratio of number of the advanced math students to the number of regular students was 3:8. However after taking the placement tests students were moved around changing the ratio of the number of advanced msth students to the number of regulsr math students to 4:7. How many students started in regular math and advanced math if there were 92 students in advanced math after placement?

Answers

Answer 1

Answer: The total students were 253.

D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. What is m∠DEF?

Answers

Answer:

m∠DEF is 90°

Step-by-step explanation:

It is given that D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. Thus, using the distance formula, we have

⇒

and

⇒

Also,

⇒

Now,

⇒

Thus, Pythagoras theorem holds.

Hence, m∠DEF is 90°⇒ΔDEF is right angled triangle which is right angled at E.

DE^2 = 1 + 16 = 17.

EF^2 = 16 + 1 = 17.

DF^2 = 9 + 25 = 34.

Since (DE)^2 + (EF)^2 = (DF)^2,

angle E is 90 degrees.

DF must be the hypotenuse

Here look at that

Antonia is keeping track of the number of pages she reads. She started the school year having already read 95 pages her book, and she then reads 20 pages each day. The function for her total pages read is f(x) = 20x + 95. What do f(x) and x represent in Antonia's situation?1. f(x) represents the number of days; x represents the total number of pages that Antonia has read
2. f(x) represents the total number of pages that Antonia has read; x represents the number of days
3. f(x) represents the number of pages Antonia reads per day; x represents the number of days
4. f(x) represents the total number of pages that Antonia has read; x represents the number of pages she reads per day

Answers

20 pages per day
so the variable attached to the number 20 would be "number of days"
so x represents the number of days

then 90 + 20(number of days) = (total number of pages)
so that makes f(x) = (total number of pages)

therefore your answer is 2.

Answer:

Option 2. f(x) represents the total number of pages that Antonia has read; x represents the number of days
