In triangle DEF, the length of DE is √••30 inches, and the length of EF is 3 inches. If it can be determined, what is the length, in inches, of DF ? F. 3 G. √••30 H. √••33 J. √••39 K. Cannot be determined from the given information

The value of DF cannot be determined due to insufficient information. Option D is correct.

Given information:

In triangle DEF, the length of DE is inches, and the length of EF is 3 inches.

It is required to find the length of DF.

Now, the information is insufficient because the type of triangle is not given, and neither the angles are given.

If the triangle is a right triangle, then the third side can be easily found using the Pythagoras theorem. Also, if we know the value of angles, then using the sine or cosine rule, we can calculate the third side.

But based on the given information, the third side cannot be found.

Therefore, the value of DF cannot be determined due to insufficient information. Option D is correct.

K. Cannot be determined from the given information.

Step-by-step explanation:

In the given triangle DEF, DE=√30 Inches, and EF=3 Inches. The length of DF cannot be determined from the given information.

We can only solve for DF if either an angle is given or the type of triangle is specified.

If an angle is given, we can use Sine or Cosine Rule to find the length as appropriate.

If the triangle is a right triangle, we can use Pythagoras Theorem.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.
