Answer:
100 children
150 adults
Step-by-step explanation:
c- children
a- adults
---------------
we get equations as per question:
- 1.5c+4a= 750
- c+a= 250 ⇒ a= 250- c
- 1.5c +4(250-c)= 750 ⇒
- 1.5c- 4c+1000=750 ⇒
- 2.5 c= 250 ⇒
- c= 100
- a= 250-100 ⇒
- a= 150
Children 100, adults 150
Answer:
The answer is "The second choice".
Step-by-step explanation:

Formula:


Recall that the diagonals of a rectangle bisect each other and are congruent, therefore:

Substituting the given expression for each segment in the first equation, we get:

Solving the above equation for x, we get:

Substituting x=10 in the equation for segment EI, we get:

Therefore:

Now, to determine the measure of angle IEH, we notice that:

therefore,

Using the facts that the triangles are right triangles and that the interior angles of a triangle add up to 180° we get:
