Answer: 44 boys and 40 girls
Step-by-step explanation:
x = number of girls
x + 4 = number of boys
x + x + 4 = 84
2x + 4 = 84
2x = 80
x = 40
84 - 40 = 44
The correct answer is B C and D

Answer:
x = 8√5
Step-by-step explanation:
In the figure attached, there are three right angle triangles.
So, by Pythagoras theorem,
y²+ 4² = z²
y² + 16 = z²------(1)
Similarly x² = 16² + y²--------(2)
and (16 + 4)² = x² + z²
20² = x² + z²-------(3)
Now we put the value of z² from equation 1 to equation 3
20² = x² + y² + 16
x² + y² = 400 - 16
x² + y² = 384
y² = 384 - x²------(4)
Now we put the value of y² from equation 4 to equation 2
x² = 16² + 384 - x²
2x² = 256 + 384
2x² = 640
x² = 320
x = 8√5
Therefore x = 8√5 will be the answer.
Answer:
P=3T-50
Step-by-step explanation:
Form the given four values we can assume a linear relationship between profit and the no of tickets sold.
Let the equation corresponding to that be some P=aT+b.
Now substitute the first set of values(100,50) in the above equation we get
100=50a+b.
Now substituting second set of values (100,250) we get 250=100a+b.
Let these equations be eq1 and eq2.
Now substract eq1 from eq2 we get 50a=150 or a=3.
Substitite value of a in one of the equations we get b=-50.
∴P=3T-50
