Answer:
21
Step-by-step explanation:
Use Pemdas.
Parentesis first so 5+4 = 9 and 8-6=2 so, 9X2=18+3=21
I think its 40 over 81, 40/81
We know the total tickets sold = 400.
Let x be the number of adult tickets sold.
That means 400 - x is the number of student tickets.
The revenue from adult tickets will be $3 * x, which we can call 3x.
The revenue from student ticks will be $2 * (400 - x), or 800 - 2x.
The total revenue is $1050, so that means:
3x + (800 - 2x) = 1050.
Removing the parentheses:
3x + 800 - 2x = 1050
Subtracting 800 from both sides:
3x - 2x = 250
Simplifying the left side:
x = 250, which is the number of adult tickets.
400-x = student tickets = 400-250 = 150.
ALWAYS check!
In this case, check the revenue:
3x = 3(250) = 750
2(150) = 300
750 + 300 = 1050. Check!
Answer:
in my opinon, this table is proportional
The height of the cone is 4 cm (approx).
Step-by-step explanation:
Given,
The radius (r) of the cone = 4.96 cm
Volume (V) = 102 cm³
To find the height (h) of the cone.
Formula
The volume of a cone V = 
πr²h
Now,
According to the problem,
πr²h = 102
or, ×
×(4.96)²h= 102
or, h = 
or, h = 3.95 = 4 (approx)
so,
Height = 4 cm (approx)
