Total tickets sold = 800
Total revenue = $3775
Ticket costs:
$3 per child,
$8 per adult,
$5 per senior citizen.
Of those who bought tickets, let
x = number of children
y = number of adults
z = senior citizens
Therefore
x + y + z = 800 (1)
3x + 8y + 5z = 3775 (2)
Twice as many children's tickets were sold as adults. Therefore
x = 2y (3)
Substitute (3) into (1) and (2).
2y + y + z = 800, or
3y + z = 800, or
z = 800 - 3y (4)
3(2y) + 8y + 5z = 3775, or
14y + 5z = 3775 (5)
Substtute (4) nto (5).
14y + 5(800 - 3y) = 3775
-y = -225
y = 225
From (4), obtain
z = 800 - 3y = 125
From (3), obtain
x = 2y = 450
Answer:
The number of tickets sold was:
450 children,
225 adults,
125 senior citizens.
Answer:
12
Step-by-step explanation:
Given
with reference angle 45°
hypotenuse (h) = x
perpendicular (p) = 6√2
Now
with reference angle 45°
sin 45° = p / h
1 / √2 = 6√2 / x
Cross multiply ✖
6√2 * √2 = x
x = 6 * 2
x = 12
Answer:
Three out of six chance
Step-by-step explanation:
There is a three out of six chance because they don’t have six numbers and three of them aren’t even so that will make it a three out of six chance. The probability of the dice landed on a one is a one out of six chance because there is only one of the number ones. I hope that’s helpful
Hi!
a: <em>F </em><em>n </em><em>G </em>=(Intersection) {4,6,8,10}
b: <em>F </em><em>n </em><em>H </em>={empty set}
Because there is no common element between the elements of set F and the elements of set H.
Note: It may not be very clear as I don't speak English.
God work!
