7/8 and 3/4
Both need to have same denominator so it would be 32, in this case because 8*4 is 32.
7/32+3/32=10/32 simplified to 5/16
Answer:
Student ticket cost $11
Adult ticket cost $12
Step-by-step explanation:
Let number of student ticket be x and adult ticket be y
3x+3y=69
5x+3y=91
Subtract above equation you get
-2x=-22
x=11
Since 3x+3y=69 will
x+y=23 by dividing throughout by 3
y=12
Answer:
46.57
Step-by-step explanation:
Given that:
h(t) = 37t - 4.9t²
When the ball reaches the ground, then the height is zero;
So, we equate h(t) to zero and solve for t
37t - 4.9t² = 0
t = 0, 7.55
Let the Initial time be a = t = 0
The time the ball reaches the ground be b = 7.55
So, the average height can now be calculated as:
Average height =
=
=
=
= 46.57091665
≅ 46.57 to (2 decimal places)
