Since there are 2 nickles and 5 quarters there are 2 nickles for every 5 quarters so answer is 2:5
Answer:
5
Step-by-step explanation:
we can first name the missing term x
3/x=15/25
we can then do some cross multiplication
15x=75
divide both sides by 15
x=5
Therefore the missing term is 5
Answer:
68 feet
Step-by-step explanation:
Vertical motion model:
h = -16t² + vt + s
Given v = 64 and s = 4:
h = -16t² + 64t + 4
This is a parabola. The maximum of a parabola is at the vertex.
For y = ax² + bx + c, the vertex is at x = -b/(2a).
Therefore, the time to reach the maximum height is:
t = -64 / (2 × -16)
t = 2
And the maximum height is:
h = -16(2)² + 64(2) + 4
h = 68
So the Frisbee reaches a maximum height of 68 feet.
Answer:
∠RST = 4x - 6
Step-by-step explanation:
Since SQ bisects ∠RST then
∠RSQ = ∠QST = 2x - 3 and
∠RST = ∠RSQ + ∠QST = 2x - 3 + 2x - 3 = 4x - 6
