Answer:
Step-by-step explanation:
2⅝ miles/(3½ minutes) = (21/8 miles)/(7/2 minutes) = ¾ mile/minute
d = ¾m = 0.75m
To solve for the time an object takes to hit the ground, the equation
<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>
(-2*60/-9.8)^½ = 3.50 seconds.

Answer:
Step-by-step explanation:
A) 5x = 3(x - 2.5)
-----------------------
B)
Distribute
5x = 3x - 7.5
Subtract 3x from both sides
2x = -7.5
Divde both sides by 2
x = -3.75
-----------------------
C)
5 * (-3.75) = 3(-3.75 - 2.5)
-18.75 = -18.75
D)
Tanya paid –$3.75 for each of 5 items
Tony paid –$6.25 for each of 3 items
There seems to be an error in the question since the cost of items is negative
Tony bought fewer items and paid less for each.
Answer:
Almond , raisins:
(1, 15)
(3, 7.5)
(5, 0)
Step-by-step explanation:
x: almond
y: raisin
30x + 8y = 150
x = 1, y = 15
x = 3 y = 7.5
x = 5, y = 0
