Answer:
25 + 15n ≥ 150
Step-by-step explanation:
The term at least mean the amount saved is greater than or equal to 150
Let the number of weeks he intends to save be n
Amount saved after n weeks without the plan is:
15n
Add plan amount
= 25 + 15n
Add inequality
25 + 15n ≥ 150
Answer:
y = - 
x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 24, y = - 6
- 6 = 24k ( divide both sides by 24 )
= k , that is
k = -
y = - x ← equation of variation
To convert m/s to mi/min we have to find conversion factor first
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let’s put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min
Answer: V = 1.118 ∙ 107 mi/min
