The answer would be 10 because anything under 4 rounds down (including 4 itself, unlike 5, which rounds up.
Answer:
34.22 liters
Step-by-step explanation:
Step one:
Given data
A car averages 28.5 miles per gallon of gasoline
How many liters of gasoline will be needed for a trip of 415 km
let us convert 415km to miles first
1 km is 0.621371 miles
415km is x miles
cross multiply we have
x= 415*0.621371
x=257.86 miles
Step two:
if 1 gallon of gasoline will cover 28.5 miles
the x gallons will cover 257.86 miles
cross multiply we have
28.5x= 257.86
divide both sides by 28.5
x= 257.86/28.5
x=9.04 gallons
Step three:
let us convert gallons to liters
1 gallon is 3.78541 liters
9.04 gallons will be x liters
cross multiply we have
x=9.04*3.78541
x= 34.22 liters
Answer:
5 for each team, 2 left over
No, because only a minority of the students answered it.
Step-by-step explanation:
Parametric equations of the line, 9x + y = -1
Assign any one of the variables equal to s. (say x = s).
By substituting the value x=s in the given equation,
The equation can be rewritten as 9s + y= -1
Set of parametric equations is x = s and
y= -9s- 1 (or) y= -(9s + 1)
