Answer:
1.7 ft
Step-by-step explanation:
We presume you want to find A. And we presume the people are standing shoulder-to-shoulder.
(327,495 mi)/(10^9 persons) = (3.27495×10^5 mi)/(10^9 persons) × (5280 ft/mi)
= 1.7291736×10^9 ft/(10^9 persons)
= 1.7292736 ft/person
≈ 1.7 ft/person
Neither one has eaten a greater amount, because 1/4 and 2/8 are equal to each other. You know this because when you divide the numerator and the denominator of 2/8 by 2, you get 1/4, which is the exact same thing. The only way the amounts would vary is if the size of one candy bar is greater than the other.
Answer:
i think it 5
Step-by-step explanation:
Answer:
x = 55 or x = 15
Step-by-step explanation:
Solve Absolute Value.
We know that either 1/5x - 7 = 4 or 1/5x - 7 = -4.
1/5x - 7 = 4
1/5x - 7 + 7 = 4 + 7
1/5x = 11
1/5x (5) = 11 (5)
x = 55 (one possibility)
1/5x - 7 = -4
1/5x - 7 + 7 = -4 + 7
1/5x = 3
1/5x (5) = 3 (5)
x = 15 (second possibility)
A+b=-7
ab=-15
a=-7-b
b(-7-b)=-15
a=-7-b
-b^2-7b+15=0
a=-7-b
b^2+7b-15=0
a=-7-b
b=(-7±sqrt(109))/2
1)
a=-7-b
b=(-7+sqrt(109))/2
b=(-7+sqrt(109))/2
a=-7+3.5-sqrt(109)/2
b=(-7+sqrt(109))/2
a=-3.5-sqrt(109)/2
2)
a=-7-b
b=(-7-sqrt(109))/2
b=(-7-sqrt(109))/2
a=-7+3.5+sqrt(109)/2
b=(-7-sqrt(109))/2
a=-3.5+sqrt(109)/2
