Answer:
divide
7 / 6 = 1 r 6
1 / 6 cannot be done so we multiply by 10
10 / 6 = 1 r 4
4 / 6 cannot be done so we multiply by 10
40 / 6 = 6 r 4 so it is repeating
the answer would be 1.466666666
There is a decimal point because we have to divide the by 10 to cancel it out
Step-by-step explanation:
Answer:
In standard form it is x^4 - 12x^3y + 54x^2y^2 - 108x y^3 + 81y^4.
Step-by-step explanation:
(3y)^4 + 4C1(3y)^3(-x) + 4C2(3y)^2(-x)^2 + 4C3(3y)(-x)^3 + (-x)^4
= 81y^4 - 108y^3x + 54y^2x^2 - 12yx^3 + x^4
Answer:
40 miles per hour
Step-by-step explanation:
Given that:
Distance = 400 miles
Without tailwind :
Time taken = 2.5 hours
Speed = distance / time
Speed = 400 miles / 2. 5
Speed = 160 miles per hour
With tail wind :
Time taken = 2 hours
Net speed = 160 + x
X. = speed of tail wind
Distance = speed * time
400 = (160 + x) * 2
400 = 320 + 2x
400 - 320 = 2x
80 = 2x
x = 40
Speed of tailwind = 40 miles per hour.
