Answer:
Step-by-step explanation:
In this problem, it is given that,
The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V.
We need to write the direct variation equation for the scenario above. It can be given by :
To remove the constant of proportionality, we put k.
k is any constant
Hence, this is the required solution.
Answer:
Write a ratio.
70 : 5
x : 1
To solve for x, cross multiply.
70 : 5x
Divide both sides by 5.
14 = x

Step-by-step explanation:
let you have an interest in establishing the success of the method be p
as higher the p value ; higher the evidence of method success
hence the p value of 0.001 is preferred because it corresponds to the sample evidence that most strongly supports the alternative hypothesis that the method is effective,
If I'm doing this correctly, you would need to multiply everything inside the parenthesis by 8. So it would be 8x-24y·8x+24y. I'm sorry if that's not right, but that is my interpretation of the problem. Hope I was of some assistance :)
Answer:
Shorter piece is 3 ft, longer piece is 8 ft
Step-by-step explanation:
Set up two equations...
Let x be the length of the shorter piece, and let y be the length of the longer piece.
The whole board is 11 feet long, so
x + y = 11
He wants the longer piece to be 4 feet less than 4 times the length of the shorter board, so
y = 4x - 4
Substitute the second equation into the first equation....
x + 4x - 4 = 11 (y becomes 4x - 4)
Now solve for x
5x = 15 (combine like terms, add 4 to both sides)
x = 3 (divide both sides by 5)
Now substitute 3 in for x in either equation and solve for y...
y = 4(3) - 4
y = 12 - 4
y = 8
