Answer:
a
Step-by-step explanation:
4X2 is 8 8x2 is 16 16x2 is 32
To find the difference, we need to subtract the height of the fish from the height of the bird. If we use sea level as 0, then the bird flies at 1,281 feet, and the fish swims at -282 feet.
1,281 - (-282) = <span>1,281 + 282 = 1,563 feet
There is a </span><span>1,563 feet difference between the height of the bird and the depth of the fish</span>
The number ... n
one quarter of the number ... 1/4 of n = 1/4 * n
one third of the number ... 1/3 of n = 1/3 * n
one quarter of the number is subtracted from one third of the number ... 1/3 * n - 1/4 * n
the result is 7 ... = 7
We can put it together:
1/3 * n - 1/4 * n = 7
4/12 * n - 3/12 * n = 7
1/12 * n = 7 /*12
n = 7 * 12
n = 84
The number you are looking for is 84.
F is proportional to 1/x^2
distance = x
A reduction of 25 percent = 0.75x
Let’s put this in place of x
F = 1/(0.75x)^2
And simplify
F = 1/0.5625x^2
So you need to find the percentage increase from 1/x^2 to 1/0.5625x^2
So what does 1/x^2 multiply by to give 1/0.5625x^2
Written as an equation it is y/x^2 = 1/0.5625x^2
Multiply both sides by x^2
y = 1/0.5625
y = 1.778 (rounded to 3 decimal points)
So the decimal multiplier is 1.778 and so the percent increase is approximately 77.8%
Answer:
As per the statement: the value of the expression 7 x n/4 greater than 7.
To describe the relationship between n and 4.
"greater than" symbol is represented by '>'
The value of expression 
grater than 7 is;
Divide by 7 both sides we get;
Multiply both sides of an equation by 4 we get;
Therefore, the relationship between n and 4 is,
