Answer: temperature and weight
Step-by-step explanation: Temperature can increase or decrease/can go up and down without moving. The same goes with weight, it can go up or down without moving.
Remark
Don't try and do this all at once. Break it down, otherwise you'll have layers and brackets all over the place.
Step One
Find 23/0.3
X = 23/0.3 = 76.7
Step Two
Now Divide by 20
x1 = 76.7 / 20
x1 = 3.83
Step Three
Take this result and put it over 24
x2 = x1/24
x2 = 3.83 / 24
x2 = 0.1597 <<<< Answer
Answer: 90%
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is inversely proportional to x² then the equation relating them is
y =
← k is the constant of variation
To find k use any ordered pair from the table.
Using (1, 4 ) , then
4 =
=
( multiply both sides by 1
4 = k
y =
← equation of variation
(b)
When y = 25 , then
25 =
( multiply both sides by x² )
25x² = 4 ( divide both sides by 25 )
x² =
( take the square root of both sides )
x = ±
= ± 
Since x > 0 then x =
