Answer:
Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 = = C * 1 = C
then

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as
6 people - $9.75,
24 people - $x.
Or as proportion,
Find x:
Answer: It would cost $39 to serve 24 people
Answer:
a = 64
Step-by-step explanation:
The geometric mean of 2 numbers a and b is , then
= 16
( square both sides )
28a = (16 )² = 1792 ( divide both sides by 28 )
a = 64
Answer:
Step-by-step explanation:
→ First understand what Pythagoras theorem is
Pythagoras is a theorem used to find the hypotenuse (the side opposite to the right-angle) of a triangle. We would need the base lengths as well the height in order to use Pythagoras.
→ State the formula and identify the letters
a² + b² = c² ⇒ where 'a' is 380cm, 'b' is 290cm and 'c' is what we are trying to work out
→ Substitute in the values into the formula
380² + 290² = c²
⇒ Simplify
144400 + 84100 = c²
⇒ Collect the numbers together
228500 = c²
⇒ Square root both sides to find 'c'
478.0167361 = c
→ The length of the diagonal is 478.02
