Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
Answer:
Square root of 65 or 8.06 to the nearest hundredth.
Step-by-step explanation:
We use the Pythagoras Theorem ( Distance Formula):
This = √ [( x2 - x1)^2 + (y2 - y1)^2 ]
= √ [( 3 - -4)^2 + (-1 - -5)^2]
= √ (7^2 + 4^2)
= √65
= 8.06 to the nearest hundredth.
Answer:
3
Step-by-step explanation:
1/2 is 3 times 1/6, because 3/1
and 3/6 is the same as 1/2. Thus, he can make 3 bowls of granola.
