Answer: A = 16 and B = 28
Explanation:
16 + 28 = 44
16:28 = 4:7
:)
I don't think either is right
I think it should be
44-7=x
So 44 - 7 = 37
X =37
Answer:

Step-by-step explanation:
Answer: $66.7
Step-by-step explanation:
Answer:The equation for inverse proportion is calculated as xy=k.
When 20 people attend the picnic, the cost for each person was $50, then k will be= 20 × 50 = 1000
Recall that k = xy
For the second aspect of the question, x= 15, k= 1000.
k= xy
y = k/x
= 1000/15
= 66.7
If 15 people attend the picnic instead, the cost per person will be $66.7
Answer:
Step-by-step explanation:
Let the distance be 
and the time be 
.
It was given that the distance, , varies directly as the square of the time , we write the proportional relation,
.
, where 
is the constant of variation.
It was also given that, 
, when 
.
Now the equation of variation becomes;
When, 
, 
The object will travel 301865 feet in 55 seconds.
