Answer:
0.13 hours
468 seconds
Step-by-step explanation:
7.8 min= 7.8/60= 0.13 hours
7.8 min= 7.8x60= 468 seconds
Original equation x = yz / a solve for a
xa = yz
a = yz / x
Answer:
Inversely proportion states that a relationship between two variables in which the product is a constant.
If one of the variable increases, then the other decreases in proportion so that the product is unchanged.
If y is inversely proportional to x, then the equation is of the form
; where k is the constant proportionality.
As per the given condition: Speed of a car is inversely proportional to the time it takes to complete a 100 mile trip,
Let x represents the speed of car and y represents the time taken.
From the given condition:

Then by definition of inversely proportional;
[Since,
]
Here, k represents the distance(i.e constant) = 100 miles.
therefore, the equation becomes now;
or
xy = 100
The following graph for the above equation as shown below :
Answer:
hello
Step-by-step explanation:
Answer:
≈ 10.20
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(7, - 3) and (x₂, y₂ ) = B(9, 7)
d = 
= 
=
=
≈ 10.20 ( to 2 dec. places )
