The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
d
=
12.5
×
t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y
=
k
x
where
y
and
x
are the related quantities and
k
is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)
Answer:
Multiply both sides of the equation by -2
Distribute -1/2 over (x+4)
Step-by-step explanation:
we have
<em>Method 1</em>
Multiply both sides of the equation by -2 ------> <em>Step 1</em>
Subtract 4 from both sides of the equation
<em>Method 2</em>
Distribute -1/2 over (x+4)-------> <em>Step 1</em>
Multiply both sides of the equation by -2
Subtract 4 from both sides of the equation
Answer:
Irrational
Step-by-step explanation:
2.060060006... never ends, thus it is an irrational number
an irrational number is a number that can not be expressed by a fraction of two integers
you can tell it never ends because of the addition of ... at the end of the number
Answer:
2916
Step-by-step explanation:
1.5 feet is 1 foot 6 inches, or 18 inches
volume is height * length * width, so 18 * 9 * 18 = 2916
