1. 3 blues, 2 red, 1 pink.
2.3 blues, 2 pink, 1 red.
3. 4 blues, 1 red, 1 pink
All these three ways follows the rules that; there must be three colors an also Blue sections are more than red sections or pink sections.
It will take the first horse 2.5 hours to run a mil
It will take the second horse 4 hours to run a mil
Find the required graph attached.
The formula for calculating speed is expressed as:
Get the speed of each horse
Speed for the first horse = 5/2 = 2.5 miles/hr
Time = 2.5 * 1
Time = 2.5 hours
Hence it will take the first horse 2.5 hours to run a mile
Speed for the second horse = 4/1 = 4 miles/hr
Time = 4 * 1
Time = 4 hours
Hence it will take the second horse 4 hours to run a mile

Answer:
2A/h - b =a
Step-by-step explanation:
A=h(a+b)/2
Multiply each side by 2
2A =h(a+b)/2*2
2A=h(a+b)
Divide each side by n
2A/h = h(a+b)/h
2A/h = a+b
Subtract b from each side
2A/h - b =a+b-b
2A/h - b =a
Answer:
((2A)/h)- b=a
Step-by-step explanation:
First get the 2 to the left by multiplying each side by 2. Then, get h to the right by dividing each side by h. Lastly, subtract b from each side.
Enter your answer as a fraction in simplest form in the box.
y = x
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
Substitute the values and solve for k
therefore
the equation of the line is equal to
Answer:
Step-by-step explanation:
Direct proportionality states:
if
then, the equation is in the form of:
......[1] where, k is the constant of proportionality.
As per the statement:
The graph of a proportional relationship contains the point (20, 4).
Substitute these point in [1] we have;
Divide both sides by 20 we have;
or
Therefore, the corresponding equation is:
