Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
Answer: there you go

The constant of proportionality in terms of the cost per text is the coefficient of

in the equation

. Since the coefficient of

is 0.25, the constant of proportionality in terms of the cost per text is 0.25.
Proportionality constants are usually expressed as fractions, so lets convert 0.25 to a fraction. To do that we are going to add the denominator 1 to our decimal, and then we will multiply both numerator and denominator by ten for every number after the decimal point:


Finally, we can simplify our fraction:

We can conclude that the constant of proportionality in text of the cost per text is
1/4
Answer:
<em>f(x) = 1/2x + 4</em>
Step-by-step explanation:
The rise of the function is 1 and the run is 2, so our slope is .5 or 1/2!
The function crosses the y-intercept at point (0,4) so our b value is positive 4!
