Find the length of a fence that surrounds a square garden if the length of one side of the garden is given. Are the length of th

e fence and the length of one side directly proportional quantities? Explain

Answer:

A square has 4 sides with equal length.

So the perimeter of a square is equal to 4 times the length of one side.

Now, suppose that we know that the length of one side of the garden is x.

Then the total length of the fence that surrounds the square is:

L = 4*x.

Now let's define proportional quantities:

x and y are proportional quantities if:

x = k*y

where k is a constant of proportionality.

In the case of our problem, we have a relation between L (total length of the fence) and x (length of one side of the garden)

L = 4*x

This is a proportional relation, and 4 is the constant of proportionality.

Write the point slope form of the given line that passes through points (-4,-1) and (3,-3). Identify (x1,y1) as (-4,-1) include
Masteriza [31]
Y-y1=m(x-x1)

find slope
(y2-y1)/(x2-x1)

so
(-4,-1)
(3,-3)
slope=(-3-(-1))/(3-(-4))=(-3+1)/(3+4)=-2/7

y-(-1)=-2/7(x-(-4))
y+1=-2/7(x+4)

Given m∠JML = 80 and m∠KML = 33, what is m∠JMK
Harrizon [31]

Answer:

<h2>47°</h2>

Step-by-step explanation:

Given m∠JML = 80 and m∠KML = 33, to calculate the value of angle m∠JMK, we will apply the formula since all the angles are all acting at point M.

m∠JML = m∠JMK+m∠KML

Substituting the values given into the equation;

80 = m∠JMK + 33

subtract 33 from both sides of the equation

m∠JMK = 80-33

m∠JMK = 47°

<em>Hence the value of angle m∠JMK is 47°</em>
