Naomi has been contracted to put decorative lights on the outside edges of a building. she knows that each string of lights she will use has a length of 47 feet. if the outside edges of the building total 1350 feet what is the least number of strings of light naomi need?
a)26
b)27
c)28
d)29
x

You would divide 1350 by 47 to find our how many strings of lights she would need.

1350 / 47 = 28.7234

note that IF you choose 28, you would run short because it would not be enough to cover all of that edge.

so you would need to round up to 29

therefore our answer would be D)29 strings of lights.

y= -1x + 8

Step-by-step explanation:

so we have to know that the side of Triangle DEF that is parallel segment BC is  EF.  

we know that the side EF contains the coordinates (4,4) and (6,2).

So we could use this to find the slope for side EF by finding the difference in the y values and dividing it by the difference in the x values.

4-2= 2

4-6= -2

2/-2= -1  so the slope is negative one.

Now we have to find the y-intercept so we could plot in the x  and y values and the slope into the equation    y=mx + b to find the y-intercept.

In the coordinates (6,2)  6 is the x value and 2 is the y value.

so we put it like this   2=-1(6) + B where -1 is the slope.

2= -6 + b  add 6 to both sides and  b= 8.

so now we know the slope and the y-intercept so we will write the equation like this.    y= -1x + 8
