Estimate the total percentage of complaints about parking difficulties and the location of the store. (nearest whole percent)
AysviL [449]

Answer:

Therefore the total  Complains about parking difficulties=32.26%

Therefore the total  Complains about the location of the store=25.81%

Step-by-step explanation:

Given ,

Complains about difficulty parking = 250

Complains about isolated location = 200

Complains about ruled sales clerks=150

Complains about too expensive=125

Complains about confusing layout= 50

Total complains = (250+200+150+125+50)

                          =775

Therefore the total  Complains about parking difficulties

=\frac{250}{775}\times 100 %

=32.26%

Therefore the total  Complains about the location of the store

=\frac{200}{775}\times 100 %

=25.81%

Lydia graphed ΔDEF at the coordinates D (−2, −1), E (−2, 2), and F (0, 0). She thinks ΔDEF is a right triangle. Is Lydia's asser
alukav5142 [94]

Answer:

No; the slopes of segment EF and segment DF are not opposite reciprocals.

Step-by-step explanation:

The slope between two points O(e, f) and X (g,h) is given as:

slope\ of\ |OX|=\frac{h-f}{g-e}

The slopes of segment EF and segment DF are given below:

slope\ of\ |EF|=\frac{0-2}{0-(-2)}=-1\\\\slope\ of\ |DF|=\frac{0-(-2)}{0-(-1)}=2\\

For triangle DEF to be a right triangle, DF and EF are supposed to be perpendicular to each other. Two line are said to be perpendicular if the product of their slope is -1, i.e the slope of one line is the negative reciprocal (opposite reciprocal) of the other line.

Since the slope of DF and EF are not opposite reciprocals,  ΔDEF is not a right triangle.

Luke and Matt went fishing. Luke caught 4 fish, each weighted 7/8 of a pound. Matt caught 6 fish, each weighted 3/4 of a pound.
Andrews [41]

Matt caught more pounds of fish.

Step-by-step explanation:

Given,

Fish caught by Luke = 4

Weight of each fish = 7/8 of a pound

Weight of 4 fish = \frac{7}{8}*4 pounds

Weight of 4 fish = 3.5 pounds

Fish caught by Matt = 6

Weight of each fish = 3/4 of a pound

Weight of 6 fish = \frac{3}{4}*6

Weight of 6 fish = \frac{18}{4}=4.5\ pounds

Therefore,

Matt caught more pounds of fish.
