Find the slope using the following two points (19.3) and (20,3)
Sidana [21]
The slope is 0 I’m pretty sure because it is a horizontal line, if it was a vertical line it would be undefined

A cheetah runs at a rate of 75 miles per hour about how many leaders can it run in 5 seconds​
umka21 [38]

Answer:

Distance in meters D = 167.75 meters

Step-by-step explanation:

Distance covered in 5 seconds is given by:

Distance, D = Speed (S) X Time (T)

Where,

Distance = ?

Speed = 75mph

Time = 5s

Since we are calculating distance in meters, we have to convert 75miles per hour to meters per second

75mph = 75miles/1hr X 1km/0.621miles X 1000m/1km X 1hr/60mins X 1min/60s

            = (75X1000) / (0.621X60X60) meter per second

            = 75000/2235.6 meter per second

            = 33.55 meter per second

∴ Distance D = 33.55 meter per second X 5 seconds

                      = 167.75 meters

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w
netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

\frac{1}{2} \times 100 = 50

Add both skateboarding and walking

30\% + 50\%\\\\= 30 + 50\\\\= 80

Now, subtract that from a whole percent

100 - 80 = 20\\\\20\%

Convert it to a decimal

20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
