1 answer:

4 0

You only listed 8 kids...so the average of the 8 kids listed is 150.125!
The process:
You add all kids heights then divide by the amount of children. Like this-
155+160+145+150+147+152+144+148=1201
Then you divide by 8 to get 150.125

Find the measure of an angle and its complement if one angle measures 24 degrees more than the other.

Vera_Pavlovna [14]

Complementary angles = 90

x+y =90

y=x+24

substitute this in to the equation

x+x+24=90

2x+24=90

subtract 24 from each side

2x = 66

divide by 2

x=33

y = 33+24

y=57

If susan, janice, and melvin take 2.0 hours to walk to their school at a rate of 1.0 m/s, how far is their school from their hou

RideAnS [48]

Answer:

7.2 km

Step-by-step explanation:

Given that:

Hours taken = 2 hours

Walk rate = 1 m/s

Distance = Speed * time

Time taken in seconds = 2 * 60 * 60 = 7200 s

Hence,

Distance = 1 m/s * 7200s

Distance = 7200 meters

Distance in km = 7200 / 1000 = 7.2 km
