Answer:
18 KM/H.
Step-by-step explanation:
S= D / T or 500 meters / 100 seconds. The answer is 5M/S. To calculate the speed per hour, multiply the distance by 3600 (60 seconds times 60 minutes equals one hour). 5 x 36oo = 18 KM/H.
Answer:
A= 0.5 x (a+b) x h
124 = 0.5 x (12+19) x h
124 = 15.5 x h
÷15.5
h = 8cm
0.5x(12+19) x 8 does gives 124
Thus, height is 8cm.
Hope this helps!
Answer:
-3 is the slope of the line.
Step-by-step explanation:
You have to rearrange the equation to slope intercept form, y=mx+b.
3x+y=14
-3x -3x
y=-3x+14
Answer: 11
= 10.67707825
