Option b
Step-by-step explanation:
- Calcium has atomic no-20
- Hence it has 20 protons
- Silicon has atomic no 14

Total:-

The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b
would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0
y=-10
8/14 , 12/21, 16/28, 20/35
Answer:
22%
Step-by-step explanation:
Divide 2,650 by 100:

Answer:
speed = 54.5 miles/hr
Step-by-step explanation:
speed = distance/time
distaance = 735.75
time = 7 + 6.5 = 13.5
speed = 735.75 / 13.5
speed = 54.5 miles/hr
