52 because 4 feet is 48 inches 9 (which is like 1 feet is 12 inches) and 48 plus 4 equals 52
Answer:
30 meters
Step-by-step explanation:
If she ran for 5 seconds, 6 meters per second. All you do is 5x6 and you get 30
It is the first one ...w= 3z+2
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2
a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78
sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
I hope this helps with your answer
