Answer:
The second box plot best represents the data
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one
Answer:
93
Step-by-step explanation:
Add: 67+41+91+68=267
Subtract: 360-267=93
Hope this helps
26x3=78
78-x=72
x=6
She needs to buy at least 6 more to have enough for 26 students
Answer:
