you cant do that
Step-by-step explanation:
Answer:
1. 5² is 25 yards
2. 7² is 49m
3. 8² is 64cm
4.draw a square, make one side 6 feet then do 6² which is 36feet
5. do the same thing then write 10 inches on one side and 10² is 100 inches.
6. 7x3= 21 ft
7. 5x4= 20 in.
8. 2x8= 16 yd

Answer:
Yes it does.
Step-by-step explanation:
Because if it was a decay of 4 percent it would have been
y=8(.96)
Answer:
m/100 or 1/100 M
Step-by-step explanation:
If we are trying to find the percent of a value, we divide by 100
Answer:
# of students = 393, # of non-students = 104
Step-by-step explanation:
We have a system of equations (# of students = s, # of non-students = n):
1. Total people attended: s + n = 497
2. Total earnings: 2.5s + 4.5n = 1450.5
We can <em>change the first equation to n = 497 - s</em>, and <em>substitute that into the other equation: 2.5s + 4.5(497 - s) = 1450.5</em>
Expand: 2.5s + 2236.5 - 4.5s = 1450.5
Subtract: 2.5s - 4.5s = 1450.5 - 2236.5
Simplify: -2s = -786
Divide: s = 393
Plug into first equation: 393 + n = 497
Subtract: n = 104
