Answer:
4
Step-by-step explanation:
Since the question does not specify if you are rounding up or down, just round down to four from 4 1/6. 4 1/6 is closer to 4 than it is to 4 3/6 or 4 1/2.
3. 16 months
60x=947
x=15.78333… = 16 months
4. 46 months
400x=18,091
x=45.2275 = 46
Every hour, the number of liters decreases by 0.5 liter.
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x
1 = 53
2 = 115
3 = 107
4 = 73
5 = 115
6 = 66
I’ll do the rest later
