Answer:
<em>x ≥ 2</em>
Step-by-step explanation:
Distribute 8:
8 (3.5x - 2) ≥ 40
28x - 16 ≥ 40
Add 16:
28x ≥ 40 + 16
28x ≥ 56
Divide by 28:
x ≥ 56 ÷ 28
x ≥ 2
You can either find the roots of the quadratic formula using the quadratic formula two find the halfway point or you can use the formula t=-b/2a. Both of the two methods gives you the axis of symmetry (the t value for the vertex).
I will use the second method since I don't like using the quadratic formula.
t=-32/(2x-16)
t=1 second
After you find the t value for the axis of symmetry, you plug it into the formula of the graph to find the height.
h=-16+32+14
h=30 feet
Answer:
70% of the meeting is left.
Step-by-step explanation:
Hi, to answer this question, first, we have to convert the hours to minutes.
Since 1 hour = 60 minutes
For 2 hours:
1 /60 = 2/x
x = 2 (60)
x = 120 minutes
So, a scout meeting last 120 minutes (2 hours)
36 minutes already spent.
120-36 = 84 minutes left
So, if 120 is the 100% of the meeting, for 84 minutes:
120/100 = 84/x
1.2 =84/x
x = 84/1.2
x = 70%
70% of the meeting is left.
