Answer:
0.375
6/16
37.5%
Step-by-step explanation:
Can't be above 50% because that would be 4/8, which rules out 62.5%, 50%, and 3.75, and 3.75% is super low, which leaves 4 answers, but 1/4 doesn't equal any of the others. Also, 3/8 x 2 is 6/8, and 0.375 = 37.5%
Since
Is a perfect square, we can think of the "-6" at the end as a "+4-10" and we have
Which is the required form
Let's solve your equation step-by-step.
<span><span><span><span>4<span>x^2</span></span>+<span>28x</span></span>−32</span>=0
</span>Step 1: Factor left side of equation.
<span><span><span>4<span>(<span>x−1</span>)</span></span><span>(<span>x+8</span>)</span></span>=0
</span>Step 2: Set factors equal to 0.
<span><span><span>x−1</span>=<span><span><span>0<span> or </span></span>x</span>+8</span></span>=0

Answer:
102 ; 357 ; 238 ; 153
Step-by-step explanation:
Given that:
Total number of students in Southbrook middle school:
12% of students do not participate:
Number of students who do not participate :
(12/100) * 850
0.12 * 850 = 102
Only one sport = 42%
Percentage of students = 42%
Total number of students = 850
0.42 * 850 = 357 students
Two sports = 28%
Percentage of students = 28%
Total number of students = 850
0.28 * 850 = 238 students
Three or more sports:
Percentage of students = 18%
Total number of students = 850
0.18 * 850 = 153
Answer:
Original Price= $50 000
Year 1=$50 000*1.10= $55,000
Year 2=$55 000*1.10= $60 500
Year 3=$60 500*1.10=$66 550
After 2 years it will be $66 550
