Step-by-step explanation:
12x - 16 = 2x - 21
10x - 16 = -21
10x = -5
x= -0.5
Answer:
25.1 ft
Step-by-step explanation:
To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).
So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!
Answer:
250 students
Step-by-step explanation:
Given data
Let the total number of students be x
Number of students that plays instrument = 10
Hence
40% of x = 10
40/100*x= 100
0.4x=100
x=100/0.4
x= 250
Hence there are 250 students in total
Answer:
$25,193.17
Explanation:
Given:
• Principal Felipe borrowed, P=$8000
,
• Annual Interest Rate, r=16.5%=0.165
,
• Compounding Period, k=12 (Monthly)
,
• Time, t=7 years
We want to determine how much he will owe after 7 years.
In order to carry out this calculation, use the compound interest formula below:

Substitute the values defined above:

Finally, simplify and round to the nearest cent.

After 7 years, Felipe will owe $25,193.17.
