Answer:
Step-by-step explanation:
Basically, you want to know interest. I = prt is the formula. 'I' will be left blank b/c that's unknown. P is principal, 5000. R is rate, 4%, or 0.04 when turned into a decimal. T is time, 7 years. So now when using the formula, it will all become I = 5000(0.04)(7). What that means is you first multiply 5,000 by 0.04, getting 200. Then when you multiply 200 by 7, it's 1,400, which will leave you with I = 1,400. Interest is 1,400.
1) Solve for radius
Radius = r
2) Solve for height
Height = h
3) in calculator enter : ( 2 x 3.14 x radius squared ) + ( 2 x 3.13 x radius x height )
17/20 is 85% in its simplistic form... first put 85/100 and then divide both numerator and denominator by 5.
Answer:
Total number of people in the stadium = 520
Step-by-step explanation:
Let the total number of people in the stadium = x
Since, 25% of the fans are teenagers, number of teenagers in the stadium
= 25% of x
= 
= 0,25x
If the number of teenagers in the stadium = 130
0.25x = 130
x = 
x = 520
Therefore, total number of fans in the stadium = 520.
