Answer:
<em>The National football league has </em><em>464 more players</em><em> than the Major League baseball.</em>
Step-by-step explanation:
Since there are 30 teams in the Major league baseball and there are 40 players in each team, this means that the total number of players in the Major league baseball is:
30 × 40 = 1200 players
Since there are 32 teams in the National football league and there are 52 players in each team, this means that the total number of players in the National football league is:
32 × 52 = 1664 players
Therefore, the difference in the number of players in both leagues is:
<em>1664 - 1200 = 464 players</em>
<em></em>
Therefore, the National football league has <em>464 more players</em> than the Major League baseball.
Answer:
Let x be the number of tickets sold to adults and y the number sold to students:
x + y = 315. But we know that y was double x, then :
y = 2x
Plug the value of y (in the 1st equation) by 2x:
x+ 2x = 315
3x = 315
and x = 105 (which is the number of tickets sold to adults

Answer:
38.28cm²
Step-by-step explanation:
The area of the figure can be determined by expression the figure as two shapes.
A semicircle and trapezium;
Area of shape = Area of semicircle + Area of trapezium
Now;
Area of semicircle = 
Where r is the radius, which is 
= 2cm;
Area of semicircle = 
= 6.28cm²
Area of trapezium;
= 
a and b are the base length = 6cm and 10cm
h is the height = 4cm
Input the parameters and solve;
= 
= 32cm²
The area of the shape = 6.28cm² + 32cm² = 38.28cm²
