Answer:
Step-by-step explanation:
Given that:
Batting average = 0.25 after 160 times at bat;
Batting Average = Number of hits / number of times at bat
0.25 = number of hits / 160
Number of hits = 0.25 * 160 = 40
He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average
Hence,
New average = number of hits / number of times at bat
0.333 = (number of hits + x) / (160 + x)
0.333 = (40 + x) / (160 + x)
Answer:
482.84 cm
Step-by-step explanation:
Circumference = πD
π*49 = 153.94 (We can leave it as it is because there are two halves to the circle on either side of the training track)
81*2 = 162 (There are two 81 meter lines)
153.94+162 = 315.94m
The length of the training track is 315.94m
Hope this helps! :)

Answer:
x=2.4
Step-by-step explanation:
2(x+1)+6=20-3x
We simplify the equation to the form, which is simple to understand
2(x+1)+6=20-3x
Reorder the terms in parentheses
+(+2x+2)+6=20-3x
Remove unnecessary parentheses
+2x+2+6=+20-3x
We move all terms containing x to the left and all other terms to the right.
+2x+3x=+20-2-6
We simplify left and right side of the equation.
+5x=+12
We divide both sides of the equation by 5 to get x.
x=2.4
