Answer:
Step-by-step explanation:
volume of sphere = 4πr³/3
= 4π×512/3
≈ 2143.6 cm³
To solve this question, we should set up a system of equations. Let a represent the number of passengers on bus 1 and b represent the number of passengers on bus 2.
From the question, we can set up the two equations:
1/3(a+b)=24
a=34
To solve this system, it is easiest to substitute the value we know for a into the first equation. If we do this, we get:
1/3(34+b)=24
To simplify this equation, we need to divide both sides by 1/3 in order to get the variable b alone. After simplifying, we get the equation:
34 + b = 72
Finally, we subtract 34 from both sides to get the variable b alone.
b = 38
Therefore, there were 38 passengers on bus 2.
Hope this helps!
Answer:
51.2
Step-by-step explanation:
15x = 120
x = 8
so now we know that 2 sides of the bigger triangle are 24 and 8
now
96 = 5x
x = 19.2
19.2 + 24 + 8
