A=68
Step-by-step explanation:
Answer: for 3) 427 hikers
Step-by-step explanation: b + 178 + b = 676
2b + 178 = 676
2b = 498
b = 249 bikers
h = 249 + 178 = 427 hikers
Step-by-step explanation:
in two no. question what is in the power of X is that 3 or 5
Here is a photo of what I chose as my equivalent numbers (Red represents my work, blue represents which step comes next, and highlighter shows what the answer is). My reasoning that 1/2 and 5/10 are equivalent is because 5/10 divided by 5/5 is 1/2.
Volume of a sphere is calculated with V=(4/3)πr^3
We have the value of r, which is 6.
Plug in the value, and solve.
V=(4/3)π(6^3)
V=(4/3)π(216)
V=π(288)
V=904.7786842
So, C. is your answer.
