Answer:
√(V / π × h), where V is the volume of the cylinder, h is the height, and π(Pi) is a mathematical constant with an approximate value of 3.14
Answer:
The total number of hikers are 427
Step-by-step explanation:
Let:
The number of bikers = x
The number of hikers = y
There are 178 more bikers than hikers
y = x + 178
if there are 676 people in the park total how many people are hikers?
Hence:
x + y = 676
we substitute x + 178 for y
x + x + 178 = 676
2x + 178 = 676
2x = 676 - 178
2x = 498
x = 498/2
x = 249
y =x + 178
y = 249 + 178
y = 427
Therefore:
The number of bikers = x = 249
The number of hikers = y = 427
The total number of hikers are 427
Answer:
Step-by-step explanation:
The given equations are:
2a+7b=0 and 3a-5b=31
Statement Reason
1. 10a+35b=0, 21a-35b=217 (Multiply first equation by 5 and second by 7)
2. 31a=217 (Adding both the equations)
3. a=7 (Dividing both sides by 31)
4. 2(7)+7b=0 (Substituting a=7 in first equation)
5.14+7b=0 (solving step 4)
6. 7b=-14 (Subtracting 14 on both sides)
Answer:
every number you can think of
Step-by-step explanation:
6x - 3y = -6
=> 3(2x - y) = -6
=> 2x - y = -2
And you see there's a problem here. The question doesn't have enough information because x and y can be every numbers.
Take an example, x can be 200 and y can be 402 or x can be 5 and y can be 12.
Rewrite or check the question again so I can solve this :)
Answer:
√2, pi.
Step-by-step explanation:
An irrational number cannot be written as a fraction a/b where a and b are integers ( not = 0)..
