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
Surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters
<u>Solution:</u>
Given that
Shape of the roof is square pyramid.
Base length of square pyramid roof = 10 meters
Slant height of square pyramid roof = 12 meters
Need to calculate the surface area of the roof
Where s is side of square base and l is slant height.
In our case s = 10 meters and l = 12 meters
On substituting the given values in formula we get
Surface area of square pyramid 
Hence surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters.
Answer: Yes
Step-by-step explanation:
Each value of y maps onto one value of x.
I do not think so, because it has to be the same number.
Ex: 5,539 - in this the 5 in the thousands place is greater than the 5 in the hundreds place
