Let A be the speed of hiker A and B the speed of hiker B.
let's say that B is faster than A, so B=A+0.5
we know that they met after 2 hours, and the distance each walked after 2 hours is given by:
One of the hikers travels at 4 miles per hour, the other one at 4.5 miles per hour
Answer:
B
Step-by-step explanation:
B) because both result in the equation 8 x = 400, which simplifies to x = 50

It's w + 15. As it is increasing by 15, 15 is added onto it.
ANSWER: The expression that represents the volume of the cone written in terms of π is: 18π in^3
We know that PQ is 21 cm and QR is 5 cm. There are only 2 possible answer for this and you use only one formula. It's called the Pythagorean theorem.
The first possible is this. If the hypotenuse(the longest side of a triangle) is PR, we do:
a² + b² = c² ←Fill in the numbers
21² + 5² = c²
441 + 25 = c²
466 = c²
√466 = 21.12 cm←Possible length
The second possible is this:
5² + b² = 21²
25 + b² = 441
b² = 441 - 25
b² = 416
√416 = 20.4←Another possible answer
