Answer:
5 miles.
Step-by-step explanation:
Consider the question: Jinghua hiked 4 1/2 miles through the woods in 2 1/4 hours. She hiked the return trip at the same average rate but by a different route taking 2 1/2 hours. How many miles did Jinghua hike on the return trip ?
First of all, we will find Jinghua's speed using given information as:

Convert mixed fractions into improper fractions:



Using property
:


We know that distance is equal to the product of speed and time.

Since we have been given that Jingua hiked the return trip at the same average rate, so distance covered by her on return trip would be speed (2 miles her hour) times given time (2 1/2 hours).



Therefore, Jingua hiked 5 miles on her return trip.
Answer:
7
Step-by-step explanation:
An equilateral triangle has a semiperimeter of 6 meters.
Heron’s formula: Area = StartRoot s (s minus a) (s minus b) (s minus c) EndRoot
An equilateral triangle has a semiperimeter of 6 meters. What is the area of the triangle? Round to the nearest square meter.
2 square meters
7 square meters
20 square meters
78 square meters
First we find the area 10 x 21 = 210 then we multiply 210 x .70 and we get 147.00 total cost. d. 147.00
