Answer: you travelled 10 km
Step-by-step explanation:
Pam jogged up the hill at 6 km/h.
Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.
Time = Distance/speed
Pam jogged up the hill at 6 km/h.
Time spent in jogging up the hill would be
x /6
She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be
x /10
If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33
Therefore
x /6 + x/10 = 1.33
10x + 6x = 80
16x = 80
x = 80/16 = 5
Total distance travelled up and down the hill would b
5 × 2 = 10 km
Answer:
100 gm calcium, 30gm carbon and 120gm oxygen
Step-by-step explanation:
10% of a kg is 100gm of calcium, 3% of 1 kg is 30gm of carbon and 12% of a kg is 120gm of oxygen
1.
![AB \cong CD](https://tex.z-dn.net/?f=AB%20%5Ccong%20CD)
congruent means equal
2.
![AB \cong BC](https://tex.z-dn.net/?f=AB%20%5Ccong%20BC)
bisect means to cut a line segment in two equal parts
Above the AB, CD, AB, and BC there has to be a line. I could not write that because LaTeX doesn't allow it.
3.
![2x + 5 = 4x-8](https://tex.z-dn.net/?f=2x%20%2B%205%20%3D%204x-8)
You set both equal to each other
4.
![PA \cong AT](https://tex.z-dn.net/?f=PA%20%5Ccong%20AT)
midpoint means that both line segments are equal
Same thing goes for PA, and AT. You need to draw a line above it.
Hope that helped :)
