Answer:
Convert kilometres to metres. Since kilo- means 1 000, one kilometre (km) is equal to 1000 metres (m). Multiply the number of kilometres by 1 000 to get the same measurement in metres. For example, 75 kilometres =
Step-by-step explanation:
Answer: x ≥ -24
Step-by-step explanation:
I think the equation is supposed to be written as an inequality.
3 - x/2 ≥ 15
Step 1: Subtraction property of equality
-x/2 ≥ 12
Step 2: Multiplication property of equality
-x ≥ 24
Step 3: Multiplication property of equality
x ≥ -24

Step-by-step explanation:
A candle 6 inches high burns at a rate of 1 inch every 2 hours for 5 hours. The candles burning rate is 0.5 inch per hour).
Then
- a cnadle height after first hour is 6 - 0.5 = 5.5 inches;
- a candle height after first two hours is 5.5 - 0.5 = 5 inches;
- a candle height after first three hours is 5 - 0.5 = 4.5 inches;
- a candle height after first 4 hours is 4.5 - 0.5 = 4 inches;
- a candle height after first 5 hours is 4 - 0.5 = 3.5 inches.
The candles height h (in inches) at any time t (in hours) is modeled by
![h(t)=6-0.5t](https://tex.z-dn.net/?f=h%28t%29%3D6-0.5t)
The domain of this function is
![0\le t\le 5](https://tex.z-dn.net/?f=0%5Cle%20t%5Cle%205)
The range og this function is
![3.5\le h(t)\le 6](https://tex.z-dn.net/?f=3.5%5Cle%20h%28t%29%5Cle%206)
the answer is 62.9, I hope it helped
I think its C because you just have to follow the expressions pattern i hope this helps good luck!!
