Step-by-step explanation:
1: B $3.85
2: C The rabbit; 14 miles per hour
3: C 2 1/2 miles
1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85
2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.
Subtract: 35-21= 14. So the rabbit is faster by 14 miles.
3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:
1/2 mile = 1/5 hour
1 mile = 2/5 hour
1 1/2 mile = 3/5 hour
2 mile = 4/5 hour
2 1/2 mile = 1 hour
So, Randy will travel 2 1/2 miles in a hour.
Answer:
a) $7.27344
b) 263.974 hours
Step-by-step explanation:
a)
+) 1 day = 24 hours
+) The cost for 1000 watts each hour is $0.05051 so that each hour use of 1 watt costs: $0.05051 / 1000 = $0.00005051
+) Each hour, each electric heater uses 1200 watts costs: $0.00005051 x 1200 = $0.060612
=> In 24 hours, to heat each electricity heater costs: $0.060612 x 24 = $1.454688
=> In 24 hours, to heat 5 electricity heaters costs: $1.454688 x 5 = $7.27344
<em>So that it costs $7.27344 to heat her house for 1 day</em>
<em />
b)
As calculated, the cost to use 1 watt in one hour is $0.00005051
=> The cost to use 75 watts in one hour is: $0.00005051 x 72 = $0.00378825
Assume that the hours of using 72 watts to cost $1 is x (hour)
So that: $0.00378825 * x = $1
=> x = 1/ 0.00378825= 263.974 hours
<em>It takes 263.974 hours for a 75-watt lightbulb to stay on to result in $1 electricity charges</em>
