Answer:
e ≥ 2w
Step-by-step explanation:
To make this easier, let us consider the case of Eliza being exactly twice as old as wendy
that would mean that twice the age of Wendy is the age of Eliza
e = 2w
but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy
Hence, the symbol '=' will be replaced by '≥'
Hence, the correct relation is
e ≥ 2w
Answer:
Step-by-step explanation:
After 5 hour the stock price would drop to $30.87 after 28 hours it would $-2.48
$1.45x$5=$7.25
$38.12-7.25=$30.87
$1.45x$28=$40.6
$38.12-$40.6=$-2.48
5hr=$30.87
28hr=$-2.48
Answer: Yes
Step-by-step explanation:
We will assume that each bulb is of 100 kW (kilowatt).
We will calculate how much energy in kilowatt-hours the light bulb will use per year in kilowatts, by the number of hours in a year.
We have, 100 kW = 0.1 kW so the energy consumed in one year is,
0.1 \times 8760=876.0\text {kWh} Since there are 8760 hours in one year. It is given that there are 9 bulbs so we need to have, 876 \times 9 = 7884 \text {kWh}
It is given that 1 ton of coal produces 2460 kWh, so 4 tons of coal will produce, 4\times 2460= 9840 \text {kWh}
We can observe that 4 tons of coal is producing 9840 kWh which is mroe than 7884 kWh. So, yes, 4 tons of coal can produce enough power to light 9 bulbs for a year
