540 divided by 15 = 36, therefore there are 36 seats in each row.
Answer:
y = -4x - 1
Step-by-step explanation:
Do the slope formula first to find the slope. Next do point slope form to find the y intercept and write the equation in slope intercept form.
Answer:
A 3/4
Step-by-step explanation:
Set up equation to find the percentage 2/7 equals:
Variable x = percentage
2/7 = x/100
Cross multiply:
2 × 100 = 7 × x
200 = 7x
Divide:
28.57142... = x
About 30% (I rounded to 30% because it is a nice number to use when all other numbers end in 5 or 0)
If Alexa has about 30% saved, she will need to save about 70% more. Find the solution that is closest to 70%.
A is 3/4 which comes out to 75%. So far, this sounds like the best answer. Let's check the others just in case.
B is 1/2, or 50% which isn't as close as A was to 70%.
C is 1 1/4 which means 125% needs to be saved. This would mean Alexa is in debt and hasn't saved any money which is not the case.
D is 1/4, or 25%. The trick here is that she's saved about 30% so 25% is closest, but we are looking for how much <em>more</em><em> </em>she needs to save.
Assuming 100 kw bulb
<span>We'll start by figuring out how much energy in
kilowatt-hours the light bulb uses per year. We multiply how much power it uses
in kilowatts, by the number of hours in a year. That gives 0.1 kW x 8,760 hours
or </span>876 kWh x 9 bulbs = 7884 kWh
The electricity produced by 4 tons x 2460
kWh/ton = 9840 kwh
<span>Since the produced electricity is bigger so it
is enough</span>
3.3 and 3.30 are equivalent to 3.300
