Lee watches tv for 3 hours per day. During that time the tv consumes 250 watts per hour. Electricity costs 12 cents/1 kilowatt-hour. How much does it cost to run the tv does 30 days?
Answer:
270 dollars
Step-by-step explanation:
He's going to watch 90 hours of tv in 30 days, so multiply 90 hours x 250 watts, Which is 22500 watts over 30 days, then convert to kilowatts which would be 22.5 kilowatts total. He used .25 kilowatts an hour every day. Then multiple 22.5 x 12 cents to get your answer 270. He paid 270 dollars for electricity for the tv.

What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
A toy store offers an additional 25% discount on board games that have already been reduced by 30%.
let the the price of toy be $100.
So, the price after 30% discount
= 100 - 100 x 0.30
= 100 - 30
= $70
and, additional 25% discount
= 70 - 70 x 0.25
= $52.5
Now, if discount is 55% then price would be
= 100 - 100 x 0.55
= $45
Hence, the case is not same.

The slope of the line graphed in the coordinate grid will be;
⇒ m = -4/5
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The line graphed in the coordinate grid is shown in figure.
Now,
Let two points on the graph of the line are (5, 0) and (0 , 4)
We know that;
Slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is,
⇒ m = (y₂ - y₁) / (x₂ - x₁)
Hence, Slope of the line passing through the points (5, 0) and (0 , 4) is,
⇒ m = (y₂ - y₁) / (x₂ - x₁)
⇒ m = (4 - 0) / (0 - 5)
⇒ m = 4 / (-5)
⇒ m = -4/5
Thus, The slope of the graph = - 4/5

Answer:
x= 8.9 cm
Step-by-step explanation:
First, since we know that the radius of the circle is 5 centimeters, we know that the diameter of the circle and the hypotenuse of the triangle is 10 centimeters long. Then you use the pythagorean theorem to find out the length of side x. The equation would be: 4.5^2 + x^2= 10^2. Next, you simplify the equation by squaring the squares to get. 20.25 + x^2= 100. Finally, you would subtract 100 and 20.25 to get 79.75 and take the square root of that number to get your x value. x= [tex]\sqrt{79.75}[/tex]. When you do this equation you come out with x=8.93028554975 and then round it to the nearest tenth which is 8.9 cm.

2/5m to cm pls plshghhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Answer:
40cm
Step-by-step explanation:
Centimeter means "one hundredth of a meter," so:
1 m = 100 cm
How many meters times 100 will get you how many cm:
2/5m = ? cm
2/5 (100) = ? cm
200/5 = ? cm
40 = ? cm
2/5m = 40 cm
what is the percent change of 2880 to 3168
Answer:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
10% = 10/100 = 10 ÷ 100 = 0.1.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 10% of its value.
Percentage increase = 10% × 2,880
New value =
2,880 + Percentage increase =
2,880 + (10% × 2,880) =
2,880 + 10% × 2,880 =
(1 + 10%) × 2,880 =
(100% + 10%) × 2,880 =
110% × 2,880 =
110 ÷ 100 × 2,880 =
110 × 2,880 ÷ 100 =
316,800 ÷ 100 =
3,168
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 2,880 =
3,168 - 2,880 =
