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.

There is a TV that is $189.00. There is a coupon offering 15% off any television purchase. If the sales tax on the TV is 8%, how much will the TV cost total?
Answer:
175.77 dollars

15% off 189.00 is 160.65 then you take that answer and add on the sales tax from the original price. Doing 189.00 x 8 percent gets you 15.12 dollars.
Add 160.65 + 15.12 to get 175.77 dollars.

Two friends decide to rent an apartment and split the cost evenly. They each paid $752 towards the total move in cost which included first and last month’s rent and a security deposit of $499. What will be the cost of rent per month for each of them?
Answer:
They will both pay $63.50 a month
Step-by-step explanation:
Since they paid $752 total and $499 as a security deposit, you subtract the two, getting you $253 in rent for both months. Divide that answer by 2 to get $126.5 to get how much they payed each month together, then divide by 2 again to get how much they each payed which is $63.50
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

The time for one complete swing of a pendulum can be modeled by the formula P=2π√L/32 where L represents the length of the pendulum in feet and P represents the period of the pendulum in seconds. If the pendulum's period is 2.4 seconds, which of the following best represents the length of the pendulum?
A. 1.7 ft
B. 5.4 ft
C. 4.7 ft
D. 4.4 ft
Answer:
two ways to get this
1 by unit analysis
l / g → m / (m/s^2) → s^2
so you'd need
root of l/g to get s (time units)
2
from the formula
T = 2 pi sqrt(L/g)

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

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 =
