Lee watches TV for 4 hours per day. During that time, the tv consumes 150 watts per hour. Electricity cost (12 cents)/(1 kilowatt-hour). How much does Lee's tv cost to operate for a month of 30 days?
Answer:
$2.16
Step-by-step explanation:
150 * 4 = 600watt-hours
600 = 0.6kilowatt-hours
0.6 * 30 = 18kilowatt-hours
18 * 0.12 = $2.16

Sam is getting ready for a big date when he realizes that he has no money. his roommate, Bill, also has no money, but he has a credit card. knowing that nobody will let Sam use Bill's credit card, Sam asks Bill to put out a cash advance for $120.00. Bill agrees under the condition that Sam is responsible for all interest that accrues on the cash advance which is 30% interest rate, compounded monthly. The $120 cash advance is repaid in monthly installments over 5 years. How much should Bill ask Sam to pay in interest for the cash advance?
Answer:
b 112.80
Step-by-step explanation:
took test on edge
The interest that accrues on the initial down payment at 30% interest rate is $408 .
What is interest?The term interest refers to money that accrues on a principal sum. It is commonly employed in the parlance of borrowing money.
Since it is a compound interest;
A = P(1 + r/n)^nt
Where;
A = amount
P = principal
r = rate
n = number of times compounded per year
t = total time taken
A = 120(1 + 0.025)^12 × 5
A = $528
A = P + I
I = A - P
I = $528 - $120
I = $408

In ΔQRS, r = 1.5 inches, ∠S=23° and ∠Q=22°. Find the length of s, to the nearest 10th of an inch.
Answer:
0.8 inches
Step-by-step explanation:
< R = 180-23-22 = 135°
the length of s = 1.5 × sin 23° / sin 135°
= 1.5 × 0.391 / 0.707 = 0.5865/0.707
= 0.8 inches

A motorboat travels 204 kilometers in 6 hours going upstream. It travels 372 kilometers going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 48 km/hcurrent: 14 km/hStep-by-step explanation:
The upstream speed is ...
u = (204 km)/(6 h) = 34 km/h
The downstream speed is ...
d = (372 km)/(6 h) = 62 km/h
The speed of the boat in still water is the average of these values:
b = (34 kph +62 kph)/2 = 48 kph
The speed of the water is the difference between the boat's speed and the speed made good:
w = 48 -34 = 14 . . . km/h
The rate of the boat in still water is 48 km/h. The rate of the current is 14 km/h.
the figure above, not drawn to scale, consists of a triangle resting on a square of side 5cm. the height of the triangle is 4cm. what is the total area of the figure?
Answer:
5x4x2
Step-by-step explanation:
The total area of the figure id 35 square cm.
What is area?The amount of space taken up by a two dimensional space is called area.
What is the formula for the area of triangle?The formula for the area of a triangle is
[tex]A = \frac{1}{2} (b)(h)[/tex]
Where,
A is the area of triangle.
b is the base of a triangle.
h is the height of the triangle.
What is the formula for the area of square?The formula for the area of square is
[tex]Area = a^{2}[/tex]
Where,
a is the side length of square.
According to the given question.
A triangle is resting on a square.
Side length of square, a = 5cm
So, the area of square = [tex]5^{2} = 25 square cm[/tex]
Also, a triangle with height 4cm.
Since, the triangle is resting on a square.
⇒ Base length of the triangle = 5cm
So, the area of triangle = [tex]\frac{1}{2} (5)(4)= 10 square cm[/tex]
Therefore,
The total area of the given figure = Area of square + Area of triangle
⇒ Total area of figure = (25 + 10) square cm
⇒ Total area of figure = 35 square cm
Hence, the total area of the figure id 35 square cm.

Step-by-step explanation:
Given
The attached plot
Required
The line of the best fit using [tex](8,80)[/tex] and [tex](2,20)[/tex]
We have:
[tex](x_1,y_1) = (8,80)[/tex]
[tex](x_2,y_2) = (2,20)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{20 - 80}{2- 8}[/tex]
[tex]m = \frac{-60}{-6}[/tex]
[tex]m = 10[/tex]
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 10(x - 8) + 80[/tex]
Expand
[tex]y = 10x - 80 + 80[/tex]
[tex]y = 10x[/tex]

find the sin of whixh angles equak 5/6
Answer:
arcsin(5/6) = 56.44 degrees, or 0.99 radian
Step-by-step explanation:
Write out sin x = 5/6.
Then write out the inverse function: arcsin 5/6 = x.
Use a calculator's 'arcsin' function to determine the angle x:
arcsin(5/6) = 56.44 degrees, or 0.99 radian
. Let X and Y be random variables of possible percent returns (0%, 10%,
15%, and 20%) for stock A and, with the joint probability distribution given
in the Table below:
Joint Probability Distribution for Random Variables X and Y
Y Return
X Return 0 5 10 15
0 0.0625 0.0625 0.0625 0.0625
5 0.0625 0.0625 0.0625 0.0625
10 0.0625 0.0625 0.0625 0.0625
15 0.0625 0.0625 0.0625 0.0625
(a) Find the marginal probabilities.
(b) Determine if X and Y are independent.
(c) Find the means and variances of both X and Y.
(a) The marginal distribution of X is
Pr(X = x) = ∑ Pr(X = x, Y = y)
… = 0.0625 + 0.0625 + 0.0625 + 0.0625
… = 0.25
That is, the first equality follows from the law of total probability, with the sum taken over y from {0, 5, 10, 15}. Each probability Pr(X = x, Y = y) is given in the table to be 0.0625.
Similarly, the marginal distribution of Y is
Pr(Y = y) = 0.25
(b) Yes, they're independent because
Pr(X = x, Y = y) = 0.0625,
and
Pr(X = x) Pr(Y = y) = 0.25 • 0.25 = 0.0625.
(c) The mean of X is
E[X] = ∑ x Pr(X = x)
… = 0.25 ∑ x
… = 0.25 (0 + 5 + 10 + 15)
… = 7.5
and you would find the same mean for Y,
E[Y] = 7.5
The variance of X is
V[X] = E[X^2] - E[X]^2
… = (∑ x^2 Pr(X = x)) - 7.5^2
… = 0.25 (∑ x^2) - 56.25
… = 0.25 (0^2 + 5^2 + 10^2 + 15^2) - 56.25
… = 31.25
and similarly,
V[Y] = 31.25
(each sum is taken with x and y from {0, 5, 10, 15})

Anthony can either play 4 hours of video games or read 12 chapters of a book. What is Anthony's opportunity cost of playing one hour of video games?
Answer:
The opportunity cost of playing an hour of video games is not reading 3 chapters of a book.
Step-by-step explanation:
Given that Anthony can either play 4 hours of video games or read 12 chapters of a book, to determine what is Anthony's opportunity cost of playing one hour of video games, the following calculation must be performed:
4 = 12
1 = X
1 x 12/4 = X
12/4 = X
3 = X
Therefore, the opportunity cost of playing an hour of video games is not reading 3 chapters of a book.
