Answer: -280000
Step-by-step explanation: Remove parentheses: (a)=a =12x10 4 - 4x10 5
12x10 4 = 120000
4x10 5=400000
=120000-400000
then subtract the numbers:120000-400000= -280000

A certain city's power company charges their residents for electricity usage on a daily basis. There is a basic charge of 11.6 cents. For each day the first 10 kWh cost 4.59 cents per kWh and any additional kWhs are 9.71 per kWh. (A kWh, or kilowatt-hour, is a unit of energy.)
Complete the following table using the information provided above.
KWh 0 5 10 15 20
cost(dolllar)
KWh 25 30 35 40
cost(dolllar)
Answer:
Table of charges:
KWh 0 5 10 15 20
Basic charge (cents) 11.60 11.60 11.60 11.60 11.60
Charge for first 10 kWh (4.59cents) 0 22.95 45.90 45.90 45.90
Additional usage above 10 kWh 0 0 0 48.55 97.10
(9.71 cents)
Total (cents) 11.60 34.55 57.50 106.05 154.60
cost (dollar) 0.12 0.35 0.58 1.06 1.55
KWh 25 30 35 40
Basic charge (cents) 11.60 11.60 11.60 11.60
Charge for first 10 kWh (4.59cents) 45.90 45.90 45.90 45.90
Additional usage above 10 kWh 145.65 194.20 242.75 291.30
(9.71 cents)
Total (cents) 203.15 251.70 300.25 348.80
cost (dollar) 2.03 2.52 3.00 3.49
Step-by-step explanation:
a) Data:
Basic charge = 11.6 cents (0.116)
Charge for the first 10 kWh = 4.59 cents (0.0459)
Charge for additional usage above 10 kWh = 9.71 cents (0.0971)
b) Each kWh consumed or not attracts the basic charge of 11.6 cents. The first 10 kWh consumed is billed at 4.59 cents, while the additional kWh consumed is charged at 9.71 cents. The charge per consumption is first totaled in cents before being converted to dollars by dividing by 100.

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

find the equation of the straight line passing through the point (0,1) which is perpendicular to the line y=-2x+2
Answer:
y = 1/2x + 1
Step-by-step explanation:
In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.
-2 ⇒ 1/2
Next, we need to substitute the information given into the point-slope formula.
The point-slope formula is:
y - y₁ = m(x - x₁)
y - 1 = 1/2(x - 0)
y - 1 = 1/2x
y = 1/2x + 1
Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
What is the slope of the line

Answer:
12.2
Step-by-step explanation:
7^2 + 10^2 = C^2
49 + 100 = C^2
149 = C^2
√149 = 12.2
C= 12.2

Answer:
55 ft.
Step-by-step explanation:
First find the area of Lot X
67 • 70 = 4,690
Subtract the are of Lot X from the total area
8,375 - 4,690 = 3,685
3,685 is the area of Lot Y
Now divide 3,685 by the length of Lot Y : 67
3,685 ÷ 67 = 55
The width of Lot Y is 55 ft.
Hope this helps!
Suppose that $6500 is placed in an account that pays 17% interest compounded each year. Assume that no withdrawals are made from the account.
Answer: $7,605
Step-by-step explanation:
At the end of 1 years, the amount in the account will be:
= Principal * (1 + rate)^ no. of periods
= 6,500 * (1 + 17%)
= $7,605
A closed-top cylindrical container is to have a volume of 250 in2. 250 , in squared , . What dimensions (radius and height) will minimize the surface area?
Answer:
radius r = 3.414 in
height h = 6.8275 in
Step-by-step explanation:
From the information given:
The volume V of a closed cylindrical container with its surface area can be expressed as follows:
[tex]V = \pi r^2 h[/tex]
[tex]S = 2 \pi rh + 2 \pi r^2[/tex]
Given that Volume V = 250 in²
Then;
[tex]\pi r^2h = 250 \\ \\ h = \dfrac{250}{\pi r^2}[/tex]
We also know that the cylinder contains top and bottom circle and the area is equal to πr²,
Hence, if we incorporate these areas in the total area of the cylinder.
Then;
[tex]S = 2\pi r h + 2 \pi r ^2[/tex]
[tex]S = 2\pi r (\dfrac{250}{\pi r^2}) + 2 \pi r ^2[/tex]
[tex]S = \dfrac{500}{r} + 2 \pi r ^2[/tex]
To find the minimum by determining the radius at which the surface by using the first-order derivative.
[tex]S' = 0[/tex]
[tex]- \dfrac{500}{r^2} + 4 \pi r = 0[/tex]
[tex]r^3 = \dfrac{500 }{4 \pi}[/tex]
[tex]r^3 = 39.789[/tex]
[tex]r =\sqrt[3]{39.789}[/tex]
r = 3.414 in
Using the second-order derivative of S to determine the area is maximum or minimum at the radius, we have:
[tex]S'' = - \dfrac{500(-2)}{r^3}+ 4 \pi[/tex]
[tex]S'' = \dfrac{1000}{r^3}+ 4 \pi[/tex]
Thus, the minimum surface area will be used because the second-derivative shows that the area function is higher than zero.
Thus, from [tex]h = \dfrac{250}{\pi r^2}[/tex]
[tex]h = \dfrac{250}{\pi (3.414) ^2}[/tex]
h = 6.8275 in
What is the volume of the rectangular pyramid shown belown?
9514 1404 393
Answer:
168 cubic inches
Step-by-step explanation:
The formula for the volume of a pyramid is ...
V = (1/3)Bh
where B is the area of the base, and h is the height.
The base is a rectangle, whose are is given by the formula ...
A = LW
A = (8 in)(7 in) = 56 in²
Then the pyramid volume is ...
V = (1/3)(56 in²)(9 in) = 168 in³
The volume of the pyramid is 168 cubic inches.
