the length of a door is 1.8 feet longer than it's width, and it's front area is 1504.6 square feet. find the width and height of the door
Answer:
width: 37.9 ft
height: 39.7 ft
Step-by-step explanation:
Sometimes it is easier to work these problems by finding the average of the length and width. If that value is x, then the length is x+0.9, and the width is x-0.9. The area is ...
A = LW
1504.6 = (x +0.9)(x -0.9) = x^2 -0.81
1505.41 = x^2
x = √1505.41 ≈ 38.7996
width = x -0.9 = 38.8 -0.9 = 37.9
height = 38.8 +0.9 = 39.7
The width of the door is approximately 37.9 ft; the height is about 39.7 ft.
Aline that includes the point 5. 10) has a siope of 1. What is its equation in siope-intercept
te your answer using integers, proper fractions, and improper fractions in simplest for
Step-by-step explanation:
a lot of typos in the problem description.
if I understand correctly, the line contains the point (5, 10) and has a slope of 1.
and we need to give the line equation in slope-intercept form.
that means it has to look like
y = ax + b
a is the slope and b is the y-intercept (hence the name of the form).
we know a = 1.
we can use use the point-slope form to start and then transform it into the slope-intercept form.
point-slope means
y - y1 = a(x - x1)
a is again the slope, and (x1, y1) is a point on the line.
so,
y - 10 = 1(x - 5) = x - 5
now we transform it (adding 10 on both sides)
y = x + 5
and that's it.
snowboard is advertised to be 60% of the original price. If the sale price is $180, use a double number line determine the original price.
Step-by-step explanation:
60% of original price X = $180
60/100 × X = $180
60X/100= $180( cross multiply)
60X= 18000
X= 18000÷60
X= $300

3. West Fremont is a community consisting of 3,000 homes. A small coal-burning power plant currently supplies electricity for the town. The capacity of the power plant is 12 megawatts
(MW) and the average household consumes 8,000 kilowatt hours (kWh) of electrical energy each year. The price paid to the electric utility by West Fremont residents for this energy is $0.10 per kWh. The town leaders are considering a plan, the West Fremont Wind Project (WFWP), to generate their own electricity using 10 wind turbines that would be located on the wooded ridges surrounds the town. Each wind turbine would have a capacity of 1.2 MW and each would cost the town $3 million to purchase, finance, and operate for 25 years.
(a) Assuming that the existing power plant can operate at full capacity for 8,000 hrs/yr, how many kWh of electricity can be produced by the plant in a year?
(b) At the current rate of electrical energy use per household, how many kWh of electrical energy does the community consume in one year?
(c) Assuming that the electrical energy needs of the community do not change during the 25-year lifetime of the wind turbines, what would be the cost to the community of the electricity supplied by the WFEP over 25 years? Express your answer in dollars/kWh.
Power is the rate of doing work, and the power of the generating plant or
turbine and the duration of generation, gives the energy generated.
The correct responses are;
(a) 96 × 10⁶ kWh(b) 24 × 10⁶ kWh(c) 0.05 dollars/kWhReasons:
Number of homes in the town = 3,000 homes
The given capacity of the power plant = 12 MW = 12,000 kW
Power consumed by a household = 8,000 kWh per year
The price for electrical energy = $0.10 per kWh
Number of wind turbines = 10
WFWP = The West Fremont Wind Project
Capacity of each wind turbine = 1.2 MW
Cost of each wind turbine for 25 years = $3 million
(a) Number of hours of operation of the power plant = 8,000 hrs/yr
Required:
The amount of kWh of electricity produced in a year by the plant.
Solution:
The energy produced = Power × Time
∴ The energy produced = 12,000 kW × 8000 hr = 96,000,000 kWh
Therefore;
The energy produced by the plant in a year, E = 96 × 10⁶ kWh
(b) Energy consumed = Energy consumed per home × Number of homes
Therefore;
Energy consumed = 8,000 kWh/home × 3,000 homes = 24,000,000 kWh
The energy the community consumes in one year = 24 × 10⁶ kWh
(c) The cost per kWh = $0.10
The cost, C, of the energy per year is therefore
C = 24,000,000 kWh × $0.10/kWh = $2,400,000
The cost for 25 years = 25 × C = 25 × $2,400,000 = $60,000,000
The number of wind turbines = 10
Cost per wind turbine = $3 million
Total cost to operate the 10 wind turbine = $3 million × 10 = $30 million
Energy consumed = 24,000,000 kWh
Therefore;
24,000,000 kWh × 25 = $30 million
[tex]\displaystyle 1 \ kWh = \frac{\$ 30 \ million}{25 \times 24,000,000 \ kWh} = \mathbf{\$0.05/kWh}[/tex]
The cost to the community of the electricity supplied by WFWP over 25 years is $0.05/kWh.

the product of two factors is 4200.if one of the factors is 60.what is the other factor?
Answer:
Other factor is 70
Step-by-step explanation:
Let,
Other factor = x
Then,
x × 60 = 4200
x = 4200/60
x = 420/6
x = 70
∴Another factor is 70.
