In a given year, the population of Metro City is 7420, and the population is decreasing by 152 people per year. The population of Smallville is consistently 1200 less than half of Metro City. Determine how long it will take for Smallville's population to reach 2282.
Which answer provides the correct equation and solution for the situation, where x represents the number of years?
A. The equation is 2282=2(7420−152x)+1200. It will take 45.26 years for the population of Smallville to be 2282 people.
B. The equation is 2282=2(7420−152x)+1200. It will take 45.26 months for the population of Smallville to be 2282 people.
C.The equation is 2282=12(7420−152x)−1200. It will take 3 months for the population of Smallville to be 2282 people.
D. The equation is 2282=12(7420−152x)−1200. It will take 3 years for the population of Smallville to be 2282 people.
Answer:
The correct option is D.
Step-by-step explanation:
Let x denote the years.
The information provided is:
The population of Metro City is 7420.The population is decreasing by 152 people per year.The population of Smallville is consistently 1200 less than half of Metro City.From the provided data derive the equation for the population of Smallville x years after as follows:
[tex]Y = [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]
The population of Smallville is 2282 after x years.
Compute the value of x as follows:
[tex]2282= [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]
[tex]\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3[/tex]
Thus, the time it will take for Smallville's population to reach 2282 is 3 years.
The correct option is D.

Answer:
You are correct, the answer is (y=3)=-2(x-8)
Step-by-step explanation:
For this problem, let's first make the equation of the perpendicular line be in slope intercept form. Add 4y to both sides.
2x=4y+7
Subtract 7.
2x-7=4y
And divide by 4.
y=1/2x7/4
Here, the slope is 1/2, so the slope of the perpendicular line is the negative reciprocal, or -2.
Finally, substitute the given point into the point slope formula to get (y+3)=-2(x-8)

The bright line spectrum of Neon contains a line with the wavelength of 700 nm. What is the
frequency of this light and what color is it?
Answer:
1) The frequency of the light is approximately 4.283 × 10¹⁴ Hz
2) The color of the light is red
Step-by-step explanation:
1) The given parameter;
The wavelength of the line contained in the Neon spectrum, λ = 700 nm = 0.0000007 m = 7.0 × 10⁻⁷ m
The speed of light, v = 299,792,000 m/s
v = f × λ
The frequency, f of the light = v/λ = 299,792,000/(7.0 × 10⁻⁷) ≈ 4.283 × 10¹⁴ Hz
The frequency of the light ≈ 4.283 × 10¹⁴ Hz
2) Given that light with wavelength between 620 - 750 nm constitute red light, we have that the given light with a wavelength of 700 nm is a red light source.

Avery has $70 in a saving account that earns 10% annually. The interest is not compounded. How much will she have in 1 year?
Answer:
I believe the answer will be $77.
Step-by-step explanation:
This is percentages so we need to move the decimal in the 10 percent to the left 2 times. This will leave us with 0.10. We need to multiply this with 70. The equation will be 70x0.10= 7. Finally, you add this answer with the original number(70). Thus, the final answer will be $77.

Do przygotowania jednej porcji gofrow potrzeba 1 i pul szklanki maki pszennej, 1i jedna trzecia szkalanki mleka oraz 0,5 szkalnki oleju pszennego. Szklanka maki wazy 16 dag, szklanka mleka-24 dag, a szklanka oleju-21,5 dag.Ile dekagramow waza lacznie skladniki potrzeba na jedna porcje gofrow?
Odpowiedź:
5,075 dekagramu
Wyjaśnienie krok po kroku:
Biorąc pod uwagę, że:
Na jedną porcję gofra:
mąka pszenna = 1 szklanka
mleko = 1 szklanka
olej pszeniczny = 0,5 szklanki
Waga na filiżankę:
1 szklanka mąki = 16 gramów
Szklanka mleka = 24 g
Dziewczęta oliwy = 21,5 g
Na jedną porcję gofra:
(1 * 16 gramów) + (1 * 24 gramów) + (0,5 * 21,5 gramów)
16 gramów + 24 gramów + 10,75 gramów
= 50,75 grama
Odwołanie :
1 gram = 0,1 dekagramu
50,75 gramów = (50,75 * 0,1)
= 5,075 dekagramu
The median of a set of consecutive odd integers is 138. If the greatest integer in the set is 145, what is the least integer in the set?
Answer:
131
Step-by-step explanation:
Given that:
Median of a consecutive odd integers = 138
Greatest integer In dataset = 145
Least integer in dataset =
Since the integers are consecutive ;
Number of integers to greatest integer value : Greatest integer - median value = 145 - 138 = 7
Hence, 7 integers before the median value should give us the least integer value ;
138 - 7 = 131
CHECK:
131,132,133,134,135,136,137,138,139,140,141,142,143,144,145
Median = (n+1)/2 th term
Median = (15+1)/2 = 8th term = 138
Highest = 145
Least = 131
Answer:
131
