A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 175,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 8% each year. How many total fish did the company catch over the first 10 years, to the nearest whole number?
The company catches 1,237,275.5 fishes over 10 years.
Given that, a company catches 175000 fishes in a year, the population decreases, the number of fish the company was able to catch decreased by 8% each year.
So, the population in 10 year =
The second year = 175000 × 0.92 = 161000
The third year = 161000 × 0.92 = 148120
The fourth year = 148120 × 0.92 = 136,270.4
The fifth year = 136270.4 × 0.92 = 125368.8
The sixth year = 125268.8 × 0.92 = 115339.3
The seventh year = 115339.3 × 0.92 = 106112.2
The eighth year = 106112.2 × 0.92 = 97623.2
The ninth year = 97623.2 × 0.92 = 89813.3
The tenth year = 89813.3 × 0.92 = 82628.3
The total = 175,000+161000+148120+136,270.4+125368.8+115339.3+106112.2+97623.2+89813.3+82628.3 = 1,237,275.5
Hence, the company catches 1,237,275.5 fishes over 10 years.

Urijah is starting a food cart business. The cost to start the business is $20,000 and the monthly costs are $8,000. He has been earning $8,800 every month in revenue. In how many months will Urijah's business break-even and earn a profit?
He will break even on the 25th month.
How to find the number of month his business will break even?The cost to start the business is $20,000 and the monthly costs are $8,000.
He has been earning $8,800 every month in revenue.
Profit = Selling Price - Cost Price
Therefore,
let
x = number of month
Hence,
selling price = 8800x
cost price = 20000 + 8000(x) = 20,000 + 8000x
Therefore,
profit = 8800x - (20,000 + 8000x)
profit = 8800x - 20000 - 8000x
profit = 8800x - 8000x - 20000
profit = 800x - 20000
Hence,
The month when they will break even is as follows:
8800x = 20,000 + 8000x
20000 = 8800x - 8000x
20000 = 800x
x = 20000 / 800
x = 25
Therefore, he will break even on the 25th month.

Answer:
Hello,
x=-4, y=3
Step-by-step explanation:
14*x+19*y=1 since gcd(182,247)=13
Here is a automatic calculus (using Bezout 's method)
All you have to do is to put in B1 and B2 the right numbers
The values of x and y given that 182x + 247 y = gcd(182, 247) would be x=-4 and y=3.
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
To solve an equation, then the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).
And Solutions to an equation are values of the variables involved in that equation for which the equation is true.
We have given the equation as;
182x + 247 y = gcd(182, 247)
Then we get
14*x+19*y=1
Thus, x=-4 and y=3.
since we have given gcd(182,247)

The monthly cost of using a cell phone is $29.95 plus $0.035 per minute of talk time. An equation to
represent this monthly cost would be:
C = 29.95 + 0.035x, where C represents the monthly cost and x represents the number of minutes used.
How many minutes were used during a month if the cost amounted to $43.53 ?
O 506 minutes
O 426 minutes
O 388 minutes
438 minutes
Answer:
c) 388 minutes
Step-by-step explanation:
Given equation,
→ C = 29.95 + 0.035x
Then the call duration will be,
→ C = 29.95 + 0.035x
→ 43.53 = 29.95 + 0.035x
→ 0.035x = 43.53 - 29.95
→ x = 13.58/0.035
→ [ x = 388 ]
Hence, option (c) is correct.

Prove: Δ M L O ≅ ΔM N O
It is proved that ΔLMN is an isosceles triangle.
What exactly do we mean by a triangle's congruency?Two triangles are said to be congruent if all three corresponding sides are equal and all three corresponding angles are equal in measure.These triangles can be moved, rotated, flipped, and turned to appear identical.If they are repositioned, they will coincide.If two triangles satisfy the five congruence conditions, they are congruent.They are side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), and right angle-hypotenuse-side (RHS).So,
Given:
LM ≅ NMMO bisects ∠L M NTo prove congruency:
MO = MO (Common line)LM = NM = Given∠LM0 = ∠NMO = equal angles (As MO bisects ∠LMN)Therefore, ΔM LO ≅ ΔMNO under SSA congruency.
Since the 2 sides are similar so the angles in front of them will also be similar.So we can say that ΔLMN is an isosceles triangle.Therefore, it is proved that ΔLMN is an isosceles triangle.

The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x^2 + y^2 + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + y^2 - 4y - 16 = 0, then the coefficients are:
D = 0
E = -4
F = -16
If D = -2h and D = 0, then
0 = -2h
h = 0
If E = -2k and E = -4, then

What is the slope of a line perpendicular to the line whose equation is x+4y=16x+4y=16. Fully simplify your answer.
The slope of a line perpendicular to the line of x + 4y = 16 is 4.
What is the slope of a line perpendicular to the line of the given equation?Given the equation of line;
x + 4y = 16
First, rearrange in slope intercept form ( y = mx + b ) by solving for y
x + 4y = 16
Subtract x from both sides
x - x + 4y = 16 - x
4y = -x + 16
Divide each term by 4 and simplify
4y/4 = -x/4 + 16/4
y = -(1/4)x + 4
Using the slope intercept form ( y = mx + b ) to compare.
y = -(1/4)x + 4
Slope m = -(1/4)
Now, the equation of a perpendicular line to y = -(1/4)x + 4 must have a slope that is the negative reciprocal of the original slope.
Hence, m_perpendicular will be;
m_perpendicular = -( 1 / original slope )
m_perpendicular = -( 1 / -(1/4) )
m_perpendicular = -( -4 )
m_perpendicular = 4
