The population of a city decreases by 1.6% per year. If this year's population is 320,000, what will next year's population be, to the nearest individual?
Answers
Answer:
314,880
Step-by-step explanation:
If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

The movie club is having a new member sale, so Mindy signs up. The equation -0.4x + 0.05y - 1.25 = 0 relates y, the total cost, and x, the number of months. What is the y-intercept of the line represented by the equation?
Answers
Answer:
Y intercept : ( 0 , 25 )
Step-by-step explanation:
Answer:
(0, 25)Step-by-step explanation:
We need to convert function to slope-intrcept form y=mx+b, where:
-0.4x + 0.05y - 1.25 = 0 {multiply both sides by 20}
-8x + y - 25 = 0 {add (8x+25) to both sides}
y = 8x + 25 ⇒ b = 25
Therefore y-intercept of the line is (0, 25)

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they traveled another 1 4of the total distance. What fraction of the total distance do they have left after
Answers
Answer:
5/12
Step-by-step explanation:
Total distance travelled = 30% + 1/4
To add these numbers, convert 30% to fraction
30% = 1/3
1/3 + 1/4 = 7/12
Remaining distance = 1 - 7/12 = 5/12

3 is a prime number so to split it up you would put 3y in one parentheses and y in the other. at this point it will look like this
(3y )(y )
now, you need to figure out what your signs would be (+ or -) because the second sign in the equation is a negative, your signs would be one + and one - you can decide where to put them until you figure out your two factors. in this case you need to figure out 2 numbers that multiply to 5 and add up to 2. you might think this is impossible, but since the 3 is there, one of those numbers can be multiplied by three. this is your answer:
(3y-1)(y+2)

How do I find the missing side length for 30 - 60 - 90 method as a radical in simplest form?
Answers
Answer:
Step-by-step explanation:
see the image below
Step-by-step explanation:
The side that is adjacent to 60 degree and 90 degree is the shortest side.
If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5
If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.
The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.
If u know the shortest side, just multiply the radical
[tex] \sqrt{3} [/tex]
to the whole number.
If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side
Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.
If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.
If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.
E.x if the second longest side length is
[tex]5 \sqrt{3} [/tex]
Remove the radical so it becomes
[tex]5[/tex]
then multiply it by two to find the hypotunese.
[tex]5 \times 2 = 10[/tex]

Step-by-step explanation:
For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.
110° = 2x + 70°

Carter and his children went into a bakery where they sell cupcakes for $3 each and

and y represents the number of cookies purchased, write and solve a system of
inequalities graphically and determine one possible solution. (I need 2 inequality’s)
Answers
3x + 0.5y = 35
x + y >/= 15
Possible solution: (11, 4)
11 cupcakes, 4 cookies
____________
Cupcakes = x
Cookies = y
Cupcakes are $3 each —> 3x
Cookies are $0.50 each —> 0.5y
$35 to spend: less than or equal to =
3x + 0.5y = 35
Minimum of 15: greater than or equal to >/= 15
x + y >/= 15
____________
3x + 0.5y = 35
x + y >/= 15
Solve second for y:
y >/= 15 - x
Substitute into first:
3x + 0.5(15 - x) = 35
3x + 7.5 - 0.5x = 35
Combine like terms
2.5x + 7.5 = 35
Subtract 7.5
2.5x = 27.5
Divide by 2.5
x is less than or equal to 11
So y is less than or equal to 4
Check:
4 + 11 = 15 :)
3*11 + 0.5*4 = 35
33 + 2 = 35
35 = 35 :)

Answer:

Step-by-step explanation:
just took the quiz
The equation representing the circle A is (x – 4)² + (y + 5)² = 36.
What is circle?A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.
The general equation of circle is given by equation
( x - h )² + ( y - k )² = r²
Where, ( h, k ) is the centre and 'r' is the radius.
As, the circle has a shift of 4 units on the +x axis.
The circle has a shift of the 5 units on the -y axis.
As, the circle has a radius of 6 units from the graph.
So, (h,k) = (4, -5).
Substitute the values of (h,k) in the general equation of the circle.
( x - 4 )² + ( y - (-5) )² = 6²
( x - 4 )² + ( y + 5 )² = 36
Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.
