Step-by-step explanation:
Let the amount of money to be paid per month be represented by x. The information given in the question can then be formed into an equation as:
$40 + 12x = $460
From the equation, the amount that'll be paid monthly will be:
$40 + 12x = $460
12x = $460 - $40
12x = $420
x = $420/12
x = $35
The amount paid monthly is $35

Item 10 The endpoints of the directed line segment AB are A(−1, 2) and B(7, 8). Find the coordinates of point P along AB¯¯¯¯¯¯¯¯ so that the ratio of AP to PB is 1 to 3.
Answer:
The coordinates of point P along AB is (1,6.5)
Step-by-step explanation:
We shall use the internal division formula to split AB in the ratio 1 to 3
Mathematically, that would be;
(x,y) = (nx1 + mx2)/m + n , (ny2 + my1)/m + n
m = 1 , n = 3
(x1,y1)= (-1,2)
(x2,y2) = (7,8)
(x,y) = (3(-1) + 1(7)/1+3 , (3(8) + 1(2)/1+3
(x,y) = (-3 + 7)/4, (24 + 2)/4
(x,y) = 4/4 , 26/4
(x,y) = (1, 6.5)

The environment club is having a trash pickup day. There are 130 people signed up to help. For the trash pickup day they will work in 4 people . No more than 4 people can join a group. How many groups are there? Explain how you interpreted the remainder.
Answer: 33 groups
Step-by-step explanation:
Number of people that signed for help = 130 people
Number of people that can join a group = 4.
Number of groups that will be formed will be:
= Number of people that signed for help / Number of people that can join a group
= 130/4
= 32.5
= 33 groups
Since there'll be a remainder of 2 people, they will form a new group making 33 groups.

Expand and simplify (3x-2)^2
Answer:
The answer is: 9x^2 - 12x + 4
Step-by-step explanation:
Perfect square formula: (a - b)^2 = a^2 - 2ab + b^2 ; a = 3x, b = 2
(3x)^2 - 2 * 3x * 2 + 2^2
Simplify:
9x^2 - 12x + 4
The expanded and simplified form of (3x-2)^2 is 9x^2 - 12x + 4.
To expand and simplify (3x-2)^2, we can use the FOIL method. FOIL stands for First, Outer, Inner, Last and is a systematic way to multiply two binomials.
First, let's square the first term:
(3x)² = 9x²
Next, we multiply the outer terms:
(3x)(-2) = -6x
Then, we multiply the inner terms:
(-2)(3x) = -6x
Finally, we square the last term:
(-2)² = 4
Now, let's combine all the terms:
9x² - 6x - 6x + 4
Combining like terms, we have:
9x² - 12x + 4
So, the expanded and simplified form of (3x-2)² is 9x² - 12x + 4.

A circular garden has a radius of 3 meters. What is the area of the garden? Write your answer using π. Show your work.
Answer: 9[tex]\pi[/tex]
Step-by-step explanation:
Sorry the pi sign looks weird. The formula for area of a circle is [tex]a=\pi r^2[/tex], so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.

Speed of Car 2 = 1 mi 2 min
How can you determine by looking at the graph which car is moving at a faster rate? The the line, the the slope.
Car 1 is moving at a speed than car 2.
Answer:
Step-by-step explanation:
The steeper the line (graph), the greater the slope and the greater the speed of that particular car. It is instantly obvious that of the two lines shown, the yellow graph has the greater slope and thus the greater speed.
"The steeper the line, the greater the slope(speed). "Car 1 is moving at a speed than car 2."

3x² - 4x + 6 = p(x - q)² + rSolutionThe least value is at vertex of the parabola ax² + bx + c, with positive a
x and y -coordinates of the vertex is:
x = -b/2a = - (-4)/(2*3) = 2/3y = 3(2/3)² - 4(2/3) + 6 = 3(4/9) - 8/3 + 6 = 4/3 - 8/3 + 6 = 14/3The vertex form is:
y = a(x-h)² + k, where (h, k) is the vertexApplying the same formula to our equation:

Answer:
Step-by-step explanation:
Things to remember,
1). Any point on the graph of a function is represented by [x, f(x)].
2). x-coordinates are the input values on x-axis and f(x) is the output value of the function on y-axis.
A). For x = 2, value of f(2) will be,
f(2) = 4
B). For x = 5, value of f(5) will be,
f(5) = 7
C). Since, 4 < 7
Therefore, f(2) is less than f(5).

What is 60% of 90? *
Answer:
54
Step-by-step explanation:
You can use the short cut 0.6 * 90 ( * is another symbol for the multiplication symbol) this works differently for different numbers. If your percent is one digit, like 3%, you want to change it into the decimal 0.03. The reason why you multiply them together is because “of” is another word for multiply in math terminology.
A rectangle has a length that is 7 inches less that twice it's width. The area of the rectangle is 72 square inches. Write an equation that represents this solution.
Answer: [tex]2x^2-7x=72[/tex] , where x= width of the rectangle ( in inches).
Step-by-step explanation:
Let x= width of the rectangle ( in inches).
Then its length = 2x-7 ( in inches).
Area of rectangle = Length × width
= (2x-7) × (x)
= 2x × x -7 ×x
= 2x²-7x
The area of the rectangle is 72 square inches.
[tex]\Rightarrow\ 2x^2-7x=72[/tex]
Hence, the equation that represents the given situation :
[tex]2x^2-7x=72[/tex]

64.3 x 5 = 321.5
A fruit punch recipe uses 3/4 cup of carbonated water for every 5 cups of fruit juice. Andy has only 4 cups of fruit juice. To make the same fruit punch, how much carbonated water should Andy use?
A) 3/5 cup
B) 3/10 cup
C)2/3 cup
D) 2/5 cup
Answer:
3/5 cup
Step-by-step explanation:
I start by changing the initial fraction of 3/4 into its decimal form of .75 so that it's easier to divide. I then divide it by 5 to find how much carbonated water you should use for a single cup of juice, which is .15 cups. Then, I multiply .15 times 4, which comes out to be .6, or 3/5.
Answer:
3/4 cups of carbonated water is needed by Andy to prepare 5 cups of fruit juice that means that he uses
(3/4)/5 = 3/20 cups of carbon. water for one cup of fruit juice for 4 cups he has to use (3/20)4=12/20
or 3/5 cups of carbonated water or in decimal form 0.6 cups
