Answer:
The cost of each cotton candy bag is $4.
Step-by-step explanation:
Consider the provided information.
Let, the vendor has [tex]x[/tex] dollar at the starting of each day.
Let, the cost of each cotton candy bag is [tex]y[/tex].
Now when she sells a total of 12 bags, she has $128.
[tex]x+12y=128[/tex] .....(1)
After she sells a total of 20 bags, she has $160.
[tex]x+20y=160[/tex] ....(2)
Subtract equation 1 from equation 2.
[tex](x+20y)-(x+12y)=160-128[/tex]
[tex]8y=32[/tex]
[tex]y=4[/tex]
Hence, the cost of each cotton candy bag is $4.

How can you write the equation for a linear function if you know only two ordered pairs for the function? Drag tiles tho complete the explanation. Tiles may be used once, more than once, or not at all.
Answer:
Explanation below
Step-by-step explanation:
First determine the slope using (y2-y1)/(x2-x1)
Then set up point slope form and add in an ordered pair for x and y to determine the y intercept: y - y1 = m(x - x1). Solve for y and you'll end up with slope intercept form.
For example: (-2,1), (3,2) find slope and y intercept.
(2-1)/(3-(-2))= 1/5
y-2=.2(x-3)
y=.2x-.6+2
y=.2x+1.4 or y=(x/5)+(7/5)
A bag contains 5 red marbles, 8 white marbles, and 7 blue marbles. You draw 4 marbles out at random, without replacement. What is the probability that all the marbles are red?
Answer: 8/7752
Step-by-step explanation:
Since we are told that the bag contains 5 red marbles, 8 white marbles, and 7 blue marbles. The total number fo marbles would be:
= 5 + 8 + 7
= 20 marbles
If 4 marbles out at random, without replacement, the probability that all the marbles are red would be:
= 5/20 × 4/19 × 3/18 × 2/17
= 1/4 × 4/19 × 1/6 × 2/17
= 8/7752

A rectangular book measures 8 X 10. What is the length of its
diagonal?
Answer:
Length of the diagonals is[tex] \sqrt{ {8}^{2} +{10}^{2} } = \sqrt{64 + 100} = \sqrt{164} =2\sqrt{41}\\ =\boxed{12.8\: units} [/tex]
12.8 units is the right answer.The diagonal length of the rectangular book is 12.8 units.
What is rectangular?A rectangle is "four sided polygon, having all the internal angles is equal to 90 degree. The two sides of each corner is right angles".
According to the question,
The length of rectangle is 8 units and the breadth of rectangle is 10 cm.
To find diagonal of the rectangle: Using Pythagoras theorem a² + b² = c².
c = [tex]\sqrt{a^2 + b^2}[/tex]
= [tex]\sqrt{8^2 + 10^2}[/tex]
= [tex]\sqrt{64 + 100}[/tex]
= [tex]\sqrt{164}[/tex]
= 2[tex]\sqrt{41}[/tex]

Find the solutions to the quadratic. *
y = (x + 13)(x - 21)
Answer:
[tex]\huge\boxed{-13, 21}[/tex]
Step-by-step explanation:
The most common way to solve for the roots of a polynomial is to use the Quadratic formula, which will return us with two values of x that make the equation equal 0.
...however, this form of the equation is already in root form. If we multiplied these two terms, we'd get [tex]x^2 - 8x -273[/tex], and when we factor that, we'd get -13 and 21.
Roots are usually written in the form [tex](x-a)(x-b)[/tex], where the zeroes will be the value of x that makes each binomial equal 0 - aka, the opposite of a and b.
The opposite of 13 is -13, and the opposite of -21 is 21.
Therefore, the solutions of this equation are -13 and 21.

Steve is creating a web page. He starts with a font of 5 9/10 points and decreases it by 1/2. He decreases it again by 6/10 points. Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points. Which is the best estimate of the font's final size?
Answer:
6 3/5 points
Step-by-step explanation:
Steve is creating a web page.
Step 1
He starts with a font of 5 9/10 points and decreases it by 1/2.
Hence: Current font
= 5 9/10 - 1/2
= 5 + ( 9/10 - 1/2)
Lowest common denominator
= 10
= 5 + (9 - 5/10)
= 5 + 4/10
= 5 + 2/5
= 5 2/5 points
Step 2
He decreases it again by 6/10 points.
Current fonts
= 5 2/5 - 6/10
= 5 + ( 2/5 - 6/10)
Lowest common denominator
= 10
= 5 + (4 - 6/10)
= 5 + (-2/10)
= 5 - 1/5
= 4 4/5 points
Step 3
Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points.
New font
= 4 4/5 points + 1 4/5 points
Lowest common denominator = 5
= 4 + 1 + (4/5 + 4/5)
= 5+ ( 4 + 4/5)
= 5 +(8/5)
= 6 3/5 points
The best estimate of the font's final size is 6 3/5 points
Carlo sold his house for P8,000,000. The real-estate agent got a 5% commission from the sales.
From his commission, he has to pay BIR tax and other obligations required for the transfer of ownership
of the property to the buyer. This expense represents 6% of his total commission. How much net
amount will he receive?
Answer:
The net amount received is 7,120,000
Step-by-step explanation:
The computation of the net amount received is shown below:
= Sale value of the house - real agent commission - expenses
= 8,000,000 - 8,000,000 × 5% - 8,000,000 × 6%
= 8,000,000 - 400,000 - 480,000
= 8,000,000 - 880,000
= 7,120,000
Hence, the net amount received is 7,120,000

A. y = 4x
B. 4x - y = -2
C. y = -4x + 6
D. 8x - 2y = 3
E. y = 4x + 9
•
(I think it’s either C, or D, please help I don’t understand)
Answer:
The answer is
[tex]y = - 4x + 6[/tex]
Step-by-step explanation:
Negative reciprocal for the slope.
The equation of the perpendicular line will be y = -4x + d. Then the correct option is C.
What is the equation of a perpendicular line?Let the equation of the line be y = mx + c. Then the equation of the perpendicular line that is perpendicular to the line y = mx + c is given as y = -(1/m) + d. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is given as,
y = (1/4)x - 3
The slope of the line is 1/4. Then the slope of the perpendicular line will be - 4. Then the equation of the line is given as,
y = -4x + d
The equation of the perpendicular line will be y = -4x + d. Then the correct option is C.

20% of 260 students at hill middle school ride a bus to school. how many students ride a bus to school?
Answer:
52 students ride a bus to school
Step-by-step explanation:
Step 1: Our output value is 260.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above $260 = 100%.
Step 4: Similarly, x = 20%.
Step 5: This results in a pair of simple equations:
260 = 100%(1).
x = 20%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
[tex]\frac{260}{x}[/tex] = [tex]\frac{100}{20}[/tex]%
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{260}[/tex] = [tex]\frac{20}{100}[/tex]
⇒x=52$
Therefore, 20% of 260 is 52.
Hope this helps! :)

The number of students who ride a bus is 52.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of students = 260
The number of students who ride a bus.
= 20% of 260
= 1/5 x 260
= 52
Thus,
The number of students who ride a bus is 52.

AC=3x+11
Step-by-step explanation:
ok so AC is Both AB AND BC combined
2x-2+x+13=AC
3x+11=AC
AC=3x+11
Answer:
(2x-2) + (x+13)=6x+2 (take the lengths of AB and BC added together, and put equal to the value of AC)
3x+11 =6x+2 (drop the parenthesis and combine like terms on the left side)
-3x +11 =2 (subtract 6x from both sides and then subtract 11 from both sides)
-3x = -9 (divide both sides by -3 to find what x is)
x=3 (take the x value and plug it into the expression to find the length of AC)
6(3)+2 (multiply)
18+2 (add)
20 (this is the length of AC, and what you put in the box)
