You are filling piñatas for your sister's birthday party. The list shows the gifts you are putting into the piñatas. You want identical groups of gifts in each piñata with no gifts left over. What is the greatest number of piñatas you can make?
Answer:
The greatest number of piñatas you can make with the gifts is:
6 piñatas.Step-by-step explanation:
To identify the greatest number of piñatas, you must think in a number that can divide another and obtain a whole number with this:
182442Bigger the number, greater the number of piñatas, in this case, you can see the numbers given can be divided into four numbers obtaining a whole number: 1, 2, 3, and 6. Remember that the best number is the greatest, in this case, number six. Now you proceed to divide the numbers into 6:
[tex]\frac{18}{6}= 3[/tex][tex]\frac{24}{6}= 4[/tex] [tex]\frac{42}{6}=7[/tex]Taking into account the values obtained, you can see that each piñata would have: 3 bottles of nail polish, 4 pairs of earrings, and 7 lollipops.

A
Find an equation of the circle and sketch it if it has: Tangent to x-axis, r=4, contains (–5,8)
B
Find an equation of the circle and sketch it if it has:
Diameter endpoints (2, 5) and (0, 3)
C
Find an equation of the circle and sketch it if it has:
Center on x=3, tangent y-axis at (0, 5)
Answer:
A. [tex](x+5)^2+(y-4)^2=16[/tex]
B. [tex](x-1)^2+(y-4)^2=2\\[/tex]
C. [tex]$\left(x-3\right)^2+\left(y-5\right)^2=9$[/tex]
Step-by-Step Explanation:
A. Tangent to x-axis, r=4, contains (-5,8)
The equation of a circle is this: [tex](x-h)^2+(y-k)^2=r^2\\[/tex]
Therefore, we know that our equation will be: [tex](x-h)^2+(y-k)^2=4^2=16[/tex]
Because the circle is tangent to the x-axis, the point (-5,8) will be the top of the circle.
Therefore, the center is (-5,4), where -5=h and 4=k.
The answer is [tex](x+5)^2+(y-4)^2=16[/tex]
B. Diameter endpoints (2,5) and (0,3)
To solve for the diameter, we can use this equation: [tex]d=\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2 }[/tex]
[tex]d=\sqrt{(2-0)^2+(5-3)^2 }\\\\d=\sqrt{2^2+2^2}=\sqrt{4+4} =\sqrt{8}= 2\sqrt{2}[/tex]
Because the radius is half of the diameter, [tex]r=\sqrt{2}[/tex]
Therefore, we know that our equation will be: [tex](x-h)^2+(y-k)^2=(\sqrt{2}) ^2=2[/tex]
Then, we can decipher that h=1, as the midpoint of 0 and 2 is 1, and k=4, as the midpoint of 3 and 5 is 4.
The answer is [tex](x-1)^2+(y-4)^2=2[/tex]
C. Center on x=3, tangent to y-axis at (0,5)
We can see that the center is (3,5). Therefore, the equation is [tex](x-3)^2+(y-5)^2=r^2\\[/tex]
To solve for r, we can substitute the point (0,5) into the equation.
[tex](0-3)^2+(5-5)^2=r^2\\(-3)^2+(0)^2=r^2\\r^2=9[/tex]
The answer is [tex](x-3)^2+(y-5)^2=9[/tex]

Find the slopes of the linear functions.
y = -2x + 7
The slope of the line given by the linear equation is
ty
The slope of the line shown in the graph is
4
-8
4
Answer:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Step-by-step explanation:
The line equation, y = -2x + 7 is written in the slope-intercept form, which is represented by the formula, y = mx + b.
m is the slope, while b is the y-intercept.
Therefore, the slope of the line of the linear equation, y = -2x + 7 is -2.
Find the slope of the line shown in the graph using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].
Use the coordinates of any two points on the line. Let's use (0, 5) and (5, 0)
Let,
[tex] (0, 5) = (x_1, y_1) [/tex]
[tex] (5, 0) = (x_2, y_2) [/tex]
[tex] m = \frac{0 - 5}{5 - 0} = \frac{-5}{5} = -1 [/tex]
Therefore:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Solve: -4 (x + 6) + 2 ( x -2) Show your work
Answer:
-2x - 28
Step-by-step explanation:
-4(x+6) +2 (x-2) Distribute the -4 to (x+6) and the 2 to (x-2):
-4x - 24 + 2x - 4 Combine like terms -4 + 2x and -24-4:
-2x - 28
Hope this helped :)
Answer:
Please see explanation.
Step-by-step explanation:
-4(x+6) + 2(x-2) First, distribute the -4 to x+6
-4x - 24 + 2(x-2) Now distribute the 2 into x-2
-4x - 24 + 2x - 4 Combine like terms
-4x + 2x - 24 - 4
-2x - 28 This might be your answer but if you are looking for what x is equal to then keep following along.
If you are solving for x then most likely the equation says that it is equal to zero
-2x - 28 = 0 Add 28 to both sides
-2x = 28 divide both sides by -2
x = -14

Anthony has saved $15 of the $140 he needs to purchase a new bicycle. He plans to save $15 each week w, until he has enough money to buy the bicycle. Write an equation to find the number of weeks it will take Anthony to save enough money to buy the bicycle.
Answer:
(140-15)÷15=W
Step-by-step explanation:
140-15=125
125 still needed. divide that by the amount that will be saved each week which is 15 a week and you get 8.3. If they want an actual answer you would say 9 weeks because if you only did 8 Anthony would be short $5 so hed have to wait an additional week to have enough to cover the purchase. So thats why the answer would be 9

Range represents the y-values from the lowest (furthest down) to the highest (furthest up).
Interval notation: If a value is included (closed dot), use a bracket [ ]
If a value is NOT included (open dot), use a parenthesis ( )
Note that ± ∞ is never included.
1. Domain: smallest x-value is -4 (included). biggest x-value is 3 (included)
Range: lowest y-value is 2 (included). highest y-value is 5 (included)
D: x = [-4, 3] R: y = [2, 5]
2. Domain: smallest x-value is -∞ (←). biggest x-value is 2 (included)
Range: lowest y-value is 2 (included). highest y-value is ∞ (↑)
D: x = (-∞, 2] R: y = [2, ∞)
3. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)
Range: lowest y-value is -∞ (↓). highest y-value is ∞ (↑)
D: x = (-∞, ∞) R: y = (-∞, ∞)

1. Contaminated water is subjected to a cleaning process. The concentration of the pollutants is initially 5 mg per liter of water. If the cleaning process can reduce the pollutant by 10% each hour, define a function that can represent the concentration of pollutants in the water in terms of the number of hours that the cleaning process has taken place.
Answer:
[tex]C(t)=5\cdot(0.9)^t[/tex]
Step-by-step explanation:
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The concentration of the pollutants starts at Co=5 mg/lt. We also know the pollutant reduces its concentration by 10% each hour. This gives us a value of r = 10% / 100 = 0.1
Substituting into the general equation:
[tex]C(t)=5\cdot(1-0.1)^t[/tex]
Operating:
[tex]\boxed{C(t)=5\cdot(0.9)^t}[/tex]
y(n) = 5(0.9)ⁿ
To answer this, we will make use of the exponential decaying function which is given by;y(n) = a(1 - b)ⁿ
where;
y is the final amount at time n,
a is the original amount
b is the decay factor
x is the amount of time that has passed.
We are told that the initial concentration of the pollutants is 5 mg/LThus;
a = 5 mg/L.
We are told that the pollutant reduces its concentration by 10% each hour. Thus; b= 10%
b = 0.1
Therefore Plugging in the relevant values into y(n) = a(1 - b)ⁿ, we have;y(n) = 5(1 - 0.1)ⁿ
y(n) = 5(0.9)ⁿ
