Para festeja su cumpleaños,Nancy compró 15 paquetes de pizzetas. Si cocinó 288 pizzetas, cuántos paquetes completos le quedaron?
Answer:
Nancy consumió 12 paquetes de pizzetas y le quedaron 3 paquetes completos.
Step-by-step explanation:
En primer lugar, debemos descomponer el número total de pizzas como una multiplicación de números primos. Al realizar la descomposición factorial tenemos que:
[tex]288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3[/tex]
Entonces, los familia de divisores de 288 es el siguiente conjunto:
[tex]D_{288} = \{2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144 \}[/tex]
Si tanto la cantidad de paquetes de pizzetas y la cantidad cocinada de pizzetas son números enteros y positivos, siendo la última mucho mayor. Entonces, la cantidad de pizzetas debe ser un número entero y la cantidad de paquetes gastados menor a la cantidad de paquetes comprados y el número entero más cercano a esa cantidad. Entonces, concluimos que Nancy se gastó 12 paquetes de pizzetas, quedándole 3 paquetes completos.

Answer:
x = 3.5
Step-by-step explanation:
Each value is multiplied by 1.5 so 7 times 1.5 is 10.5
10.5/3 = 3.5
Answer:
1.5
Step-by-step explanation:
To find the value of x that makes triangle DEF similar to XYZ, we have to find the scale. To do this find 2 similar sides. I chose 7.5 from XYZ and 5 from DEF. Divide 7.5 by 5 to get 1.5. 1.5 is our scale so this means we will insert 1.5 for x and get 4.5 as our answer.
Ratio, proportion and percent unit 4 homework 3 wages hours 1 wage is $9.50 2 $19.00 3 $28.50 4 $38.00
Answer:
(a) The complete table
[tex]\begin{array}{cccccc}Hours & {1} & {2} & {3} & {4} &{5}\ \\ {Amount} & {\$9.50} & {\$19.00} & {\$28.50} & {\$38.00} & {\$47.50} \ \end{array}[/tex]
(b) $38.00
(c) 3 hours
Step-by-step explanation:
Given
[tex]Earnings = \$9.50[/tex] per hour
See attachment for complete question;
Solving (a): Complete the table
To complete the table, we simply multiply the earnings by the number of hours.
So, we have:
[tex]Hours = 2 \to Earnings = \$9.50 * 2 = \$19.00[/tex]
[tex]Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50[/tex]
[tex]Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00[/tex]
[tex]Hours = 5 \to Earnings = \$9.50 * 5 = \$47.50[/tex]
Solving (b): Earnings, if Megan works for 4 hours
In (a) above, we have:
[tex]Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00[/tex]
This implies that Megan will earn $38.00
Solving (c): Hours to earn $28.50
In (a) above, we have:
[tex]Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50[/tex]
This implies that Megan will work for 3 hours to earn $28.50

What is the y-intercept of the line that goes through the points (5, -8) and (9, -12)
Answer:
-3
Step-by-step explanation:
Given the points, we can see that as x increases by 4, y decreases by 4, which means the slope is -1. Working backwards from (5, -8), we can decrease x by 5 (and thus increase y by 5, since we're subtracting a negative) and add that to -8 to find the y-intercept = -3
change from quadratic to vertex form.
Answer:
Factor out 1/3 because its a coefficient of x².
Why?
In order to proceed and complete the square... We need the coefficient of x² to be 1 and luckily for us.... Factoring 1/3 even makes everything easier
y=1/3[ x² + 20x + 97]
Using completing square on the function inside the bracket
x² + 20x + 10² + 97 – 10²
We have it to be( x + 10)² - 3]
y = 1/3[ (x +10)² - 3]
This is our Vertex Form... y=1/3[(x + 10)² - 3]
v(-10,-3).

A quadratic function y=f(x) is plotted on a graph and the vertex of the resulting parabola is (−5,−3). What is the vertex of the function defined as g(x)=−f(x)+3?
Answer:
(-5 , 6)
Step-by-step explanation:
f(x) = (x - (-5))² - 3 ... vertex (h , k) : (-5 , -3) y = (x-h)² + k
g(x) = -f(x) + 3 = -((x+5)² - 3) + 3 = -(x + 5)² + 6
vertex of g(x) is : (-5 , 6)
Elizabeth buys 50 meters of ribbon to make bows for the cheer squad. Each bow uses 1.3 meters of ribbon. How many bows can Elizabeth make? *
Answer:
38 bows
Step-by-step explanation:
50 ÷ 1.3 ≡ 38 6/13
38 × 1.3 = 49.4
Since you cant make 6/13 of a ribbon, Elizabeth would be able to make 38 bows.

Width=
WILL GIVE BRAINLIEST + 5 star
Answer:
x = 20
Length = 20ft
Width = 12ft
Step-by-step explanation:
A = 240
x^2 - 8x = 240
x^2 - 8x - 240 = 0
x^2 - 20x + 12x - 240 = 0
x(x-20) + 12(x-20) = 0
(x+12)(x-20) = 0
x = 20
x = -12 (which we discard since x is a length)
So the dimensions are 20ft and 20-8 = 12ft

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 6x + 10
(a)
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = x² + 2(3)x + 9 - 9 + 10
y = (x + 3)² + 1 ← in vertex form
(b)
Since a = 1 > 0 then vertex is a minimum
(c)
(h, k ) = (- 3, 1 ) ← coordinates of vertex

The cost of a shirt went from $10 to $12. What is the percent of change?
Answer:
%120
Step-by-step explanation:
The original cost was $10 then it went to $12, so 100 percent representing the 10, then with 2 dollars left it is 20 percent. You can check by multiplying 1.2 by 10.
Hope I helped :]
Answer:
20.00%
Step-by-step explanation:
$12-$10=$2

Answer:
[tex]6(x-10)(x+9)[/tex]
Step-by-step explanation:
First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression [tex]6(x^{2} +x-90)[/tex]. Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, [tex]6(x-10)(x+9)[/tex].
