Traders joes sold 7981 bags of tortilla chips recently. If 1178 of these bags were fat free find the percent that were fat free.
lawyer [7]

Answer:

14.76% of tortilla chips bag were fat free.  

Step-by-step explanation:

We are given the following in he question:

Number of bags of tortilla chips sold = 7981

Number of bags hat were fat free = 1178

We have to find the percentage of bags that were fat free.

Percentage:

\dfrac{\text{Number of fat free bags}}{\text{Total number of bags}}\times 100\%\\\\=\dfrac{1178}{7981}\times 100\%\\\\=14.76\%

Thus, 14.76% of tortilla chips bag were fat free.

How to graph transformations of quadratic functions
miskamm [114]

Answer:

Shift "h" units to the right, "k" units up, and reflect over the x or y axis when needed.

Step-by-step explanation:

1) I want to talk about reflections first.

  • Reflections across the x-axis --> y = ax^2, a is the coefficient. if a is negative, then the equation should be reflected across the x-axis. This is known as a vertical reflection.
  • Reflections across the y-axis --> y=a(bx)^2, b is the coefficient. If b is negative, then reflect the equation over the y-axis. There are cases where the reflection across the y-axis does not change anything. But, let's say its y=(x-3)^2... the reflection across the y-axis is different (that equation is: y=(-x-3)^2 )

2) Rigid transformations

  • Horizontal transformations (to the left or right): y=a(bx-h)^2, factor out b from "bx-h" and whatever h equals is the units to the right. If h is a negative number, then you move to the left.
  • Vertical transformations (up and down): y = a(bx-h)^2+k... k is just the units up... if k is negative then we move it down.

Example (check image for visual)

We transform y = x^2 to y = -(-x-3)^2+3 , you move right 3, then reflect across the x-axis, then reflect across y-axis, then move 3 up.

--------------------------------------------------------------------------------------------------------------

Note: In the image, the red line is the original function, the blue one is the transformed function. See if you can follow along with the verbal instructions I gave above.

Solve for x.<br> Greatly appreciate all efforts :)
Lelu [443]

Answer:

x = 11

Step-by-step explanation:

ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.

Angles in an equilateral triangle are all 60°.

Thus, ∠L = 60°.

=> 3x + 27 = 60

=> 3x = 33

=> x = 11
