Answer:

  1. SCR (or PPW). 43 more flavors

  2. GLT. 41,976 notebooks

Step-by-step explanation:

1. Conceptual key: SCR

Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...

  37 + x = 80

  x = 80 -37 = 43

Lizzy needs to create 43 more flavors.

__

<em>Additional comment</em>

This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.

_____

2. Conceptual key: GLT

There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.

  (212 boxes)(198 notebooks/box) = 41,976 notebooks

Mark dropped an object from a bridge 400 feet above the ground level with an initial velocity of 0. He knows that the gravitatio
lisabon 2012 [21]

Answer:

The first listed equation is the correct equation to solve

The correct answer is: t = 5 seconds

Step-by-step explanation:

Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :

y(t)=-16\,t^2+ 0 \,t +400

and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:

0=-16\,t^2+ 0 \,t +400\\16\,t^2+0\,t -400=0

which solving for "t" becomes:

16\,t^2-400 =0\\16\,t^2=400\\t^2=\frac{400}{16} \\t^2=25\\t= +/- 5\,\,sec

So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.

That is: t = 5 seconds

Step-by-step explanation:

Area of Rhombus = (1/2)*xy

Where x and y are length of diagonals

Area = (1/2) * 21 * 32 = 21* 16 = 336

Area = 336 m²
