Use pictures or word to explain how you can find the sum for 3+5+2

Response:

first option

Detailed explanation:

The equation expressing a proportional relationship is

y = kx ← with k as the proportional constant

Here k takes the value of 0.7, hence

y = 0.7x ← represents the required equation

Given

= (cross-multiply)

10y = 7x (dividing both sides by 10)

y = x = 0.7 x ← emerges as the needed equation

Answer:

Yes, the cost in dollars and the quantity of yogurt are indeed proportional.

The relationship can be expressed as:

Step-by-step explanation:

1. If varies directly with , it can be represented as:

Here, represents the constant of proportionality.

2. We'll calculate the proportionality constant. Given that and , we have:

3. Thus, the equation becomes:

4. Now, we need to verify proportionality. Substituting , which is the quantity of yogurt purchased by Jonah, we should arrive at $0.48:

5. They are indeed directly proportional.

The attached graph shows the moment when his catch surfaced at (35, 0). Given that it ascends consistently, the graph is linear. We need to establish the starting depth before he reeled it in. Using the equation d=rt, where d represents depth, r is the speed, and t is the time, we can find the distance traveled to reach the surface. Setting up the equation yields: d = 0.1(35). This indicates the catch traveled 3.5 m from a starting point of 3.5 m underwater, ascending at a rate of 0.1 m per second.

The translation rule can be expressed as T -3,1(x,y). The translation can also be indicated as (x,y)➡️(x-3,y+1).

To understand the stacking of cups, start with the height of one cup plus its lip's height. Following that, continue to add the height of each lip until the desired total height is reached. Thus, the total number of cups needed is 19.
