Answer:

1 1/2 hours

Other ways to show would be; = 1 1/2 hours = 1 .5 hrs = 90 minutes

Step-by-step explanation:

We write out the question 2 1/4 - 3/4 = ?

Then you use the model A below

Next you can add on from the smaller number 3/4 being step 1

And you use model B to find step 2 + step 3 as it reminds you that there is 1/4 in total time being the smallest box out of the sum.

step 1 = 3/4 + 1/4 = 1 = 1/4 is missing in A model box

step 2 = + 1 (to make 2) = 1 is left in B model box

step 3 is + 1/4 is left in B model box

Then add the up = 1/4 + 1 + 1/4 = 1 1/2

Your answers will be model represents 3hrs divided into 6 hours

The function f(t)=t^2+12t-18 represents a parabola. Part A: Rewrite the function in vertex form by completing the square. Show y

ale4655 [162]

The function in vertex form is $f(t) = (t+6)^{2} -54$ (refer to your other post I solved it there).
The general form of quadratic equations in vertex form is $f(x) = a(x-h)^{2} +k$ , where (h, k) is the vertex of the parabola.
Here, a = 1, h = -6 and k = -54
Therefore, the vertex is (-6, -54) and it is a maximum because a = 1 is postive.

What is the slope of the line passing through (1, 2) and (3, 8)? A: slope = 1/7 B: slope = 1/3 C: slope = 3 D: slope = 7

Aliun [14]

Slope = (y2-y1)/(x2-x1) = (8-2)/(3-1) = 6/2 = 3. So the answer is c.
