I really need help on this please help asap if u canmagine you’re working in the kitchen to make cookies for an upcoming bake sale. You need to bake eight dozen total. Your first two batches each take about 30 minutes to mix and bake, but by your third and fourth batches your measuring and mixing have become a lot faster, and you can consistently finish a batch in 20 minutes. Assuming you’ll continue at the same pace, outline the steps it would take to create a word model, create an equation, and then solve the problem to figure out how many hours it will take you to make all eight dozen.

Answers

Answer:

Step-by-step explanation:

To create a word model, equation, and solve the problem of how many hours it will take to make all eight dozen cookies, follow these steps:

**Step 1: Define Variables**

- Let M represent the number of minutes needed to mix and bake each batch.

- Let B represent the number of batches.

**Step 2: Set Up the Word Model**

- In the first two batches, you spend 30 minutes on each batch, so you have 2 batches * 30 minutes/batch = 60 minutes for those batches.

- For the remaining batches (batch 3 and onwards), you spend 20 minutes on each batch.

So, the total time T in minutes for all B batches can be represented as follows:

**T = 60 (minutes) + (B - 2) * 20 (minutes)**

**Step 3: Convert to Hours**

- Since there are 60 minutes in an hour, you need to convert the total time T from minutes to hours. Divide T by 60:

**T (hours) = [60 + (B - 2) * 20] / 60**

**Step 4: Solve for B**

- You want to make a total of 8 dozen (8 x 12) cookies, which is 96 cookies. Each batch makes one dozen (12) cookies.

So, set up an equation for the number of batches needed to make 96 cookies:

**B * 12 = 96**

Now, solve for B:

**B = 96 / 12 = 8 batches**

**Step 5: Substitute B into the Time Equation**

- Now that you know you need 8 batches, substitute this value into the time equation:

T (hours) = [60 + (8 - 2) * 20] / 60

**Step 6: Calculate the Total Time in Hours**

- Simplify and calculate the total time T in hours:

T (hours) = [60 + 6 * 20] / 60

T (hours) = [60 + 120] / 60

T (hours) = 180 / 60

T (hours) = 3 hours

So, it will take you a total of 3 hours to make all eight dozen cookies for the bake sale.

answer: 3 hours have a good day

Tanika took a test that had 20 multiple- choice questions and 10 true/false questions. she got 9/10 of the multiple choice questions correct and she got 4/5 of the true/falsequestions coorect.
how many multiple- choices questions did tanika get correct

Answers

this is a ratio based problem.
knowing that there are 20 mc questions and she got 9/10 of them right, we can solve the problem by getting the equivalent fraction that has the same denominator as the total number of mc questions ( in this case,20)

multiplying 9/10 by 2/2, we get 18/20 and that's the answer

She got 19 answers correct.
