Question

Landscape elementary uses 14 reams of paper every 3 weeks. How many reams of paper do they use each week. round to the nearest hundredth

Answer 1

Jennie is making popcorn. The recipe calls for 12 cup of butter, 3 tablespoons of kernels, and 1 teaspoon of salt. If she uses 10 tablespoons of kernels, how much butter does she need? Round your answer to the nearest hundredth.

Answer 2

Im sorry but that's wrong

Answer 3

Mark and matthew signed up to walk in a 5k walk/run race. they think it will take them 60 minutes to complete the race but they do it in 53 minutes what is the percent error. round to the nearest tenth

Answer 4

To find out how many reams of paper Landscape Elementary uses each week, you can divide the total amount of paper they use in three weeks by the number of weeks.

Given that they use 14 reams of paper every 3 weeks, the calculation is:

\[
\text{Reams per week} = \frac{14 \text{ reams}}{3 \text{ weeks}} \approx 4.66667 \text{ reams/week}
\]

Rounding to the nearest hundredth, you get:

\[
\text{Reams per week} \approx 4.67 \text{ reams/week}
\]

So, Landscape Elementary uses approximately **4.67 reams of paper each week**.

Answer 5

To find out how much butter Jennie needs when she uses 10 tablespoons of kernels, we first need to establish the ratio of butter to kernels in the original recipe.

The original recipe calls for:

- 12 cups of butter
- 3 tablespoons of kernels

Now, we can calculate the amount of butter needed per tablespoon of kernels:

\[
\text{Butter per tablespoon of kernels} = \frac{12 \text{ cups of butter}}{3 \text{ tablespoons of kernels}} = 4 \text{ cups of butter per tablespoon of kernels}
\]

Now we can use this ratio to calculate how much butter Jennie will need for 10 tablespoons of kernels:

\[
\text{Butter needed} = 10 \text{ tablespoons of kernels} \times 4 \text{ cups of butter per tablespoon of kernels} = 40 \text{ cups of butter}
\]

Therefore, Jennie needs **40 cups of butter** when she uses 10 tablespoons of kernels.

Since the question specifies rounding to the nearest hundredth, it's worth noting that since the answer is a whole number, it would simply remain **40.00 cups**.

Answer 6

My apologies for the oversight. Let's go through the calculation step-by-step again.

1. **Original Recipe:**
- Butter: 12 cups
- Kernels: 3 tablespoons

2. **Calculate the ratio of butter to kernels:**
- For every 3 tablespoons of kernels, she uses 12 cups of butter.

3. **Determine how many cups of butter are needed per tablespoon of kernels:**
\[
\text{Butter per tablespoon} = \frac{12 \text{ cups}}{3 \text{ tablespoons}} = 4 \text{ cups of butter per tablespoon of kernels}
\]

4. **Now find the amount of butter needed for 10 tablespoons of kernels:**
\[
\text{Butter needed} = 10 \text{ tablespoons of kernels} \times 4 \text{ cups of butter per tablespoon} = 40 \text{ cups of butter}
\]

Apologies for not simplifying this calculation in my original response. It appears the calculation is indeed correct for the specified amount. If the recipe is followed proportionally with 10 tablespoons of kernels, it consistently yields **40 cups of butter**.

If you meant to convey something else or if there’s a specific component of the problem I misinterpreted, please let me know!

Answer 7

To calculate the percent error, you can use the following formula:

\[
\text{Percent Error} = \left( \frac{\text{Absolute Error}}{\text{Expected Value}} \right) \times 100
\]

1. **Determine the expected value (time they thought it would take)**:
Expected value = 60 minutes

2. **Determine the actual value (time it actually took)**:
Actual value = 53 minutes

3. **Calculate the absolute error**:
Absolute error = |Expected value - Actual value|
\[
\text{Absolute Error} = |60 - 53| = 7 \text{ minutes}
\]

4. **Now plug the values into the percent error formula**:
\[
\text{Percent Error} = \left( \frac{7 \text{ minutes}}{60 \text{ minutes}} \right) \times 100
\]

5. **Calculate the percent error**:
\[
\text{Percent Error} = \left( \frac{7}{60} \right) \times 100 \approx 11.6667
\]

6. **Round to the nearest tenth**:
\[
\text{Percent Error} \approx 11.7\%
\]

Thus, the percent error is approximately **11.7%**.
