What’s the Error?

Question 13. The Redwood National Park is home to some of the largest trees in the world. Hyperion is the tallest tree in the park, with a height of approximately 379 feet. Tom wants to find the height of the tree in yards. Tom converted the height this way : 3 feet = 1 yard conversion factor: \(\frac{3 \mathrm{ft}}{1 \mathrm{yd}}\) \(\frac{379 \mathrm{ft}}{1} \times \frac{3 \mathrm{ft}}{1 \mathrm{yd}}\) = 1,137 yd Find and describe Tom’s error. Show how to correctly convert from 379 feet to yards. Explain how you knew Tom’s answer was incorrect. Type below: ____________

Answer: conversion factor: 3ft1yd 379ft1 × 3ft1yd = 1,137 yd We need to divide the 379 feet with 3 to get the height of the Hyperion tree, but tom multiplies the 379 with 3 and that is the error part 1 yard = 3 feet 1 feet = 1/3 yards So, 379 feet = 379/3 yards = 126.3 yards So, the height of the Hyperion tree is 126.3 yards

Question 16. Jeffrey is loading cases of bottled water onto a freight elevator. There are 24 one-pint bottles in each case. The maximum weight that the elevator can carry is 1,000 pounds. If 1 gallon of water weighs 8.35 pounds, what is the maximum number of full cases Jeffrey can load onto the elevator? a. What do you need to find? Type below: ____________

Answer: the maximum number of full cases Jeffrey can load onto the elevator

Question 16. b. How can you find the weight of 1 case of bottled water? What is the weight? Type below: ____________

Answer: Using one-pint bottles and 1 gallon of water weighs 8.35 pounds information

Question 16. c. How can you find the number of cases that Jeffrey can load onto the elevator? Type below: ____________

Answer: 1 US liquid pint is equivalent to 0.125 US liquid gallons. So, 24 one-pint bottles is equivalent to (24 × 0.125) =3 gallons. Therefore, one full case of bottled water is equal to 3 gallons. Now, 1 gallon is equal to 8.35 pounds And hence, 3 gallons is equal to (8.35 × 3) = 25.05 pounds.

Question 16. d. What is the maximum number of full cases Jeffrey can load onto the elevator? _______ cases

Answer: 39 cases

Explanation: 1 US liquid pint is equivalent to 0.125 US liquid gallons. So, 24 one-pint bottles is equivalent to (24 × 0.125) =3 gallons. Therefore, one full case of bottled water is equal to 3 gallons. Now, 1 gallon is equal to 8.35 pounds And hence, 3 gallons is equal to (8.35 × 3) = 25.05 pounds. If the maximum weight that the elevator can carry is 1000 pounds, then the maximum number of cases of bottled water that the elevator can carry is ≈ 39 We can not take the number as 40, because then the total weight will become more than 1000 pounds which is not allowed.

Question 17. Monica put 1 liter, 1 deciliter, 1 centiliter, and 1 milliliter of water into a bowl. How many milliliters of water did she put in the bowl? _______ milliliters

Answer: 1111 milliliters

Explanation: Monica put 1 liter, 1 deciliter, 1 centiliter, and 1 milliliter of water into a bowl 1 liter = 1000 milliliters 1 liter = 10 deciliters so, 10 deciliters = 1000 milliliters then, 1 deciliter = 100 milliliters 1 liter = 100 centiliters So, 100 centiliters = 1000 milliliters Then, 1 centiliter = 10 milliliters 1 liter + 1 deciliter + 1 centiliter + 1 milliliter = 1000 milliliters + 100 milliliters + 10 milliliters + 1 milliliter = 1111 milliliters Monica filled the bowl with 1111 milliliters of water

VERY USEFUL APP!!! - Sherry ⚡️

I’m not failing my grades as I used to be and thank god I found this app. I been failing my tests but now that I found this app I’m passing all my classes! Tysm to the owner to whoever made this :) gladly I rate this a 5 star app it’s useful for people who have low grades or are failing classes. I use this app with my brother and he isn’t getting b’s anymore he’s getting straight A’s. Ty ty ty ty for this app to be made! Share all the love with this app 💓💓

Developer Response ,

Thank you for taking the time to submit your feedback! We value our users’ loyalty greatly and our team is always dedicated to improving the quality of your experience.

This app is horrible. I expected to be accurate it wasn’t. For starters, I downloaded this app so it could help me with my math. I wanted to be sure is was accurate so I took a picture of a old math problem and see if it would work. I looked at the answer key with the answer. For example, let’s say the answer from this app was 26. The answer key said it was 78. It was confusing so it has a respond feature and I typed this is not accurate. Then it gave me a complete different answer and the new answer was 12! I was puzzled. So I solved the question on my own and the answer key was correct. I took a another photo and the same answer, 12. I searched up on google the problem and it was 78. I paid $6.99 for this trash.

We apologize for any issues you've encountered while using our app. Our team is currently working on enhancing the app, so please keep an eye out for the upcoming update.

My honest opinion

It’s a good app, but most of the time you have to re-take a photo, or the answer is wrong. 40% of the time the app doesn’t want to work, or closes on me when I’m using it. It’s a good app for easy, quick, answers.. but not so much big ones. I do like that it works for questions with pictures.. and it has a specific mode for math questions. Would I recommend you download it.. yes. It is a good app, maybe just needs a couple of updates/bug fixes.
