Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each??? don't spam ❤ |

Answer» Answer: 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds. 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds.= 15/4 ÷ 4 pounds. 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds.= 15/4 ÷ 4 pounds.= 15/4 × 1/4 pounds. 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds.= 15/4 ÷ 4 pounds.= 15/4 × 1/4 pounds.= 15/16 pounds. 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds.= 15/4 ÷ 4 pounds.= 15/4 × 1/4 pounds.= 15/16 pounds.Now we know that, 1 pound = 16 ounces. 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds.= 15/4 ÷ 4 pounds.= 15/4 × 1/4 pounds.= 15/16 pounds.Now we know that, 1 pound = 16 ounces.Therefore, 15/16 pounds = 15/16 × 16 ounces. 33/4 ÷ 4 pounds.= (4 × 3 + 3)/4 ÷ 4 pounds.= 15/4 ÷ 4 pounds.= 15/4 × 1/4 pounds.= 15/16 pounds.Now we know that, 1 pound = 16 ounces.Therefore, 15/16 pounds = 15/16 × 16 ounces.= 15 ounces Step-by-step explanation: VERIFIED Answer ❤ |

Three students gave an improvement test. Ajay scored 3060in hisfirst test and 3560 in improvement test. Sonu scored 4270in his first testand in 5060 in improvement test. Manish scored 5060in his first test and4250 in improvement test.I. What fraction of improvement did Manish made?II. Which student improved themost? |

Answer» Given :- Three students gave an improvement TEST. Ajay scored 30/60 in his first test and 35/60 in improvement test. Sonu scored 42/70 in his first test and 50/60 in improvement test. Manish scored 50/60 in his first test and 42/50 in improvement test. Solution :- → Ajay scored in first test = 30/60 → Ajay scored in improvement test = 35/60 so, → Ajay improved score = (35/60) - (30/60) = (5/60) = (1/12) similarly, → Sonu scored in first test = 42/70 → Sonu scored in improvement test = 50/60 so, → Sonu improved score = (50/60) - (42/70) = (350 - 252/420) = (98/420) = (7/30) and, → Manish scored in first test = 50/60 → Manish scored in improvement test = 42/50 so, → Manish improved score = (42/50) - (50/60) = (252 - 250/300) = (2/300) = (1/150) (Ans.i) now, → (1/12), (7/30), (1/150) → (25, 70, 2)/300 since, → 70 > 25 > 2 therefore, → (7/30) > (1/12) > (1/150) hence, Sonu improved the most .Learn more :- the average age of 30 students is 9 years if the age of their TEACHER is included it becomes 10 years ago the age of the...

Find the value of 3 root 12/3 root 3 |
|
Answer» Answer: MENU MyTutor logo LOG IN Answers>Maths>GCSE>Article Work out the value of (√12 + √3) squared. Assume square roots are positive. (√12 + √3) squared is just (√12 + √3) mulitipled by itself, so we can rewrite this as (√12 + √3)*(√12 + √3) Now we expandthe brackets. We can mulitply out the brackets using the FOIL method. (First Outside Inside Last) We multiply the First terms TOGETHER. The first term in both brackets in this case is √12. The square root of 12 multiplied by the square root of 12 is simply 12. Now we multiply the Outside terms together. These are the first term in the first BRACKET and the last term in the last bracket. In this case this is √12 multiplied by √3. The product property of square roots states that √a multiplied by √b is equal to √(AB). So, √12 multiplied by √3 is equal to √(12 *3) which is √36. The square root of 36 is equal to 6 (for this question we can assume the positive value for square roots). Now we mulitply the Inside terms together. These are the last term in the first bracket and the first term in the last bracket. In this case this is √3 multiplied by √12. This is the same as the previous step, again giving us a value of 6. Then we multiply the Last terms together. The last term in both brackets in this case is √3. The square root of 3 multiplied by the square root of 3 is 3. Finally, we ADD up all of the values we calculated above. 12 + 6 + 6 + 3 = 27 So our answer is 27. Remember: If we had subtraction within either of the brackets then we would have to be careful with signs, as we COULD end up with negative numbers, so would have to be remember to include any minus signs when adding final terms. |
