Answer :
Yerald's new weight is 87.250 kg, Jason is serving approximately 357 grams of turkey per person, Young-Mi paid $3.01 for onions, the standard antibiotic dose for a 140-lb woman is 22.4 cc, and the label printer will take 13.6 seconds to print 72 pages of labels.
Yerald weighed 92 kg and then lost 4 kg 750 g. To find his current weight, we convert 750 g to kg, which is 0.750 kg. Subtracting this from his original weight, we get 92 kg - (4 kg + 0.750 kg) = 87.250 kg.
For Jason serving a 10 kg turkey to 28 people, we calculate the amount per person by dividing 10 kg by 28. Since 1 kg is 1000 grams, 10 kg is 10000 grams. Dividing this by 28, each person gets approximately 357 grams of turkey, when rounded to the nearest whole gram.
Young-Mi bought 2 kg 20 g of onions at $1.49 per kilogram. Converting 20 g to kg gives us 0.020 kg. The total weight in kg is 2 kg + 0.020 kg = 2.020 kg. Multiplying this weight by the price per kg, we have 2.020 kg x $1.49/kg = $3.01, rounded to the nearest cent.
To find the standard dose of an antibiotic for a 140-lb woman, we set up a proportion with the given dose rate. If 4 cc is for 25 lbs, then X cc is for 140 lbs. Cross-multiplying, we get X = 4 cc x (140 lbs)/(25 lbs) = 22.4 cc.
If a label printer prints 9 pages in 1.7 seconds, to find the time to print 72 pages, we set up a proportion where 9 pages/1.7 seconds = 72 pages/X seconds. Solving for X gives us X = (72 pages x 1.7 seconds)/9 pages = 13.6 seconds.
1. Using subtraction, Yerald's current weight after losing 4 kg 750 g is 87 kg and 250 g.
2. Using division operation, the allowed grams of meat for each person, Jason is serving the 10 kg turkey, are approximately 357 grams.
3. Using mathematical operations, the total cost that Young-Mi paid to buy 2 kg 20 g of onion priced at $1.49 per kilogram is $3.01.
4. Based on the standard rate of an antibiotic, the standard dose for a 140-pound woman is 22.4 cc.
5. Using the printing rate per second, the time to print 72 pages of labels is 13.6 seconds.
What are mathematical operations?
The four basic mathematical operations include addition, subtraction, multiplication, and division.
These mathematical operations help us to determine the required values of algebraic expressions using mathematical operands and the equal symbol (=).
1. Yerald's Weight:
Past weight = 92 kg
The weight she lost = 4 kg and 750 g.
Current weight = 87.25 kg (92 - 4.75) = 87 kg and 250 g.
2. Jason:
The total weight of turkey = 10 kg
The total number of people being served = 28
1 kg = 1,000 grams
10 kg = 10,000 grams
The serving per person = 357.14 grams (10,000 ÷ 28)
= 357 grams
3. Young-Mi:
The weight of onions bought = 2 kg 20 g
1 kg = 1,000 grams
20 g = 0.02 kg (20 ÷ 1,000)
2 kg 20 g = 2.02 kg
The price per kilogram = $1.49
The total cost = $3.01 ($1.49 x 2.02)
4. Antibiotics:
Standard dose = 4 cc (cubic centimeters) for every 25 pounds of body weight
The standard dose for a 140-lb woman = 22.4 cc (4 x 140 ÷ 25)
5. Printing Rate:
The number of pages printed in 1.7 seconds = 9 pages
The total number of pages of labels = 72 pages
The time to print 72 pages = 13.6 seconds (72 ÷ 9 x 1.7)
