A bag of chocolates is labeled to contain 0.384 lbs. The actual weight of the chocolates is 0.3798 lbs.

Answers

Answer:

The answer to your question is the chocolates are slightly lighter than the weight stated on the label.

Step-by-step explanation:

Data

The label says 0.384 pounds

Actual mass = 0.3798 pounds

Process

To solve this problem the only thing we must do is substrate the actual weight of chocolates to the weight of chocolates stated on the label.

If the result is positive, then the chocolates are lighter

If the result is negative, then the chocolates are heavier

          0.384 pounds - 0.3798 pounds = 0.0042

ok? what’s the question? the difference is 0.0042

Jimmy takes 12 minutes to run 6 times around a 600 meter track. Assuming he runs at a constant speed, how long does he take to run 1 kilometer?

Answers

Answer:

10/3 minutes

Step-by-step explanation:

12 minutes to run 6 times is the same as 2 minutes to run once (ratios)

so it takes 2 minutes to run once around a 600 m track

so 2 minutes/600m = x minutes/1000m

x = 2/600 * 1000 = 20/6 = 10/3

Answer:

10/3

Bella has $26.00 to spend at a craft store. She buys fabric that costs $18.62. She also wants to buy knitting needles for $7.32, silk flowers for $7.38 or oil paints for $8.48. Use the equation $18.62 + c = $26.00, where c is the item cost, to find the most expensive item Bella can buy. Show your work and explain how you found your answer. Be sure to write your answer in a complete sentence.

Answers

The answer is 3 dollars and 07 cents
Answer: Silk Flowers ($7.38)

Explanation:
STEP ONE:
Subtract 18.62 from 26
26-18.62=7.38
STEP TWO:
Match up the answer to the costs
7.38 > Needles (7.32)
7.38 < Paints (8.48)
7.38 = Flowers (7.38)
Evidently, the flowers are the most expensive thing Bella can buy.
STEP THREE:
Check your answer
18.62 + 7.38 = 26
Equation checks out
FINAL ANSWER:
Silk Flowers

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?

Answers

Answer:

$460.20

Step-by-step explanation:

499*15% = 74.85 (total discount price)

499-74.85 = 424.15 (deduct discount from original price)

424.15*8.5% = 36.05275 (total tax from price)

424.15+36.05275 = 460.20275 (add tax to discounted price)

the answer is $460.20

Solve the following system of equations.

2x+y=3

x=2y+1

Make sure there are NO SPACES in your answer. Include a comma in your answer.


ANSWER: {( )}

Answers

2x+y-3=0,x-2y=1 okay that's the answer good luck
subtract y from both sides
now we have
2x = -y + 3
divide both sides by 3
x= -y/2 + 3/2
the other x equals 2y +1, set these equal to eachother

2y + 1 = -y/2 + 3/2

add y/2 to both sides

2.5y + 1 = 3/2

subtract 1 from both sides

2.5y = 0.5

divide both sides by 2.5

y=0.2

plug in 0.2 for y in an original equation

x = 2(0.2) + 1

solve

x = 1.4

ANSWER:
x= 1.4
y= 0.2
