Answers

Answer 1
Answer:

Answer:

Maximum number of oranges Lois can send is:

50

Step-by-step explanation:

Lois wants to send a box of oranges to a friend by mail.

The box of oranges cannot exceed a mass of 10 kg.

1 kg=1000 g

10 kg=10000 g

i.e. Mass of box cannot exceed 10000 g

Each orange has a mass of 200 g.

Mass of 50 oranges=50×200 g

                                =10000 g

Hence, maximum number of oranges Lois can send is:

50
Answer 2
Answer: easy first cover kilograms into grams 1kg=1000g. resulting in 10,000g dividing that by the weight of the oranges getting 10,000/200=50 so the answer is 50 oranges. (assuming they all weigh the same)

Multiply 6/5 x 25/24

Answers

Hi there! 6*25=150 and 5*24=120. Now, we have a fraction of 150/120. The GCF of 150 and 120 is 30 so we are going to divide 150/120 by 30. 150÷30=5 and 120÷30=4. So, we have a fraction of 5/4. 5/4 as a mixed number is 1 1/4. Therefore, the answer is 1 1/4.

The number of chips of different colors in Amy's bag is shown below: 8 blue chips 9 pink chips 1 white chip Amy takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Amy takes out a pink chip in both draws.

Answers

Answer:

1/4

Step-by-step explanation:

8 blue chips 9 pink chips 1 white chip = 18 chips

P( pink) = pink/total = 9/18 = 1/2

Replace

8 blue chips 9 pink chips 1 white chip = 18 chips

P( pink) = pink/total = 9/18 = 1/2

P(pink, replace, pink) = 1/2 * 1/2 = 1/4

Steps:

blue chips = 8

pink chips = 9

white chips=1

total          = 18

Description:

As we know that the blue chips was 8, pink chips was 9, and white chips was 1. We plus all the numbers and your answer will equal as 18. Since the pink chips are 9 and the total is 18, we put then as a fraction. So 9/18=1/2. But the answer will be 1/4

Answer: 1/4

1st draw:

pink chip = 9/18 = 1/2

2nd draw:

pink chip = 9/18 = 1/2
