A bag contained 18 red marbles, 14 green marbles, and 20 blue marbles. A marble was randomly pulled, the color recorded, and then put back into the bag. This table above shows the results after 25 pulls.

What was the relative frequency of selecting a red or blue marble?

Red:8
Blue8
Green9

Answers

Number of red marbles pulled = 8

Number of blue marbles pulled = 8

Total marbles pulled = 25

Relative Frequency = Total Frequency / Total number of data values

Relative Frequency of red marble = 8/25

= 32%

Relative Frequency of blue marble = 8/25

= 32%

Compare the dimensions of the prisms. How many times greater is the surface area of the green prism than the surface area of the blue prism?
the green prism has a height of 25 cm, a depth of 5 cm, and a length of 10 cm
the blue prism has a height of 10 cm, a depth of 2 cm, and a length of 3 cm
PLEASE HELP!!

Answers

Comparing the dimensions of the prisms, the number of times in which the surface area of the green prism is greater than the surface area of the blue prism is 7.59

Surface area of a prism

The formula for the surface area of a prism is SA=2B+ph, where B, again, stands for the area of the base, p represents the perimeter of the base, and h stands for the height of the prism.

Area of the base of prism = lw

Perimeter of the base of a prism = 2(l+w)

Surface area of the green prism

height of 25 cm, a depth of 5 cm, and a length of 10 cm

Area of the base of prism = lw = 10cm × 5cm = 50cm²

Perimeter of the base of a prism = 2(l+w) = 2(10+5) = 30cm².

SA=2B+ph

= 2 ( 50) + 30 × 25 = 100+750= 850cm²

Surface area of the blue prism

height of 10 cm, a depth of 2cm, and a length of 3cm

Area of the base of prism = lw = 3cm × 2cm = 6cm²

Perimeter of the base of a prism = 2(l+w) = 2(3+2) = 10cm².

SA=2B+ph = 2(6) + 10 × 10 = 112cm²

The number of times green prism is greater than blue prism = 850cm²/112cm² = 7.59

A thrift store was selling an Atari 2600 for $80 before deciding to have a 40% off promotion. A customer comes in to buy the console and pays with a 10% off any one item coupon. The coupon states that the 10% off coupon applies after any in-store promotions. The customer expects to get 50% off overall and pay 40.00. Is the customer correct?

Answers

Answer:

The customer is incorrect. They will pay $43.20 not $40.

Step-by-step explanation:

Since a thrift store is having 40% of $80, we have to calculate that. Doing so, we have to create proportions:

(The "/" sign is fraction)

1. x/80=40/100 2. 40*80=3200 3. x*100=100x 4. 100x=3200

5. x=3200/100 6. x=$32

Since $32 is 40% of $80, we have to do $80-$32=$48

So the thrift shop is lowering the price to $48.

But we can't forget about the 10% off coupon from the customer.

Now we have to find out what is 10% of $48. $48/10= $4.8

That's not our answer though. The final step is to do $48-$4.8 which gets our answer of $43.20 .

4) x = 32

5) x = 11

Step-by-step explanation:

Answer:

Step-by-step explanation:

11. -1= (5+x)/6 : to get rid of the 6 on the bottom multiply to both sides.

-6=5+x : subtract 5 to both sides

-11 = x

12. 2/3x + 2 = -4 : subtract the 2 to both sides

2/3x = -6 : divide 2/3 to both sides

x= -6/(2/3)

x=-9

13. 7x+2.5=-4.5 : subtract 2.5 to both sides

7x= -7 : divide by 7 to both sides

x= -1

14. 8-3/8x= -4 : subtract 8 to both sides

-3/8x = -12 : divide both sides by -3/8

x=32 : two negatives make a positive

15. -3x - 5 = -38 : add 5 to both sides

-3x=-33 : divide both sides by -3

x= 11 : two negatives make a positive

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the park are 12 inches wide by 20 inches long. A rectangular area of the park for swing sets is 0.5 inch wide by 2 inches long on the scale drawing.

What is the actual length of the swing set area of the park?

Enter your answer in the box.

The actual length of the swing set area of the park is ______ feet.

Answers

Answer: The dimensions of the park on the scale drawing is 12 inches and 20 inches.

Dimension

Actual dimensions:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

Swing set on the scale drawing= 0.5 inch by 2 inches

Hence:

Dimension of park on drawing:

Width = 600×1/50

Width = 12inches

Length = 1000×1/50

Length= 20inches

In conclusion the dimensions of the park on the scale drawing are 12 inches and 20 inches.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Answer:

Step-by-step explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

Then we have following equation to solve for x:

x + 60° + 80° = 180°x + 140° = 180°x = 180° - 140°x = 40°

X = 40 degrees
