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

Find the volume of the composite solid below round your answer to the nearest tenth

Answers

First find the volume of the cylinder.

The formula is: V=πr²h

Plug the numbers in the figure into the formula.

V=πr²h

V=π×3²×10

V=π×9×10

V=π90

V=282.743

Therefore, the volume of the cylinder is approximately 282.7in³

Find the volume of the rectangluar prism.

V=lwh

V=12×7×4

V=84×4

V=336

Therefore, the volume of the rectangular prism is 336in³

Ariana earned $425 babysitting over the summer. She put 40% of what she earned into her savings account.

How much money did Ariana put into her savings account?

Answers

Answer:170

Step-by-step explanation:

$425 divided by 40% is 170

Solution:

What is 40% of 425?

Y is 40% of 425

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 40% * 425

Converting percent to decimal:

p = 40%/100 = 0.4

Y = 0.4 * 425

Y = 170

170

Explanation:
“Of” usually means multiplication:
425 x 40%
40% = 40/100 = 0.4
425 x 0.4

A Rover driving on the moon’s surface travels at a speed of 60 ft/min. How far will it travel in 90 min?

Answers

Answer:

d =5400 ft

Step-by-step explanation:

d = rt

where d is distance r is rate and t is time

d = 60 ft/ min * 90 min

d =5400 ft

Answer:

5400ft

Step-by-step explanation:

If you are travelling 60ft/min or 60 feet in one minute, you can multiply by 90 minutes to find the number of feet you will travel in that time.

60ft/min * 90min = 5400ft

If they want an approximate mileage, it is just above 1 mile. (1.022727miles)

1) Each lunch for a school field trip has a turkey, roast beef, or bologna sandwich, an orange or apple for a fruit, and a cookie or muffin for dessert. Amanda and Zack would like to…

-know the number of possible lunch options.

-P of having any meal with NO COOKIE.

(use sample space, tree diagram, and counting principle)

Answers

1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.

How to find the number of possible lunch options.

1) Number of possible lunch options:

To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.

- Sandwich: There are 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There are 2 options (cookie or muffin).

Using the counting principle, we multiply the number of options for each component together:

Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.

Therefore, there are 12 possible lunch options.

2) Let's examine the favorable outcomes for each component:

- Sandwich: There are still 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There is 1 option (muffin, as we want to exclude cookies).

Using the counting principle, we multiply the number of options for each component together:

Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.

The total number of possible outcomes is still 12 (as calculated in the previous step).

Therefore, the probability of having any meal with no cookie is:

P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.

Hence, the probability of having any meal with no cookie is 1/2 or 0.5.

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

Answers

Answer:

3.62 inches

Step-by-step explanation:

Given :

Ed's string length = 21.72 inches

Georgiana's string length = 1/6 of Ed's string length

To Find :

Georgiana's string length

Solving :

Georgiana's string length = 1/6 of Ed's string length

Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Georgiana's string length = 3.62 inches

Answer:

3.62 inches

Step-by-step explanation:

Step-by-step explanation:

Given that Ed's string length is = 21.72 inches

And that Georgiana's string length is = 1/6 of Ed's string length

We need to find Georgiana's string length

Georgiana's string length = 1/6 of Ed's string length

And Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Which would bring us that Georgiana's string length is = 3.62 inches
