Kori has 12 strawberries, 3 pineapples, and 4 kiwis. What is the ratio of strawberries to total fruit?
Anettt [7]

Answer:

12:19

Step-by-step explanation:

To create a ratio, we compare a portion to a whole. In this case our portion is 12 strawberries. Our whole is the total fruit, so let's add up each fruit to find the total.

12 + 3 + 4 = 19

Now we have our portion (12) and our total (19).

Let's create a ratio.

12:19

This ratio cannot be simplified further, so that is your answer.

Hope this helps!

How to the medium in the dot line????!! I don't want my mom to be mad at my grade please!!!!!!
SVETLANKA909090 [29]

Answer: To find the median, count the dots from left to right until you find the middle value.

Step-by-step explanation:

Ok so first it's not a dot line it's a dot plot. Second, let's define what a medium is. The medium is the "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. The middle number is 15, so the median is 15. Tip to find the median from a list of value ordered numbers every time cross a number from each side. For example, if you cross 13 from above also cross 26 and if you cross 23 then also cross 10.

Back to your original question of how to find the medium on a dot plot you need to take all the numbers from your dotted line put them in order even if they are repeated and then cross each one on each side from right to left. Also remember if you cross out all the numbers right and left and end up with two numbers left then take them and add them and then divide by 2 and that will be the median.

An example is attached on here in order to help you understand what I am saying. Hope this helps. Your welcome and I hope you make your mama proud.

At a hot dog stand, they serve regular and foot long hot dogs at a ratio of 3 to 2.Based on this ratio how many foot long hot do
Murrr4er [49]

Answer:

32 Foot long hot dogs

Step-by-step explanation:

A hot dog stand serves 3 regular hot dogs for every 2 foot long hot dogs. This means they sell 3+2 = 5 together.

If they sell 80 in one day, then you find how many of each by solving the equation 5x = 80.

5x = 80

x = 16.

So 3*16 is the number of regular which is 48.

So 2*16 is the number of foot long which is 32.
