The diagram below shows the number of ice cream cones sold in a day at a local ice cream shop.

Based on these results what is the most reasonable prediction of the number of chocolate chip ice cream cones that will be sold out of the next 240 cones sold?

Answers

Answer:

Step-by-step explanation:

B-60

EXPLANATION:

If he sold 8 vanilla, 28 double scoop and 12 chocolate chip, it means he sold 12 chocolate chip out of 48. So he sold 12/48 chocolate chip, which equals 1/4. If we write it in percentages, we will see that 1/4•100%=25%. Now we need to know how many chocolate chips would be sold in next 240 cones. In conclusion, we need to calculate 25% of 240. So if 240 is 100% and X is 25%, then 240•25=100X. If we solve that equation, we will see that X=60, so 25% of 240 equals 60. In conclusion, the right answer is B.

A quadrilateral has 4 sides that are most of the time even

Part A: Use ratio language to describe the relationship of any two things you can think of.

Example: For every 5 minutes of jogging, I ran 500 yards.

Be creative and come up with your own idea.

Part B: Determine the unit rate in your example.

My example: For every 20 minutes i can read 7 pages

Answers

Ratio Language

First you need to know what this means... example "For every vote candidate A received, candidate B gets five votes." this would be shown as 1:5

The example here in the problem is 5 minutes for 500 yards as 5:500

__
For your example the 20 minutes and 7 pages, 20:7 pages your unit rate would be 2.85714286 minutes you read one page, or rounded to the tenths 2.86 minutes you read a page

Part A: Another example can be “ For every 10 minutes, Mia ate 2 pieces of cake.”

Part B: 20 minutes for 7 pages equals about 2 minutes for 1 page

The third one. I’ve shown my work below. The first two are positive and the last one is 0, which is neither positive nor negative

I know someone else responded but theres an easier way to solve this without multiplying anything.
Neg*neg=pos
1. Has two neg and two negs make a pos
2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg
4. Would just be 0 because its multiplying 0 but without it it would be neg.
So the answer is the third one

Answer: The ratio is 18:3

Step-by-step explanation:

Answer: 6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Answer and show your work (10 points)

Answers

Answer:

an average of 1.3 inches

Step-by-step explanation:

Using the mean absolute deviation, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.

What is the mean absolute deviation of a data-set?

The mean of a data-set is given by the sum of all observations divided by the number of observations.

The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.

The mean absolute deviation represents the average by which the values differ from the mean.

In this problem, the mean absolute deviation is of 1.3 inches, hence, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.

8x/13 = 64/52

If answer is in a decimal, put in fraction (simplest form)

Answers

x=2
Simplify 64/52
64/52=16/13
To get 16/13, you have to cancel out the common factor which is 4.
8/13x=16/13
8•13=104
13•16=208
208 / 104 = 2
Therefore,
x=2

Answer: 2

Step-by-step explanation: This is incredibly simple first we can match the denominators, 4*13 = 52 and that means we have to do that to numerators to, 8x*4 = 32x so now our equation is 32x/52 = 64/52 and as we know 32*2 = 64 so that means x = 2.

ACF=ECB because the are vertical angles (they are opposing each other). So if ECB is g° then ACF is also g°. Think of them as symmetrical.

53+g=90 because 90-53=g and 90-g=53. (I don't know how to explain it other than this)

g+53+90=180 because ACB is a straight line (straight lines are always 180 degrees) and g, 53, 90 all make up the straight line.

2%(x)+5%(3x)=1360

0.02(x)+0.05(3x)=1360

0.02x+0.15x=1360
