Ashley has a total of $35 to spend at the carnival this year. She wants to purchase a turkey leg for $12, also. If each ride costs $0.50, how many rides can Ashley get on? IDENTIFY THE CONSTANT.

Answers

Answer:

46 rides; the constant is the $12 turkey leg

Step-by-step explanation:

To solve this, you can write an equation:

c = .5r + 12

where c is cost and r is rides (the constant is 12 because it doesn't change)

You already know that the cost is 35, so you just need to plug it in and solve:

c = .5r + 12; c = 35

35 = .5r + 12

23 = .5r

r = 46

So, on $35 and an expense of $12, Ashley can ride 46 rides.

Answer:

Ashley can go on 46 rides

Step-by-step explanation:

12+0.50x=35

-12               -12

0.50x=23

0.50x/0.50= 23/0.50

 x=46

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.

18/3

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.

solve the proportion x=____

Answers

Answer:

x = 77

Step-by-step explanation:

We can use cross products to solve the proportion.

x            44

----- =  ------

35         20

20 * x = 35 * 44

Divide each side by 20

20x / 20 = 35*44/20

x = 77

Answer:x=77 I hope this helps you and others

Step-by-step explanation:

x/35=44/20

Cancel out the common factor 4 the numbers are 44/20

X/35=11/5

Simplify the equation using cross-multiplication something like this

5x=385

Divide both sides of the equation by 5

Then you will get your answer

X=77

Step-by-step explanation:

sorry I couldent find that answer for question 3 or 4.

I'll do #1 & #2, but you have to do the rest on your own, I'm sorry.

#1 Answer:

The median height of giraffes is:

18 feet.

Step-by-step explanation:

We are given height, in feet, of 9 giraffes as:

           18, 16, 22, 14, 17, 19, 15 ,19,22

Now to find the median height of giraffes in the zoo we need to arrange the given data set in ascending order as:

14     15     16   17    18     19    19    22    22

Now we know that median is the central tendency of the data i..e it lie in the middle of the data set.

The value that lie in the middle of the given data set is:

18.

Hence, the median height of giraffes is:

18 feet.

#2 Answer:

The median of the sizes of the four parks is:

                        Option: C    33 acres.

Step-by-step explanation:

We are given area of four parks as:

27 acres    30 acres      34 acres      49 acres.

We know that the median of a data is the central tendency of a data and always lie in between or middle of the data set.

Hence, here the median will lie between 30 and 34

and hence is calculated as:

\(Median = \frac{30+34}{2}\)

\(Median = \frac{64}{2}\)

\(Median = 32\)

which is close to 33.

Hence, the median size of the park is:

                             33 acres.

what is the average between (25,28.8,39.2,51.2,64.8,80)? Please help me!

Answers

Answer:

48.17

Step-by-step explanation:

Average = sum of numbers / number of numbers

Sum of numbers = 25 + 28.8 + 39.2 + 51.2 + 64.8 + 80 = 289

Number of numbers = 6

Average = 289 / 6 = 48.17

Average/Mean = 25+28.8+39.2+51.2+64.8+80 /6

=>average = 289/6 = 48.167

( since average = sum of observations divided by number observations)

The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below:


Step 1: 4(2x − 4) = 8 + 2x + 8

Step 2: 6x − 8 = 16 + 2x

Step 3: 6x − 2x = 16 + 8

Step 4: 4x = 24

Step 5: x = 6



In which step did the student first make an error and what is the correct step?


Step 2; 8x − 4 = 2(6 + x + 6)

Step 2; 8x − 16 = 16 + 2x

Step 3; 6x − 2x = 16 − 8

Step 3; 6x + 2x = 16 + 8

Angle X; 39Angle Y; 129

Step-by-step explanation:

90

This gives us the measurement of 51+x.

90-51

39

This is x as well as the angle that is across from it.

x+90=y

39+90=129

y=129.

to find the last angle, we add 90 to 51. This gives us 141.

So, now we add up all of the angles to double check everything. If they all add up to 360 then we are correct.

39+39+51+90+141=
