A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?

1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x

Answers

Answer:

1. y = 12.50x + 30

Step-by-step explanation:

A holiday meal cost $12.50 a person plus a delivery fee of 30$

Let x = number of people ordering a meal and y = total cost

It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.

There is also a $30 delivery fee.

So the total cost would (y) = 12.50x + 30

The answer would be 1. 12.50 and 30 just swapped places.

y=12.50x= 30

Solve for b.

b - 7 = -20
A. b = -27
B. b = -13
C. b = 13
D. b = 27

Answers

Answer:

B. b = -13

Step-by-step explanation:

b - 7 = -20

move variables and numbers to different sides of the equal sign by adding 7 to both sides

b - 7 + 7 = -20 + 7

b = -13

your answer would be -13 :) have a good day

Question: 5/12 − 2/5= 1/60​


A. The answer 1/60 is not reasonable because ​5/12​ is closer to 1 than to ​1/2​, and ​2/5​ is closer to 0 than to ​1/2​, making the difference close to 1/2. ​

B. The answer​ 1/60 ​is not reasonable because ​5/12​ is closer to ​1/2​ than to 1, and ​2/5​ is closer to 0 than to ​1/2, making the difference close to​ ​1/2​. ​

C. The answer 1/60 is reasonable because both fractions are closer to 1/2 than they are to 0, making the difference close to 0.

D. The answer 1/60 is reasonable because both fractions are closer to 1 than they are to 1/2, making the difference close to 0.

Answers

Answer:

C

Step-by-step explanation:

It is reasonable: the answer is both reasonable and correct because 5/12 - 2/5 = 1/60. This is because using cross multiply, 5 x 5/12 = 25/60, 12 x 2/5 = 24/60. 25/60 - 24/60 = 1/60.

Both are closer to half: half out of 12 would be 6/12 and 0 would be 0/12, so 5/12 is closer to half because 5/12 is closer to 6/12 than 0/12. Half out of 5 would be 2.5/5 and 0 would be 0/5, so 2/5 is closer to half because 2/5 is closer to 2.5/5 than 0/5.

The difference is close to 0: 1/60 is very close to 0. It's only worth 0.016.

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.

what is the fraction for the right handed people

Answers

Answer:

Step-by-step explanation:

12% is equivalent to 12/100.  This reduces to 3/25.  Thus, 3/25ths of the students are left-handed.  The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths.  There are more right-handed people (22/25ths) versus left-handed people.

Yes the answer above is right. 12% of the class is left but in fraction form it is 12/100 because a whole percent is 100% so 12 out of 100 is 12% :) hope it helped

Answer:

  4188.79 yd^3

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr^3

A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...

  V = 4/3π(10 yd)^3 = 4000π/3 yd^3 ≈ 4188.79 yd^3

Rounded to tenths, that's approximately 4188.8 yd^3.

Answer: See the diagram below

==========================================================

Explanation:

She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.

---------------------

For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)

|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11

This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.

---------------------

The last thing to do is find the mean of the set {10,4,1,4,11}

add: 10+4+1+4+11 = 30

divide by five: 30/5 = 6

The mean absolute deviation (MAD) is 6

This represents the average distance each data value is from the mean.  The MAD tells us how spread out the data is. It's similar to the standard deviation.
