The Sharks have played 5 basketball games this season. Their scores are 65, 63, 67, 60, and 65. If they only score 30 points in their next game, what will happen to their MEDIAN score?

Answers

the median of the scores now is:

60 , 63 , 65 , 65 ,67

Median = 65

if the score 30, the median would be

30, 60 , 63 , 65 , 65 ,67

Median: 63 +65 = 128/2 = 64

The Median drops by 1

In their first five games their median would be 67 because it is the middle number. But if they score 30 points then you would have to add 67+60 and get 127. Then you divide 127 by 2 and get 63.5. The median would be changed to 63.5.

Carmen, Reuben, and Bob have a total of $133 in their wallets. Bob has 3 times what Reuben has. Carmen has $8 more than Reuben. How much does each have?

Answers

So you will want to form a few equations. The first one is:
C+R+B=133
Then you will want to form an equation for Bob:
B=3R
Then, another for Carmen
C=R+8

Knowing this information, you can plug each in, solving for R.

R+8+R+3R=133      Now Solve
5R+8=133               Subtract 8 from both sides
5R=125                   Divide 5 from both sides
R=25                       Now substitute R in for Carmen and Bob equations.

R=25                        Reuben has $25
C=8+25                    Add
C=33                        Carmen has $33
B=3(25)                    Multiply
B=75                        Bob has $75

Check answer:

25+33+75=133
133=133

What is the median and mode

Answers

Median is the middle number

60, 60, 65, 70, 70, 85, 90

70 is your median

mode is the number(s) that show up the most
60 and 70 is your mode, since they show up twice (one more than the others)

Range is largest number minus the smallest
90 - 60 = 30, 30 is your range

Mean is all the numbers added together divided by the number of numbers there are 
60 + 90 + 65 + 70 + 70 + 85 + 60 = 500
500/7 = 71.42
Mean = 71.42

Answers

Facts: scale .25"=2'
room 60'×100'

Equation: 60/2=30×.25=7.5
100/2=50×.25=10.5

Answer: B

The new dimension in inches is 7.5 inches by 12.45 inches. Hence, option B is correct.

What is ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.

As per the given information in the question,

One fourth inch equal to 2ft.

Mathematically,

1/4 inch = 2ft

0.25 inch = 2ft

The given dimensions are 60 ft by 100 ft.

Now,

0.25 inch = 2ft

x inch = 60 ft

2x = (0.25 × 60)

x = 15/2

x = 7.5 inches

Then,

0.25 inch = 2ft

y inch = 100 ft

2y = 100 × 0.25

y = 25/2

y = 12.45 inches

Answers

6 feet because 8 / 12 reduces to 2 / 3 and you multiply 2 times 3
Hi there.

So, we've got the dimensions. 

l = 12, w = 8

We know that the width has been divided by 4. That means we also divide the length by 4. This gives us the new dimensions of:

l = 3, w = 2

A = lw

The sun produces 3.8x10^27 joules of energy per second. How much energy is produced in a year? (Note: a year is approximately 31,000,000 seconds.) Put it in scientific form.

Answers

If you're talking about the 'scientific notation', the answer would be (3.800000000000000000000000000, 26 zeroes.) 

Answer: About [tex]\approx1.178\times10^{35}[/tex]

Step-by-step explanation:

Given : The sun produces[tex]3.8\times10^27[/tex] joules of energy per second.

It is also given that a year is approximately 31,000,000 seconds.

In scientific notation , it can be written as [tex]3.1\times10^7[/tex]

Then , the amount of energy is produced in a year will be :-

[tex]3.8\times10^{27}\times3.1\times\times10^7\\\\=3.8\times3.1\times10^{27}\times10^7\\\\=11.78\times10^{27+7}\\\\=11.78\times10^{34}=1.178\times10^{35}[/tex]

Hence,  the amount of energy is produced in a year  [tex]\approx1.178\times10^{35}[/tex]

The movie theater has 176 seats there are 9 roles of 18 sets plus and additional section of handcapped accessible seats

Answers

Final answer:

The question is asking about the number of seats in a movie theater with 9 rows of 18 seats each and an additional section of handicapped accessible seats. The total number of seats can be found by multiplying the number of seats in each row (18) by the number of rows (9) and adding the number of handicapped accessible seats.

Explanation:

The subject of this question is Mathematics. The question is asking about the number of seats in a movie theater, given that there are 9 rows of 18 seats each and an additional section of handicapped accessible seats.

To find the total number of seats in the theater, you can multiply the number of seats in each row (18) by the number of rows (9) and then add the number of handicapped accessible seats.

So the total number of seats in the theater is 9 rows x 18 seats/row + additional handicapped accessible seats.

Find the length of each side

Answers

This can only be answered if we know that segments BG, CF, and DE are parallel. I don't see that written anywhere. I'll assume that is given.

To find GF:

AG is to AB as GF is to BC

AG/AB = GF/BC

20/16 = GF/12

5/4 = GF/12

4GF = 5 * 12

4GF = 60

GF = 15

To find FE:

AG is to AB as FE is to CD

AG/AB = FE/CD

20/16 = FE/8

5/4 = FE/8

4FE = 5 * 8

4FE = 40

FE = 10

25% of all the seats in the auditorium is 37 shares the total number of seats in the auditorium is

Answers

The number of seats in the first row is 18;
The number of seats in the second row is 18+2=20;
The number of seats in the third row is 18+2*2=22;
The number of seats in the fourth row is 18+3*2=24;
...
The number of seats in the nth row is 18+(n-1)*2.

Notice that if we knew the total number of rows we would be able to sum the number of seats in each row and get the total number of seats.

(1) The number of rows of seats in the auditorium is 27. Sufficient.
(2) The number of seats in the last row is 70 --> 18+(n-1)*2=70, where n is the number of rows. We can get n. Sufficient.

How do I combine like terms? For example one problem is 32y + 5y = please explain.

Answers

Step 1: Combine the coefficients. 32y + 5y are coefficients. (means have the same letter basically)
SO 32y + 5y= 37y
You can't combine oranges with apples, just oranges with oranges and apples with apples. Think about it that way.

In this specific problem, the only thing you need to do is add those numbers together as they are like terms (both have y), you'd get 37y.

With a problem like 2 + 5x + 3 + x, you'd have to identify which are like terms and which aren't. The x's go together, and 2 and 3 go together. The result would be 5 + 6x, since you can't combine x and 5.
