The library has 65400 art books and 9600 science books. What part of all the books are science books

Answers

Answer:

9,600/75,000, 16/125

Step-by-step explanation:

art+science=75000

9600

75000    =16/125

The part of all the books that are science books is 0.128 or 16/125.

Using this formula

Science books=Science books(Art books+Science books)

Where:

Science books=9600

Art books=65400

Let plug in the formula

Science books=9600/(65400+9600)

Science books=9600/75000

Science books=0.128 or 16/125

Inconclusion the part of all the books that are science books is 0.128 or 16/125.

Hari's weekly allowance varies depending on the number of chores he does. He received $22 in allowance the week he did 16 chores, and $16 in allowance the week he did 4 chores. Write an equation for his allowance in slope-intercept form.

Answers

9514 1404 393

Answer:

  y = 0.5x +14

Step-by-step explanation:

If we let x and y represent the number of chores and Hari's allowance, respectively, then we have the two points (16, 22) and (4, 16). We can use the 2-point form of the equation for a line to find the equation.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (16 -22)/(4 -16)(x -16) +22 . . . . substitute

  y = -6/-12(x -16) +22 . . . . simplify

  y = 1/2x -8 +22 . . . . eliminate parentheses

  y = 0.50x +14

Answers

Given:

The function is

[tex]y=3x[/tex]

Domain of the function is {9, 15, 18, 21, 27}.

To find:

The range of the function.

Solution:

We have,

[tex]y=3x[/tex]

Domain is set of input (x-values) and range is the set of output (y-values).

Domain =  {9, 15, 18, 21, 27}

For x=9,

[tex]y=3(9)=27[/tex]

For x=15,

[tex]y=3(15)=45[/tex]

For x=18,

[tex]y=3(18)=54[/tex]

For x=21,

[tex]y=3(21)=63[/tex]

For x=27,

[tex]y=3(27)=81[/tex]

So, the y-values are 27, 45, 54, 63, 81.

Therefore, the range of the function is {27, 45, 54, 63, 81}.

Note: Options are not in proper form.

I have a very relaxing break playing Solitaire as often as I could. After playing 500 games, my success rate is 49%. How many games do I need to win to increase my success rate to 50%?

Answers

Answer:

5 more games to be won for the 50% success rate.

Step-by-step explanation:

Total number games played = 500

Number of successful games = 49% of 500

                                                 = 500 × [tex]\frac{49}{100}[/tex]

                                                 = 245

Number of successful games for the success of 50% = 500 × [tex]\frac{50}{100}[/tex]

                                                                                        = 250

Therefore, number of game you have to win more = 250 - 245

                                                                                    = 5 games

A baker made 9 cupcakes, each a different type. Four people want to share them equally. How many cupcakes will each person get? DIvide and use in fraction form.

Answers

Answer: 2 1/4

Step-by-step explanation:

From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.

To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:

= 9 ÷ 4

= 2 1/4 cupcakes

Therefore, each person gets 2 1/4 cupcakes.

M<2=x+88 can you please tell me the answer for this

Answers

Answer:

Answer: A) -8

Step-by-step explanation:

The image shows the triangle where it can be noted that two of its sides are congruent (according to the tick marks). This forms an isosceles triangle that also has two congruent angles as shown in the image below.

The other angle (2) has a measure of x+88.

The sum of the internal angles of the triangle must be 180°, thus:

x + 88 + 50 + 50 = 180

Simplifying:

x + 188 = 180

x = 180 - 188 = -8

x = -8

Answer: A) -8

i need help if yall can help me​

Answers

Answer:

C. 5.8

Step-by-step explanation:

We use the Pythagoras theorem here. which is a²+b²=c².

a and b are the replacements for the 5miles and  3miles here.

They are a and b because a  and b are always on the right angle side.

The longest side of this triangle is called a hypotenuse which is the c in this case.

the other sides (a and b) are called the adjacent and the opposite.

it doesn't matter if you use adjacent or opposite for a and b in this case.

the only important thing is the hypotenuse here.

So it's a²+b²=c², which is 5²+3²=c².

5² is 25 and 3² is 9, so we add them and we get 34.

so c²=34, we don't want the square on c  so we send it to 34 which becomes √34.

√34 gives us 5.8 miles which is up to just only one decimal place.

You might need to use calculators for square roots because they take long to calculate.
