Eli won 2 out of 3 chess games on day. At this rate, if he played 35 games, how many did he win? Write and solve a proportion

Answer:

The answer is C

Step-by-step explanation:

2 2/3 + 3 1/2

first, add the whole numbers

(2+3)+( 2/3+1/2)

=5 and then you multiply each fraction by the other denominators

2/3 x 2 and 1/2 x 3

=5 4/6 3/6

Now add each fraction because it is the same denominator

4+3=7 so it is 7/6 now to make it a mixed fraction

7/6=1 1/6

5 +1=6

6+1/6 = 6 1/6

Answer:

2.25

Step-by-step explanation:

15.00

-12.75

-----------

2.25

The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

As per the given,

15 - 12.75

⇒ (14 + 1) - (12 + 0.75)

Open bracket

14 + 1 - 12 - 0.75

14 - 12 + 1 - 0.75

2 + 0.25 = 2.25

Hence "The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25".

Answer:

A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)

The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:

4 lbs / $3  = 1lb / x       cross-multiply

4x = 3      divide by 4

x = 3/4 dollars = $.75 per pound

The point (8,6) means that 8 lbs. of potatoes = $6.

The simplified expression is [tex]27/(16x^6y^8).[/tex]

We have,

To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.

Let's simplify the numerator first:

[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]

Now, let's simplify the denominator:

[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]

Now we can divide the numerator by the denominator:

[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]

To divide the variables with the same base, we subtract their exponents:

[tex]27/16 * x^{6-12} * y^{12-20}[/tex]

Simplifying further:

[tex]27/16 * x^{-6} * y^{-8}[/tex]

To make the exponents positive, we can move the variables with negative exponents to the denominator:

[tex]27/(16x^6y^8)[/tex]

Therefore,

The simplified expression is [tex]27/(16x^6y^8).[/tex]

Answer:

The number line is divided by 6ths.

Step-by-step explanation:

There are 6 equally sized spaces between 0 and 1 on a number line. By definition of a fraction, a quantity is divided upon a number of equal parts in which can be expressed as the number of parts divided by the total number of parts. Therefore, the numerator in this case will be how many of the 6 parts are there at a certain point; the denominator will be 6, since there are 6 total, equal parts. In this case, think of the fraction as a distance traveled from 0 to 1 in 6 parts; the numerator is how far is traveled, and the denominator is the total travel distance. Point A is located at 1/6, since it is 1 out of the 6 pieces traveled. Point D would be at 5/6 because it has traveled 5 out of the 6 distances.

Point A is at  

✔ 1/6

Can you show more information please?

Answer:

Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :

y = 1.87x + 3.66

predicted amount of tip for 100 customers = $191

The predicted amount of tips received of 100 customers are served :

y = 1.87x + 3.66

x = 100 ; substitute x = 100 into the equation

y = 1.87(100) + 3.66

y = 187 + 3.66

y = 190.66

Hence, about $191 would be received on tips if 100 customers are recorded.

Using a regression calculator to make prediction from a data table :

Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

Step-by-step explanation:

Hi!

So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)

(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)

1(left)-7/1/4 is the same as 7/ .25. This is 28.

2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating

3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating

4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)

1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.

2(right) 1/4 x 7 is the same as .25*7. This is 1.75

3(right) 7*4 is 28.

4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533

Now, we can match.

Green is with C.

Blue is with A

Orange is with D

Purple is with B

Step-by-step explanation:

How do you evaluate fractions with whole numbers?

Multiply a fraction with a whole number by multiplying only the numerator. For example, 5 x 1/8 = 5/8. Multiply a fraction with another fraction by multiplying the numerators together and the denominators together. For example, 3/8 x 2/5 = 6/40 = 3/20.

Explanation:

You divide the two values given to get 63/7 = 9.

We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".

You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.
