1 answer:

5 0

2+5 = 7 is <span>the related addition sentence that shows the commutative property of addition because it has the same result of addition as 5+2=7.
Commu</span><span>tative property of addition says that if we have two numbers we have interchange them and this doesnot affect the result....</span>

Delia is a graphic designer who charges an hourly rate. She made the graph to show her total earnings for various numbers of hou

stich3 [128]

Answer:

approximately 7 hours

see the explanation

Step-by-step explanation:

The picture of the question in the attached figure

Let

x ----> the time worked in hours

y ----> the amount earning in dollars

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem we have a proportional relationship

step 1

Find approximately how many hours would it take Delia to earn $250 ?

Looking at the graph

For y=$250 The value of x is approximately 7 hours

see the attached figure N 2

step 2

Find the exact value

from the graph take the point (5,175)

Find the value of k

$k=\frac{y}{x}$ ----> $k=\frac{175}{5}=\$35\ per\ hour$

The linear equation is

$y=35x$

For y=$250

substitute

$250=35x$

solve for x

$x=7.14\ hours$

Make 80/6 to a mixed number explain how u got your answer

Deffense [45]

Answer:

13 $\frac{1}{3}$

Step-by-step explanation:

The closest multiple of 6 less than 80 is 13.

13×6=78

How many are left over?

80 - 78 = 2

$\frac{2}{6}$ remains, and this can be simplified to $\frac{1}{3}$

13 $\frac{1}{3}$

Hope this helps!! (I know it sounds a little complicated but it's easy to understand it with practice :)

The table and scatter plot below show the number of hits and runs Tyler's baseball team got in each of 12 tournament games.

agasfer [191]

The correct statements are:

There is a positive linear equation between the number of hits and the scores
The point (7,13) is an outlier.
If the trend continues, for a game when Tyler's team gets 20 hits, the number of runs scored would be greater than 10 hits.

<h3>What are the correct statements?</h3>

An outlier is a number that is way smaller or way larger than that of other numbers in a data set. On a trend line, an outlier would be far from the trendline.

A positive linear relationship is when as one of the variables increase, the other variable also increases and the trendline is a straight line that is upward sloping.

Find the 25th term of the arithmetic sequence whose common difference is d=5 and whose first term is a1 = 3 .

Maru [420]

$\bf n^{th}\textit{ term of an arithmetic sequence} \\\\ a_n=a_1+(n-1)d\qquad \begin{cases} a_n=n^{th}\ term\\ n=\textit{term position}\\ a_1=\textit{first term}\\ d=\textit{common difference}\\[-0.5em] \hrulefill\\ a_1 = 3\\ d= 5\\ n = 25 \end{cases} \implies a_{25} = 3+(25-1)5 \\\\\\ a_{25} = 3+(24)5\implies a_{25} = 3+120\implies a_{25} = 123$
