Answer:

66.67%

Step-by-step explanation:

The distance Emma has run is 19.65 miles.

The distance Kelton has run is13.1 miles.

We want to express 13.1 miles as a percentage of 19.65 miles.

The quantity that comes after 'of' becones the base or denominator.

\frac{13.1}{19.65}  \times 100\%

0.6667\times 100\%

Multiply by 100 by moving the decimals forward twice.

66.67\%

Therefore Kelton has covered 66.67% of Emma's distance.

Edgar Anderson earns $300 per week plus 15% commission on all sales over 1,000. if Mr. Anderson's sales for one week are 2,500 w
vredina [299]
Since he only makes commission on sales over $1000, he makes commission on $1500 (we find this by doing 2500-1000.) His commission is 15%, so find 15% of $1500:
.15*1500=225
So we know how makes $225 in commission.

Now we need to add this to his fixed pay to get his total pay:
225+300=525
So his total pay is $525, which is answer 'a' 

Hope I helped, and let me know if you have any questions :)

Given the following equation in point-slope form. Identify the slope and the point.
nordsb [41]

Answer:

point = (-3, 5)

slope = 3/4

Step-by-step explanation:

The formula for point slope is:

y - y1 = m (x - x1)

point (x1, y1)

slope m

So with your equation:

y - 5 = 3/4 (x+ 3)

point = (-3, 5)

slope = 3/4

NO LINKS!! Explain your answers (show the support by showing the changes in x and y on your table). If the relationship is linea
sdas [7]

Answer:

<u>Linear relationship</u>: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.

<u>Inverse relationship</u>:  the value of one variable decreases as the value of the other variable increases.

<u>Exponential relationship</u>: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)

<u>Question 5</u>

As the x-value increases (by one unit), the y-value decreases.

Therefore, this is an inverse relationship.

The y-values are calculated by dividing 35 by the x-value.

\sf y=\dfrac{35}{x}

**I believe there is a typing error in the table and that the y-value of x = 3 should be 11.67**

<u>Question 6</u>

As the x-value increases, the y-value increases.  The y-value increases by a factor of 5 for each x-value increase of 1 unit.

Therefore, this is an exponential relationship.

\sf y=5^x
