Answer:2182 after expenses

Step-by-step explanation:0.30×800= 240 miles

60×50=3000 dollars

3000minus the miles 240 minus the supplies 380 minus the other expenses 198

PLZ HELP MEEEE 40 POINTS!

ASHA 777 [7]

Step-by-step explanation:

We have been given that Jeanie stated that the equation of this line best fit for the scatter plot is $y=\frac{1}{2}x+8$ .

Let us find the slope of the line of best fit using points (2,7) and (4,6) in slope formula.

$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\text{Slope of line of best fit}=\frac{6-7}{4-2}$

$\text{Slope of line of best fit}=\frac{-1}{2}$

We can see that slope of line of best fit is $-\frac{1}{2}$ .

Since the equation of a line written in slope-intercept is in form: $y=mx+b$ , where m=slope of line, b= y-intercept.

Upon substituting m= $-\frac{1}{2}$ and coordinates of one point in slope-intercept form of equation we will get,

$6=-\frac{1}{2}\times 4+b$

$6=-2+b$

$6+2=-2+2+b$

$8=b$

Upon substituting m= $-\frac{1}{2}$ and b=8 in slope intercept form, we will get,

$y=-\frac{1}{2}x+8$

We can see that equation of the line of best fit is $y=-\frac{1}{2}x+8$ . Jeanie got 1/2 as slope of the line of best fit, which is wrong, therefore, Jeanie's equation of the line of best fit is not correct.

Given a two-digit number, make a three digit number by putting a 6 as the rightmost digit. Then, add 6 to the resulting three di

VladimirAG [237]

By working backwards,
you get 76 as your answer because you have to remove the rightmost digit, right? so the three-digit number is 

76x 
(x stands for the rightmost digit, because we don't know what the rightmost digit is) 

we are told we have to add six to the three digit number to get 76x, so we have to subtract 6 from 76x: 
76x - 6 = ??? 

since we assume that the original two-digit number is NOT 76, and any number from 760 to 765 inclusive minus 6 is logically in the 750-range, we can conclude that the original two-digit number is 75.

PLEASE HELP!! ASAP NOWWWW Two races that a student runs every year are the 1492-mile race in his hometown and the -meter race

Softa [21]

Answer:

College town race is 31% of the home town race.

Step-by-step explanation:

Length of hometown race = 3 miles

Length of college town race = 1492 meters

Since 1 meter = 0.0006214 miles

Therefore, 1492 = 0.93 miles

Percentage of college town race to the hometown race,

= $\frac{\text{College town race}}{\text{Home town race}}\times 100$

= $\frac{0.93}{3}\times 100$

= 31%

Therefore, the college town race is 31% of the home town race.

lucas lives 5/8 mile from school.kenny lives twice as far as lucas from school.how many miles does kenny live from school

dexar [7]

1. Lucas Lives 5/8 miles from their schools
=> 5/8 miles is equals to:
=> 5 / 8 = 0.625 miles.
Now, the problem says that Kenny lives twice as far as Lucas from their school.
Therefore, we only need to multiply the total number of miles of Lucas distance from house to school to be able to get what is the distance of Kenny’s house to school
=> 0.625 * 2 = 1.25 miles or 1 and ¼ miles.
