Given that the dealer sells a dozen tires for $240, every 3-tire set costs $60. There are six 2-tire sets in a dozen. Thus, his total revenue should be $360. The total profit is the difference between the total revenue and the total cost. The answer is therefore, the first choice, $120.

ExtremeBDS [4]

Answer:

26 hours

Step-by-step explanation:

speed = distance/time

s = d/t

st = d

t = d/s

t = (13 km)/(0.5 km/h)

t = 26 h

Answer: 26 hours

David sent a survey to 12 classmates. One week laterb9 of the surveys were returned what percent of the surveys were returned
Olegator [25]
9 of 12 were returned which is the same as 9/12. Reduce the fraction...

9/12 = 3/4

To find percent we need the denominator to equal 100 so if we multiply by 25/25...

3/4 × 25/25 = 75/100 =

75%

What are the endpoint coordinates for the mid segment of △PQR that is parallel to PQ?
diamong [38]

Answer:

So the end points of the mid segment are:

S(-3.5,0.5)

T(-1,-0.5)

Step-by-step explanation:

First of all we need to list the co-ordinates of the points of the triangle shown.

P\rightarrow(-3,3)

Q\rightarrow(2,1)

R\rightarrow(-4,-2)

We need to find mid segment of the triangle which is parallel to segment PQ. This would mean we need to find midpoints of segment PR and QR and then join the points to get mid segment.

Midpoint Formula:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Midpoint of PR:

S((\frac{-3+(-4)}{2},\frac{3+(-2)}{2})\\\\(\frac{-3-4}{2},\frac{3-2}{2})\\\\(\frac{-7}{2},\frac{1}{2} )

S(-3.5,0.5)

Midpoint of QR:

T(\frac{2+(-4)}{2},\frac{1+(-2)}{2})\\\\(\frac{2-4}{2},\frac{1-2}{2} )\\\\(\frac{-2}{2},\frac{-1}{2}

T(-1,-0.5)

So the end points of the mid segment are:

S(-3.5,0.5)

T(-1,-0.5)

By mid segment theorem we know that the line joining midpoints of two sides of a triangle is parallel to the 3rd side.

∴ We know ST is parallel to PQ
