We are asked to determine the lengths of the line segment drawn with these points as endpoints. The equation of the distance between points is,
                              d = sqrt ((y2 - y1)² + (x2 - x1)²)
Substituting the coordinates of the points,
                               d = sqrt ((14 - 9)² + (4 - 2)²)
The numerical value for d is approximately 5.39.

A race car driver lost 8 seconds off the leader for each of the 3 pit stops the driver made. At each of the next 2 pit stops the
julsineya [31]

Answer:

-4 seconds

Step-by-step explanation:

The question says he lost 8 seconds off the leader for each of the 3 pit stops that he made

8 x 3 = 24

This means that 24 seconds was lost.

If 10 seconds were gained for the next 2 pit stops, the driver gained a total of

2 x 10 = 20seconds

The amount of time he is off leader =

20 -24

= -4 seconds

We have it that -4 seconds represents time he is off the leader.

Thank you!

Sallie Woo worked these hours last week: Monday, 10; Tuesday, 8 1/4; Wednesday, 9 1/2; Thursday, 6; Friday, 8; Saturday, 5. Sall
almond37 [142]

Answer:

Her pay for the week= $ 611.325

Step-by-step explanation:

Sallie is paid $ 11.40 per hour for regular hours.

The total regular hours worked during the week are

Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours

She works overtime during the week

Monday + Tuesday + Wednesday = 2+ 1/4+  1 1/2=  2+ 1/4 + 3/2

= 8 +1+ 6/4=15/4 = 3 3/4 hours

Over the weekend she works five hours .

So the total pay would be

$ 11.40( 38 ) + $ 11.40( 1.5) (  15/4) + $ 11.40 ( 2) ( 5)

= 433.2 + 64.125 + 114.0

= $ 611.325
