Joel can run around a 14– mi track in 81 sec, and Jason can run around the track in 69 sec. If the runners start at the same poi
Alenkasestr [34]

Answer:37.2 sec

Step-by-step explanation:

Given

Joel takes 81 sec for 14 mile long track

speed of joel \frac{14}{1.35} mi/min=10.37 mi/min

Jason takes 69 sec for 14 mi track

so jason speed is \frac{14}{1.15} mi/min=12.17 mi/min

if both starts from same spot in opposite direction then

\frac{x}{10.37}=\frac{14-x}{12.17}

where x is distance covered by Joel

then x=6.44 miles

therefore time required

t=\frac{6.44}{10.37}=0.621 min\approx 37.2 sec

1. Which of the following is NOT true about an isosceles trapezoid?
viktelen [127]
On an isosceles trapezoid, the two sides that are not parallel to each other will be exactly the same length.  If this is true, than it would be create a symetric trapezoid.  The diagonals would be the same length.  The bases of any trapezoid are parallel, so this is true.  The diagonals cannot possibly be perpendicular because the 2 nonparallel sides would be slanted.  So, the answer is the 3rd choice.

Alex purchased 3 packs of baseball cards that cost $2.50 each. He also purchased 2 packs of card protectors that cost $3.00 each
vampirchik [111]

Answer:

6.50

Step-by-step explanation:

You have to add/multiply 2.50 by 3 to get the total cost of the cards. 2.50*3=7.5. then, you need to add/multiply 3.00 by 2 to get 6. 7.5+6= 13.5. 20-13.5=6.50.

the change was $6.50
