Answer:

1.62 pounds

Step-by-step explanation:

Let x be the pounds of Arabica

Take the number of pounds times the cost of each of the coffees individually

This must be equal to the number of pounds times the cost together

x * 28 + 8.75 *3 = ( x+3) 15.50

28x+26.25=(x+3)15.50

Distribute

28x+ 26.25 = 15.50x + 46.50

Subtract 15.50x from each side

28x-15.50x +26.25 = 15.50x +46.50-15.50x

12.50x + 26.25 = 46.50

Subtract 26.25 from each side

12.50x +26.25-26.25 = 46.50-26.25

12.50x = 20.25

Divide each side by 12.5

12.5x/12.5 = 20.25/12.5

x =1.62

Answer:    \frac{1}{16}


Step-by-step explanation:

Given: The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders the day before the game was released.

The probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released

=\frac{35}{140}\times\frac{35}{140}=\frac{1}{4}\times\frac{1}{4}=\frac{1}{16}

Hence, The probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released is \frac{1}{16}.

Jose ran13 mile in 3 minutes and 15 seconds. Calculate Jose's rate in minutes per mile; in other words, the time that it would t
Alexus [3.1K]

Answer:

1 mile = 15 seconds

Step-by-step explanation:

3 minutes and 15 seconds = 3 min + 15 sec

1 minute = 60 seconds

15 seconds =15/60 = 0,25 min

then

3minutes and 15 seconds = 3.25 minutes

13miles in 3 minutes and 15 seconds

= 13 miles / 3.25 minutes

= 4 miles / 1 minute

every minute Jose ran 4 miles

then:

4 miles is a 1 minute

1 mile is a T minutes

T = 1*1/4

T = 1/4 minute

1 minute = 60 secomds

1/4 minute = 60*1/4 = 60/4 = 15 seconds
