(If you dont care much for the explanation)

ANSWER IS
$131.35


If 1 liter of milk is $17 3/4 we just need to find the cost for 7 2/5.
Since we’re working with money we have to turn the $17 3/4 and 7 2/5 into a decimal so its ($17.75) and 7.40

Anyways we multiply those numbers to find the cost of 7 2/5 liters
( 17.75 x 7.40) and the answer is $131.35

katen-ka-za [31]

Unit price would be the price per ounce.

Divide the total cost by the number of ounces:

Price Club : 2.59 / 12 = $0.216 per ounce

Shop Mart: 1-1/2 pounds = 1.5 x 16 = 24 ounces.

4.68 / 24 = $0.195 per ounce.

shepuryov [24]

Answer:  The required number of miles rode is 4.6875.

Step-by-step explanation: We are given to solve the following situation for the value of d :

Tori needed to take a taxi. The fare for  riding in a taxi is a $3 fixed charge and $0.80 per mile. The fare  for a ride of d miles is $6.75.

According to the given information, we have

3+0.80d=6.75\\\\\Rightarrow 0.80d=6.75-3\\\\\Rightarrow 0.80d=3.75\\\\\Rightarrow d=\dfrac{3.75}{0.80}\\\\\Rightarrow d=4.6875.

Thus, the required number of miles rode is 4.6875.

Mrs. Smith's class is working on a variety of science experiments. Each
SVETLANKA909090 [29]

Answer:

66

Step-by-step explanation:

If there are  <em>n</em>  students, then the number of pairs is \frac{n(n-1)}{2}.

With 12 students, \frac{12(12-1)}{2} = \frac{132}{2}=66 pairs can be formed.

The reason the formula works is this:  Each of the 12 students can be paired with 11 other students (no student is paired with him/her self).  But counting 12 x 11 = 132  counts each pair <u>twice</u>.  Example: student A can be paired with student B,..., student B can be paired with student A.  The pair was counted two times.

See the attached image that shows pairings of 5 students.  There are

5(5 - 1)/2 = 5(4)/2 = 10 pairs.
