The number of teams she can make is 10.

<h3>How many teams can she make?</h3>

Division is the process of putting a number into equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. Other basic mathematical operations include addition, subtraction, multiplication.

The number of teams that can be made can be determined by dividing the total number of friends by the total number of players in each team. The whole number that is derived from the division process is the number of teams teams that can be made given the total number of friends and the number of people that have to be in each group.

Number of teams she can make = total number of friends / number of people in each group

31 / 3 = 10 remainder 1

So, only 10 teams can be made. one person would not be on any team.

There were 254 tickets purchased for a major league baseball game. The lower box tickets cost ​$12.50 and the upper box tickets
Jet001 [13]
This can be solved by creating a system of equations.
x + y = 254
12.5x + 10y = 2745
We can then use substitution to solve the system.
x = 254 - y
12.5(254-y) + 10y = 2745
3175 - 12.5y + 10y = 2745
-2.5y = -430
y = 172
Finally, we can use that answer to solve for x.
x + 172 = 254
x = 82

So, there were 82 of the lower box tickets sold and 172 of the upper box tickets sold.

Please help me with these problems
CaHeK987 [17]

Answer:

3. 9

4. 5 pounds

5. 5/12 of a pound

Step-by-step explanation:

3. "at least 3/8" means to include that column in the count.

4. 3(1/4) + 4(3/8 ) + 3(1/2) + 2(5/8)

= 3/4 + 12/8 + 3/2 + 10/8 but we need a common denominator. LMK in the comments if you need help with that

= 6/8 + 12/8 + 12/8 + 10/8

= 40/8

= 5 pounds.

5. For the average, we add up all the weights, then divide by the number of kittens. Thankfully, we just added everything up in #4. Since we're going to be dividing 5 by 12, we'll end up with a decimal. But since the whole problem was written in fractions, we'll keep it in fractions.

40/8 divided by 12 kittens

40/8 divided by 12 = 40/8 muliplied by the inverse of 12 which is 1/12

40/8 x 1/12

= 40/96

Our numerator and denominator can be evenly dived by 8, so the fraction is reduced to

= 5/12

I'm happy to answer any questions.

otez555 [7]

Answer:

1.8

Step-by-step explanation:

The graph of the problem is plotted using Asymptote and attached.

From the graph:

  • 6 Families had 0 Pets
  • 3 Families had 1 Pets
  • 3 Families had 2 Pets
  • 6 Families had 3 Pets
  • 1 Family had 4 Pets
  • 1 Family had 5 Pets

There are a total of 20 families.

Average Number of Pets

=\dfrac{6*0+3*1+3*2+6*3+1*4+1*5}{20} \\\\=\dfrac{36}{20}\\\\=1.8

The average number of pets per family is 1.8.
