A group of five people are all working on the same mathematics problem. On the night before it is due, they call each other to d

UkoKoshka [18]

Answer:

Minimum number of calls = 10

Step-by-step explanation:

Lets name the five people as A,B,C,D and E.

On the night before ,each person talks to every other person atleast once that means A would talk to B,C,D and E atleast once.

Lets start with A. He would talk to other 4 people which means there would be 4 phone calls made.

Now lets take B. He can talk to A,C,D and E. But A has already talked to C therefore to get minimum number of phone calls , B need not call A again. So he calls only C,D and E.

In case of C using similar logic he need to talk to only D and E.

For D , he talks to E alone.

E does not have to talk to anyone as he has already talked to everyone atleast once.

Total calls = 4 + 3 + 2 + 1

= 10

A softball coach has ordered softballs for two different leagues. The Junior League uses

dedylja [7]

The number of 11-inch softball is 70 and the number of 12-inch softball is 50.

Step-by-step explanation:

Given that,

The cost of 11-inch softball = $2.50
The cost of 12-inch softball = $3.50

Let us assume,

The number of 11-inch softball be 'x'.
The number of 12-inch softball be 'y'.

Forming the equation to solve x and y values :

The total number of softball ordered = 120
The total cost for 120 softballs = $350

x + y = 120 -------(1)

2.5x + 3.5y = 350 --------(2)

Multiply eq(1) by 2.5 and subtract eq(2) from eq(1),

2.5x +2.5y = 300

-(2.5x +3.5y = 350)

-1y = -50

Therefore the value of y = 50.

The number of 12-inch softball is 50.

Substitute y=50 in eq(1),

x+50 = 120

x = 120-50

x = 70

The number of 11-inch softball is 70.
