Taji has a total of 98 quarters and dimes. their value is $18.20 how many quarters does taji have?
scZoUnD [109]

Answer:

Taji has a total of 56 quarters.

Step-by-step explanation:

Let <em>x</em> be the number of quarters that Taji has.

Amount in terms of quarter =0.25 \times x

Let <em>y</em> be the number of dimes that Taji has.

Amount in terms of quarter =0.10 \times y

As per question statement:

x + y = 98 ...... (1)

Total amount is $18.20 as given in the question statement.

\Rightarrow 18.20 = 0.25 \times x + 0.10 \times y\\\Rightarrow 25x + 10y = 1820 ...... (2)

Solving equations (1) and (2):

Multiplying equation (1) by 10 and subtracting from equation (2):

25x + 10y -10x -10y= 1820 - 980\\\Rightarrow 15x = 840\\\Rightarrow x = 56

<em>x </em>is the number of quarters that Taji has.

So, Taji has a total of 56 quarters.

B)0.2451

C) 0.2549

Step-by-step explanation:

Total number of cards N = 52

A) Number of picture cards including the king, Queen ,jack = 12

P(picture cards) = (12/52)*(11/51)

P(picture cards) = 0.0498

B) Number of red cards ( hearts and diamonds) = 26

P( red cards) = (26/52)*(25/51)

P(red cards) = 0.2451

C) Number of black cards ( Spaders and clubs) = 26

P( one red and one black cards) = (26/52)*(26/51) = 0.2549

Zarrin [17]
Instead of a real language, I'll use pseudo code here: 


var TOTAL_SCORE = 0
for(var x; i<1000; i++) {
      var SCORE rand.random_integer[from 1-10];
      var TOTAL SCORE = TOTAL_SCORE + SCORE;
}

print(TOTAL_SCORE);
