Anit [1.1K]

Answer:

x is 4.30 and 0.697

Step-by-step explanation:

Quadratic formular:

x =  \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a}  \\

a » 1

b » -5

c » 3

x =  \frac{ - ( - 5)± \sqrt{ {( - 5)}^{2}  - (4 \times 1 \times 3)}  }{(2 \times 1)}  \\  \\ x =  \frac{5± \sqrt{13} }{2}

Therefore, values of x :

x =  \frac{5 +  \sqrt{13} }{2}  \:  \: and \:  \:  \frac{5 -  \sqrt{13} }{2}  \\  \\ x = 4.30 \:  \: and \:  \: 0.697

Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have?
saul85 [17]

Answer:

<em>3n; 2 nickels and 6 quarters</em>

Step-by-step explanation:

"Peggy had three times as many quarters as nickels."

Whatever number of nickels she has, the number of quarters is 3 times as many.

Since she has n nickels, she has 3 times n quarters.

The number of quarters is 3n.

A nickel is worth $0.05, so n nickels are worth 0.05n.

A quarter is worth $0.25, so 3n quarters are worth 0.25(3n).

0.05n + 0.25(3n) = 1.60

0.05n + 0.75n = 1.6

0.8n = 1.6

n = 2

She has 2 nickels.

3n = 3(2) = 6

She has 6 quarters.

jok3333 [9.3K]

Answer:

142.5, rounded to 143 women.

Step-by-step explanation:

A squadron with 750 members is the common multiple of the sum of 19 and 81.

Therefore, the number of women in a squadron is equal to [750 : (19 + 81)] x 19 = 142.5.
