10 quarters 17 dimes 40 nickels 15 pennies answer
Oliga [24]

If the given quantities are 10 quarters 17 dimes 40 nickels 15 pennies then the total money would be 6.35 dollars.

<h3>What is the fundamental principle of multiplication?</h3>

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Quarters are worth .25 of a dollar

10 x .25 = 2.5

Dimes are worth .10 of a dollar

17 x .10 = 1.7

Nickels are worth .05 of a dollar

40 x .05 = 2

Pennies are worth .01 of a dollar

15 x .01 =  0.15

Add this together

2.5 + 1.7 + 2 + 0.15

= 6.35

Solve by completing the square. x^2 + 4x – 1= 0
NNADVOKAT [17]

Answer:

x = -2 ± sqrt(5)

Step-by-step explanation:

x^2 + 4x – 1= 0

Add 1 to each side

x^2 + 4x – 1+1= 0+1

x^2 +4x = 1

Take the coefficient of x

4

Divide by 2

4/2 =2

Square it

2^2=4

Add it to each side

x^2 +4x+4=1+4

(x+2)^2 = 5

Take the square root of each side

sqrt((x+2)^2 )=± sqrt(5)

x+2 = ± sqrt(5)

Subtract 2 from each side

x+2-2 = -2 ± sqrt(5)

x = -2 ± sqrt(5)

PLEAS HELP ASAP PLEAS 20 points<br> 1 over 3b = 4 over 5. what equals b in this equation?
White raven [17]

Answer:

b = 5/12

Step-by-step explanation:

You have the proportion

1/(3b) = 4/5        

Cross multiply to get rid of the fractions...

5 = 12b                now solve for b

5/12 = b                 (divide by 12 on both sides)
