A bowl of spaghetti contains 5 grams of fiber. It is recommended for a person to eat 34 grams of fiber in a day. If you ate 3.5

puteri [66]

Answer: 51 %

Step-by-step explanation:

3.5 * 5 = 17.5

17.5 = x/100 * 34

17.5 = 34x/100

17.5 * 100 = 34x

1750 = 34x

x = 1750/34

x = 51.47

rounded to 51%

After breaking your penny bank, you notice that you have $4.87 in quarters ($0.25), dimes ($0.10), nickels ($0.05), and pennies

ira [324]

Answer: Option 'c' is correct.

Step-by-step explanation:

Let the number of dimes be 'x'.

Let the number of nickels be ' $\dfrac{3}{2}x$ '.

Let the number of pennies be $\dfrac{3}{2}\times 2x=3x$

Let the number of quarters be '3x-34'.

As we know that

1 quarter = $0.25

1 dime = $0.10

1 nickel = $0.05

1 penny = $0.01

According to question, we get that

$0.10x+0.05\times \dfrac{3x}{2}+0.01\times 3x+0.25(3x-34)=4.87\\\\0.10x+0.075x+0.03x+0.75x-8.5=4.87\\\\\\0.955x=4.87+8.5\\\\0.955x=13.37\\\\x=\dfrac{13.37}{0.955}\\\\x=14$
