A pile of 42 coins worth $4.90, consisting of nickels and quarters. How many nickels are there?
Ymorist [56]

Answer:14

Step-by-step explanation:

A nickel is 5 cents (20% of dollar)

and a quarter is 25 cents (25% of dollar)

We have given a pile of 42 coins worth of $4.90

Let x be the no nickels and

y be the no of quarter

therefore

x+y=42    -----1

\frac{x}{4}+\frac{y}{20}=4.90 ---2

Solving \left ( 1\right )&\left ( 2\right ) we get

x=14 & y=28

Therefore no of nickels is 14 & no of quarters is 28

Diameter Radius Area Circumference of= 132
AveGali [126]

Answer:

lets \:  \: find \:  \:  \: the \:  \:  \: radius \\ 2\pi \: r = 132 \\   \frac{2\pi \: r}{2\pi}  =  \frac{132}{2\pi}  \\ r = 21.01

lets \:  \:  \: find \:  \:  \: the \:area \: now \\  = \pi {r}^{2} \\  = \pi \times  {21.01}^{2}   \\  = 1,386.76

lets \: fin d\:  \:  \: the \:  \: diameter \\  = d = 2r \\ =  d = 2 \times 21.01 \\  = d = 42.02
