A collection of dimes and quarters is worth $10.45. There are 70 coins in all. Find how many of each there are
Advocard [28]

There are 47 dimes and 23 quarters.

Step-by-step explanation:

Total amount = $10.45 = 10.45*100 = 1045 cents

Total coins = 70

1 dime = 10 cents

1 quarter = 25 cents

Let,

Dimes = x

Quarters = y

According to given statement;

x+y=70   Eqn 1

10x+25y=1045   Eqn 2

Multiplying Eqn 1 by 10;

10(x+y=70)\\10x+10y=700\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(10x+25y)-(10x+10y)=1045-700\\10x+25y-10x-10y=345\\15y=345

Dividing both sides by 15;

\frac{15y}{15}=\frac{345}{15}\\y=23

Putting y=23 in Eqn 1

x+23=70\\x=70-23\\x=47

There are 47 dimes and 23 quarters.

A collection of 8 geodes has a mean weight of 14 ounces. A different collection of 12 geodes has a mean weight of 9 ounces. What
labwork [276]

Answer:

The mean weight of the 20 geodes is 11 ounce.

Step-by-step explanation:

Mean weight:

Mean weight is actually the average weight. Add up all weight, then divides by the number objects.

\textrm{Mean weight}=\frac{\textrm{Total weight}}{\textrm{Total number of objects}}

Given that,

A collection of 8 geodes has mean weight of 14 ounce.

Then the total weight of 8 geodes is =(8×14) ounce

                                                             =112  ounce

A different collection of 12 geodes has a mean weight of 9 ounce.

Then the total weight of 8 geodes is =(12×9) ounce

                                                             =108  ounce

Therefore total weight of (12+8) =20 geodes is = (112+108) ounce

                                                                              =220 ounce

The average mean of 20 geodes is

=\frac{220}{20}

=11 ounce.

The mean weight of the 20 geodes is 11 ounce.
