Answer:

4 Nickels

28 dimes


Step-by-step explanation:

What do we know?

1 dime = $0.10 and 1 nickel = $0.05

We can set up an equation that states:

7x (0.10) + x (0.05) = 3.00


Multiplying out we get:

.70x + .05x = 3.00

If you don't like the decimals you can multiply the entire equation by 100 to get rid of them; you would be left with

70x + 5x = 300

Combine the x terms

75x = 300

Divide both sides by 75

x = 4

Now we use this value with our originally given information. We were told that Sally had 7 times as many dimes as she had nickels so

Dimes equal = 7(x) or 7(4) = 28

Nickels equal = x which was 4

We can check this:

28 dimes would equal = $2.80 and 4 nickels would equal $0.20; adding these two amounts together and it equals $3.00

Find the area of a segment of a circle if its arc is 120 degrees and the radius is 3 inches.
Montano1993 [528]

Answer:<u> 9.42 inches</u>, 3π in terms of pi

Step-by-step explanation:

A full circle is 360 degrees, so if the segment has an arc of 120 degrees, it is 1/3 of a regular circle.

To find the area of a circle, we use the equation A = πr^2. In this case, we will divide the equation by 3 because we are only finding 1/ of a circle. So, our equation will be A  = (πr^2)/3.

Using 3.14 for π:

A  = (πr^2)/3.

A = (π3^2)/3

A = (π9)/3

A = 3π

A = 9.42
