Answer:
20.3cm^2
Step-by-step explanation:
Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2
Díameter is 2 inches = 5. 08cm
But radius = diameter /2
Radius = 5.08cm /2
Radius = 2.54cm
Hence Area of bulleyse = 3.14 x (2.54) ^2
= 3.14 x 6. 451 cm^2
= 20.256 cm^2
=20.3cm^2 (to nearest tenth)
Answer:
- 39 quarters and 41 nickels
Step-by-step explanation:
Let the number of quarters be x and nickels be y.
<u>Given:</u>
- Quarter is 25 cents
- Nickel is 5 cents
- Number of coins is 80
- Total amount is $11.80 = 1180 cents
<u>We have equations:</u>
- x + y = 80
- 25x + 5y = 1180
<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>
- 25x + 5y - 5x - 5y = 1180 - 80*5
- 20x = 780
- x = 780/20
- x = 39
<u>Find the value of y:</u>
- 39 + y = 80
- y = 80 - 39y = 41
<u>Verify:</u>
- 25*39 + 5*41 = 975 + 205 = 1180
