Answer:
50.27 cm²
Step-by-step explanation:
Subtract the area of the smaller circle from the area of the larger circle
The area of a circle = πr² ( r is the radius )
area = π × 5² - π × 3² = 25π - 9π = 16π ≈ 50.27 cm² ( nearest hundredth )
This is the anwser to your equation
Let tomatoes be as x and corn be as y.
Total cans is 36 cans.
$20.8 = 2080 cents
1. x + y = 36
2. 80x + 40y = 2080
From equation 1, we get
y = 36 - x
Substitute into equation 2,
80x + 40(36 - x) = 2080
80x + 1440 - 40x = 2080
40x = 2080 - 1440
x = 640 ÷ 40
x = 16
x + y = 36
16 + y = 36
y = 36 - 16
y = 20
Alex does buy 16 tomatoes.
Answer:
15
Step-by-step explanation:
The price of the bag at the pharmacy is
2/3 * 12 = 8 dollars
You have enough for 10 at the gift shop
10 * 12 = 120
Take 120 dollars and divide by 8 dollars to see how many you can get at the pharmacy
120/8 =15
