Answer: $3,168
Step-by-step explanation:
Paulo sells 249 medium pumpkins for $8 each. The money Paulo makes from this is:
= 249 * 8
= $1,992
Paulo also sells 84 large pumpkins for $14. The money made is:
= $1,176
Total from selling both is:
= 1,992 + 1,176
= $3,168
Answer:
x = -15,46 thì y ≈ 34,46
x = 2,46 thì y ≈ 16,54
Step-by-step explanation:
x + y = 19 => x = 19 - y (1)
thay x = 19 -y vào phương trình 11x + x^2 = 2y ta có:
11 * (19 - y) + (19 - y)^2 =2y
=> 209 - 11y + 361 - 38y + y^2 = 2y
=> y^2 - 51y + 570 = 0
=> y ≈ 34,46 và y≈16,54
thay y ≈ 34,46 vào phương trình (1) có:
x = 19 - 34,46 = -15,46
thay y ≈ 16,54 vào phương trình (1) có:
x = 19 - 16,54 = 2,46
The entire circle has a central angle of 360°.
Because the radius is 6 mi, the area of the circle is
π(6)² = 36π mi².
The sector has a central angle of 60°, therefore it occupies 60/360 = 1/6 of the area of the circle.
The area of the sector is
(1/6)*36π = 6π mi² = 18.85 mi²
Answer: 6π mi² or 18.85 mi².
Answer:
