Answer:
Gọi AH là đường cao kẻ từ A đến BC
Xét tam giác AHC vuông tại H
Suy ra AH = HC. cotA= 9.cot35° = 12,9
Xét tam giác AHB vuông tại H
Suy ra BH = AH.tanA = 12,9.tan61°=23,37
Ta có BC= HC+ HB= 9+23,27 =32,27
Diện tích tam giác ABC = 1/2 × AH ×BC= 1/2 ×12,9×32,27=208,1415
(3 x 10) x 8 = 3 x (10 x 8)
this is called the associative property of multiplication.
it states : (a * b) * c = a * (b * c)
The fourth choice - 5/104.
In one cube, there are 3 even numbers - 2,4,6. For two cubes, the total probability is 36.
3*3 / 36 = 9/36
For letters, there are five vowels over 26 letters = 5 / 26
Multiply the two probabilities to get the probability of rolling two even numbers and selecting one of the vowels.
9/36 * 5/26 = 5/104

Answer:
- 1656 acres left
- 644 acres sold
- $32,200,000
Step-by-step explanation:
1. The number of acres sold is ...
28% × 2300 = 0.28 × 2300 = 644
Then the number of acres Emmet has left will be ...
2300 -644 = 1656 . . . acres left
__
2. Emmet sold 644 acres.
__
3. At $50,000 per acre, the value of the land sold was ...
$50,000 × 644 = $32,200,000 . . . . paid by the developer
