Answer:
A. 64 square units
Step-by-step explanation:
The area of a triangle is denoted by: A = (1/2) * bh, where b is the base and h is the perpendicular height to the base.
Here, we can say that side AB is the base with length 10, while the perpendicular segment extending from C to AB with length 12.8 is the height. Then, plug these in:
A = (1/2) * bh
A = (1/2) * 10 * 12.8 = 5 * 12.8 = 64
The answer is thus 64 square units, or A.

Answer:
5 friends
Step-by-step explanation:
To find out how many friends she gave cany, you must divide the number of candy total by how many pieces each friend got.
Therefore-
30 divided by 6 = 5
The answer is 5
Divide 243 by 3:
243 / 3 = 81
Subtract the exponents:
8-2 = 6
So you have 81 x 10^6
Now move the decimal point on 81 to have one digit to the left of the decimal point and then add the number of moves to the exponent.
81 becomes 8.1, and you moved the decimal 1 place, so add 1 to the ^6:
Answer is 8.1 x 10^7
Answer:
The slope between the two given point is -1
Step-by-step explanation:
The rule of the slope between two points (x1, y1) and (x2, y2) is
m = 
Let us use this rule to solve the question
∵ The given points are (-2, 9) and (1, 6)
∴ x1 = -2 and y1 = 9
∴ x2 = 1 and y2 = 6
→ Substitute them in the rule of the slope above
∵ m = 
→ Remember (-)(-) = (+)
∴ m = 
∴ m = 
→ Divide up by down
∴ m = -1
∴ The slope between the two given point is -1
