Answer:
11 cm
Step-by-step explanation:
The volume of the prism is given by the formula ...
V = Bh
where B is the area of the triangular base, and h is the height.
Filling in the given information, we find the area of the triangular base to be ...
726 cm³ = B(12 cm)
B = 726 cm³/(12 cm) = 60.5 cm²
The area of an isosceles right triangle is half the area of a square with the same side lengths:
B = 1/2s²
60.5 = 1/2s²
s = √(2(60.5)) = √121 = 11
The length of each of the equal sides of the base is 11 cm.
The answer is D.

Answer:
4200 with 35% markdown: 2730
5000 with 44% markdown: 2800
Step-by-step explanation:
To calculate the price of an item including the markdown, multiply the original price by (1 minus markdown).
Convert the markdown percentage to decimal form before subtracting.
4200 with a 35% markdown: (35% = 0.35)
4200*(1 - 0.35)
= 4200 *(0.65)
= 2730
5000 with a 44% markdown: (44% = 0.44)
5000*(1 - 0.44)
= 5000*(0.56)
= 2800
Therefore, the sale price for $4200 with a 35% markdown is $2730, and the sale price for $5000 with a 44% markdown is $2800.
