Answer:
- base area: 21 ft²
- volume 105 ft³
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = (1/2)bh
The base and height of a right triangle can be taken to be the leg lengths, since each is perpendicular to the other.
A = (1/2)(6 ft)(7 ft) = 21 ft² . . . . base area
__
The volume is the product of the base area and the height:
V = Bh
V = (21 ft²)(5 ft) = 105 ft³ . . . . volume
Answer:
Its A

Answer:
.36666667
Step-by-step explanation:
A dilation occurs when the scale is greater than 1 from the center of the dilation. When the scale is less than 1 from the center it is a contraction. Since distance from center can be positive or negative, the contraction will occur with a scale factor of
B. -0.8 and
D. 0.8
Really, we don't need to use that much math--we can use logic instead. Since the two congruent sides must be longer than 30in, the total has to be greater than 60in (the longest side plus the congruent sides.) So for our answer, we want the smallest total that is above sixty, which in this case is 72.44in.
Hope I helped, and let me know if you have any questions :) I can explain the real math if you want, it was just unnecessary here.
