Answer:
10
Step-by-step explanation:
AB + BC = AC and AC = 14
x + 15 + 2x + 32 = 14 add like terms
3x + 47 = 14 subtract 47 from both sides
3x = -33 divide both sides by 3
x = -11 now the length of BC
2x + 32 replace x with -11
2*(-11) + 32 = 10
Answer:
27in
Step-by-step explanation:
So, perimeter means we add all the sides together, as opposed to area, where we multiply them together.
9 - 5 = 4.
So the perimeter of the triangle would be:
3+4+
=12
5 + 5 + 4 +1 (the 1 is from 4 -3) = 15
15 + 12 = 27
Answer:
0.341
or 1.0723
Step-by-step explanation:
the volume of hemisphere = (2/3)

r = (1/2)d = 0.8
(2/3)
= 0.341
= 1.0723
Answer: 156
Step-by-step explanation:
80 x 195% = 156
OR
80 x 1.95 = 156
