Answer:
65.8 ft
Step-by-step explanation:
The number of strings required to tie each vertex to the other three will be ...
(4)(3)/2 = 6
Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.
d² = 12² +7² = 144 +49 = 193
d = √193 ≈ 13.892
Then the total length of all strings is ...
L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet
The artist will need 65.8 feet of string.

Answer:
b)−2° C
Step-by-step explanation:
hello! To solve this problem you should remember how are the operations with negative numbers, for this the only thing we must do is make a subtraction between the initial temperature (8° C) and the negative change of temperature (10° C)
Ti= initial temperature =8° C
ΔT= temperature change =10° C
new temperature=Ti-ΔT
new temperature=8° C-10° C=-2° C
in conclusion the answer is -2° C
