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:
(x,y) across the y axis is (-x,y)
Step-by-step explanation:
When reflected across the y-axis, the x coordinate in the opposite.
(X+5)²=4/4
X+5=1, X+5=-1
X=1-5 X=-1-5
X=-4 X=-6
the inequality goes from -30 and all number up but not including -30 because it has open circle. so mark all number greater than -30
Answer: D) 6.0 hours
Step-by-step explanation:
The destination is 420 mi away, and you're travelling at 70 mph. This means you travel 70 miles every hour. This leads to 420÷70, which is 6. The answer is 6 hours.
