Answer: 138.6 in sq
Step-by-step explanation:
the area of a similar polygon will be the scale factor ^ 2 times the original area
This means that the area of G'H'I' is 3^2 * 15.4 = 9 * 15.4 = 138.6
Answer:
Step-by-step explanation:
I would say the answer is 6
6 + 6 than times by two is 24
Answer:
0.53 will not chosen
Step-by-step explanation:
Given weights:
0.58, 0.63, 0.65, 0.53, and 0.61.
Computation:
Mean weight X = [0.58+0.63+0.65+0.53+0.61] / 5
Mean weight X = [3] / 5
Mean weight X = 0.60
Acceptable weight = l x-X l < 0.06
l x-0.60 l < 0.06
So solving inequality
0.54 < x < 0.66
So, 0.53 will not chosen.
Answer:
Step-by-step explanation:
BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.
Now you have two known lengths The third can be found by applying the Pythagorean theorem: BC²+BD²=CD², from which you can establish a numerical value for BC.
