Answer:
x=38
×= 90÷4( divide it to get the answer)
Answer:wo consecutive integers would be 13 and 14 because 13 x 13 = 169 and 14 x 14 = 196 and the inequality fits inbetween perfectly.
Step-by-step explanation:
Given that the hall is rectangular in shape, then the shortest path that Amy must travel to reach Alice would be through the hall's diagonal.
Applying the Pythagorean theorem, with the length and width as the legs and the diagonal as the hypotenuse of the right triangle. Thus,
diagonal = √ ( 100² + 60²) = √13 600 ≈ 116.62 ft
The shortest distance, rounded off to the nearest foot, is 117 ft<span>. </span>
Answer:
3137
Step-by-step explanation:
The decay factor is 400/110,000 = 1/275 in 30 hours. Assuming an exponential decay, the equation for the number remaining can be ...
n(t) = 110,000·(1/275)^(t/30)
Then after 19 hours, the number remaining is ...
n(19) = 110,000·(1/275)^(19/30) ≈ 3137
There will be about 3137 bacteria after 19 hours.
The answer would be C) 0.26
