Answer:
First is not a part. second is a part
Step-by-step explanation:
So, what you want to do in this question is plug the value of k=8 into the inequality and see if it is still true.
For the first one,
5(8)<39
40<39, which is not true
For the second one,
8/2 ≤ 4
4≤ 4, which is true
Answer:
458
Step-by-step explanation:
There are only 4 3-digit numbers that have a 5 in the ten’s place and the one’s place is twice of the hundreds place.
152, 54, 356, and 458
If we reverse the order of the digits, we see that 458 becomes 854.
854-458=396
Start with trying to figure out rate (r):
P = i•e^rt
5200 = 4000•e^(r•7)
5200/4000 = 1.3 = e^7r
ln 1.3 = ln (e^7r)
.262 = 7r•1, because the ln (e) = 1
r = .262/7 = .0375
Now that you have the rate, plug in that for r and 9 hours as the new t, with again our 4200 as the i
P = i•e^rt = 4200•e^(.0375•9)
P = 4200•1.401 = 5,886 bacteria
Answer:
Step-by-step explanation:
<u>Question 1</u>
Two isosceles triangles with repeat 72°.
- x = 180° - 2*72°
- x = 180° - 144°
- x = 36°
<u>Question 2</u>
Isosceles triangle with repeat x/2 angle and a x angle.
- 2(x/2) + x = 180°
- 2x = 180°
- x = 90°
