Answer:
$160 hourly rate
Step-by-step explanation:
20 x 5 = 100
900 - 100 = 800
800 ÷ 5 = 160
To check: Multiply 160 by 5 and then add 100
<h2>B is the correct answer!</h2><h3>(There's a chance I might be wrong.)</h3><h3></h3><h3>You have to rotate the shape by 180 degrees to get the other shape. (Sorry, I'm not good at explaining.)</h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3>
Answer: (4, 5)
Work:
Substitute the y in the second problem with y=x+1
3x-2(x+1)=5
3x-2x+1=5
x=4
Now solve for y
y=4+1
y=5
Answer:
B
Step-by-step explanation:
The square root of 21 will be halfway between 4 and 5. 4.58 ~ 4.6
The square root of 17 will be closer to 4 than 5. 4.12 ~ 4.1
3Pi/2 will beclose to 5 than 4. 4.71 ~ 4.7
4.1, 4.6, 4.7
That is B.
Starting with N = N₀·(1+r)^(t/4)
where N is the number of bacteria at t hours, r is the growth rate, and N₀ is the initial number of bacteria
N₀ = 64
r = 50% = 0.5
So the formula is:
N = 64 · (1+0.5)^(t/4)
N = 64·(1.5)^(t/4)
So after 100 hours,
N = 64 · (1.5)²⁵ = 1.6×10⁶
There are 1.6×10⁶ bacteria at 100 hours.
