Answer:
.85p + 1.45m <= 14
Step-by-step explanation:
You don't want to spend more than 14, but you can spend 14. So the inequality must be less than or equal to. To find the combination of pencils and markers you must multiply their price times the number of pencils. Sorry if this explanation isn't amazing, I know how to do work but not explain my reasoning. :)
Answer:
1
Step-by-step explanation:
.25 is already a rational number as it equals 25/100 and 1/4 simplified
Answer:
Solution given:
angle : 80°
hypotenuse:y=?
opposite=21
we have
Sin 80=
doing crisscrossed multiplication
we get
y=
<u>y=21.32</u>
Gradient = 5
9 = 5 + c
C = 4
Answer:
Y=5x+4
First we need to find k ( rate of growth)
The formula is
A=p e^kt
A future bacteria 4800
P current bacteria 4000
E constant
K rate of growth?
T time 5 hours
Plug in the formula
4800=4000 e^5k
Solve for k
4800/4000=e^5k
Take the log for both sides
Log (4800/4000)=5k×log (e)
5k=log (4800/4000)÷log (e)
K=(log(4,800÷4,000)÷log(e))÷5
k=0.03646
Now use the formula again to find how bacteria will be present after 15 Hours
A=p e^kt
A ?
P 4000
K 0.03646
E constant
T 15 hours
Plug in the formula
A=4,000×e^(0.03646×15)
A=6,911.55 round your answer to get 6912 bacteria will be present after 15 Hours
Hope it helps!
