Write an out an equation using the information given. So:
8 + 5 + x - 2 = 14.5
<span>13 + x - 2 = 14.5 </span>
<span>11 + x = 14.5 </span>
<span>x = 3.50
This means that the answer is D.
Hope this helped :)</span>
Answer:
exponential function, x = time in minutes, y = number of bacteria
Step-by-step explanation:
y = 20 × (2)^x
Answer:
The final temperature of the solution was 5°C
Step-by-step explanation:
we know that
1) At the start of an experiment, the temperature of a solution was -12°C
In this moment the temperature is -12°C
2) During the experiment, the temperature of the solution rose 5°C each hour during 4 hours
so
5°C*4=20°C
In this moment the temperature is -12°C+20°C=8°C
3) The temperature changed by -3°C
In this moment the temperature is 8°C-3°C=5°C
5+7+8=20 which is the total number of balls that the bag contains
because out of the 20 balls only the 8 are blue, it is right to say that
8/20 = x/100 ⇒ x= (8·100)/20 ⇒ x= 800/20 ⇒ x=40
the blue balls are the 40%
In this question we are not told the the measurements of the horse pasture
