Answer:
1/12 mile
Step-by-step explanation:
We can use a ratio to solve
7/12 miles x miles
---------------- = ---------------
7 minutes 1 minute
Using cross products
7 /12 * 1 = 7x
Divide each side by 7
7/12 * 1/7 = x
1/2 = x
<span>The numbers that are a distance of 1/2 unit from 3/5 on a number line are the numbers that are 1/2 units to the right and to the left of 3/5 on the number line.
The numbers are given by 3/5 - 1/2 and 3/5 + 1/2.
The numbers are 1/10 and 1 1/10

Answer:
The bacterial culture loses
of its size every 7 seconds.
Step-by-step explanation:
The relationship between the elapsed time t, in seconds, and the number of bacteria, N(t), in the petri dish is modeled by the function:

Since the growth factor is less than 1, it is a decay equation.

Observe that the time t is divided by 7.
This is the period.
We can therefore say that the bacterial culture loses
of its size every 7 seconds.

1099.99x 0.58 =637.9942
1099.99-637.9942= 461.9958
461.9958x 0.065=30.029727
461.9958-30.029727=431.967073
The answer round is 431.96

42.95x1/5= 8.59
42.95-8.59 = 34.56
34.56 x 0.07=2.4192
34.56-2.4192= 32.1408
Round it is 32.14
