Answer:
29000 - 24360 = $4,640
Step-by-step explanation:
Steps:
Answer: 7000 degrees per second
<span>X= -0.083….. as
fraction.
=> x = -0.083…
=> Let 10x = -0.83
Therefore, 10x and x = -8.3… and -0.083….
Now let’s subtract both number
=> 9x = -7.47 (let’s round off -7.47 to 7.5)
=> 9x = - 7.5 ( fraction of -7.5 = -15/2)
=> 9x = 15/2
=> x = 16/18
=> therefore x= 16/18 or 5/6</span>
She started off with $7.
Add $25 $18 $50 you get 93.
Minus 86.
$7.
First you need to find the area of the plate.
The formula for the area of a circle is Area = pi *r^2
The radius (r) is given as 6 inches.
We will use 3.14 for pi
Area = 3.14 x 6^2
Area = 3.14 x 36
Area = 113.04 square inches.
Now to find the density, divide the total bacteria by the area:
Density = 120,000 / 113.04 = 1061.57 which rounds up to 1,062 bacteria/ square inch.
