Researchers recorded that a group of
irakobra [83]

Answer:

The number of bacteria grown in 35 hours is 15771

Step-by-step explanation:

It is given that,

Researchers recorded that a group of bacteria grew from 100 to 7,000 in 14 hours.

Therefore, the bacteria has grown from 100 to 7000 in 14 hours.

To calculate number of bacteria grown in 14 hours :

⇒ 7000 - 100 = 6900

6900 bacteria grows in 14 hours. We need to find out the growth of bacteria in 1 hour in order to calculate its growth in 32 hours.

To calculate number of bacteria grown in 1 hour :

⇒ Total bacteria growth in 14 hours / 14

⇒ 6900 / 14

⇒ 492.85

To calculate number of bacteria grown in 32 hours :

⇒ 492.85 × 32

⇒ 15771.2

⇒ 15771  (rounded to nearest whole number)

∴ The number of bacteria grown in 32 hours is 15771

Hope this answer helps you :)

Have a great day

Which is the correct way to evaluate the expression 48 - (29-17)
Nadusha1986 [10]

Answer:

The correct way to evaluate this expression is my following the order of operations PEMDAS

P=Paranthesis

E=Exponents

M/D=multiply/divide

A/S=add/subtract

The first step in 48-(29-17) is to do what's inside the paranthesis

48-12 (29-17=12)

Then you would subtract 48-12

48-12=36

Your final answer is

36

Hope this helps ;)

Determine the astm grain size number if 33 grains per square inch are measured at a magnification of 270×
strojnjashka [21]
8.9

The equation for the grain size is expressed as the equality:
Nm(M/100)^2 = 2^(n-1)
where
Nm = number of grains per square inch at magnification M.
M = Magnification
n = ASTM grain size number

Let's solve for n, then substitute the known values and calculate.
Nm(M/100)^2 = 2^(n-1)

log(Nm(M/100)^2) = log(2^(n-1))
log(Nm) + 2*log(M/100) = (n-1) * log(2)
(log(Nm) + 2*log(M/100))/log(2) = n-1
(log(Nm) + 2*log(M/100))/log(2) + 1 = n

(log(33) + 2*log(270/100))/log(2) + 1 = n
(1.51851394 + 2*0.431363764)/0.301029996 + 1 = n
(1.51851394 + 0.862727528)/0.301029996 + 1 = n
2.381241468/0.301029996 + 1 = n
7.910312934 + 1 = n
8.910312934 = n

So the ASTM grain size number is 8.9

If you want to calculate the number of grains per square inch, you'd use the
same formula with M equal to 1. So:
Nm(M/100)^2 = 2^(n-1)
Nm(1/100)^2 = 2^(8.9-1)
Nm(1/10000) = 2^7.9
Nm(1/10000) = 238.8564458
Nm = 2388564.458

Or about 2,400,000 grains per square inch.
