Answer:

800

Step-by-step explanation:

In order to get the new population of bacteria in <em>690 minutes</em>, you have to know how often the bacteria will divided in the time frame. So, you have to <em>divide </em><em>690 minutes </em><em>by </em><em>230 minutes.</em>

  • 690 min. ÷ 230 min. = 3 times

The bacteria wil<u>l double its colony 3 times in 690 minutes</u>.

  • <em>First division:</em> 100 x 2 = 200 bacteria
  • <em>Second division:</em> 200 x 2 = 400 bacteria
  • <em>Third division:</em> 400 x 2 = 800 bacteria

Therefore, the population of bacteria will be 800 in 690 minutes.

16 tablespoon to milliliters
Brut [27]

Answer:  The answer is: " 240 milliliters (mL) " .

_________________________________________________

Step-by-step explanation:

_________________________________________________

Given 16 Tablespoons ;  Convert to "mL" .

Note:  "milliliters" can be abbreviated as "mL" .

Note:  15 mL = 1 Tablespoon .


16 Tablespoons * (\frac{15 mL}{1 Tablespoon})  ;

            = (16 * 15)  mL  

            =   240 mL .

_________________________________________________

The answer is:  " 240 milliliters (mL) " .

Given that the mass of an average linebacker at Ursinus College is 250 lbs and the radius of a pea is 0.50 cm, calculate the num
Brilliant_brown [7]

Answer:

1.544*10⁹ Linebackers would be required in order to obtain the same density as an alpha particle

Step-by-step explanation:

Assuming that the pea is spherical ( with radius R= 0.5 cm= 0.005 m), then its volume is

V= 4/3π*R³ = 4/3π*R³ = 4/3*π*(0.005 m)³ = 5.236*10⁻⁷ m³

the mass in that volume would be  m= N*L (L= mass of linebackers=250Lbs= 113.398 Kg)

The density of an alpha particle is  ρa= 3.345*10¹⁷ kg/m³ and the density in the pea ρ will be

ρ= m/V

since both should be equal ρ=ρa , then

ρa= m/V =N*L/V → N =ρa*V/L

replacing values

N =ρa*V/L = 3.345*10¹⁷ kg/m³ * 5.236*10⁻⁷ m³ /113.398 Kg  = 1.544*10⁹ Linebackers

N=1.544*10⁹ Linebackers

2. A lunch stand makes s.75 profit on each chef's salad and $1.20 profit on each Caesar salad. On a typical weekday, it sells be
kow [346]

Let's let

<u>x = the number of chef salads, x>=0</u>

<u>y = the number of Caesar salads, y>=0</u>

The constrains are:

40 <= x <= 60

35 <= y <= 50

x + y <= 100

The objective function here is F(x, y) = 0.75x + 1.20y

The corner points are (40, 35),  (60, 35), (60, 40), (50, 50) and (40, 50).

F (40, 35) = 0.75*40 + 1.20*35 = $72

F (60, 35) = 0.70*60 + 1.20*35 = $84

F (60, 40) = 0.75*60 + 1.20*40 = $93

F (50, 50) = 0.75*50 + 1.20*50 = $97.50

F (40, 50) = 0.75*40 + 1.20*50 = $90

Thus, we conclude to maximize the profit 50 Chef and 50 Caesar salads should be prepared.

What is the x please answer me quick ​

First u do a squared +b squared =c squared aka pythagorean theorem then so u already have c squared so you would do 5x5=25 and 13x13=169 so then the equation would be 25+?=169 then do 169-25 which equals 144 and then do the square root of that which is 12 THE ANSWER IS 12
