Answer:

english:Two is a prime because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two. That leaves only the odd numbers. Of course, not all odd numbers are prime (e.g. nine is divisible by three).

your language sry idk WATS it is not trying to be rude or anything like that oh its Spanish just figured it out here it is

Step-by-step explanation:Dos es primo porque es divisible entre solo dos y uno. Todos los demás números pares no son primos porque todos son divisibles por dos. Eso deja solo los números impares. Por supuesto, no todos los números impares son primos (por ejemplo, nueve es divisible por tres).

Henrietta did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the bacteria cells was 5

poizon [28]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have a exponential function of the form

$y=a(b^x)$

where

y ---> is the population of bacteria

x ---> the number of hours

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate of change

b=(1+r)

we have

$a=700\ bacteria$

$r=5\%=5/100=0.05$

$b=1+0.05=1.05$

substitute

$y=700(1.05^x)$

For x=20 hours

substitute in the equation and solve for y

$y=700(1.05)^{20} =1,857\ bacteria$

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes)

saw5 [17]

Answer: $19.6

Step-by-step explanation:

Linear function: f(x)=mx+c

, where m= rate of change in f(x) with respect to x.

c = Initial value.

Let c = Initial value of card , m= Charge per minute

x= Number of minutes calling time.

Then, 25.06= 38m+c (i)

21.03=69m+c (ii)

Eliminate (ii) from (i)

$4.03=-31m\\\\\Rightarrow\ m=\dfrac{4.03}{-31}\\\\\Rightarrow\ m=-0.13$

Put m in (i) , we get

$25.06= 38(-0.13)+c\\\\\Rightarrow\ 25.06=-4.94+c\\\\\Rightarrow\ c=25.06+4.94\\\\\Rightarrow\ c=30$

i.e. f(x)=-0.13x+30

if x=80 then

f(80)= -0.13(80)+30

=-10.4+30

=19.6

Hence, the remaining credit after 80 minutes of calls = $19.6

The measures angles of hexagon are 4x, 5x, 6x, 7x, 8x and 9x. calculate the size of the largest angle.

ankoles [38]

Answer:

rounded to the nearest whole number = 166

Step-by-step explanation:

Add all of the angles together, to get 39x. In a hexagon, all the angles add up to 720. Divide 720 by 39 to get x, then multiply x by 9, as that is the largest angle to get an answer rounded to the nearest whole number of 166.

If you found this answer helpful, I would appreciate it if you gave me brainliest :D
