Select the correct answer.
A scientist is studying the population growth rates of two different types of bacteria under the same laboratory conditions. The number of
bacterial cells of type A is represented by the equation shown, where Prepresents the number of bacterial cells at the end of x hours.
P = 2 + 19
The number of bacterial cells of type B is represented by the equation shown, where Q represents the number of bacterial cells at the end of
x hours
Q = 3+ 18
Which statement is true?
OA
At the end of 3 hours, there will be the same number of bacterial cells of type A and type B.
B. At the end of 21 hours, there will be the same number of bacterial cells of type A and type B.
C. At the end of 1 hour, there will be the same number of bacterial cells of type A and type B.
D. At the end of 18 hours, there will be the same number of bacterial cells of type A and type B.

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

i have no clue what you just said. write a question in english?

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
