A culture of bacteria has an initial population of 970 bacteria and doubles every 7
hours. Using the formula P+ = Po.2, where P is the population after t hours, Po
is the initial population, t is the time in hours and d is the doubling time, what is the
population of bacteria in the culture after 2 hours, to the nearest whole number?
Answer:1182.4432≈1182
Step-by-step explanation:
The population of bacteria in the culture after 2 hours is approximately 1,248.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Given that the initial population of bacteria is [tex]P_0[/tex] = 970, and the doubling time is d = 7 hours.
Using the formula,
P+ = [tex]P_0[/tex] x [tex]2^{t/d)[/tex]
We can calculate the population of bacteria after 2 hours as follows.
P+ = 970 x [tex]2^{2/7}[/tex]
= 1,248.4
Rounding this to the nearest whole number, the population of bacteria in the culture after 2 hours is approximately 1,248.
Thus,
The population of bacteria in the culture after 2 hours is approximately 1,248.

Rosa is making a game board that is
16 inches by 24 inches. She wants to
use square tiles. What is the largest
tile she can use?
Please show working
Answer:
8" by 8"
Six of those will fit on the board
Step-by-step explanation:
Answer:
The largest tile she can use is a 8 inches by 8 inches tile.
Step-by-step explanation:
Rosa is making a game board that is 16 inches by 24 inches.
She wants to use square tiles.
The area of the game board (area of a rectangle) is equal to length times width.
∴ Area = 16 inches × 24 inches = 384 square inches
The prime factors of 384 are; 2^7 × 3
We can put it as;
2^6 × 6 = 384
The square root of 2^6 is 2^3 = 8
So Rosa will need six square tiles of 8 inches by 8 inches each.
Hence the largest tile she can use is a 8 inches by 8 inches tile.
You can buy a 6 back of Gatorade for $4.99 or you can buy 1 for $0.89. Which is
the better buy?
6 for $4.99
1 for $0.89
Answer: 6 for $4.99
Step-by-step explanation: You would be better off buying 6 for $4.99 because the unit rate of each bottle is cheaper. You can find the unit rate by dividing 4.99 by 6 which equals .83
If you were to buy 6 for .89 you would end up spending $5.34.

What is the solution to the equation p + 7.2 = 11?
p = 3.2
p = 3.8
p = 4.8
p = 18.2
Answer:
p = 3.8
Step-by-step explanation:
11 - 7.2 = 3.8
Answer:
p = 3.8
Step-by-step explanation:
We have the equation p + 7.2 = 11 and are asked to solve for "p".
To do so, all we need to do is isolate p :
p + 7.2 = 11
Subtract 7.2 from both sides :
p = 3.8

The value of the expression 21 ÷ 3 + (8 - 2 ÷ 2) is 14.
To simplify the expression 21 ÷ 3 + (8 - 2 ÷ 2).
we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.
The expression inside the parentheses should be solved first.
8 - 2 ÷ 2.
First, divide 2 by 2, which equals 1.
Then, subtract 1 from 8: 8 - 1 = 7.
Now, we have 21 ÷ 3 + 7.
Divide 21 by 3, which equals 7.
Finally, add 7 + 7, which equals 14.
Therefore, the simplified expression 21 ÷ 3 + (8 - 2 ÷ 2) equals 14.

the shape of the toy is a cylinder of radius 5 cm and height 8 cm on top of a hemisphere of radius 5cm calculate the volume of a toy
Answer:
889.66 cm^3
Step-by-step explanation:
here's your solution
=> radius of cylinder = 5 cm
=> height of cylinder => 8 cm
=> radius of hemisphere = 5 cm
=> volume of toy = ( vol of cylinder + vol of hemisphere)
=> volume of cylinder = πr^2h
=> putting value , = 22/7*5*5*8
=> volume = 628 cm^3
=> volume of hemisphere = 2/3πr^3
=> putting value , = 2/3*22/7*5^3
=> volume of hemisphere = 261.66 cm^3
=> volume of toy = (628 + 261.66)cm^3
=> volume = 889.66 cm^3

"when you are dealing with absolute values got to be really careful about what your final step looks like.
So when you isolate your absolute value bars, if you have the absolute value of something we know this can be positive is greater than a negative number your golden cuz a positive number is always going to be greater than a negative number. But if you end up with an absolute value of something and it's less than a negative number that's never going to be true because _______________

Absolute value is the distance from zero, it doesnt matter if its -58 or 58 its absolute value is always going to be positive, so if you have a negative just get rid of that negative sign. Absolute value makes it all positive -492= 492 in absolute value.
