Answer:

316 milliliters of compound A

Step-by-step explanation:

We know for every 7milliliters, we have 4 milliliters of compound A and 3 milliliters of compound B

So, take 553 divided by 7 = 79

So, take 4 times 79 = 316 milliliters of Compound A

So, 316 milliliters of Compound A are needed!

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?

Answers

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.

Answer:

By the math, x = 10°

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.

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.
