Answer 1

Function:

f(x) = 30x (75%) + 1

Bacteria after 2 hours:

10,890 bacteria

Answer 2

Answer:

I'm not sure about the function but here is the answer: 3

Step-by-step explanation:

Well, 75% of 1 is 0.75 + 75% of that + 75% of that and so on until you do it four times. Why four? Well it increases every 30 MINUTES so 30 min + 30 min + 30 min + 30min = 2 hours!

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y

Answers

Answer:

The value of x is 2.

The value of y is [tex]\frac{7}{6}[/tex]

Step-by-step explanation:

We have that:

[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]

Multiplying everything by 3

[tex]x + 3 = 5[/tex]

[tex]x = 2[/tex]

The value of x is 2.

We have that:

[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]

Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.

[tex]6y - 4 = 3[/tex]

[tex]6y = 7[/tex]

[tex]y = \frac{7}{6}[/tex]

The value of y is [tex]\frac{7}{6}[/tex]

A 4-story building is 29 feet tall. Between which two whole numbers does the height of each story lie?

Answers

Answer:

7 & 8

Step-by-step explanation:

29÷4=7.25

7<7•25<8

The inequality of the height of the building is given by 7 < A < 8 , where A is the height of the building = 7.25 feet

Given data ,

A 4-story building is 29 feet tall

So , the height of the each story is given by the equation ,

To determine the height of each story in a 4-story building, we divide the total height of the building (29 feet) by the number of stories (4).

A = 29/4

On simplifying the equation , we get

29 feet ÷ 4 stories = 7.25 feet per story

Now , the inequality representing the height of the building between the whole numbers is given by

7.25 lies between 7 and 8

So , the inequality is 7 < A < 8

Hence , the height of each story in the 4-story building lies between 7 feet and 8 feet

Simplify: 14ba2+21ab2−ab2.

Answers

14ba^2+20ab^2 because you subtract one from 21ab^2

The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².

What is simplification?

In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.

The expression is given in the question, as follows:

14ba²+21ab²−ab²

When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².

Thus, the given expression can be simplified to 14ba²+20ab².
