For number one please do the following....
you will cut the figure into six shapes. You will have two (4 by 3) squares and four (4 by 1 divided by 2) triangles.
Next, you multiply 4 by 3 and get 12 then multiply again and add both of the area of the two squares. the area for the squares is 24 in total.
finally, you will see that the four half figures left make two full figures. then you can multiply 4 times 1 and get 4 . add 4 plus 4 and get 8. 
the area of the figure as a whole is 24 plus 8 which is 36.

For number two please do the following...
you will multiply the length times the width which in this case is 14 times 32
the area for the parallelogram is 448.

For number three please do the following...
you will do something similar to number one

A culture of 1.08×10^15 bacteria is in petri dish A. A culture of 2.7×10^11 bacteria is in petri dish B.

How many times greater is the number of bacteria in petri dish A than petri dish B?

Enter your answer, in standard notation, in the box.

Answers

To find the number of times the bacteria in petri dish A than petri dish B, let us divide.

So, number of times = [tex]\frac{Number of times bacteria in petri dish A}{Number of times bacteria in petri dish B}[/tex]

[tex]= \frac{1.08(10^{15} )}{2.7(10^{11} )}[/tex]

= 0.4 × [tex]10^{4}[/tex]

= 4000

Hence, the number of bacteria in petri dish A is 4000 times the number of bacteria in petri dish B.

how is 2.25 written as a fraction

Answers

2.25 as a fraction is 2 1/4
'There is not much that can be done to figure out how to write 2.25 as a fraction, except to literally use what the decimal portion of your number, the .25, means. Since there are 2 digits in 25, the very last digit is the "100th" decimal place. So we can just say that .25 is the same as 25/100.' -Google

So 25/100 is your answer.

if you forget to bring the book back to the library, you will pay a fine. is this a negation, conjunction, disjuntion, conditional or biconditional?

Answers

I believe it is a conjunction

The sentence is a conditional statement where the payment of a fine depends on forgetting to return the book. Hence the correct option is Option 4 , conditional

The sentence 'if you forget to bring the book back to the library, you will pay a fine' is a conditional statement. In logic and English grammar, a conditional statement is one where the outcome (the consequent) depends on a certain condition (the antecedent). Here, the antecedent is 'if you forget to bring the book back to the library', and the consequent is 'you will pay a fine'. The structure of this sentence follows the 'if (condition), then (result)' pattern typical of standard conditionals.

For example:

If it rains, the picnic will be canceled.If you study hard, you will pass the exam.

In both examples and the original sentence, the outcome is contingent on the condition being met, which is the hallmark of a conditional statement.

Please help with this question! xx

Answers

Step 1 is to find the cost function for any length of wire in inches. Refer to the table and you can see that...
110 inches cost $6.60 so the point (x,y) = (110, 6.60) is on the line
125 inches cost $7.50 so the point (x,y) = (125, 7.50) is on the line

We only need two points form this line. Let's find the slope
m = (y2-y1)/(x2-x1)
m = (7.50-6.60)/(125-110)
m = 0.90/15
m = 0.06

The slope is 0.06 meaning that each additional inch costs $0.06 (6 cents) extra. 
In other words, the cost is 6 cents per inch.

Plug (x,y) = (110, 6.60) and m = 0.06 into the equation below to solve for b. This will get us the fixed cost
y = mx+b
6.60 = 0.06*110+b
6.60 = 6.60+b
6.60-6.60 = 6.60+b-6.60
0 = b
b = 0

So the fixed cost is 0 which makes sense. If you buy 0 inches of wire (i.e. you don't buy anything) then you don't pay anything.

Therefore the cost function is f(x) = 0.06*x which can be written as y = 0.06*x

------------------------------------------------------------------------

We're told that "Emily needs 23 feet of wire" so we need to convert that feet measurement into inches before we can use the function. The reason why is because x is length in inches (not feet).

23 feet = 23 feet * (12 inches/1 foot) = 23*12 = 276 inches
so in short, 23 feet is equivalent to 276 inches

This means x = 276 and y is...
y = 0.06*x
y = 0.06*276
y = 16.56

Emily will spend 16.56 dollars for her wire.

------------------------------------------------------------------------

Andy needs 14 yards. We'll have to convert from yards to feet
14 yards = 14 yards * (3 feet/1 yard) = 14*3 = 42 feet
14 yards = 42 feet

Then convert that feet measurement to inches
42 feet = 42 feet * (12 inches/1 foot) = 42*12 = 504 inches

So overall,
14 yards = 504 inches

Now we can use the function
y = 0.06*x
y = 0.06*504
y = 30.24

Andy will spend 30.24 dollars for his wire.

Side Note: Andy will spend 13.68 dollars extra compared to Emily (since 30.24-16.56 = 13.68). So Andy spends more. Which makes sense given how Andy needs 504 inches of wire compared to Emily's needs of 276 iches of wire.

Change the order and the grouping of the addends so that you can use mental math to find the sum. Then find the sum. 43+39+43+11=

Answers

Final answer:

By applying the commutative property of addition and rearranging the numbers for easier mental calculation, the sum of 43 + 39 + 43 + 11 can be found to be 136.

Explanation:

The question asks to change the order and the grouping of the addends for easier mental calculation, and then to find the sum of 43 + 39 + 43 + 11. By understanding the commutative property of addition, which states that numbers can be added in any order without changing the sum, we can rearrange these numbers for easier addition.

To use mental math effectively, grouping numbers that make round numbers or those that are easier to add can simplify the process. Here, we can group 43 and 43, which are identical, and 39 and 11, which sum up to a round number.

Therefore, by rearranging:

43 + 43 = 86

39 + 11 = 50

Adding these sums together:

86 + 50 = 136

By changing the order and grouping of the addends, we find that the sum is 136.

14+3n=8n-3(n-4) foes this have an answer, no, or infinite solution

Answers

One solution. One. Ask me if you have any questions
14 + 3n = 8n - 3(n - 4)

I feel like the easiest way to find out how many solutions it has is to simply solve the equation.

So, simplify the equation.

14 + 3n = 8n - 3n + 12

Combine like terms.

14 + 3n = 5n + 12

Subtract 14 from both sides.

3n = 5n + 12 - 14

Subtract 5n from both sides.

3n - 5n = 12 - 14

Simplify.

-2n = -2

Divide both sides by -2.

n = 1

Therefore there is only one solution to this problem.
