The domain of a function is always equal to which one of the following options?

Answer:

its the last choice

3-n=14

Step-by-step explanation:

3 less than a number is 14 tells u that u have to subtract 3 by a number which is represented with the letter N and that equals 14

(I'm in k12 too)

Hope this helps!

Answer: I think its 12 (could be wrong)

Step-by-step explanation:

12*16 in area is 96

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

A.

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

B.

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

C.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

D.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values

Answer: c

Step-by-step explanation:

5 is the answer.

What is a cuboid?

A cuboid is a rectangle, but in 3D form.

Do we calculate area or volume in a cuboid?

We calculate the volume for 3D shapes. For 2D shapes, area is used.

If/Then:

Now, if the volume of the cuboid is 24 units³ then:

x × x × y

Now, lets fit all our options to see which one is NOT the dimensions.

Option A:

x × x × 3 = 24 units³

x × x = 12 units³ ✔

This is possible.

Option B:

x × x × 4 = 24 units³

=> x × x = 6 units³ ✔

This is possible.

Option C:

x × x × 5 = 24 units³

=> x × x = 24/5 units³ ❌

This is not possible. This will be our answer.

Option D:

x × x × 6 = 24 units³

=> x × x = 4 units³✔

This is possible.

Conclusion:

So after working on our problem, we can conclude that C is our answer. Hoped this helped.

Answer:

$7000

Step-by-step explanation:

This problem seems scary at first sight, but don't be intimidated. It is actually pretty simple.

The column of equations (starting with 0.1d) at the right of T(d) is a list of option based on d, the taxable income. If d is less than or equal to (≤) 9875, than the equation is T(d) = 0.1d.

It shows that Noam has 90000 dollars for d, or the taxable income, and Betty has 120000 dollars.

Now, let's find the equations by plugging in 90,000 for d first.

90,000 is greater than 85, 526 and less than 163,300 (85, 526 ≤ 90,000 ≤ 163300).

Then we plug in 120,000 dollar to find the corresponding equation.

120000 is greater than 85, 526 and less than 163, 300 (85, 526 ≤ 120,000 ≤ 163300).

So the chosen equation is:  

T(d) = .24( d -85525) + 14605.5

Plug in the Noam's number for d

T(d) = .24(90,000 - 85, 525) + 14, 605.5

T(d) = .24(4475) + 14,605.5

T(d) = 1074 + 14,605.5

T(d) = 15, 679.5

Now Plug in Betty's number for d

T(d) = .24 (120,000 - 85, 525) +14, 605.5

T(d) = .24( 34475) + 14, 605.5

T(d) = 8274 + 14, 605.5

T(d) = 22, 879.5

We are finding how much more tax does Betty pay, so we subtract               15, 679.5 from 22, 879.5.

22, 879.5 - 15, 679.5 = 7200

Betty pays $7000 more tax than Noam does.        

Answer:

Step-by-step explanation:

4x+5+3x=68

x=9

Two angle that form a line is a linear pair, which mean its 180 degree

180-68=112

X=9

Missing angle is 112

All the angles sum up to 180

Answer:

Two opposite interior angles gives one exterior

3x + (4x+5) = 68

7x = 63

x= 9

therefore

for 3x = 27,. 4x+5=4(9)+5 =41

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Example

A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.

Try to solve the problem now.

The correct statistical question is,

''What are the speeds of the cars on the highway?''

Hence, Option B is true.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, By all the statements we get;

The statistical question is,

B. "What are the speeds of the cars on the highway?"

Since, it involves collecting data on a variable of interest (speed) from a group of individuals (cars on the highway).

Thus, Option B is true.

Answer:

\(\frac{18}{7}\)

Step-by-step explanation:

\(2\frac{4}{7}\)

→ Multiply 7 by 2 then add 4

7 × 2 = 14 + 4 = 18 ⇔ Numerator

7 ⇔ Denominator

Answer: 18/7

Explanation: To write a mixed number as an improper fraction, first multiply

the denominator times the whole number, then add the numerator.

So here, we multiply the denominator, 7, times the

whole number, 2, then we add the numerator, 4.

So we have (7 × 2) + 4 or 14 + 4 which is 18.

Finally, we put our new number over our

old denominator and we have our answer, 18/7.

So 2 and 4/7 can be rewritten as the improper fraction 18/7.

Answer:

49π or 153.94 to 2dp

Step-by-step explanation:

diameter=14

radius=7

equation for area= r^2 × π

7^2=49

49×π=49π

49π=153.93804002589

or 153.94 to 2dp

Answer:

153.93804003

Step-by-step explanation:

The area of a circle is: A= πr²

So we have to divide the diameter by 2 which is 7 and that will give us our radius

A= π(7)²

A= π(49)

A=153.93

Answer:

756

Step-by-step explanation:

Answer:

126x6= 756

My Bad If this took So Long, I Used long division To Explain The Concepts.

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 6 on the left side and the dividend 126 on the right side

Step 2:

The divisor (6) goes into the first digit of the dividend, 0 times

Step 3:

Multiply the divisor by the result in the previous step (6 x 0 = 0)

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1- 0 = 1)

Step 5: Move down the 2nd digit of the dividend

Step 6: The divisor 6 goes into the bottom number 12, 2 times

Step 7: Multiply the divisor by the result in the previous step 6 x 2 = 12

Step 8: Subtract the result in the previous step from the number written above it (12 - 12 = 0)

Step 9: Move down the last digit of the dividend 6

Step 10: The divisor 6 goes into the bottom number 6,  1 time

Step 11: Multiply the divisor by the result  in the previous step 6 x 1 = 6

Step 12: Subtract the result in the previous step from the number written above it. (6 - 6 = 0)
