Grace was given the description “three less than the quotient of a number squared and nine, increased by eight” and was asked to evaluate it when n = 6. Her work is shown below.

In which step did she make an error?
step 1
step 2
step 4
step 5

Answer:

B

Step-by-step explanation:

I'm pretty sure it's B. Sorry if I'm wrong.

Answer:

wouldn't it be B

Step-by-step explanation:

because the formula is 2pi r  but with the 2 at the bottom the pi r  would be at the top.

Answer:

30

Step-by-step explanation:

Lets use the formula BEDMAS:

-6 × -3 = 18 (Since two negatives equals a postive)

18 - 8 = 10

We have a first bracket done, so lets do the next one:

-6 ÷ -2 = 3

-----------

In the middle, the is a multiply symbol, so

10 × 3 = 30

----------

Have a good day :)

Part A:

(larger)

(multiply)

(32)

Part B:

you didnt give any context. But to turn pounds into ounces multiply it the pounds by 16 (2lbs. × 16 = 32oz.)

and once you have the total number of ounces divide it by how many ounces her mom drinks in a day (ex. 32÷4= 9) and if that number is larger than 7 then yes, theres enough coffee

Answer:

3. y=3x-4

4. -1/2x+6

Step-by-step explanation:

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

Answer:

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

The answer is 86

Following PEMDAS, which is:

parentheses

exponents

multiplication

division

addition

subtraction

I found that the answer was 86

Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

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

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Please let me know if you have any further questions.

--Answer--

50 + p + 75 = 150

--Explanation--

The total number of money he had originally is 150. If he is left with 75, that starts us with 150 = 75 ______.

He spend something that was 50 dollars, so add that to 75 which equals 125.

Subtract 125 from 150 and you get 25. 25 is the cost of the single DVD, so we'll make 25 "p."

The cost of the DVD box set, the single DVD, and how much he is left with equals how much money he had originally.

That would make it 50 + p + 75 = 150.

Answer: 6.8

Step-by-step explanation:

Add all of them, and then divide them by 8

Answer:

The mean is 6.75

Step-by-step explanation:

There are 8 numbers in the set. Add them all, and then divide by 8.

2 + 5 + 5 + 6 + 8 + 8 + 9 + 11 / 8=54/8=6.75

So, the mean is 6.75!

Answer:

n=2

Step-by-step explanation:

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.

Answer:

108

Step-by-step explanation:

So, to start, we can calculate the fuel used in March by using the following equation:

(40x240)/100

Which is 96. So the furnace burned 96 gallons of fuel in March and was left with 144 gallons. Now we need to find out how much of its remaining fuel it burned in April, so we use this:

(25x144)/100

Which is 36. So it burned another 36 gallons of fuel in April, leaving it with 108 gallons still in the tank.

Answer: i think is 108 i hope this help sorry.....

The scatter plot diagram that represents the data that is shown in the given table is; Attached below

We are told that;

the x-axis represents the beginning balance in thousands of dollars.

the y-axis represents the change in the bank account by hundreds of dollars.

Now, this means the values on the x-axis in plotting order from left to right with their corresponding y-values are;

x - values = 6, 4, 3, 1, 8, 3, 4, 5

y - values = 6, 5, 2, 5, 4, 8, 2, 3

Thus, to plot the scatter diagram, we will enter the corresponding x and y coordinate values which are seen in the scatter diagram attached.

Hello! I believe that I have the answer.

My answer: The total amount was $47.79.

8% of $37.50 is $3. $37.50 + $3 = $40.50.

18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.

Answer:

The distance between Points A and B is 1.

Step-by-step explanation:

Given that Point A is located at -0.75 and Point B is located at 1/4 on a number line, to determine which expression shows how to find the distance between points A and B the following calculation must be performed:

1/4 = 0.25

-0.75 + X = 0.25

X = 0.25 - (-0.75)

X = 0.25 + 0.75

X = 1

Therefore, the distance between Points A and B is 1.
